What Size Needles Should I Microneedle With? (2025)

Microneedling is a powerful way to improve skin texture, boost collagen, and reduce acne scars, but choosing the right needle length is key to getting the best results. If you're microneedling using a derma stamp , the needle length that is best for you depend on where you're using it and what you're trying to achieve.

Microneedling Needle Size Guide

0.25mm - For Product Absorption & Using around eyes

If you want to enhance your skincare routine or do microneedling around the eye area, a 0.25mm length microneedling head is great for helping serums and treatments penetrate deeper.

0.25mm is safer around the eyes where skin is thinner.

This can be used more frequently around 2-3 times a week with a rest day in between each session.

0.5mm - For Acne Scars and Fine Lines

A 0.5mm needle is ideal if you’re looking to stimulate collagen and reduce the appearance of mild acne scars or signs of aging. This size helps thicken the skin over time and can be used every 2 weeks for best results.

0.5mm is also ideal for hair growth when used together with a hair growth serum.

0.5mm is the best all purpose microneedling length for home use because it can stimulate collagen without the risk of causing further scarring that deeper needles have.

You can use 0.5mm to microneedling the face and neck.

1.0mm - For Deep Scars & Wrinkles , and Stretch Marks

If you have more severe acne scars, dark spots, or deeper wrinkles and stretch marks on the body, a 1.0mm needle is your best option. This length goes deeper into the skin to stimulate new collagen formation. Since it goes deeper it should only be used once a month to give skin to fully recover and build collagen.

1.5-2.0mm - professional use: severe scars, stretch marks

Because of how deep they go, they can help break down and remodel severe scar tissue and stimulate collagen for stretch marks, or severe traumatic scarring.

The deepness of these needle lengths mean that it should strictly be for professional use since it comes with a lot more risks.

Risks of 1.5-2.0mm include:

• infection
• hyperpigmentation
• scarring.

Final Tips for Safe Microneedling

• Always start with clean skin and disinfect your derma stamp before and after use.
• Avoid using needles longer than 1.0mm at home for the face. Anything deeper should be done by a professional.
• Follow up with hydrating, skin-soothing products like the Banish Serum to support healing.

Where can I get a microneedling tool with different size heads?

The Banish Kit 3.0 comes with 0.5mm heads, and you can buy separate sized microneedling heads in 0.25mm and 1.0mm. The great thing with replaceable heads is that it is more affordable compared to buying a whole tool and throwing it out when it needs replacement.

By using the right needle size, tool and technique you can see results for acne scars, fine lines, dark spots and more!
