The Bio Pen Q2 is a powerful microneedling device that combines needle therapy, EMS microcurrent, and LED light treatment, but with multiple cartridge options, it can be confusing to know which one is right for your skin goals.
Here’s a simple breakdown to help you choose the best pin for your needs:
9-Pin – Precision for Small Areas
Use on: Under eyes, lips, nose sides, and targeted spots
Best for: Fine lines, puffiness, sun spots, and acne scars
➤ Ideal for delicate, hard-to-reach areas where precision matters most
14-Pin – Balanced for Face & Scalp
Use on: Full face and scalp
Best for: Wrinkles, pigmentation, acne scars, and hair growth
➤ A well-rounded option for full-face rejuvenation and scalp treatments
25-Pin – For Larger Areas & Body
Use on: Cheeks, forehead, jawline, neck, thighs, belly
Best for: Stretch marks, surgical scars, and overall skin texture
➤ Covers more area with fewer passes — perfect for body and stubborn concerns
Nano – Non-Invasive Infusion
Use on: Face (all skin types, even sensitive)
Best for: Boosting serum absorption, hydration, and daily glow
➤ No puncture, no downtime — great for beginners and in-between treatments
Needle Depth: Up to 1.5mm — Why It’s Still Effective
The Q2 Microneedling Pen features adjustable needle depth up to 1.5mm, which is slightly shorter than traditional microneedling pens that can go up to 2.5mm. But here’s why that’s actually a benefit:
- The Q2 combines EMS (microcurrent) technology, which enhances product penetration and stimulates skin at a deeper level, even without deeper needle insertion.
- The shallower depth means less trauma to the skin, resulting in shorter recovery time and less redness or irritation after treatment.
- You still get visible results in collagen production, skin firmness, and product absorption with a more comfortable experience.
So even though the needle doesn’t go as deep, the combination of microneedling + EMS gives you powerful, skin-transforming results.
