The mechanism behind Tretinoin is precise: Active form of vitamin A — binds retinoid receptors directly; no conversion needed. That specificity is what separates it from broader-category ingredients that work in less targeted ways.
The scientific name is Tretinoin (Retinoic Acid). Active form of vitamin A — binds retinoid receptors directly; no conversion needed. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 0.025–0.1%. Best suited to all (under dermatologist supervision) skin. Primary applications: anti-aging, acne, hyperpigmentation, texture.
Works well with: Niacinamide (reduces irritation), ceramides, moisturisers. Avoid combining with: AHAs, BHAs, benzoyl peroxide, vitamin C (same step).
Prescription only in most countries; most evidence-based retinoid; potent irritation possible.
