Board-certified dermatologists advise against at-home or DIY microneedling (often referred to as derma-rolling) for two reasons. One, there is no clinical evidence that at-home treatments offer any benefits because their limited needle lengths cannot effectively reach the dermis layer. Two DIY methods pose a significant risk of infection since they are not performed in a sterile environment or with sanitized tools. Ultimately, these at-home procedures can lead to more problems than advantages. Conversely, professional microneedling utilizes a safe, FDA-approved device equipped with single-use sterile needle cartridges. When conducted in a clinical setting by experts, these treatments deliver accurate needle penetration and impressive results.
