Key Ingredients
Benzoyl Peroxide
A powerful antimicrobial agent that effectively kills acne-causing bacteria while providing keratolytic benefits to unclog pores. Clinical studies consistently show significant acne reduction, though it can cause dryness and irritation, requiring careful introduction and proper moisturization.
All-Trans-Retinol
(Vitamin A) The gold standard anti-aging ingredient with extensive clinical research showing benefits for fine lines, wrinkles, hyperpigmentation, and skin texture. Stimulates collagen production and cellular turnover, though requires gradual introduction and consistent sun protection due to increased photosensitivity.
Anti-Aging Peptides
Stimulate the production of collagen, which helps improve skin firmness, elasticity, and reduce wrinkles.
Chrysin
A flavonoid with anti-inflammatory and circulation-improving properties, particularly beneficial for reducing dark under-eye circles. Helps strengthen capillary walls and reduce blood pooling that contributes to dark circles while providing antioxidant protection.
Alpha-Bisabolol
(Bisabolol) A gentle anti-inflammatory compound derived from chamomile that effectively calms sensitive or irritated skin. Clinical studies demonstrate significant anti-inflammatory activity and skin tolerance improvement, making it ideal for sensitive skin formulations.
Green Tea Extract
(Camellia Sinensis Leaf Extract) Rich in polyphenols and catechins that provide antioxidant,anti-inflammatory, and antimicrobial benefits. Clinical studies show photoprotection, acne improvement, and anti-aging benefits, making it one of the most versatile and well-researched botanical ingredients.
NHS
(N-Hydroxysuccinimide) A compound that works synergistically with other ingredients to enhance their efficacy and stability. Provides antioxidant support and helps improve the performance of peptide and other active ingredients in anti-aging formulations.
Hyaluronic Acid
(Sodium Hyaluronate) A glycosaminoglycan that can hold up to 100o times its molecular weight in water, making it exceptionally effective for skin hydration. Naturally present in skin,it helps maintain moisture balance, plumpness, and elasticity while supporting skin barrier function.
Myristoyl Tripeptide-4
A short-chain lipopeptide that enhances skin penetration while targeting specific cellular processes for skin improvement. Designed to support skin structure, firmness, and texture.
Palmitoyl Tetrapeptide-7
Reduces secretion of interleukin-6 (IL-6), decreasing inflammation and preventing collagen degradation. Shown to provide significant improvement in appearance of wrinkle depth, skin density, and elasticity.
Palmitoyl Tripeptide-1
Stimulates collagen and glycosaminoglycan synthesis, promoting skin repair and reducing signs of aging. In a study with 23 women, application led to a statistically significant increase in skin thickness of approximately 4%.
Antioxidants
Help soothe skin and reduce UV and environmental damage, while also offering benefits like brightening, reduced fine lines, calmed inflammation, and improved moisture retention.

how to use Duality™
Collapsible content
Directions
Directions
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 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.
PRO TIP:
• Some redness or flaking is normal as your skin acclimates to this powerful retinol.
• Use just one pump, a little goes a long way!
• Avoid going past the orbital bone to avoid the delicate skin in the eye area.

This duo has cleared up
This duo has cleared up my acne significantly. I have suffered from acne for over 20 years and nothing has helped except these products. I was introduced to Jan Marini during a facial session and was reluctant to try it because I was afraid of being let down again and have overly sensitive skin. However, after the first week of use I noticed a significant difference. My breakouts have decreased dramatically, my pores are clearer, and my skin overall is glowing. These products are expensive but worth every penny and last for up to 4 months, so they are worth it. Highly recommend!!!!!!!

Has transformed my skin
After years of suffering with adult acne, I finally found something that actually works and bonus, helps with aging too. This has a very mild and pleasant smell, is not drying at all and leaves my skin feeling moist looking dewy. I’m a true believer.
