This is a dual action product (anti-aging & acne). If you are looking for just an acne product our Benzoyl Peroxide Lotion 5% or 10% delievers results. Use moderately 3 x a week to strat and increase to daily usage once your skin is acclimated and tolerates the treatement. Thank you for your interest in Jan Marini Skin Research products. **Q: WHat is expiration date?** A: My bottle had an expiration date on the bottom. 09/17. **Q: How does age intervention duality work? The active ingredient is benzoyl peroxide and retinol. I thought this combination cancels each other out?** A: No. Retinol helps diminish wrinkles. Benzoyl peroxide helps with acne. It can be drying to skin initially. I would recommend starting every other day. **Q: Is the date on bottom the date the lot was produced or the expiration date? I do not see exp listed on there.** A: On the bottom of mine it says 3/24 so I’m pretty sure that it is the expiration date. Hope that helps. ## Frequently Bought Together - Jan Marini Skin Research Age Intervention Duality - Acne & Anti-Aging Support Face Cream - Clear Skin Support - Beauty & Skincare Product - 1 oz - Jan Marini Skin Research Antioxidant Daily Face Protectant SPF 33 - Hydrating Facial Sunscreen for Daily Use - SPF Moisturizer Sunscreen with Hyaluronic Acid - 2 oz - Jan Marini Skin Research Bioglycolic Face Cleanser - Facial Wash for Oily, Dry & Combo Skin - Personal Face Skincare - Skin Cleanser for Beauty & Personal Care - 8 fl oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/273867778-jan-marini-skin-research-age-intervention-duality-28g-1oz](https://www.desertcart.is/products/273867778-jan-marini-skin-research-age-intervention-duality-28g-1oz) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-09-22*
