Derma Rolling A Method for Scar Reduction
Derma Rolling for Scars: Does It Work?
Derma rolling may improve the appearance of certain indented scars, particularly some rolling and shallow acne scars. However, it cannot remove every type of scar, and incorrect use can make the skin worse.
A derma roller is a handheld device covered with small needles. As the device is rolled across the skin, the needles create multiple tiny punctures. This is intended to trigger a controlled wound-healing response and encourage collagen remodelling.
Professional microneedling treatments use a similar principle, but at-home derma rolling and clinic-based microneedling are not the same. Professional equipment, hygiene procedures, treatment depth and practitioner training can significantly affect the safety and outcome.
The Short Answer
Derma rolling may help certain shallow, indented scars appear smoother over time. It is less likely to improve deep ice-pick scars, raised scars or keloids.
It should never be used over:
- Active acne
- Infected skin
- Open wounds
- Fresh surgical scars
- Inflamed eczema or dermatitis
- Cold sores
- Skin that is already damaged or irritated
Established scars should be assessed by a qualified professional before treatment. A dermatologist or experienced practitioner can identify the scar type and explain whether microneedling, another procedure or no treatment is the most appropriate option.
What Is a Derma Roller?
A derma roller consists of a handle attached to a rotating barrel covered in very small needles.
When rolled across the skin, the needles enter at changing angles as the cylinder moves. This creates numerous small punctures in the skin’s surface.
Derma rollers are often marketed for:
- Acne scars
- Uneven texture
- Fine lines
- Stretch marks
- Enlarged-looking pores
- Hair and scalp treatments
However, marketing claims do not guarantee that a device will be effective or suitable for your skin.
A device capable of reaching scar tissue can also cause injury, infection and additional scarring if used incorrectly.
How Is Derma Rolling Supposed to Help Scars?
Scars form when the skin repairs itself after an injury or inflammation. The amount and arrangement of collagen produced during healing affect how the scar looks.
Indented scars form when tissue is lost or insufficient collagen is produced. Raised scars form when the body produces excessive scar tissue.
Derma rolling attempts to create controlled micro-injuries around an indented scar. The subsequent healing response may encourage collagen remodelling and gradually make the skin’s surface look more even.
This process takes time. Any improvement develops gradually rather than immediately after treatment.
Derma rolling cannot simply erase scar tissue, and results vary considerably between individuals.
Which Types of Scars May Respond?
Rolling Acne Scars
Rolling scars are broad depressions with gently sloping edges. They can create a wavy or uneven skin texture.
Some rolling scars may respond to professional microneedling. However, scars attached to deeper tissue may require another procedure, such as subcision.
Shallow Boxcar Scars
Boxcar scars are round or oval depressions with more defined edges.
Shallow boxcar scars may show some improvement with professional treatment. Deeper boxcar scars can be more difficult to treat and may require a combination of procedures.
Deep Ice-Pick Scars
Ice-pick scars are narrow openings that extend deeply into the skin.
A derma roller is unlikely to correct deep ice-pick scars. A dermatologist may recommend a more targeted treatment.
Surgical Scars
A derma roller should never be used on a fresh surgical wound or a scar that has not fully healed.
Even after healing, the suitability of microneedling depends on the scar’s location, age, appearance and the person’s medical history. Speak to the surgeon, GP or dermatologist before treating a surgical scar.
Stretch Marks
Stretch marks are a type of scar that develops when the skin stretches or shrinks quickly.
Professional microneedling may improve the appearance of some stretch marks, but results vary. At-home rolling is unlikely to produce the same controlled treatment as a professional procedure.
Raised and Keloid Scars
Raised scars form when the body produces too much scar tissue.
Derma rolling is generally unsuitable for hypertrophic or keloid scars without specialist medical advice. Creating further trauma could aggravate abnormal scar formation.
Anyone with a personal or family history of keloids should inform the practitioner before considering any needling treatment.
