In terms of the SkinCeuticals hydroxy acid treatments, how often should you use them for best results?
The Intense Line Defense should be used at night only – it acts as a mild exfoliator but is also particularly good for acne prone skin. The Clarifying Clay Masque should be used between 3 and 4 times a week. In the case of cleansers and toners, these are used daily, both morning and evening. They contain 1% mixed hydroxy acids (malic lactic tartaric citric and glycolic).
