When cold, dry air arrives, you may notice that your Skin suddenly appears duller or is more prone to breakouts. A common culprit is the accumulation of dead, pore-clogging Skin cells on the surface of Skin. For this reason, autumn and winter are especially important seasons to exfoliate your Skin, getting rid of this debris so your Skin can stay clear and look radiant. Skincare treatments that contain alpha hydroxy acids (AHAs) will help with this. Derived from fruit and milk, AHAs slough away dead Skin while stimulating the production of collagen and elastin beneath the surface of Skin.
