C-ESTA Cream contains a good amount of vitamin C in the form of ascorbyl palmitate, but the jar packaging won’t keep this light- and air-sensitive ingredient stable during use, and there isn’t much else to extol about this product.
All plant extracts, vitamins, antioxidants, and other state-of-the-art ingredients break down in the presence of air, so once a jar is opened and lets the air in these important ingredients begin to deteriorate. Jars also are unsanitary because you’re dipping your fingers into them with each use, adding bacteria which further deteriorate the beneficial ingredients.
Even in better packaging, this moisturizer contains some problematic plant extracts as well as the controversial ingredient DMAE (listed as dimethyl MEA). Please see our Cosmetic Ingredient Dictionary for details on this ingredient. Needless to say, your skin deserves more than what this can provide.

Jan Marini Skin Research, Inc. At-A-Glance
Strengths: Most of the products are fragrance- and colorant-free; excellent AHA and retinol options, including an AHA combined with sunscreen; the water-soluble cleansers.
Weaknesses: Expensive; some categories contain ingredients (growth factors, hormones, and interferon) with unreliable track records or whose long-term risks, if any, remain unknown; sunscreens that lack sufficient UVA-protecting ingredients; jar packaging; Marini Lash isn't as exciting as Marini’s former lash-enhancing products.
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.
