Serious acne control and dramatic benefits for aging skin, in one amazing product. Its unique dual chamber dispensing solution combines some of the most proven, yet previously incompatible, technologies in one product. The maximum allowed percentage of ultra-micronized benzoyl peroxide, highly concentrated all-trans-retinol, green tea extract, anti-aging peptides, advanced hydrators, and antioxidants deliver unparalleled results in an easy-to-use solution. Jan Marini Age Intervention Duality addresses even the most stubborn adult acne while simultaneously minimizing the appearance of fine lines and wrinkles.

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

Independent Study Results:

A 3-month independent physician study using the Skin Care Management System™ and Duality MD™ on 21 subjects ages 20-29. Conducted by Jaggi Rao, MD Board Certified Dermatologist, FRCPC, Professor of Medicine, University of Alberta.

Subject Assessment Results:

100% of subjects experienced a reduction in acne lesion counts.
Improvement was statistically significant by week 4 and continued to improve through completion.
64% average lesion count reduction (range 36% to 78%).
100% of subjects experienced significant improvement in skin quality by blinded photographic review.
High subject satisfaction with no reported irritation or excessive drying.

How to use:

Shake well before use. Prior to use, leave plastic lid in place, invert and tap the top of the container several times into the palm of your hand. If you experience difficulty when dispensing, repeat and pump product into the hand while inverted.

Clean the skin thoroughly before applying this retinol benzoyl peroxide product. This product contains two parts. Dispense and briefly mix together one pump of product from each of the two chambers on your palm. Cover the entire affected area (not a spot treatment) with a thin layer of this acne control cream one to three times daily. Because excessive drying of the skin may occur, start with one application daily, then gradually increase to two or three times daily if needed or as directed by a physician. If bothersome dryness or peeling occurs, reduce the application of Jan Marini's Age Intervention Duality to once a day or every other day. If going outside, apply sunscreen after using this product. If irritation or sensitivity develops, stop the use of both products and ask a physician.

Please note: Benzoyl Peroxide may bleach clothing.
