Skin Perfecting 2% BHA Gel Exfoliant is a water-based formula that exfoliates both the skin's surface and inside the pore, reshaping the pore lining to unclog pores and improve skin cell turnover rate. This creates a dramatic improvement in the skin's appearance, feel, and function especially for blemish-prone skin. There is a great deal of research indicating that BHA (Beta Hydroxy Acid) increases collagen production and drastically smoothes the surface of skin. Additionally, BHA has anti-bacterial properties that attack blemish-causing bacteria. Benefits: Has a silky base texture. Helps to combat stubborn blemishes. Formula is colorant and fragrance free. Recommended for combination to oily skin types.
