Improvements in skin quality parameters in postmenopausal participants after use of topical growth factor serum

Regenerative Skincare Technologies Derived From Human Fibroblasts: Growth Factors and Exosomes for Transformative Outcomes

BACKGROUND

Since the early 2000s, human fibroblast conditioned media (HFCM) has been used in topical growth factor skincare to support skin regeneration and skin rejuvenation. Human fibroblast conditioned media contains the fibroblast secretome including growth factors as well as exosomes. The potential benefits of topically applied exosomes are gaining interest in the medical aesthetic field.

OBJECTIVE

This article aims to summarize the preclinical and clinical data available on regenerative HFCM-based topical skincare with a focus on studies investigating products applied to improve overall facial skin rejuvenation and/or after in-office cosmetic procedures. In addition, available data on fibroblast-derived exosomes will be covered.

METHODS

A focused literature review was conducted to provide an overview of evidence on HFCM-based topical skincare.

RESULTS

Human fibroblast conditioned media-based skincare significantly reduces signs of skin aging including photodamage, coarse lines and wrinkles, and sagging. After in-office cosmetic procedures, HFCM-based skincare can stimulate skin recovery and reduce downtime as well as provide skin quality benefits to enhance overall treatment outcomes. Application of purified exosomes from HFCM also demonstrated significant improvements in multiple skin aging parameters.

CONCLUSION

Human fibroblast conditioned media combines naturally secreted fibroblast-derived growth factors and exosomes that stimulate skin regeneration and rejuvenation as evidenced by a variety of assays and assessments including in vitro preclinical studies, clinical investigator grading, instrumentation measurements, biopsy analyses, and patient-reported outcomes.

Efficacy and tolerability of a novel cosmetic growth factor serum when used as part of biweekly diamond tip hydradermabrasion treatments on facial skin

BACKGROUND

Growth factor preparations have demonstrated effectiveness in reversing age-related changes in facial skin. TNS® Advanced+ Serum (TNS A+ Serum; SkinMedica®, Allergan Aesthetics, an AbbVie Company) and TNS Advanced+ Pro-Infusion Serum for DiamondGlow® (DG-TNS A+; Allergan Aesthetics) combine growth factor technology with active botanical ingredients to target signs of skin aging.

AIMS

This prospective clinical study evaluated the effectiveness and tolerability of biweekly facial hydradermabrasion (DiamondGlow [DG]; Allergan Aesthetics) plus DG-TNS A+ combined with at-home topical TNS A+ Serum.

METHODS

Females aged 25-65 years with mild to severe facial photodamage received 6 biweekly DG plus DG-TNS A+ in-office treatments with at-home twice-daily TNS A+ Serum for 12 weeks. Investigator-assessed clinical grading of multiple skin attributes, subject self-assessments, instrumentation measurements, and clinical grading of irritation parameters (0-3, none to severe) were conducted at Visit 1, Day 3, and biweekly from Weeks 2-12.

RESULTS

Twenty-nine women (Fitzpatrick skin types II-VI; 52% White, 41% African American) were enrolled. Immediate significant improvements after 1 DG plus DG-TNS A+ treatment were observed for fine lines/wrinkles, skin smoothness (visual and tactile), radiance, and hydration (all p ≤ 0.004). From Weeks 6-12, all investigator-assessed parameters showed significant improvements versus baseline (all p ≤ 0.002 at Week 12). Mean tolerability scores were <1 across parameters. All subjects (100%) were satisfied with results at Weeks 2-12.

CONCLUSIONS

The combination of biweekly hydradermabrasion plus DG-TNS A+ with at-home TNS A+ Serum treatments was well tolerated and produced immediate, progressive improvement in multiple signs of photoaging in facial skin.
