Best Derma Roller Size for Acne Scars

My focus on this article will be on best derma roller size for acne scars. You will find out what size should be used on a specific acne scarring type.

You probably know a little about derma rolling for acne scars and its benefits; and if you need more information about how to use dermaroller for acne scars, please read this.

But before we start, let me summarize the top benefits of derma rolling & why so many people are obsessed with it!

Here’s why:

    • Helps to reduce appearance of acne scarring from mild to severe cases.
    • Targets all signs of aging from fine lines, wrinkles, crows feet, and loose/saggy skin.
    • Reduce skin discolorations and hyperpigmentation and gives you a more toned and brighter skin appearance
    • Helps with hair loss or scalp problems and for those who wishes to have healthier hair growths or grow their beards
    • Helps in lightening up your stretch marks or reduce cellulite that have been brought about by pregnancy or when you lose weight from obesity


Now that you get to know the top benefits, I’ll be discussing the different derma roller size for acne scars and how they can be suitable for different types of acne scarring.  

What are these acne scars anyway?

Basically, these are the types of acne scars that derma rolling can heal and repair:

  1. Icepick Scarsnarrow, small, and sharp pitted shape scars caused by cysts and papules that occurred very deep on your skin pores
  2. Boxed Scars- indents in the skin with sharp edges that are usually bigger than the original size of the acne lesion
  3. Rolling Scars- acne scars that are soft and with smooth edges, and unnoticeable when you try to stretch your skin


This is probably the question that’s on your mind: What size dermaroller for acne scars?

Derma rollers come in various sizes or needle depths.

The short needles are those that range from 0.2mm up to 0.5mm. The longer ones are those from 1.0mm to 2.0mm.

For at-home treatment, sizes from 0.2mm up to 1.0mm are safe to be used.

Anything beyond it, like the size 1.5mm and 2.0mm are not suitable for non-professionals. Only the trained professionals can administer the use of it in a registered skin clinic.

Let me enumerate each one so you can see clearly and understand more what, when, and how to use the best derma roller size for acne scars.

0.2 - 0.3 mm Dermaroller for Acne Scars

These microneedles are the smallest of all the derma roller sizes.

They are not intended for treating acne scars because it cannot stimulate the production of collagen.

However, it is best for what is called as “Transdermal Absorption”. 

This means, it will enhance the absorption of your skincare products because it creates a lot of micro channels after rolling so the topical products that you apply can penetrate into the deeper layers of the skin. This makes the product more effective!



Other benefits:

  • If you want to give your skin some facial boost, you can use this type of derma rollers.
  • Can be incorporated as part of your night regimen to make the skincare products more potent
  • Can be safely used in the sensitive area like near the eyes , neck, or temples



  • If you have problematic skin, it will take some time before you see dramatic results
  • It CANNOT treat acne scars
  • It is only used for treating very mild cases of skin imperfections like dull skin.
  • If you are the type who is not consistent to keeping a skincare routine, you will not see quick results when using this dermaroller.


How painful is this needle size?

  • In terms of pain, I would rate is as 0! (10 being the highest).
  • You will not feel any sting at all (as long as you don’t roll it hardly)!


How often to use?

  • It can be used for up to 2-3 times a week to maintain a healthy, radiant glow.

0.5 mm Dermaroller for Acne Scars

I must say, this is my most favorite of all sizes!

It is the highly-recommended size for home treatment because of its safety and it can stimulate the production of collagen and elastin for treating mild to moderate cases of acne scarring.

Size 0.5mm derma roller can effectively treat most acne scarring. So, if you have combination of any of these acne scars like icepick, boxed scars or rolling scars, this size is a good one to start with.

This is not a “quick fix” for your acne scars so being consistent is needed for you to see dramatic results. However, you will see and feel the difference on your skin every after session.

For many, this size is more skin-friendly because of minimal to zero discomfort at all.

A numbing cream is not really needed but if you are someone with low pain tolerance, you can do so.

Expect some redness after rolling, but don’t worry because it goes away in an hour or so. This is normal in microneedling therapy.



Other benefits:

  • Your skin texture gets better after 1-2 sessions. You will notice that your skin is plumped, and fine lines will become less noticeable.
  • Aside from acne scarring, it can also target other skin imperfections like age spots, hyperpigmentation and skin discoloration.
  • Perfect for facial rejuvenation as it can give you that fresh glow and radiance. If you dermaroll at night, you will notice the difference when you wake up in the morning.
  • Great for enhancing the absorption of skincare products for optimum results



  • Takes a longer time of treatment when used with deep, pitted, and stubborn scars.


How painful is this needle size?

  • In terms of pain, this one comes with a little sting, but very tolerable. I’ll give it a 4 (out of 10).


How often to use?

  • If you are looking for a regular treatment, this one is recommended for you since it can be used once a week.
  • If you are a beginner, you can use it once every 2 weeks on your first month. Once you feel that your skin has adjusted to the treatment, from the 3rd session onwards, you can switch to once a week frequency.

1 mm Dermaroller for Acne Scars


This derma roller size is more effective to be used on deep scars or on stretch marks / cellulite to induce new collagen and elastin production.

This is due to the longer depth of the needles that can penetrate into the skin to more effectively break down the collagen on the skin’s upper layer, and aids in the repair by producing more collagen so the scarred skin can have new tissues.

