[PMID: 40319989 DOI: 10.1016/j.actbio.2025.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2024] [Revised: 04/23/2025] [Accepted: 05/01/2025] [Indexed: 05/07/2025]
Abstract
Snails are mollusks or shelled gastropods found everywhere on Earth. Biologically, snail mucus can be described as a multifunctional natural polymeric gel with adhesive and antimicrobial properties, rendering it a promising ingredient in pharmaceutics and biomedical applications. These properties have been exploited in cosmetics and dermatology applications over the last few years. However, the exploration of snail mucus for other biomedical applications, e.g., wound healing and drug delivery, remains new and very promising. Against this backdrop, this review explores the potential of snail mucus for a wide spectrum of biomedical applications, ranging from wound healing to cancer treatment to regenerative engineering. It will be emphasized how its application in wound healing has gained traction owing to its antimicrobial and anti-inflammatory properties. Beyond wound care, snail mucus has been investigated as a drug delivery vehicle in treating diabetes and targeted cancer therapies. While further extensive research and clinical trials are needed to solidify the efficacy of snail mucus as a biomaterial, this review will shed light on the prospect of using snail mucus alone and in combination with other natural or synthetic biopolymers as soft materials for widespread biomedical applications. STATEMENT OF SIGNIFICANCE: Exploring snail mucus as a biomaterial across various fields, including oncology, drug delivery, cosmetics, antibacterial properties, and wound healing, presents a fascinating avenue for zootherapy research. This review provides an in-depth account of the recent developments in snail mucus' potential for a broad spectrum of biomedical applications, from wound healing to cancer treatment and regenerative engineering. It highlights the growing interest in mucus' use in wound healing, attributed to its antimicrobial and anti-inflammatory properties. It has also been investigated as a drug delivery vehicle for diabetes treatment and targeted cancer therapies. The impact of such research is significant, as it could lead to the creation of innovative biomaterials for a wide range of applications, revolutionizing the field of biomaterials.

Abstract
INTRODUCTION Radiotherapy (RT) is a technique widely used in oncology, acquiring special prominence in head and neck cancer (HNC). RT of HNC may be associated with secondary effects including skin reaction, being dermatitis the most common radio-induced side effect during treatment. PURPOSE The use of a wide variety of agents is reported to handle skin toxicity. The aim of the present work is to evaluate the different level-concentration of Snail Cryptomphalus Aspersa (SCA) that best protect from radiation-induced radiodermatitis in HNC. MATERIAL AND METHOD We performed a single institutional pilot study to assess the skin toxicity with 0%, 5%, 10% and 15% SCA concentration during RT treatment and 1 and 3 months after the treatment finished according to the Radiation Therapy Oncology Group (RTOG) scoring. A total of 72 patients with HNC diagnosis who received RT with/without Chemotherapy (Ch) between January of 2018 and June of 2020 were assessed. Radiodermatitis grade was stastistically correlated with the SCA level-concentration and with the influence of extranodal extension status (ENE). RESULTS A reduction in the rate of grade ≥ II patients' dermatitis was dependent on SCA level-concentration. We found that with higher SCA level-concentration (10 and 15%, patients had 34 and 38% grade ≥ II respectively), this was less than with 0 and 5% SCA level-concentration where a 58% radiodermatitis grade ≥ II was found by Cox regression analysis; p = 0.017 and p = 0.045 respectively. CONCLUSION We could conclude that the application of a 10-15% SCA level-concentration after adjusting by ENE, was the best concentration to reduce the rate of grade ≥ II radiodermatitis.

Abstract
Platelet-rich plasma (PRP) with skin booster is a popular treatment for improving skin quality and reducing the signs of aging. However, few studies have evaluated its clinical efficacy in patients with aging face. This study aimed to evaluate the clinical efficacy, adverse reactions, and follow-up results of targeted injection of PRP with skin booster in treating patients with aging face. The study included 80 patients treated with targeted injection of PRP with skin booster from July 2022 to February 2023. The doctors compared the changes of the patients' facial skin indicators, quality of life, and satisfaction with their appearance before and after treatment, and analyzed the clinical efficacy, adverse reactions, and follow-up results of the patients after treatment. After one course of treatment, the patients' facial skin indicators, quality of life, and satisfaction with their appearance improved significantly, with P < 0.05. The total clinical effective rate was 88.75%, and the incidence of adverse reactions was 6.25%. After half a year of follow-up, 48.75% of the patients were willing to receive further treatment, and their facial soft feel, natural expression, and self-feeling comfort had significantly improved. Targeted injection of PRP with skin booster is an effective and safe treatment for improving facial skin symptoms such as coarse pores and wrinkles in patients with aging face. The results of this study provide evidence for the clinical use of PRP with skin booster in aesthetic medicine.

