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.

“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.

Speech-to-text capability is now baked into all modern computers. But what if you didn’t have to dictate to your computer? What if you could type just by thinking?

Silicon Valley startup Sabi is emerging from stealth with that goal. The company is developing a brain wearable that decodes a person’s internal speech into words on a computer screen. CEO Rahul Chhabra says its first product, a brain-reading beanie, will be available by the end of the year. The company is also designing a baseball cap version.

The technology is known as a brain-computer interface, or BCI, a device that provides a direct communication pathway between the brain and an external device. While many companies such as Elon Musk’s Neuralink are developing surgically implanted BCIs for people with severe motor disabilities, Sabi’s device could allow anyone to become a cyborg.

It’s not exactly Musk’s vision of the future, which involves implanted brain chips to allow humans to merge with AI. But venture capitalist Vinod Khosla, who was an early investor in OpenAI, says a noninvasive, wearable device is the only path to getting lots of people to use BCI technology.

“The biggest and baddest application of BCI is if you can talk to your computer by thinking about it,” says Khosla, founder of Khosla Ventures, one of Sabi’s investors. “If you’re going to have a billion people use BCI for access to their computers every day, it can’t be invasive.”

Sabi’s brain-reading hat relies on EEG, or electroencephalography, which uses metal disks placed on the scalp to record the brain’s electrical activity. Decoding imagined speech from EEG is already possible, but it’s currently limited to small sets of words or commands rather than continuous, natural speech.

The drawback of a wearable system is that the sensors have to listen to the brain through a layer of skin and bone, which dampens neural signals. Surgically implanted devices pick up much stronger signals because they sit so close to neurons. Sabi thinks the way to boost accuracy with a wearable is by massively scaling up the number of sensors in its device. Most EEG devices have a dozen to a few hundred sensors. Sabi’s cap will have anywhere from 70,000 to 100,000 miniature sensors.

“Given that high-density sensing, it pinpoints exactly what and where neural activity is happening. We use that information to get much more reliable data to decode what a person is thinking,” Chhabra says.

The company is aiming for an initial typing speed of 30 or so words per minute. That’s slower than most people type, but he says the speed will improve as users spend more time with the cap.

Val Kilmer AI deepfake film As Deep as the Grave has just released its first trailer. The internet has responded with overwhelming disgust.

A widely recognised actor known for his roles in films such as Top Gun, Batman Forever, and Kiss Kiss Bang Bang, Kilmer died from pneumonia last April at 65 years old. Upcoming film As Deep as the Grave has now used generative AI to create a digital puppet in Kilmer’s likeness, having it portray a character appearing in “a significant part” of the historical film.

As Deep as the Grave follows married archaeologists Ann Axtell Morris (Abigail Lawrie) and Earl H. Morris (Tom Felton), who conducted fieldwork in the U.S. southwest during the 1920s. Kilmer’s AI-generated likeness will be used to depict Father Fintan, a Catholic priest who is also a Native American spiritualist. The film also features Abigail Breslin, Wes Studi, and Finn Jones.

Though Kilmer was cast in As Deep as the Grave prior to his death, delays in production and issues with his health meant he never shot any scenes. Kilmer had previously given a tech-assisted performance in Top Gun: Maverick, which digitally altered his real voice. He also worked with UK company Sonantic to create an AI speaking voice based on his old recordings. However, As Deep as the Grave will be the first time his likeness and voice will be completely AI-generated in a film.

“Very fitting that this trailer includes a scene where a corpse is unceremoniously yanked out of the ground,” read one of the top comments on As Deep as the Grave‘s trailer at time of writing.

CGI likenesses of deceased actors have been used in feature films before. In 2016, Rogue One: A Star Wars Story gained attention for using CGI and motion capture to resurrect Peter Cushing and portray a younger Carrie Fisher for a few minutes of the film. In 2015, Furious 7 used similar techniques to insert Paul Walker into the remainder of the film after he died mid-shoot. Though Furious 7 largely received a pass due to the circumstances, Rogue One received criticism regarding the ethics of its CGI Cushing. Using generative AI to completely create a performance out of nothing appears to go a step even further, completely removing any actors from the process.

Writer and director Coerte Voorhees told Variety that he chose to use AI rather than recast the role due to budget constraints, and that Kilmer’s children gave the project their blessing. Even so, online commenters have labelled it disgusting and disrespectful, not only for digitally reanimating Kilmer but also for the damaging precedent As Deep as the Grave‘s use of AI could set for the film industry as a whole.