Scar Types and Derma Rolling Suitability
| Scar type | Appearance | Is derma rolling likely to help? |
|---|---|---|
| Rolling acne scars | Broad, shallow depressions | Some may respond |
| Shallow boxcar scars | Defined, shallow indentations | Some may respond |
| Deep boxcar scars | Deeper, sharply edged depressions | May need combined treatment |
| Ice-pick scars | Narrow and deep openings | Usually limited benefit |
| Flat dark marks | Pigmentation without an indentation | Not technically a scar |
| Surgical scars | Marks following surgery | Requires medical clearance |
| Hypertrophic scars | Raised scar within the original wound | Usually unsuitable |
| Keloid scars | Raised scar extending beyond the original wound | Avoid without specialist advice |
What Derma Rolling Cannot Do
Derma rolling cannot:
- Guarantee complete scar removal
- Treat every type of scar
- Correct active acne
- Remove pigmentation immediately
- Safely treat fresh or infected wounds
- Replace medical treatment
- Produce professional results without professional equipment and training
Photographs online can also be misleading because lighting, camera angle, makeup and image editing can dramatically change the appearance of scars.
Derma Roller Versus Professional Microneedling Pen
Although both treatments use needles, there are important differences.
| Feature | At-home derma roller | Professional microneedling |
|---|---|---|
| Movement | Rolled manually across the skin | Controlled stamping or vertical motion |
| Treatment depth | Often fixed and difficult to control | Selected according to the treatment area |
| Hygiene | Depends on the user | Professional infection-control procedures |
| Skin assessment | Usually none | Completed before treatment |
| Suitability for scars | Limited | Can be planned for particular scar types |
| Complication support | None immediately available | Practitioner can identify and manage problems |
| Results | Uncertain for established scars | Better controlled, but not guaranteed |
A roller’s curved movement can cause needles to enter and leave the skin at an angle. Excessive pressure, repeated passes or worn needles can increase the risk of unnecessary damage.
Can You Safely Derma Roll at Home?
At-home derma rollers are widely available, but easy access does not mean they are risk-free.
Possible complications include:
- Infection
- Bleeding
- Prolonged redness
- Skin irritation
- Post-inflammatory pigmentation
- Broken capillaries
- Cold-sore reactivation
- Allergic reactions
- Further scarring
- Uneven texture
- Damage caused by bent or blunt needles
There is also a risk of transferring bacteria across the face, particularly if the roller is passed over active acne.
If a roller penetrates deeply enough to affect established scar tissue, it also penetrates deeply enough to cause complications when used incorrectly.
For meaningful scar treatment, professional assessment is the safer approach.
Never Use a Derma Roller Over Active Acne
A derma roller should not be passed over pustules, cysts, inflamed spots, infections or broken skin.
Rolling across active acne may:
- Increase inflammation
- Spread bacteria
- Damage already inflamed skin
- Delay healing
- Increase pigmentation
- Create additional scars
The NHS advises people with moderate or severe acne, nodules or cysts to see a GP because appropriate treatment can help prevent permanent scarring.
Control active acne before considering treatment for the scars it has left.
Who Should Avoid Derma Rolling?
Derma rolling or professional microneedling may be unsuitable for people with:
- Active inflammatory acne
- Skin infections
- Open wounds
- Active cold sores
- Eczema, psoriasis or dermatitis in the treatment area
- A tendency to develop keloids
- Poor wound healing
- Bleeding disorders
- Conditions affecting the immune system
- Medicines that affect bleeding or healing
- Recent use of certain prescription acne treatments
- Recent surgery in the treatment area
This is not a complete list. Tell the practitioner about every medical condition, allergy, medicine, supplement and previous cosmetic treatment.
Do not stop prescribed medicine without speaking to the clinician who prescribed it.
How Long Does Scar Improvement Take?
Collagen remodelling is gradual. Scars will not disappear immediately after a needling treatment.
The number of treatments required depends on:
- The scar type
- Scar depth
- The size of the treatment area
- Skin tone
- The person’s healing response
- The device being used
- The treatment intensity
- The time allowed between appointments
Some people may see only a small improvement. Others may be advised to combine microneedling with another procedure.
A responsible practitioner should give realistic expectations rather than promising flawless skin.
What Happens After Professional Treatment?
The skin can temporarily appear:
- Red
- Warm
- Slightly swollen
- Dry
- Tight
- Sensitive
- Mildly flaky
The practitioner should provide written aftercare instructions.
Seek advice if you experience worsening pain, spreading redness, pus, blistering, significant swelling, fever or other signs of infection.