Abstract
Skin, as the outermost protective barrier of the body, becomes damaged with age and exposure to external stimuli. Dermal fibroblasts age and undergo apoptosis, which decreases collagen, collagen fibers, elastic fibers, hyaluronic acid, etc., leading skin to loss of elasticity and appearance of wrinkles. Skin aging is complex, involving several biological reactions,and various treatment methods are used to treat it. This review focuses on the importance of autophagy and cell proliferation in skin anti-aging, summarizes research progress on skin anti-aging by regulating autophagy and promoting the proliferation of dermal fibroblasts, and discusses future directions on skin anti-aging research.

Abstract
INTRODUCTION In recent years, several non-invasive imaging methods have been introduced to facilitate studies in dermatology and cosmetic research, almost completely replacing invasive methods such as biopsy. Imaging devices have proven to be useful tools in skin analysis and therapy monitoring. This review aimed to investigate the most recent studies in cosmetic dermatology the imaging technology and methods that are being used to assess skin characteristics and summarize its fundamentals, possible applications, advantages, and limitations, and to give a future perspective to the clinical trials. EVIDENCE ACQUISITION For that, a literature review was carried out in the main scientific database platforms and the studies associating skin image analysis with dermatology and cosmetic research were selected and discussed. EVIDENCE SYNTHESIS It was possible to infer that skin image analyses are not only practical and effective, but have also become increasingly essential for the skin sciences. The in vivo and real-time image analyses allow a more complete evaluation and the follow-up of the same region for different periods. It was also possible to observe that macroscopic, microscopic, and mesoscopic imaging methods are complementary, allowing different approaches in the same study. CONCLUSIONS These technologies are expected to evolve more and more quickly in the near future.

Abstract
BACKGROUND Snail mucin is becoming increasingly popular for its wide range of ingredients and potential benefits. Snail extract's widespread appearance in cosmetic formulations encourages an investigation into the medical and cosmetic benefits. AIMS This study aims to explore current literature on the variety of snail mucin applications. Specifically, we present a review of the uses, global market estimates and projects, and limitations to snail mucin. METHODS A literature search was conducted on PubMed reviewing snail mucin and their application in medical and dermatologic fields examining their uses. Economic reports were also investigated for Global Market estimates. RESULTS The therapeutic use of snail mucin in medical fields has been studied as antimicrobial agents, drug delivery vehicles, antitumor agents, wound healing agents, and biomaterial coatings among others. Additionally, the use in cosmetic fields includes antiaging, hydrating, anti-acne, scarring, and hyperpigmentation treatments. It is important to highlight that most studies conducted were preclinical or small clinical studies, stressing the need for additional large-scale clinical trials to support these claims. Investigations into the global market found estimates ranging from $457 million to $1.2 billion with upward projections in the upcoming decade. Limitations include ethical habitats for collection, allergy investigation, and missing clinical studies. CONCLUSIONS The findings presented here emphasize the expanding uses of snail mucin and its ingredients alongside a growing market cosmetic industry should consider. We also emphasize the need for appropriate clinical trials into the stated benefits of snail mucin to ensure consumer safety and ethical extraction of mucin.

Abstract
The snail mucus provides several functions and is increasingly being exploited for medicinal and cosmetic purposes. This study aimed to determine the chemical profile of two snail mucus extracts: the garden snail (Helix aspersa) and the desert snail (Eremina desertorum). In addition, it elucidates the antityrosinase, antioxidant, and anticancer activities against the human cancer cell line epithelioid carcinoma (Hela). The mucus was extracted from the pedal glands of garden snails (H. aspersa) and desert snails (E. desertorum). 2,2-Diphenyl-1-picrylhydrazyl assay and the content of catalase, glutathione-S-transferase, superoxide dismutase, and reduced glutathione were utilized to assess the antioxidative screening activity of the mucus extracts. Besides a tyrosinase inhibitor assay, anticancer activity on cervical cancer cells (Hela) was studied. Additionally, the two mucus samples' total protein, total lipid, fatty acid, and amino acid profiles were compared. The mucus from both snails exhibited antioxidant activity. E. desertorum is more effective in inhibiting tyrosinase activity and has better scavenging activity than H. aspersa mucus extract. Both extracts revealed inhibitory activity against Hela cells, with insignificant differences. Moreover, the results indicated higher protein, lipids, and fatty acids mucus content of E. desertorum extract than those of H. aspersa mucus extract. Both snail slimes' obtained different biological activities, and amino acid contents could be related to their specific functions and beneficial for medical applications, especially antihyperpigmentation.

