Retinol, benzoyl peroxide, green tea extract, peptides, and antioxidants deliver serious acne control and dramatic benefits to aging skin, in one amazing product.

With its dual chamber dispensing system, Jan Marini Age Intervention Duality MD works to deliver two powerful creams to help address signs of aging and adult acne. With Age Intervention Duality MD, you’ll find the same great benefits as Age Intervention Duality in an even more powerful, physician-strength formula. One chamber contains a cream with 10% benzoyl peroxide, plus a blend of anti-inflammatory ingredients, to help address blemishes and irritation at the source. The other chamber dispenses a cream with 1% retinol, antioxidants and peptides to help boost collagen and minimize fine lines and wrinkles. Hyaluronic acid helps to plump, firm and hydrate skin.

How To Use

Cleanse
Start with a gentle, non‑stripping cleanser. Make sure skin is clean, removing all makeup, sunscreen, and impurities.

Prepare product
Shake the bottle well. Leave the plastic lid on, invert the bottle, and tap the top several times into your palm to help prime both chambers. 

Dry skin
Ensure your face (and any treated area) is completely dry before applying. Moist or damp skin can increase irritation, especially with strong actives like benzoyl peroxide + retinol.

Apply cream

  • Dispense 1 pump from each chamber into your palm. 
  • Briefly mix them in your hand. 
  • Apply a thin, even layer over the entire affected area (not just spot treatment). 

Frequency / build‑up

  • Start with once daily in the evening. 
  • If your skin tolerates it (no irritation, peeling, extreme dryness), you may increase to 2–3 times daily as needed and as directed by a physician. 
  • If you get dryness or peeling, reduce to once a day or every other day.

SPF is non‑negotiable
Because this product has both benzoyl peroxide and retinol, it increases photosensitivity. Always apply a broad‑spectrum sunscreen (SPF 30 or higher) during the day. If you’ll be outdoors, use physical protection (hat, shade etc.).
