Works for acne blemishes and blackhead. Active break out warrior! If you have oily skin, this is a must have. It lasts forever! There are directions on how to use it, but I just sprinkle a little bit into my hand with some water. It doesn’t take very much. It’s a very, very thin layered product once applied. Leave on 15-20 min for normal skin. 5-10 for sensitive. Can be used for so many things! LTKBeauty LTKGiftGuide LTKU
