Hydrocolloids contain gel-forming agents/properties with a flexible adhesive applied to a carrier such as a film to create an absorbent, self-adhesive, waterproof dressing. Apply at night or wear throughout the day to avoid picking. Can be used as a spot treatment applied directly to the location of the pimple. Hydrocolloids work on the acne blemish by creating a protective seal over the skin, while absorbing excess fluid such as oil and pus, flattening spots faster and reducing inflammation/skin redness. Best for someone who has alot of whiteheads (closed comedones).
