Lactic acid is one of the most popular alpha hydroxy acids available. It is a common ingredient in most over-the-counter skin care products. It is also used in stronger professional peels and treatments. Lactic acid is naturally found in dairy products. It’s what gives yogurt and soured milk that distinctive tang. Dairy products have actually been used by people across the world to soften and beautify the skin!
Lactic acid helps remove old, dull cells on the skin’s surface by dissolving the bonds that hold them together. This process is called exfoliation. Lactic acid speeds up cell turnover and stimulates cell renewal. As a result, it gives you a brighter complexion, as well as smoother and softer skin.
Further, Lactic acid helps to keep the skin moisturized and feeling less dry. When you use lactic acid regularly, it can also improve signs of aging. It does so by stimulating the renewal of collagen, a fiber that helps keep the skin firm. Lactic acid can help fade sun spots or age spots and can smooth and soften fine lines and wrinkles. Lactic acid won’t improve those deeper lines, though.
Lactic acid is also a main ingredient in over-the-counter lotions and creams for keratosis pilaris, or those “chicken skin” bumps on the backs of the arms. Lactic acid helps dissolve the plug of skin cells that build up around the hair follicle, smoothing out the bumpiness. It can also be used as a topical ingredient in the treatment for eczema, psoriasis, and rosacea.
Although there are so many positive benefits to Lactic Acid, you also need to be careful as there are possible side-effects. Lactic acid can make your skin burn more easily in the sun. It can also cause itching and redness. Always use sunscreen when using lactic acid. Also, If you are using any prescription skin care medication, check with your healthcare provider before using any lactic acid treatment. It may not be appropriate for your skin.
To sum, Lactic acid is an alpha hydroxy acid, or AHA, used in over-the-counter skin care products and professional treatments. To simplify things, Lactic acid is used to remove dead skin cells, lighten dark spots, and improve the look of fine lines and wrinkles.
