Yes, you can often use over-the-counter (OTC) and prescription skincare products together, but it's important to do so carefully. Here's what to keep in mind:
✅ When It’s Safe:
-
Different purposes: Using a prescription retinoid (like tretinoin) and an OTC moisturizer or sunscreen is common and safe.
-
Layered routines: Many people use a gentle OTC cleanser and then apply a prescribed treatment.
-
Dermatologist guidance: If your doctor recommended both, they’ve likely considered interactions.
⚠️ Be Cautious With:
-
Multiple actives: Using prescription-strength retinoids and OTC actives like AHAs, BHAs, or benzoyl peroxide at the same time can cause irritation, dryness, or even worsen your skin barrier.
-
Mixing exfoliants: Don’t combine too many exfoliating products (e.g., glycolic acid + retinoid + salicylic acid).
-
Layering too fast: Introduce one product at a time to monitor your skin’s reaction.
💡 Tips:
-
Alternate nights: Use a retinoid one night and an exfoliating acid the next.
-
Buffer irritation: Apply moisturizer before or after prescription products if you feel sensitive.
-
Patch test new combinations before applying to your whole face.
