Microneedling uses a precision device to create thousands of microscopic channels in the skin. Your body responds by producing new collagen and elastin — the structural proteins that get harder to make as we age. The channels also let topical serums penetrate far more effectively than they ever would on intact skin.
The biggest decision on this page isn't whether to microneedle — it's which topical add-on to use. PRP (platelet-rich plasma) uses your own blood and is the original protocol. Exosomes are regenerative signaling molecules with newer evidence behind them. PDGF (platelet-derived growth factor) is the most concentrated single-factor option. They aren't interchangeable — they have different mechanisms and different price points.
Microneedling is broadly safe across skin tones because it doesn't rely on light or heat to target pigment. We see strong, consistent results in clients across the Fitzpatrick range — something worth knowing if laser hasn't been an option for you.
