CIS-RETINOIC ACID.

Avoid CAS 4759-48-2 / ANTI-SEBUM

Cis-retinoic acid, also known as isotretinoin, is a potent retinoid primarily used as a prescription medication for severe acne. While experimental topical applications show promise for acne and photodamaged skin, its use in over-the-counter cosmetics is highly restricted due to regulatory hurdles.

Cell-communicating ingredient Anti-acne

Science

It significantly reduces sebaceous gland size and sebum production, normalizes keratinization to prevent pore clogging, and possesses anti-inflammatory properties. This creates an unfavorable environment for C. acnes and directly induces sebaceous gland apoptosis.
