This is a great question, and the answer is a little more nuanced than simply choosing the “best” pen. As a board-certified dermatologist, I can tell you that while the device matters, the provider’s experience, technique, treatment depth, patient selection, and aftercare often have a greater impact on your results than the specific microneedling pen being used. Here's how I would think about your options: Provider 1: SkinPen SkinPen is one of the most recognized microneedling devices and was the first FDA-cleared microneedling device in the United States. It has strong clinical data supporting its use for acne scars and overall skin rejuvenation. If all other factors were equal, SkinPen has the advantage of extensive research and regulatory backing. That said, excellent results are not guaranteed simply because a provider uses SkinPen. A skilled practitioner using another high-quality device may achieve comparable outcomes. Provider 2: PRX Pen or Cosmo Pen These devices can still produce good results, but they generally do not have the same level of published clinical evidence or name recognition as SkinPen or Dermapen. The quality of the treatment will depend heavily on the provider's expertise and how they perform the procedure. If this provider has extensive experience and a strong portfolio of before-and-after results, the lower price point could make this a very reasonable option. Provider 3: Dermapen with BIO-PRF This option stands out to me. Dermapen is a well-respected microneedling device used worldwide and is widely regarded as comparable to SkinPen in terms of performance. The mention of BIO-PRF and training under Dr. Miron suggests that this provider may have invested significant effort into optimizing the platelet-rich fibrin portion of the treatment. PRF quality can vary depending on how it is processed, and providers who have specialized training in this area may be able to maximize the regenerative benefits of the procedure. How I Would Rank Them If I were choosing based solely on the information provided: Dermapen + BIO-PRF + specialized PRF training SkinPen PRX Pen / Cosmo Pen What Matters Most Before making your decision, I would ask each provider: How many microneedling procedures do you perform each month? Will the treatment be performed by the provider or delegated to staff? What needle depth will be used for my specific concerns? Can I see before-and-after photos of patients with concerns similar to mine? How many sessions do you typically recommend? What is included in the treatment price? In my experience, a highly skilled provider using Dermapen or SkinPen will often produce better results than an inexperienced provider using the most expensive device available. Based on the information you've shared, the Dermapen + BIO-PRF option appears to offer the strongest combination of technology, biologic enhancement, and specialized training while remaining more affordable than the highest-priced option.
