Retinoids in Cosmetics — FDA Labeling Guidance: Retinol and its derivatives are permitted in cosmetics and have demonstrated efficacy in reducing the appearance of fine lines, wrinkles, and improving skin texture through increased cell turnover.

CTPA — Tocopherol (Vitamin E) in Cosmetics: Tocopherol and its esters are widely used antioxidants in cosmetic formulations. The CTPA confirms that tocopherol has an excellent safety profile in cosmetic applications and provides meaningful protection against oxidative degradation of skin lipids.
Methylparaben
Benefits

Potential concerns
- !Weak estrogenic activity — potential endocrine disruption at high exposures

Sources
SCCS Safety Opinion on Parabens — Methylparaben and Ethylparaben: The SCCS concluded that methylparaben is safe at a maximum concentration of 0.4% (as acid) in finished cosmetic products. The body of evidence does not support endocrine disruption concerns at these concentrations for the general population.
Korean MFDS Standards for Parabens in Cosmetics: Korean MFDS permits methylparaben at up to 0.4% in cosmetics and requires labelling disclosure. The MFDS advises that paraben safety data for infants under 36 months is insufficient and recommends caution.