Abstract
BACKGROUND Cosmeceutical products are an important therapeutic option for facial rejuvenation. Of these, topical application of growth factors has been shown to increase dermal collagen synthesis, improve skin texture, and reduce fine lines and wrinkles. Limited data exist for the use of growth factors in combination with microneedling. OBJECTIVE This prospective, single-center, uncontrolled study evaluated the efficacy of topical growth factor treatment in conjunction with transdermal delivery of growth factors via home-based microneedling for facial skin rejuvenation. PATIENTS/METHODS Eleven healthy female individuals aged 33-61 years, with mild-moderate facial wrinkling were included in the study. Over 3 months, participants received twice-daily application of a topical recombinant human growth factor preparation (SkinGenuity® Regenerative and Reparative Serums) along with twice-weekly transdermal delivery of growth factors using a home-based microneedling (0.2 mm) device. Objective skin analysis (VISIA® ) and a subjective patient-reported outcome (FACE-Q® ) assessment measuring satisfaction with appearance were performed at baseline and after 3 months. RESULTS Objective skin analysis showed a significant improvement in skin texture (17.6%, p < 0.001), wrinkles (17.3%, p < 0.001), red areas (12.4%, p =0.004), and brown spots (6.0%, p =0.03) at 3 months follow-up. FACE-Q scales showed a significant improvement from baseline, including satisfaction with skin, facial appearance, nasolabial folds, cheeks, and lower face/jawline (all p ≤ 0.02). Numerical improvement in adverse effects related to skin was also observed (p = 0.07). No serious adverse effects were reported. CONCLUSIONS Three months of twice-daily topical growth factor treatment in conjunction with transdermal delivery of growth factors via microneedling improved skin analysis parameters and participant-reported outcome measures, indicative of facial skin rejuvenation.

Abstract
Background Hypertrophic scarring after burn injury is one of the greatest unmet challenges in patients with burn injuries. A better understanding of the characteristics of scar maturation and early prediction of the long-term outcome of scarring are prerequisites for improving targeted therapies and pivotal for patient counselling. Methods Repeated measurements of scar stiffness in 11 pediatric patients were performed over the course of 1 year using 2 suction devices, the Cutometer and the Nimble. In addition, the observer pliability score of the Patient and Observer Scar Assessment Scale was applied. This longitudinal study allowed quantification of the ability of each of the measured parameters to reflect scar maturation, as indicated by change in skin pliability/stiffness, over time (using linear regression); the ability to distinguish individual patients (intraclass correlation coefficient (ICC)); the correlation of the devices (Spearman correlation coefficient); and the ability to predict long-term scar maturation based on early scar assessment (using receiver operating characteristic). Results All the tools used showed significant longitudinal decrease of scar stiffness from 3 months until 12 months after the injury. The Nimble (ICCpatient Nimble = 0.99) and the Cutometer (ICCpatient Cuto = 0.97) demonstrated an excellent ability to distinguish between individual patients. The Nimble seemed to be able to predict the 12-month pliability of scars based on early (3-month) measurements (area under the curve (AUC)12m POSAS = 0.67; AUC12m C = 0.46; AUC12m N = 0.79). Conclusions The results of this preliminary study suggest that all 3 tools provide suitable means to quantify alterations in scar stiffness over time. Initial evidence suggests the Nimble is most favorable for predicting changes in stiffness associated with long-term scar maturation. Further studies with a larger sample size are required to validate tissue suction as a clinical tool for analysis of changes of scar stiffness over time.

Abstract
OBJECTIVE Snails secrete different types of mucus that serve several functions, and are increasingly being exploited for medical and cosmetic applications. In this study, we explored the protein pattern and compared the biological properties of the mucus secreted from the mantle collar and foot of two snail species, Lissachatina fulica and Hemiplecta distincta. RESULT Protein profile showed a different pattern between the two species and between the two secretory parts. The mantle-specific protein bands were further characterized and among them was an antibacterial protein, achacin. Accordingly, the mucus from the mantle exhibited the higher antibacterial activity than that from the foot in both snail species. The mucus from H. distincta, first reported here, also showed antibacterial properties, but with a lower activity compared to that for L. fulica. Snail mucus also exhibited anti-tyrosinase activity and antioxidant activity but with no significant difference between the foot and mantle mucus. These results indicate some different protein compositions and biological activities of snail slime from the mantle and foot, which might be associated with their specific functions in the animal and are useful for medical applications.

