Amlactin is a popular brand of lotion that contains lactic acid as its active ingredient. However, there are several other synonyms for this type of product. One common alternative is urea-containing lotions, which work by softening and loosening dry, hardened skin. Another is alpha hydroxy acid (AHA) lotions, which include not just lactic acid but also glycolic acid and citric acid. These types of lotions can be found under various brand names, but they all work by exfoliating the skin and promoting cell turnover. Salicylic acid lotions are also similar to amlactin, but are geared towards treating acne and other conditions with clogged pores. In general, finding the right skin care product involves considering your individual skin type and needs before settling on a particular brand or ingredient.
