How pimple patches work: decades-old wound-care tech adapted for spots
Pimple patches use hydrocolloid technology developed for wound care, absorbing fluid and creating a barrier to stop picking and infection.
Pimple patches are based on hydrocolloid dressings, gel-forming materials developed decades ago for wound care. Dermatologists adapted the technology for acne; it caught on in South Korea almost 20 years ago before reaching Western markets around 2012.
Patches contain a blend of gelatin, pectin and carboxymethylcellulose. When pressed on a pimple, the hydrocolloid absorbs fluid and locks it in.
Some include salicylic acid or tea tree oil. Most cost $6 to $20 a pack.
