Share
πΏ Why Exfoliating Acids Matter
Our skin naturally sheds dead cells β but stress, dryness, and sun exposure slow that process.
Exfoliating acids keep your skin glowing, smooth, and even-toned by removing the dull layer on the surface.
But not all acids are the same.
πΈ βThe right acid transforms your skin. The wrong one irritates it.β

If your skin looks dull, textured, or tight β AHA gives instant glow.
