Ultraviolet Protection From a Patented Amino Acid Complex Technology

Area of Science:

• Dermatology
• Biochemistry
• Photobiology

Background:

• Ultraviolet (UV) radiation causes significant skin damage, including collagen degradation and inflammation.
• Effective photoprotection and DNA repair mechanisms are crucial for maintaining skin health.

Purpose of the Study:

• To evaluate the UV protection and repair capabilities of a patented Amino Acid Complex (AAComplex).
• To assess AAComplex's efficacy both as an ingredient and within topical formulations.

Main Methods:

• Assessed AAComplex's effect on collagen I synthesis in UVA-irradiated dermal fibroblasts.
• Quantified biomarkers of inflammation (TNF-alpha, histamine, MMP-1) in UVA-exposed skin explants treated with AAComplex lotion.
• Evaluated AAComplex serum combined with sunscreen on epidermal equivalents for effects on DNA damage (thymine dimers), cell proliferation (Ki-67), and protective markers (IL-1alpha, filaggrin, Nrf2).

Main Results:

• AAComplex prevented UVA-induced decrease in collagen I synthesis.
• AAComplex lotion significantly reduced UVA-induced histamine, TNF-alpha, and MMP-1 levels.
• A regimen of sunscreen plus AAComplex serum demonstrated significant reduction in IL-1alpha, complete Ki-67 recovery, and stimulated filaggrin and Nrf2, with no observable thymine dimers.

Conclusions:

• AAComplex offers UV protection and damage repair at the ingredient level and in formulations.
• A combined regimen of sunscreen and AAComplex serum provides optimal skin protection against UV damage.
