What a wonderful discovery! This liquid solution, presented in a small bottle with a roll-on applicator is the best cure for blemishes, pimples and other unpredictable skin imperfections I have ever tried. The size is really handy (more or less the standard measurements of a lipstick), so you can keep it in your purse and use it whenever you feel a new pimple is coming out. I bought it on sale for an extremely convenient price (5€), but even without promotions Sephora's line products are usually not expensive.
The formula is very antiseptic, so it soothes the skin and dries the imperfections almost immediately (you can feel it itching the second you put it on - it means it's already working).
Unlike other products with the similar purpose, not only has no color, but, best of all, does not peel off makeup, so it can be applied over your foundation. The only counterpart is its rather strong and alcoholic scent, but that's not a big issue. It became a loyal ally and one of my best purchases ever.
