Multicenter evaluation of a topical antioxidant serum

Area of Science:

• Dermatology and Cosmetology
• Biochemistry of the Skin
• Extracellular Matrix Remodeling

Background:

• A novel antioxidant serum containing sodium ascorbate (a Vitamin C derivative) was developed to treat facial photodamage.
• The serum aims to preserve elastin and minimize skin irritation.
• Previous research established the foundational science behind this formulation.

Purpose of the Study:

• To validate the efficacy and tolerability of the new antioxidant serum.
• To assess the serum's impact on moderate to severe facial photodamage.
• To confirm the product's ability to preserve elastin and reduce irritation.

Main Methods:

• An open-label, multicenter clinical study conducted over 5 months (March-July 2023).
• Thirty-six participants (Fitzpatrick skin types II-V) used the serum twice daily for 12 weeks.
• Evaluations included photodamage severity, tolerability, subject/investigator assessments, biopsies, and photography.

Main Results:

• Significant improvements in all facial photodamage parameters were observed after 12 weeks.
• Excellent tolerability and subject satisfaction were maintained throughout the study.
• Histological analysis showed increased elastin fibers and stimulated collagen production.

Conclusions:

• The novel antioxidant serum is safe and effective for treating facial photodamage.
• The serum stimulates the production of elastin and collagen in the skin's extracellular matrix.
• This formulation offers a promising approach to skin rejuvenation and repair.
