I've been a fan of clay masks for years now, loving the natural ingredient and the tightening effect they have on my oily skin. I've tried several brands, including the self-made version my mom makes in her kitchen (she doesn't trust beauty experts and have been mixing her won beauty products for years). Clay is a natural powder that is extremely rich in mineral salts and trace elements; it consists of very fine particles of matter that result from the breakdown of silicate rock by erosion or thermal variations. I was excited to hear Lierac Paris, the brand I fell in love with after trying their essential oil last year, is launching four new products based on clay. Here is what you can find in the SkinFitness Centers at select Duane Reade locations:

Gentle exfoliator- Exfoliating cream scrub softens and soothes skin with white clay. The formula is enriched with soothing mallow extract, detoxifying linseed flower extract and exfoliating particles and massage beads. Its vaporous rice notes delicately powdered with white musk and peony soothe the skin. Ideal for all skin types.

Purifying mask- Absorbing and purifying green clay delivers an instant sensation of purity to combination and oily skin. It helps mattify the skin and tighten the appearance of pores. Its formula is enriched with astringent lime, anti-bacterial and anti-inflammatory star anise extract and absorbent kaolin. This lightweight cream combines jasmine bouquet with fresh green notes.

Comfort mask- Skin-softening and moisturizing pink clay and rose extract deliver an instant sensation of comfort to skin. The formula is enriched with antioxidant and nourishing cherry flower extracts, shea butter and mango and apricot oils deliver extra comfort. Infused with sensuous scents of rose, magnolia and ylang-ylang. Ideal for all skin types.

Radiance mask- Detoxifying and toning yellow clay delivers an instant radiance boost to skin. Its formula is enriched with hydrating and anti-wrinkle poppy extract, energizing, detoxifying and radiance-revealing blood orange extract and skin smoothing wheat proteins. This slightly pearly orange-tinted gel-cream texture delivers fresh citrus notes.

Can't wait to try the purifying mask!