Derma-Rolling Aftercare
Follow the instructions supplied by your practitioner. Immediate aftercare commonly involves:
- Avoiding unnecessary touching
- Keeping the skin clean
- Using only recommended products
- Avoiding scrubs and exfoliating acids
- Pausing retinoids until advised
- Avoiding fragranced products
- Avoiding swimming, saunas and heavy sweating temporarily
- Protecting the skin from sunlight
- Not picking or peeling the skin
Do not apply a product simply because it is described as natural, gentle or hydrating. Recently treated skin may react differently from intact skin.
Can You Use Hyaluronic Acid With Derma Rolling?
Hyaluronic acid is a humectant used to support skin hydration, but not every hyaluronic acid serum is sterile or designed for use during needling.
Do not apply an ordinary cosmetic serum during professional microneedling unless the practitioner has specifically approved it for that purpose.
Once the skin has recovered sufficiently, a straightforward hyaluronic acid serum may be reintroduced as part of an everyday hydration routine.
Hollyberry Cosmetics’ 1% high-molecular-weight hyaluronic acid serum contains three ingredients:
- Aqua
- Hyaluronic Acid
- Phenoxyethanol
It is designed to support everyday hydration. Ask your practitioner when it is appropriate to restart normal skincare following treatment.
Hyaluronic acid hydrates the skin, but it does not remove scar tissue or guarantee faster healing.
How to Choose a Professional Practitioner
Before agreeing to treatment, ask:
- What qualifications and training do you have?
- Are you insured for this procedure?
- Do you regularly treat my type of scar?
- How have you identified my scar type?
- Why is microneedling suitable for me?
- Which device will you use?
- What products will be applied?
- How is the equipment cleaned or disposed of?
- What results are realistic?
- What are the risks for my skin tone?
- What aftercare will I receive?
- What happens if I experience a complication?
Do not feel pressured into purchasing a treatment package during the first consultation.
Frequently Asked Questions
Can a derma roller remove scars completely?
No. Derma rolling may improve the appearance of some indented scars, but it cannot guarantee complete scar removal.
Does derma rolling work for old scars?
The age of a scar is only one factor. Scar type, depth, location and your healing response also affect whether it may respond.
Can derma rolling make scars worse?
Yes. Incorrect technique, excessive pressure, contamination or treating unsuitable skin can cause infection, pigmentation changes and additional scarring.
Can I derma roll acne scars at home?
At-home rolling carries risks and may not reach established scar tissue effectively. Professional assessment is safer, particularly for deeper scars.
Can I use a derma roller on active acne?
No. Do not roll over active inflamed spots, pustules, cysts, infections or broken skin.
Does derma rolling help dark acne marks?
Flat dark marks are pigmentation rather than indented scars. They may need a different skincare or medical treatment plan.
Is derma rolling suitable for keloid scars?
It is generally unsuitable without specialist medical advice. Further skin injury may aggravate abnormal scar formation.
How often should you derma roll?
There is no single safe schedule suitable for everyone. Treatment timing depends on the device, depth, skin condition and healing response. Do not follow a generic social-media timetable.
Can I use retinol after derma rolling?
Do not restart retinol until the practitioner says your skin has recovered sufficiently. Applying it too soon may cause significant irritation.
Can I apply makeup after treatment?
Ask the practitioner when makeup can safely be reapplied. Applying it too early may irritate the skin or introduce contamination.
Final Verdict
Derma rolling may improve certain shallow, indented scars, but it cannot remove every type of scar and is not suitable for active acne, fresh wounds, raised scars or keloids.
At-home devices offer less control and carry risks including infection, pigmentation changes and further scarring. If a scar concerns you, the safest first step is an assessment from a qualified professional who can identify the scar type and recommend an appropriate treatment.
Treat active acne first, keep expectations realistic and never use a derma roller on inflamed, infected or broken skin.
Summary
Derma rolling uses a needle-covered roller to create controlled micro-injuries in the skin. It may improve some rolling and shallow boxcar scars by encouraging collagen remodelling, but it is unlikely to correct deep ice-pick, raised or keloid scars. Derma rollers should not be used over active acne, infection, open wounds or fresh surgical scars. At-home rolling carries risks including infection, pigmentation changes and further scarring, so professional assessment is recommended.
