Retinoid (Vitamin A)
Vitamin A derivatives (retinol, retinaldehyde, adapalene) that speed cell turnover and stimulate collagen — the most evidence-backed ingredient for fine lines, texture, and acne.
How to use it
Start 2–3 nights a week and build up. Use at night, buffer with moisturizer if it stings, and always wear SPF the next morning.
Avoid combining with
Benzoyl peroxide oxidizes and deactivates most retinoids, cancelling their benefit.
→ Use benzoyl peroxide in the AM and the retinoid at night, or on alternate days.
Both speed cell turnover — together they can over-exfoliate and irritate.
→ Alternate nights, or use the AHA in the AM and the retinoid at night.
Retinoid + BHA can over-exfoliate and compromise the barrier.
→ Alternate nights rather than layering in the same session.
