Clinical efficacy and safety of nano-microneedle-assisted phenylethyl resorcinol for the treatment of infraorbital dark circles

Efficacy and Safety of Introduction Timolol Maleate by Manometer Microneedles among Infantile Hemangioma: A Retrospective Study in China

OBJECTIVE

 The objective of the study was to compare the effective rate, cure rate, adverse reaction rate, and effective time of three methods in the treatment of infantile hemangioma, hoping to provide reference for improving the clinical therapeutic effect.

METHODS

 This is a retrospective study of 307 infantile hemangioma patients admitted to the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, from January 2014 to October 2021. The patients were divided into three groups. In group A, timolol maleate solution was introduced by the nano-microneedle technique (97 cases); in group B, timolol maleate drops dipped in medical swabs were applied (107 cases); and group C patients took propranolol orally (103 cases). The effective rate, cure rate, adverse reaction rate, and effective time of treatment were recorded and compared.

RESULTS

 The total effective rate, total cure rate, and total adverse reaction rate of the three groups were 87.6, 65.2, and 9.4%, respectively. The results showed that the effective and cure rates of group A were higher than those of group B (92.8 and 76.3%, respectively; p < 0.05), the adverse reaction rate of group C was higher than that of group B (17.5%, p < 0.05), and the effective time of group A was shorter than that of groups B and C. In most patients, symptoms significantly improved within 2 months (p < 0.05).

CONCLUSION

 Timolol maleate introduced by nanometer microneedles is an effective and safe treatment for superficial hemangioma in infants with the highest effective and cure rates, lower incidence of adverse reactions, and the shortest effective treatment time.

TFOS Lifestyle: Impact of cosmetics on the ocular surface

In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Recent advances in the design and discovery of synthetic tyrosinase inhibitors

Tyrosinase is a copper-containing metalloenzyme that is responsible for the rate-limiting catalytic step in the melanin biosynthesis and enzymatic browning. As a promising target, tyrosinase inhibitors can be used as skin whitening agents and food preservatives, thus having broad potential in the fields of food, cosmetics, agriculture and medicine. From 2015 to 2020, numerous synthetic inhibitors of tyrosinase have been developed to overcome the challenges of low efficacy and side effects. This review summarizes the enzyme structure and biological functions of tyrosinase and demonstrates the recent advances of synthetic tyrosinase inhibitors from the perspective of medicinal chemistry, providing a better understanding of the catalytic mechanisms and more effective tyrosinase inhibitors.
