How To Choose Dr. Pen Microneedling Cartridges for Your Microneedling Treatment

If you're getting serious about your skin with microneedling, choosing the right cartridges is just as important as choosing the right pen. No matter if you're treating acne scars, softening fine lines, shrinking pores, or brightening tired skin, choosing the right option is key to getting real, noticeable results. Dr.Pen microneedling cartridges come in a variety of configurations, each designed for specific skin needs and treatment areas.

But with so many options, how do you know which microneedling pen is best? What pin cartridge should you choose? Can you reuse microneedle cartridges? And how do you match the cartridge with your Dr. Pen microneedling pen, like the M8, A6S, or A7?

This guide breaks down everything you need to know about microneedling cartridges, from different microneedling cartridge sizes and their purposes to how needle length, speed, and safety play a role in optimizing your results.

Different Types of Dr. Pen Cartridges

Dr. Pen provides a variety of options, each with unique pin arrangements for different skin needs. Here's a full breakdown of the options:

• 9/11/12-pin Cartridge: With fewer needles, each one can penetrate deeper into your skin, making these perfect for stubborn issues like deep acne scars, old surgical scars, or stretch marks. If you're dealing with significant scarring on your body - think post-pregnancy marks on your stomach or thighs - these cartridges are your best bet. They're also great for tackling deep wrinkles and cellulite, though they do require a higher pain tolerance.
• 16/18/24-pin Cartridge: They still provide good depth for treating acne scars and age spots, but with slightly more coverage than the smaller pin counts. These work well for anti-aging treatments and are versatile enough to use on different areas of your face and body.
• 36/42-pin Cartridge: They are perfect if you're new to microneedling or have sensitive skin. With more needles spread across the cartridge, each individual needle doesn't go as deep, creating a more comfortable experience. These are excellent for general skin improvement - think brightening dull skin, reducing light acne marks, or softening fine lines around your eyes. If you're looking to fade freckles, improve skin hydration, or work on shallow stretch marks, these cartridges will give you great results with minimal discomfort. They're also perfect for regular maintenance treatments once you've addressed any major skin concerns.
• Round Nano: These are non-invasive cartridges used for nano needling, a treatment that doesn't penetrate the dermis, instead helping your skincare products absorb better. They're perfect for brightening your complexion, reducing dark circles, and keeping your skin hydrated. Think of them as a gentle daily treatment option.
• Silicone Nano: Gentle and surface-level, silicone nano cartridges glide over the skin without breaking it, making them ideal for sensitive areas and infusion-based treatments. Perfect for sensitive zones like under the eyes or for beginners wanting a gentle glow.

Always use the correct cartridge for your pen model to keep it safe and working properly at all times.

Considering Skin Type When Choosing a Cartridge

Choosing the proper cartridge is determined by your skin type and concerns. Some things to keep in mind include:

Fine Lines or Wrinkles

Use either an 11-pin or 16-pin cartridge. These are more gentle on more mature skin, yet stimulate collagen formation.

Acne Scars and Rough Skin

Choose a 16/24-pin cartridge. These penetrate deeper layers of the skin, reducing scarring and improving texture.

Large Pores and Oily Skin

A 36-pin cartridge is an excellent choice. It reduces pore size and balances oil output.

Sensitive or Thin Skin

For sensitive or thin skin, nano cartridges are the best option. They do not fully penetrate the skin, making them ideal for administering serums and strengthening the skin barrier.

Dullness and Dryness

To increase product absorption and brighten the complexion, use a nano or 42-pin cartridge.

Full-Face Treatments

Go for a 16-pin or 42-pin cartridge to cover the full face evenly and effectively.

It's important to remember that microneedling cartridges, including the Dr.Pen M8 microneedling cartridges, are only used once. Even if you are performing treatments at home, do not reuse them. Reusing needles might lead to infection or skin injury. Replace the cartridge after each session for safety and optimal results.

Technical Factors to Consider: Needle Length, Speed, and Safety

When picking the right microneedling cartridge for your Dr. Pen device, it's essential to understand the technical factors that influence treatment outcomes. The most important considerations are needle length, speed settings, general safety, and compatibility with your microneedling pen.

Needle Length

Needle length plays a big role in how deeply the microneedles penetrate the skin. Shorter needles (0.25mm-0.5mm) are commonly used to enhance product absorption, treat fine lines or wrinkles, and improve skin tone.

Medium lengths (0.5mm-1.0mm) are more useful for treating moderate acne scars, stretch marks, and textural issues.

Longer needles (1.5mm-2.5mm) should only be used by professionals for more serious issues, such as surgical scars or significant skin damage.

Adjusting the Speed

Dr. Pen microneedling pens have changeable speed settings. Slower speeds are great for sensitive or delicate areas, such as beneath the eyes, but faster speeds allow for quicker treatments of harder skin zones, such as the cheekbones or forehead. Higher speeds, when paired with suitable depth, can also reduce treatment discomfort while improving precision.

Safety and Compatibility

Check that the cartridge is compatible with your Dr. Pen model. Using the incorrect cartridge may result in poor performance or harm to your device. Make sure to also always use new, sterile cartridges and never reuse needles, even at home.
