How Do Pimple Patches Work? Here’s Everything You Need to Know

How do pimple patches work? Back in the day, getting a zit meant caking on disguising layers of foundation, concealer, powder …or maybe just a strategically angled hairstyle. But now, the game has changed: Why hide a pimple when you can dress it up? No frantic blending or pore-clogging products are required. Today, we’re embracing a radically different (and refreshingly low-key) approach to clogged pores: slapping a bright yellow star-shaped sticker on it and calling it a day.

Welcome to the era of the pimple patch, where blemishes aren’t shameful secrets to conceal but just part of the human experience. While putting a literal sticker on a zit may seem bold, it’s also an effective way to treat blemishes. Here, we dive into the science, benefits, and best ways to rock a hydrocolloid pimple patch.

What Is a Pimple Patch?

In simplest terms, pimple patches are tiny, adhesive stickers made to tackle different types of acne, one blemish at a time. These patches unclog pores and absorb excess fluid, speed up wound healing, and keep you from picking at your skin—no small feat. Pimple patches come in various formulas, with different ingredients for different breakouts, but the most popular are hydrocolloid acne patches.

Hydrocolloid patches are a type of wound dressing that helps retain moisture and create a moist, healing environment for pimples, burns, or lesions. “They’re made of a water-attracting material, which is attached to a really thin plastic film,” says cosmetic chemist Michelle Wong. “So if you have an open pimple, for example, it can suck out the pus.”

Although hydrocolloid dressings has been used for wound care since the 1960s (the dressings were originally developed in the 1930s by a dentist), it wasn’t until the early 2010s that pimple patches started showing up on skincare and beauty shelves.

When applied to an inflamed pimple—typically one with fluid—the warmth of your skin softens the lining of the sticker, helping it suck out the impurities and gunk. It also acts as a protective barrier that shields the blemish from further irritation or spread. If you’ve ever pulled off a patch to find the underside coated in an icky white substance, that’s a mix of the hydrocolloid gel and the excess oils pulled from the skin. This healing process also prevents you from picking at the pimple—a habit that can lead to longer healing times, infection, and scarring.

Other Spot Treatments

“Spot treatments [tend] to contain benzoyl peroxide, salicylic acid, or witch hazel,” writes Lindsey Zubritsky, a board-certified dermatologist at Premier Dermatology and Skin Cancer Center, in an email. “These are active ingredients—while they may work, they can also potentially cause dryness and irritation.” Pure hydrocolloid patches, on the other hand, don’t contain active ingredients, which makes them ideal for sensitive or reactive skin types.

How Often Can You Use Hydrocolloid Patches?

According to most dermatologists, you can use pimple patches as needed. Zubritsky (aka @dermguru on TikTok) suggests wearing them for up to 12 hours, ideally overnight. But they can also be worn during the day. They’re particularly effective on fluid-filled pimples, such as papules, pustules, or cysts.
