Drunk Elephant has two T.L.C. products: the T.L.C. Framboos Glycolic Resurfacing Night Serum and the T.L.C. Sukari Babyfacial 25% AHA + 2% BHA Mask. The mask is very potent, and should be used no more frequently than one time per week. For the serum, most people will do best using it every other night or two times per week. Since it has a higher percentage of exfoliants in the formula, using it too often may irritate the skin and damage the skin barrier.
