Retinol vs Tretinoin: The Complete Guide to Retinoids for Perimenopausal Skin | Dr. Mamina Turegano

Why It Matters

Clear guidance on dosing, ramping, and formulation helps consumers and clinicians balance efficacy and tolerability, shaping demand for gentler OTC retinoid formulations and influencing prescribing patterns between OTC retinal/retinol products and prescription tretinoin. This has implications for skincare brands, pharmacies, and regulatory differences across markets.

Summary

Dr. Mamina Turegano explains retinoids as a spectrum—retinol (weaker) converts to retinal(dehyde) and then to retinoic acid (tretinoin, prescription Retin-A)—and stresses that formulation and concentration determine real-world strength and tolerability. U.S. dermatology recommendations favor near-daily use based on long-term wrinkle and tone studies, while some EU practitioners use gentler, less frequent approaches. For consumers, she recommends starting based on skin type (retinol/retinal for dry or sensitive skin, low‑strength tretinoin possible for oilier skin), onboarding gradually (start 2x/week, ramp to 5–6 nights), using a pea-sized dose applied in dots, and layering moisturizer or the “sandwich” method to reduce irritation. Product choice should prioritize supportive formulation (ceramides, hyaluronic acid, niacinamide) rather than only the named retinoid ingredient.

Original Description

Retinol, retinal, tretinoin, Retin-A — they all sound the same and the confusion is completely understandable. But getting this right is one of the most impactful things you can do for aging skin.

Triple board-certified dermatologist @dr.mamina Dr. Mamina Turegano walks through the full retinoid hierarchy: what each one does, how strong each one is, and which to start with depending on your skin type. She covers the sandwich method for sensitive skin, short-contact therapy for people who can't tolerate it directly, how to onboard without irritation, which actives you should never pair with a retinoid, and why the French dermatologist telling you to use it once a week is probably wrong.

If you've ever bought a retinol and given up on it, this is the video you needed first.
