I did a search and not noticed one instance of a thread on this lotion. It is supposed to be used like a serum and is 20% AHA. Sold through skinstore and dermstore as well as other places.

Has anyone used it?
Supposedly made by a dermatologist...this is it's claim




This remarkable gel-lotion is the ultimate agent for those wanting to get more out of their anti-aging routines. This 20% AHA formulation contains 10% mandelic acid and 10% malic acid with a 2.5 ph. Because of the protective and moisturizing qualities of malic acid, this lotion takes about 10-15 minutes to fully sink into the skin. A bit sticky at first, the MaMa lotion will dry to an ultra smooth, glowing finish that will draw compliments throughout the day. Excellent for evening out pigmentation or softening feet and elbows as well. Because of the potency of the product, it is important to test sensitivity in a small area. Start off using it only once or twice a week.
Remember to wash palms of hands after use in order to prevent peeling.
