Hydrocolloid Best Absorbent Anti-Blemish Hydrocolloid at a glance Type of adhesive wound dressing Comprised of polymers for a gel-like texture Helps absorb exudates from wounds Effective in improving the look of whiteheads Hydrocolloid description Hydrocolloid is a word that refers not to a single ingredient, but a particular type of adhesive wound dressing made up of polymer-based materials. The texture of these dressings is different from traditional fiber-like bandages in that they have a bouncy, almost gel feel. The purpose of hydrocolloid bandages is to absorb exudates (cells and fluid that seep from an open wound), hold them away from skin, and provide a protective barrier while a skin injury heals. Used for several decades in medical settings, these bandages are now popular in over-the-counter form, especially for acne breakouts. Studies indicate that hydrocolloid bandages or patches can indeed be effective, especially on whiteheads (AKA classic acne pimples or closed comedones). Research shows hydrocolloid bandages can help improve swelling and decrease the duration of pimples by helping to draw out the material within. As a result of this, they also help relieve the discomfort that comes with some types of breakouts. An additional benefit is that by covering a zit with a protective barrier, it is shielded against additional external bacteria and UV radiation, which negatively impacts healing. This makes hydrocolloid bandages or patches a good option, especially when trying to get rid of a pimple fast. Another benefit: covering a pimple with a hydrocolloid patch discourages picking, thus reducing the potential for a breakout to become a scar. We should point out that hydrocolloid patches, while helpful, are best for occasional noticeable breakouts and are just one part of a well-rounded skin care routine that includes gentle, irritant and fragrance-free products with effective ingredients proven to fight acne.
