Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant is a powerful but lightweight exfoliator designed to renew the skin, reduce the size and appearance of pores and banish dead skin cells for a brighter, more radiant complexion. With its unique blend of skin-loving ingredients, it works with the skin to get deep beneath the layers to unclog pores and give a smoother, more even tone without causing irritation. Left on overnight, the lightweight liquid absorbs quickly into the skin to target impurities on the surface and deep beneath the outer layers, reducing redness and inflammation whilst giving a deep exfoliation to tired, lifeless skin. This exfoliator is packed with a secret ingredient: salicylic acid - an antioxidant-rich ingredient that increases collagen production and stimulates tighter, firmer and more youthful-looking complexion. The acid also reduces the appearance of wrinkles, leaving skin firmer to the touch and looking healthier and more radiant. Non-irritating and always fragrance-free, pores are shaped and reduced in size, leaving the skin looking renewed, vibrant and more even in tone.
