Types of Dr. Pen™ Cartridges – Which One Should You Choose for Specific Skin Concerns?

Microneedling is a highly effective way to improve the appearance of the skin, and choosing the right Dr. Pen™ cartridges is essential for achieving the best results. In this guide, we explain the differences between the various cartridge types and help you select the option that best suits your skin’s needs.

Types of Dr. Pen™ Cartridges – Which One Should You Choose?

Each Dr. Pen™ device is compatible with specific cartridge types that differ in needle count and purpose. Below is an overview of the three main categories and the most commonly used configurations.

16-Pin Cartridges – Ideal for the Face and Fine Lines

16-pin cartridges are the best choice if you want to target fine lines, loss of firmness, or overall skin quality. They create precise micro-channels that stimulate collagen production while remaining gentle enough for facial use.

Best for:
✔ Softening fine lines and expression lines
✔ Improving skin elasticity
✔ Firming and smoothing the face

36-Pin Cartridges – For the Body, Scars, and Stretch Marks

If you’re focusing on acne scars, stretch marks, or uneven texture on larger body areas, 36-pin cartridges offer stronger stimulation thanks to the higher needle count. This makes them effective on wider surfaces and for more intensive skin work.

Best for:
✔ Softening the appearance of stretch marks and scars
✔ Smoothing skin texture on the body
✔ Supporting overall skin renewal

Perfect for use with the Dr. Pen A6.

Nano Cartridges – For Delicate Skin and Enhanced Product Absorption

Nano cartridges are the least invasive option. They are ideal if you want a gentle session, improved hydration, or better absorption of serums. These cartridges use microscopic silicone cones that create ultra-fine, invisible channels in the skin, helping active ingredients penetrate more effectively.

Best for:
✔ Boosting skin hydration
✔ Enhancing the effectiveness of serums and skincare formulas
✔ Gentle skin-renewing sessions

Compatible with the Dr. Pen M8 and many other models.
