What Are Acne Patches ?
It turns out the technology used in acne patches isn’t new.
“They’re something called hydrocolloid dressings which we’ve used in dermatology and surgery for decades,” says dermatologist Nikhil Dhingra, MD, of Spring Street Dermatology.
“Hydrocolloid is a unique material that’s able to absorb extra moisture without drying the skin.”
The moisture-sucking ability has made hydrocolloid dressings essential in wound healing by not only absorbing excess moisture that could slow down the healing process, but also protecting the wound from outside infection. Before acne patches came to exist, you probably saw this same technology in those blister pads you stuck on your heels after a long hike.