BACKGROUND Ablative fractional laser generates a regulated skin damage, which secondarily improves skin aging. AIMS The main objective of the present study was to figure out if the adverse effects induced by laser and the skin recovery could improve with the application of a cosmetic product based on the secretion of Cryptomphalus aspersa (SCA). PATIENTS/METHODS A prospective double-blind controlled study with vehicle in 10 patients with skin aging. The patients received one session of fractional ablative CO2 laser, and the formulation with SCA 40% was applied immediately and maintained throughout the 21-day duration of the study. The active treatment (SCA) was applied to one hemifacial area and vehicle to the other, and the patient acting was her own control. Clinical evaluations, dermoscopy, photography, and other parameters like cutaneous hydration, elasticity, and wrinkles were evaluated. In addition, the severity of the adverse effects was evaluated. RESULTS Significant greater decrease in the density of microcolumns produced by laser was detected on the active-treated side, indicating greater and faster postprocedure recovery compared to the vehicle-treated side. In addition, side effects were reduced and some antiaging effects were more apparent on the side treated with SCA 40%. CONCLUSION SCA 40% applied immediately after ablative laser, and during the next days, it can accelerate laser-induced damage regeneration. In addition, SCA improves the cosmetic outcome after laser application.

Abstract
BACKGROUND: Two extracts derived from the gastropod Cryptomphalus aspersa have been shown to have dermal regeneration properties: SCA® (secretion filtrate) with fibroblast growth factor-like activity and IFC®-CAF (cellular activating factor), a snail egg extract with skin stem cell activation activity. OBJECTIVE: The objectives of this study were to evaluate the synergic antiaging activity and tolerability of SCA and IFC-CAF in a combined regimen compared to vehicle as a placebo control. METHODS: A three-month, single-center, double-blinded, randomized, vehicle-controlled trial assessed the effects of a daily skincare routine divided into two treatment phases, as follows: intensive (1 month) and maintenance (2 months). Fifty women, aged 45-65 years, with signs of photoaging were randomized to receive either the active ingredients (n=30) or vehicle (n=20). Clinical evaluations included objective measurements of barrier function and skin hydration, elasticity, and color/brightness. Subjective assessments were conducted according to the Rao-Goldman and Glogau scales for wrinkles, the Patient Global Assessment (PGA) scale and Investigator Global Assessment (IGA) scale. RESULTS: Subjects in the active treatment group experienced reductions in transepidermal water loss and significant improvements in skin roughness, firmness, and elasticity. Both groups showed significant improvements in fine lines and wrinkles. PGA and IGA assessments indicated greater improvement in the active treatment group. CONCLUSION: The active snail extract treatment appears to be effective in improving signs of skin aging in women 45 to 65 years old. Larger randomized, controlled studies are needed to confirm our results.

Truchuelo MT, Vitale M. A cosmetic treatment based on the secretion of Cryptomphalus aspersa 40% improves the clinical results after the use of nonablative fractional laser in skin aging. J Cosmet Dermatol 2019; 19:622-628. [PMID: 31222893 PMCID: PMC7027885 DOI: 10.1111/jocd.13052] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2019] [Revised: 04/28/2019] [Accepted: 05/13/2019] [Indexed: 11/29/2022]
Abstract
Introduction The main purpose of this study was to evaluate whether the application of a cosmetic treatment based on the secretion of Cryptomphalus aspersa (SCA) enhances the clinical results, tolerance, and skin regeneration after nonablative laser treatment in patients with moderate photoaging. Methods Randomized, double‐blind, split‐face trial in 20 patients with moderate aging. Two sessions with fractional nonablative laser were performed, and the cosmetic treatments (SCA 40% on one hemiface and vehicle on the other) were applied immediately after laser session and daily during the study (28 days). Tewameter, Cutometer, Visioscan, VisioFace, photography, dermoscopy, and clinical evaluation were assessed. Side effects were also evaluated. Results A significant decrease in the density of microcolumns (25%, 71%, 32%, and 61% less density, respectively, at T3 P = 0.008, T7 P = 0.002, T22 P < 0.001, and T24 P < 0.001) was observed on the side treated with SCA compared to the vehicle‐treated side. Cutaneous elasticity, area of wrinkles, and hydration on the SCA‐treated side also showed a significant improvement compared to the vehicle‐treated side. Both the researcher and patients observed a significant improvement on the side treated with SCA compared to the vehicle‐treated side. Significantly fewer side effects (erythema, burning, and dryness) were also detected. Conclusion A cosmetic product with SCA 40% applied immediately after laser and for a period thereafter enhances and accelerates repair of damage produced by the laser and significantly reduces related adverse effects. In addition, SCA treatment could improve clinical results. In conclusion, we suggest that SCA enhances the effectiveness of laser in the treatment of cutaneous aging.
