Episode notes
How Microneedling Stimulates Natural Repair
- Microneedling creates controlled micro-injuries that trigger the skin's natural wound-healing and collagen production processes.
- Repeating millions of tiny holes remodels scar tissue and stimulates new, functional collagen without linear scarring.
Needles Vs Heat: Different Tradeoffs
- Lasers and peels use heat or ablation to target chromophores and can treat specific problems but carry higher complication risks.
- Microneedling avoids heat, lowers risk across skin types, and can create far more micro-injury points than lasers for scar remodeling.
Why RF Needling Isn't True Microneedling
- Radiofrequency 'microneedling' is misleading because it uses needles only to deliver heat, not to create classic microneedling effects.
- RF heating is non-selective like microwaves and often yields poor-quality collagen and surgical complications later.
