Microneedling, which involves the use of small needles to create controlled micro-injuries in the skin, can be effective in treating certain types of acne scars. The procedure stimulates collagen production, which can improve the appearance of scars over time. It can be particularly beneficial for atrophic (indented) acne scars. Let’s take a look at what derma roller size for acne scars is most effective.

Best Derma Roller Size for Acne Scars

Overall, the size of the derma roller that is considered best for treating acne scars is between 0.5mm to 1.5mm needle length. However, it’s important to note that using dermarollers at home carries some risks, so do your research and follow safety instructions. 

In general, the effectiveness of microneedling for acne scars can vary depending on the individual and the severity of the scars. Some people may see significant improvement in their acne scars, while others may experience more modest results. The following chart shows what derma roller size for acne scars should be used.

0.5mm – suitable for home use this needle length is commonly used for improving the absorption of skincare products and addressing mild acne scars, shallow depressions, and help with overall skin texture and tone.

0.75mm – provide a deeper level of collagen stimulation compared to 0.5mm, and address more noticeable acne scars and atrophic scars.

1mm – effective for treating moderate acne scars and atrophic scars. It can reach deeper into the skin’s layers and stimulate collagen production, helping to improve the appearance of scars over time.

1.5mm – more suitable for experienced users and is generally used by professionals in a clinical setting for more severe acne scars, including deep ice pick scars and rolling scars.

It’s essential to be cautious when using dermarollers with needle lengths of 1.0mm and above at home, as they can cause more discomfort and may carry a higher risk of complications if not used correctly. For deeper or extensive scarring, it’s advisable to seek professional microneedling treatments performed by dermatologist. 

Regardless of the needle length chosen, it’s crucial to maintain proper hygiene by cleaning the dermaroller after each use. Also, follow a post-treatment skincare routine that includes soothing products to support the skin’s healing process.

What Are Acne Scars

Acne scars are skin imperfections or marks that are left behind after acne lesions have healed. When acne occurs, it can cause inflammation and damage to the skin’s deeper layers. As the body attempts to repair the damaged tissue, it can sometimes produce too much or too little collagen, leading to various types of acne scars. 

Overall, acne scars can be broadly categorized into two main types:

  • Atrophic scars, which result from a loss of tissue and appear as depressions or indentations on the skin’s surface. Some of the common subtypes of atrophic scars are boxcar scars, ice pick scars, and rolling scars.
  • Hypertrophic or keloid scars are the opposite of atrophic scars. They occur when there is an overproduction of collagen during the healing process, leading to raised and thickened areas of skin. Hypertrophic scars stay within the boundaries of the original acne lesion, while keloid scars extend beyond them.

Acne scars can have varying degrees of severity, and they can significantly affect your self-esteem and confidence. The type of scarring and its depth can influence the choice of treatment for improving their appearance. Some treatments for acne scars include topical creams, chemical peels, microdermabrasion, laser therapy, dermal fillers, and microneedling. 

Skincare Ingredients For Acne Scars

Reducing acne scars requires a combination of methods including effective skincare ingredients that promote skin healing, collagen production, and overall skin health. Moreover, combining derma rolling (microneedling) with a proper skincare routine can speed up the process of reducing acne scars. Here are some key skincare ingredients that are beneficial for reducing acne scars and that can be used after dermarolling:

  • Vitamin C – a powerful antioxidant that helps brighten the skin and promote collagen synthesis. Not only can it improve the appearance of acne scars but also even out skin tone. Look for serums or creams containing L-ascorbic acid, a stable and potent form of vitamin C. (We love Mad Hippie Vitamin C Serum)
  • Niacinamide – a form of vitamin B3 that has anti-inflammatory properties and can help reduce redness and hyperpigmentation caused by acne scars. (Try Ordinary Niacinamide 10% + Zinc 1% Serum for Face)
  • Peptides – amino acid chains that can support collagen production and improve the skin’s elasticity, making them beneficial for reducing the appearance of acne scars. (We love Youth To The People Triple Peptide serum)
  • Growth Factors – serums with this ingredient can help stimulate collagen production and accelerate the skin’s healing process, which can improve the appearance of acne scars. (Try Le Mieux TGF-B Booster)

When using these skincare products, it’s essential to introduce them gradually into your routine, especially if you have sensitive skin. Remember that consistent use and patience are key when treating acne scars, as results may take time to become noticeable.

How to Combine Dermaroller & Skincare

Here’s a step-by-step guide on how to do dermarolling safely and effectively:

1. Choose the right derma roller size for acne scars. For acne scars, a derma roller with needle lengths ranging from 0.5mm to 1.5mm is generally recommended and is safe for home use. But longer needles should be used by professionals in a clinical setting.

2. Prep your skin. Cleanse your face thoroughly with a gentle cleanser and pat it dry before the dermarolling session. Also, avoid using any products that may irritate your skin or cause sensitivity.

3. Start dermarolling. Gently roll the dermaroller over the affected areas of your skin. Apply light pressure and roll in different directions (vertical, horizontal, and diagonal) to ensure even coverage. But be cautious and avoid excessive pressure, as this can cause more harm than good.

4. Post-treatment skincare. After derma rolling, your skin will be more receptive to skincare products. Apply a soothing serum or a growth factor-rich product that promotes collagen production to aid in skin repair.

5. Sunscreen is a must. You can protect your skin from the sun by applying a broad-spectrum sunscreen with at least 30 SPF, as sun exposure can worsen acne scars and hinder the healing process.

6. Avoid irritating ingredients. In the days following the derma rolling session, avoid using skincare products that contain harsh or irritating ingredients, such as retinoids or acids.

7. Be patient. Reducing acne scars takes time and multiple sessions. So don’t expect immediate results, as collagen production and skin healing occur gradually.

8. Frequency of treatment. The frequency of derma rolling sessions will depend on the intensity of your treatment and your skin’s ability to recover. In general, dermatologists recommend space out sessions every 2-6 weeks depending on the needle length used.


When choosing derma roller size for acne scars, take into consideration the type of scars you have and the severity of the scars. In general, needle lengths between 0.5mm and 1mm are safe and effective for home use.

Also stay consistent. Like with any skincare routine, consistency is key to achieving the best results, so stick to your skincare routine and derma rolling schedule.

Remember, while derma rolling can be effective for acne scars, it’s essential to approach it with caution and follow the guidance of a professional. If done incorrectly or too frequently, derma rolling can lead to skin irritation, sensitivity, or other complications. So safety and proper technique should always be prioritized.
