How Do Acne Patches Work ?
Remember learning about osmosis in elementary school science class? It’s the idea that water is drawn to a place that has more particle density.
“That’s the principle of these patches,” says dermatologist Morgan Rabach, MD of LM Medical. “The patch is filled with very dense material so it actually pulls water and moisture out of the skin so balance is restored.”
In acne terms, this doesn’t just mean water. These patches attack acne by drawing out excess oil, puss, and other wet substances that are caught deep inside the pore and cause the pimple to form. Dr. Rabach is quick to note that because of this moisture-drawing ability, acne patches tend to work better on pimples that have already reached the surface, like whiteheads or zits that have already ruptured, instead of deep cystic zits below the surface. “There has to be some connection to the fluid in the patch otherwise there is no way for the patch to access what’s inside,” she says.
An added benefit of the patches, according to Dr. Dhingra, is that they also act as a bandage to protect the zit from additional infection once it’s actually popped. “It creates a clean and protected environment sort of like a Band-Aid,” he says. By protecting the zit, it can help cut down on the risk of it leaving a scar or dark mark on your face.
