If you're new to microneedling, also known as collagen induction therapy, the process, which involves taking little needles to your face (and lips), can seem daunting. "[Microneedling] can be used to improve skin texture, acne scarring, and wrinkles,” says Shari Marchbein, dermatologist and clinical assistant professor of dermatology at New York University School of Medicine. While it's been said that using a dermaroller to your lips can help increase the size (i.e. plump 'em up), Marchbein says most professionals prefer injections to microneedling. "[For fuller lips], dermatologists prefer lip augmentation using fillers especially those made of hyaluronic acid," she says, as microneedling does not provide immediate results like fillers would.
