When it comes to microneedling, not all treatments are created equal. At-home devices won’t provide the same effects as an in-office treatment from a board-certified dermatologist.
Microneedling involves puncturing the skin with thin needles to create tiny wounds, triggering the skin’s repair mechanisms and stimulating collagen production. According to Dr. Alster, this treatment can improve the appearance of large pores, fine lines and wrinkles, scars, and stretch marks.
To achieve these results, Dr. Alster says, doctors use sterile needles that puncture deep enough to cause bleeding. On the other hand, she says, roller devices used for microneedling in the home or at nonmedical spas have shorter, duller needles. These devices are not meant to penetrate the skin, she says, so while they may stimulate blood flow to create a temporary brightening effect, they can’t deliver the same results as a microneedling treatment from a doctor.
