A Topical Formulation Containing Macrocystis Pyrifera Ferment for Managing Barrier Damage After Mild-Moderate Skin Disruption from Cosmetic Dermatologic Procedures.

Objective: The primary objective of these studies was to evaluate the potential of a serum containing Macrocystis pyrifera ferment (MPF-Serum) to both strengthen the barrier of intact skin and enhance barrier recovery after a non-ablative laser procedure or glycolic acid chemical peel.

Methods: Two whole-face clinical trials and three split-face, randomized, controlled clinical trials were conducted in women aged 31 to 65 years. The effect of MPF-Serum on barrier integrity and strength was assessed by transepidermal water loss measurement before and after controlled tape-stripping experiments and in-clinic 70% glycolic acid peel and non-ablative laser procedures.

Results: Application of MPF-Serum twice daily for eight weeks on intact skin significantly increased mean moisturization by 16 percent and improved barrier integrity by 11 percent (p≤0.05 for both). Likewise, barrier strength across 8x tape-stripped skin showed a 30-percent improvement after eight weeks of treatment. In studies involving non-ablative laser procedures, MPF-Serum pre-treatment or post-treatment improved post-procedure barrier recovery to a greater extent than standard moisturizer. Likewise, in a study involving 70% glycolic peel, MPF-Serum pre-treatment improved post-procedure barrier recovery to a greater extent than no pre-treatment.

Limitations: These clinical studies were conducted at a limited number of sites, with limited sample sizes and populations.

Conclusion: This topical MPF-Serum effectively improves barrier integrity and strength and helps to reduce recovery time from dermatologic procedures such as glycolic acid peel and laser treatments.
