Dryzit® will help dry out pus pimples immediately. The top layer is formulated with Salicylic Acid, Zinc Oxide and Niacinamide which act as an acne peel and help remove debris and dead skin cells, while Calamine, the powder at the bottom of the bottle, reduces irritation and soothes the skin. Trust us, you'll be glad you added this to your acne-fighting kit fast. If the bottle shakes and mixes the contents, simply leave the bottle on a flat surface and wait 24 hours for the ingredients to settle. The effectiveness of the product is not affected. When and how to use it : Use it on pus spots to dry them out quickly. You can apply it to several spots on your skin at once. Dip the cotton swab all the way in so that it can be coated with powder and liquid. Then apply it to the pus spot you want. You can apply it after Zitcontrol® . Do not apply any product to that area afterwards. Do not use it on internal spots that do not have pus, for that we recommend Zitless® .
