Pimple patches: hide them or show them off? From Justin Bieber’s mushrooms to Dua Lipa’s stars

Not long ago, a pimple patch was the kind of thing you applied alone in the bathroom, hoping it would quietly do its job overnight before anyone had to know about it. Then Gen Z started wearing them out, celebrities started getting papped in them, and suddenly they were a thing. Which brings us to April, when Justin Bieber designed a mushroom-shaped one for his wife Hailey’s skincare brand Rhode, timed to his Coachella headline slot. He sold the patches at a festival activation in the desert – which probably says more about where the beauty category stands in 2026 than anything else. The material inside every pimple patch, hydrocolloid, has been around since the 1960s, and was originally used in dressings for superficial open wounds. The technology was commercialised in the 80s, and dermatologists soon began using it on facial dermatitis and acne. By the 2010s, over-the-counter pimple patches had become common. Korean skincare brand CosRx’s Acne Pimple Master Patch was an early template: thin, translucent and effective, and built on the premise that you’d never know it was there. “The term hydrocolloid refers to materials that retain moisture,” explains Dr Amy Bandy, a California-based plastic and reconstructive surgeon with her own practice. Pressing a patch onto a surfaced blemish triggers the material to draw fluid and debris up from the pore. “The patch creates a closed environment at the site of the skin lesion, protecting it from friction and contact with bacteria,” she adds. Dr Olga Bachilo, a plastic surgeon and the founder of Texas-based Glamour Plastic Surgery and Med Spa, says the colour change in pimple patches is the most misunderstood part of the process. “The white colour that people see after sleeping in a patch is the hydrocolloid gel swelling with fluid absorbed into it. It is not clinically related to the removal of pus,” she explains. If the patch stays clear, there was probably not a lot of fluid on the surface to begin with, she adds. Pimple patches are also great for the physical barrier they provide. Covering a blemish is one of the more reliable ways to stop yourself from picking at it, which is where a lot of acne scarring actually comes from. “It has been shown that hydrocolloid patches decrease manipulation of lesions, accelerate healing times and prevent irritation caused by constant picking,” Bandy notes. That alone may make the case for them, even on days when there’s no white patch to show for it. Patches only really work, however, on pimples that have something to draw out. A whitehead, a popped zit, anything surfaced – totally. A deep cystic blemish sitting under the skin with no visible head – not so much. “Cystic acne occurs deep in the dermis, and a patch on top of it does not get at the root of the problem,” says Bachilo. “Those who suffer from hormonal or cystic acne require a completely different clinical approach.” Bandy agrees: “It would appear that hydrocolloid patches are incapable of reducing inflammation originating at that point,” she says, though she notes there may be some slight reduction in symptoms. Hero Cosmetics co-founder Ju Rhyu brought the format properly to the US in 2017, after years working in South Korea – where wearing patches in public had become normalised by the early 2010s. Launched on Amazon, the Mighty Patch was designed to be translucent and discreet, which turned out to be exactly right for a broader audience. Then New York-based Starface entered the chat and made the case for the opposite approach. Launched in 2019 by former Elle beauty editor Julie Schott and entrepreneur Brian Bordainick, the brand argued that the acne category had been built on shame – and there was another way. Starface’s Hydro-Stars are bright yellow, star-shaped and meant to be seen. Bit by bit, that idea caught on. Justin Bieber wore them on the street, Dua Lipa and Florence Pugh were spotted in them, Bella Hadid and Anne Hathaway made them feel almost like an accessory – and suddenly, the visible pimple patch had become its own genre. Since then, the category has continued evolving. Medicated patches, for example, fold active ingredients like salicylic acid, niacinamide and tea tree into the hydrocolloid, giving the patch something to do beyond absorbing. While the hydrocolloid handles the fluid, the actives work on what’s happening around the blemish, whether that’s excess oil, inflammation or bacteria – which can make a real difference for reactive skin, even if the treatment remains surface-level. But for those dealing with blemishes that haven’t surfaced yet, even a medicated patch has its limits – and that’s where microneedle patches come in. Instead of sitting on top of the skin, these use hundreds of tiny self-dissolving tips to carry ingredients slightly below the skin barrier. “Microneedling attempts to penetrate through part of the [skin’s outermost layer],” Bandy explains. “Small channels can then allow for the delivery of various active ingredients – such as salicylic acid, niacinamide and hyaluronic acid – more effectively than traditional hydrocolloid surface applications.” However, she notes, the penetration depth of these patches can still be quite limited compared to prescription therapies or treatments. Knowing which patch to reach for is only half the battle: how you use it matters just as much, and this is where most people go wrong. Applying to clean, completely dry skin is a non-negotiable. Otherwise, “the hydrocolloid absorbs sunscreen or make-up residue on the skin rather than the contents of the blemish itself”, Bachilo warns, estimating that roughly eight in 10 patients who come in frustrated with patches have made this mistake. Patch size matters too: if the adhesive doesn’t fully cover the blemish, it won’t work properly at the edges. Meanwhile, applying a standard hydrocolloid patch to a deep, painful cyst with no head – and then wondering why nothing happened overnight – is the surest way to feel let down by something that was never designed to reach that far below the surface. What’s interesting is that the pimple patch hasn’t actually changed much since its wound-care origins. It’s been upgraded, for sure, but the real revolution has been in how we think about and present acne – and that turned out to be a much harder thing to shift.
