Science
Mechanism of Action
As a lipophilic antioxidant, Beta-Carotene primarily quenches singlet oxygen and neutralizes free radicals to prevent lipid peroxidation within the cellular membrane. Once absorbed, it undergoes partial conversion into retinal, facilitating cellular renewal and collagen synthesis, while its natural pigment helps absorb UV radiation and modulate tyrosinase activity to manage hyperpigmentation.

Key findings
- 01 Topical application yielded a 20% increase in stratum corneum hydration and a 30% reduction in surface roughness.
- 02 Supplementation significantly elevated Type I procollagen mRNA levels, leading to measurable improvements in elasticity and wrinkle depth.

Dusting Analysis
Because Beta-Carotene acts as a potent natural colorant, brands often include it at very low levels (under 0.01%) just to achieve a 'healthy' product glow. For therapeutic antioxidant and pro-Vitamin A benefits, a concentration of at least 0.1% is required.
