Joel Marshall: Microneedling, Exosomes & Why RF Isn’t Really Microneedling

What if the best way to rejuvenate your skin isn’t lasers, peels, or expensive devices, but teaching your skin to repair itself?

In this episode, Joel Marshall, Founder and CEO of Dp Derm joins us to reveal how modern microneedling has evolved from rollers and stamps into the precision of the Dermapen 4. We explain how controlled micro-injuries stimulate natural collagen production, break down scar tissue, and restore youthful function without the risks of heat-based treatments. He also shares why so-called radiofrequency microneedling is misleading and potentially harmful.

We also explore the role of exosomes, NAD⁺, vitamin C, and licorice root extract in amplifying results, along with why pre-treatment preparation and post-care are essential for long-term outcomes. Joel’s mission is clear: make skin health accessible and effective through science-driven protocols, not marketing gimmicks.

Joel Marshall is the Founder and CEO of Dp Derm, the US home of DermapenWorld, and a global leader in professional microneedling technology. He has pioneered safer, smarter, and more effective approaches to skin rejuvenation.
