There are all sorts of skin-care patches out there — from under-eye gels to acne stickers, anti-aging appliqués and more. One type of skin-care patch that’s been garnering attention from beauty aficionados are microneedling patches. Ahead, we spoke with NYC-based Skincare.com consulting dermatologist Dr. Hadley King and Josie Holmes, Skincare.com consulting esthetician at SKINNEY Medspa about what exactly microneedling patches are and what they are known to do. What Is a Microneedling Patch?Contrary to the name, microneedling patches don’t actually contain needles. Rather, they contain micro-darts in the shape of needles on an adhesive patch. “These self-dissolving micro-darts contain active ingredients that are designed to penetrate the skin’s outermost layers when applied,” says Dr. King. Depending on the ingredients used, micro-darts can help reduce the appearance of acne, acne scars or dull skin. “Once the patches are in place, enzymes in your skin begin breaking down the outer components of the darts so that the active ingredients within it are delivered to the site within your skin,” she adds. Breaking Down Different Types of Microneedling PatchesAccording to Dr. King and Holmes, there are myriads of microneedling patches on the market to address  all kinds of skin concerns. “ZitSticka, for example, fills its patches’ micro-darts with salicylic acid, niacinamide and oligopeptide-76 to treat pimples,” says Dr. King. Others, like Peace Out Wrinkles, contain retinol and vitamin C to help target the appearance of discoloration, dullness and fine lines. “Microneedling patches work on all skin types,” says Holmes. “However, if you do have sensitive skin, you may want to perform a test patch to see how your skin reacts.” How to Use a Microneedling PatchWhile you should always follow the instructions on the label, “you can use most microneedling patches twice weekly,” says Holmes. They are meant to be applied as overnight treatments as needed but not every day. “Don’t leave them on for too long,” adds Dr. King. “The adhesive and occlusive nature of the patch could cause irritation.”It’s also important to apply microneedling patches on a cleansed, dry face. “Most micro-darts are water-soluble, therefore it is important to not get your product wet before application,” she says.
