Science

Mechanism of Action

This extract functions as a powerful antioxidant, neutralizing free radicals induced by UV radiation and environmental pollutants, thereby safeguarding skin cells from oxidative stress and mitigating premature aging. Its anti-inflammatory properties work to calm and reduce skin redness, irritation, and itchiness, aiding in recovery from sensitivities. Rich in hydrating polysaccharides and alginates, it boosts the skin's moisture retention, strengthening the barrier for a plumper, more radiant complexion. Furthermore, it supports collagen synthesis, contributing to improved elasticity, reduced fine lines, and enhanced overall skin health and youthfulness. The presence of compounds like phenols, beta-carotene, and the sulfated polysaccharide 'ulvan' also suggests potential for tyrosinase inhibition, offering skin brightening effects, and supporting skin repair and immune modulation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Ulva lactuca Extract is generally regarded as non-toxic and gentle for topical application, classified as 'Irritant Free' and 'Dye Free' by SkinSAFE, and supported by INCIdecoder's assessment of low irritancy. While often cited as non-comedogenic, some historical data, potentially derived from older rabbit ear test methods, indicates a 'Moderate Potential Pore Clogger' or a comedogenic score of '3 out of 5' for certain individuals, creating conflicting information on its pore-clogging potential. No specific Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) reports were identified.
