When using a Dr. Pen microneedling device, choosing the right cartridge and depth is crucial for achieving the best results for your skin. Here's a simple guide to help you select the right needle based on your skin concern. Keep in mind that for serious issues, it’s always best to consult a doctor or skincare professional.

General Guidelines
Your choice of pin and depth depends on the area you're treating and the specific issue you're addressing:
- Nano needles: For superficial treatments, painless and ideal for serum absorption, general skin rejuvenation and daily care.
- Fewer pins (9-18): More targeted, deeper treatments for scars and stretch marks, but potentially more painful.
- More pins (24-42): Good for larger areas like the neck or thighs, suitable for improving general skin texture and skin tone.
