While magnesium oil does provide some smoothing to the skin, alpha-hydroxy acids are more effective in reducing wrinkles, reports The Magnesium Perfection. Magnesium oil nourishes the skin, assists in growth and restores color, and it is beneficial for sensitive, dry or oily skin.
Alpha-hydroxy acids reduce wrinkles by gently dissolving the intercellular "glue" that causes old skin cells to stick to the epidermis, resulting in a brighter and finer outermost layer, explains Reader's Digest. The acids also stimulate the production of skin-supporting collagen and elastin. It is also believed that the acids help the skin retain moisture, leaving the skin soft and padded. The downside to using alpha-hydroxy acids, however, is that the skin is left extra-sensitive to the sun, thus increasing the risk of wrinkles if adequate sunscreen is not worn.