Over time, those deep scars will be shallower and the tissue will get softer, resulting to an improvement in the scar’s color, appearance and texture.

A derma pen or a derma stamp like the one in Rejuviss 5-in-1 Collagen Booster Derma Roller Kit comes with 12 microneedles in 1.0mm depth. I find this very effective when targeting deep scars like ice pick or boxed scars. It is also easy to use in areas like the temples, below the eye are and near the lips..



Other benefits:

  • Along with faster healing of acne scarring, it is also effective for orange peel skin – large, open pores, dimpled and rough textured-skin.
  • It makes your skin more elastic, giving you that tightening effect so your skin wont sag or loose.
  • This size of derma roller is used for body related concerns like cellulites, stretch marks, or hair loss.



  • The pain level is higher as compared to 0.5mm microneedle derma roller.
  • For some people with sensitive skin, skin redness will take more hours to disappear.


How painful is this needle size?

  • In a scale of 10, I’d give it a 6-7 level for pain. But with regular use, you will be able to get used to this needle size very quickly.
  • For those with sensitive skin and low pain tolerance, you will need a numbing cream or topical anesthesia to alleviate discomfort.


How often to use?

  • The 1.0 mm derma rollers or stamps can be used ONCE A WEEK.


1.5 - 2.0 mm Dermaroller for Acne Scars

For more severe cases of acne scarring, these derma rollers are clinically used. Thus, these sizes are NOT SAFE FOR HOME USE and DONE BY PROFESSIONALS ONLY.

It is used on scars that are about 2millimeters wide or more, and when your pores look dilated with round, deep holes, and steep sides.

Essentially, this size is not for someone who will try derma rolling for the first time.

And even if you have been accustomed to derma rolling, microneedles this long are not for home use.

It works the same way as the size 1.0mm does; only with deeper penetration.

But put in mind that this is only to be administered professionally due to the pain associated with its usage. A topical anesthesia is applied onto skin when using this derma roller size.


Other benefits:

  • Aside from acne scarring, it can be used in your hands, arms, thighs and tummy for the treatment of severe wrinkles, stretch marks, and sagging or loose skin.
  • Effective treatment for skin imperfections that have become stubborn and left untreated for a long time



  • Longer downtime and skin recovery needed
  • It can be expensive because it will be performed in the clinic
  • You need to set an appointment with a doctor
  • Very risky and can cause infection when used at home


How painful is this needle size?

  • Pain is not tolerable, so I say it’s a 10! You can only feel it pain-free when there’s an anesthesia, but you can feel the sting when it wears off.
  • Your skin will feel tender and painful after the session.


 How often to use?

  • These derma rollers can be used every 6-8 weeks, depending on how fast the skin can recover from it. Your dermatologist or a registered aesthetician will assess your skin condition.

Best Products to use with Dermaroller

I got a lot of questions about aftercare treatment when microneedling.

Let me explain it further here:

After you use a dermaroller, your pores or skin channels are open. This is the best time for you to put a skincare product because it can penetrate into the deep layer of skin, so it becomes more effective.

In this case, a serum is highly recommended to be applied. Why?

Because a serum is more liquid in nature and with the right formulation, it can aid in the faster healing and recovery of skin.

However, you have to carefully choose the formula to be used because some ingredients can irritate your skin after the treatment. For example, serum with AHA  can cause peeling effects and should not be used after dermarolling.

Aftercare treatment includes the use of your skincare products such as moisturizers and derma roller serum for acne scars.

It is necessary to incorporate them with your microneedling treatment for quicker skin recovery and maintaining moisture.

Gladly, Rejuviss has a derma roller kit for acne scars! Our best seller bundle includes the 5-in-1 Advanced Derma Roller System that can be used for face and body, and the Advanced Antioxidant Serum, formulated with a unique blend of 16 natural botanical ingredients plus Vitamin C and Vitamin E, making it a perfect serum to apply after derma rolling.

Best Derma Roller Size for Acne Scars: Summary

Derma rolling can be quite daunting especially if you are a beginner, so let me summarize the main points below:

The following are the different sizes of derma rollers that can be used for Acne Scars treatment:


  • Size 0.5 mm derma roller
    Highly-recommended size for home treatment for mild to moderate cases of acne scarring.

    It is effective to induce collagen production to treat indented , boxed or rolling scars, large and open pores.

    It is best for enhancing the absorption of your skin care products and gives you smoother, and softer skin texture.

    Not only can it treat scars, but it can also reduce and eliminate signs of aging.


  • Size 1.00 mm derma roller
    This size is safe to be used for treating moderate to severe cases of deep acne scarring like icepick, boxed, rolling scars, or combination of all mentioned.

    It allows deeper skin penetration for scars that are less than 2mm , making it more effective to stimulate the production of collagen and elastin.

    As a result, deep scars can be shallow and looks softer with refined texture over time. You’ll get smoother and tighter skin.


  • Size 1.5 -2 mm derma roller
    Longer microneedle sizes that are used for treating more severe cases of acne scarring.

    Since it can be risky and cause infections, it can only be used and performed by a trained professional in a skin clinic.

    The 2mm dermaroller for acne scars is best to be used for deep, pitted, ice pick scars that are 2mm wide or more in size.
