Exuviance is the real deal in the beauty world because of Drs. Van Scott and Yu. If youÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢re unfamiliar with them, they discovered the anti-ageing properties of glycolic acid, leading them to create and patent the first glycolic peel. Since then, their products have provided blueprints for other beauty brands, and the Professional Clarifying Spot Gel is a testament to it. As one of the top acne spot treatments, it treats breakout wounds, deeply cleanses pores, and exfoliates the skin with its potent mix of salicylic acid, alpha-hydroxy acids, and pro-vitamin A.
