We simply adore naturally occurring acids that we use in our products! :-) We could not live without them. They come from nature, we consume them every day (in dairy products, juices, fruits, homey and wine) so they probably will not make us allergic. They are good for every skin regardless of age or skin type. They work miracles when it comes to cleansing your skin. They rejuvenate and moisturize. You will love them, too!
