If you're using this product (or any spot treatment), it means you've already got a pimple or blemish. So, boo! But—as someone who struggles with occasional adult acne despite a rigorous skincare routine—this is the finest spot treatment product I've yet to find. A very small amount applied to the problem after cleansing and moisturizing (before make-up) twice a day stops the spread and inflammation of pimples almost immediately, and it dramatically reduces the duration of the break-out without irritating sensitive skin. In general, it helps quicken skin cell turnover, helping to fade blemishes and discolorations. Will it miraculously eradicate your pimples? No. Will it make break-outs less irritating as well as easier and more comfortable with make-up? Absolutely!
