Skin patches used to be just for treating simple whiteheads. But thanks to new technology, the latest crop of skin-perfecting stickers promises to banish dark spots, erase wrinkles and even flatten hard-to-treat cystic acne. Here, four patches worth popping on.

Smooth operator

Designed to fade lingering post-pimple redness and other hyperpigmentation, these patches use microscopic pinpricks to deliver a potent cocktail of skin-brightening ingredients, including tranexamic acid, a skin lightener. The dainty dots are designed to be worn overnight or for a minimum of six hours.

This stick-on, two-step system decimates deep, early-stage zits — the kind of pimples you feel long before they erupt. First, an enclosed cleansing pad preps the targeted spot, then the prickly patch gets straight to the root of the problem with a medicating dose of salicylic acid, niacinamide and hyaluronic acid.

Skin-care star

Pimple patch, but make it fashion. Show your face during a bad breakout by covering up with a cutesy star-shaped sticker. Created by a former beauty editor, these hydrocolloid patches draw out pus and prevent absent-minded picking throughout the day.

Packed with hyaluronic acid, vitamin A and peptides, these patches send wrinkle-banishing ingredients under the skin. Because the signs of aging are so stubborn, they’re designed to be worn for two hours a day, every other day, with results appearing within two weeks.
