Age Intervention Duality Anti-Acne/Anti-Aging Cream is a confusing mix, and we can't quite grasp the reason Jan Marini decided to put these two treatments together in a single product.
First, it is important to note that this is a double-barrel container, which means that the benzoyl peroxide treatment (Anti-Acne Cream) is separated from the moisturizer with retinol (Anti-Aging Face Cream). That's good because neither can be formulated in the same product and retain their respective benefits. Let's take a look at each formula individually, and then we will discuss the disadvantages of using them together as the instructions indicate.
This is the less exciting side of the Age Intervention Duality—it's an anti-acne disinfectant medicated with 10% benzoyl peroxide. That's certainly an effective strength to treat stubborn breakouts, but this is as standard as benzoyl peroxide formulas come! You can find options that are more advanced at the drugstore, those that include added irritants to offset the irritation potential of benzoyl peroxide on skin.
Speaking of irritation, it is worth mentioning that 10% benzoyl peroxide doesn't demonstrate an appreciable amount of benefit for treating acne beyond a 5% concentration. However, a 10% benzoyl peroxide is more likely to produce side effects (dryness, flaking, and/or redness), and this one is far overpriced for such a small amount of a standard product.
This is undoubtedly one of the better formulas of Jan Marini's collection. Formulated with a nice array of antioxidants and cell-communicating ingredients (like retinol and peptides) alongside rich moisturizing agents, it's a great pick for those with normal to dry skin not prone to breakouts. Did you catch that last part? Ironically, despite the beauty of this formula, it's not one we'd recommend for the acne prone due to the types of moisturizing ingredients used.
That aside, this anti-aging moisturizer will remain stable thanks to its protective packaging that reduces air exposure, and it's fragrance free. It would be perfect for those with sensitive skin and/or those prone to rosacea, if it weren't for the fact it is paired with 10% benzoyl peroxide treatment. However, like the Anti-Acne Cream, you are only getting a small amount (0.5fl.oz.). The one ounce fill weight is split between both products, making this a pricey moisturizer!
You can find other moisturizers with retinol for less money. However, many of those have formulas that aren't as state-of-the-art as what Marini devised, so it's your call as to whether you want to splurge or simply purchase a separate moisturizer with retinol from those we recommend.
Now, why is the Age Intervention Duality a problematic combination? The first concern is that this is as odd a pairing as we've seen in recent history—the average person in the market for an anti-acne treatment will want to stay far away from the rich moisture of the Anti-Aging Cream side of this duo. The opposite is also true to an extent, as not many people with dry to very dry skin types will appreciate such a potent dose of benzoyl peroxide!
The second concern is that Marini recommends mixing the two products together per use and applying to your face in a single step. Benzoyl peroxide works by oxygenating bacteria, specifically destroying P.acnes (the acne-supporting bacteria) in the process—in effect, you get a short burst of free radicals that means curtains for complexion-spoiling bacteria. Unfortunately, for benzoyl peroxide's free-radical function, antioxidants don't take too kindly to free radicals being in their space. The primary role of antioxidants is to destroy free radicals, and that means mixing benzoyl peroxide with an antioxidant-rich formula like the Anti-Aging Cream results in loss of at least some of the product's anti-acne benefits!
In the end, we have to recommend passing on this combo and consider the alternative anti-acne treatments in the Best Anti-Acne Products and Best Moisturizers section. Bonus: You can easily find alternatives for each separately that will cost you less than the Age Intervention Duality.

Jan Marini Skin Research, Inc., was founded, of course, by Jan Marini, who originally started out marketing products for M.D. Formulations. Thus, it isn't surprising to find that her own line is also aimed at dermatologists, aestheticians, and plastic surgeons, much the way M.D. Formulations is. In direct contrast to many of the other skin-care lines in this niche market, Marini’s line stands out with its selection of far more realistic and varied skin-care products. First, there are no spiraling-out-of-control ingredient lists where everything is thrown in except the kitchen sink. Then, and more important, you will find some well-formulated products that include sunscreens, skin-lightening options, vitamin C products, and good glycolic acid–based alpha hydroxy acid (AHA) products, along with some outstanding retinol options.
It is interesting to observe that Marini attributes the research for her "topical form of lipid (fat) soluble Vitamin C that is stable and able to be absorbed" to the form "developed in conjunction with physician researcher Nicholas Perricone, M.D." Of course, Perricone has his own version of vitamin C products, which are quite similar to Marini's in that they also contain ascorbyl palmitate. That being the case, given that he claims his are the best ever with the highest concentration of the stuff, we wonder if she would now agree with his findings? At least compared to her former partners at M.D. Formulations, Marini's information about vitamin C is more accurately based (it's backed by published research) and there's only a minimal amount of hyperbole. In fact, when it comes to the information Marini and team present to the professionals who retail their products, this line wins high marks for its close-to-accurate information about how skin ages, what can be done to minimize and prevent future signs of aging, and the effects various products have on skin. Of course, you're supposed to believe her products have all the answers, but that's what the reviews below will elucidate.
