If you’re dealing with acne scars, surgical scars, stretch marks, or thinning hair, you’ve likely searched for solutions that are safe, effective, and require minimal downtime. One treatment that continues to gain medical and cosmetic recognition is microneedling, also known as collagen induction therapy. But does microneedling really work for scars, stretch marks, and hair loss? And what kind of results can you expect?
In this article, we’ll explore:
- How microneedling works
- The evidence behind microneedling for scars, stretch marks, and hair loss
- What the treatment involves
- Realistic expectations and aftercare
- How in-clinic treatments can be supported with at-home dermarolling
Let’s break down the science and benefits of this powerful regenerative therapy.What Is Microneedling?
Microneedling is a minimally invasive treatment that uses tiny, sterile needles to create micro-injuries in the skin. This controlled trauma triggers the body’s natural wound healing response, stimulating the production of collagen and elastin. These structural proteins are essential for firm, smooth, and healthy-looking skin.
This process is medically known as collagen induction therapy, and it can be performed on the face, scalp, and body.
At Chiswick Clinic, we use the XCellarisPro TWIST, a professional microneedling device from Germany that is clinically approved and designed for both epidermal and dermal rejuvenation.
Microneedling for Scars: Can It Really Help?
Does microneedling work for scars?
Yes—when performed correctly, microneedling for scars is supported by a growing body of clinical evidence. It works particularly well for:
- Acne scars (especially atrophic or ice-pick scars)
- Surgical scars
- Trauma-induced scarring
By stimulating collagen renewal deep within the dermis, microneedling can help remodel scar tissue, improving its texture, colour, and elevation.
What technique is used?
For general facial rejuvenation, our clinic typically starts with a depth of 0.5mm. But when treating visible scars on the face, we increase the needle depth up to 2.5mm, focusing only on the scarred areas. This higher penetration triggers more intensive collagen repair where it’s needed most.
For body scars, we use a depth of 2.5mm, and treatment sessions are spaced 6 months apart, as body skin tends to heal more slowly.
How many sessions are needed?
For most scars, we recommend one to three sessions, with follow-up assessments after 2 to 6 months, depending on the scar’s location and severity.
Microneedling for Stretch Marks: Visible Improvement
Stretch marks (striae distensae) occur when the skin stretches quickly and the underlying collagen matrix breaks down. They are common after pregnancy, weight fluctuations, or during puberty.
How does microneedling help?
Microneedling for stretch marks promotes collagen induction in the damaged dermal layer. Over time, new collagen fibres rebuild the structure beneath the skin, making the marks:
- Less visible
- Smoother in texture
- More uniform in colour
Microneedling results for stretch marks
Clients typically undergo a course of three treatments, spaced 6 weeks apart.
Results vary based on age, skin type, and stretch mark maturity. Mature (white) stretch marks can still respond well, although results may take longer to appear.
Is it painful?
Microneedling is well tolerated. No numbing is required, even on the body, and patients typically experience only mild redness for 24 hours.
Microneedling for Hair Thinning and Hair Loss
Hair thinning, particularly menopausal or post-menopausal hair loss, is another condition where microneedling shows promise. The treatment stimulates blood flow and growth factors around the hair follicles, which can improve:
- Hair thickness
- Hair density
- Scalp health
Microneedling hair regrowth before and after
Studies have shown positive microneedling hair regrowth before and after results, especially when paired with PRP, exosomes, or hair growth serums.
Our approach:
- Needle depth on scalp: up to 0.8mm maximum
- Serum application: up to 0.75% strength
- Pre-treatment: scalp is wiped with disinfectant (no washing for 5 days post-treatment)
How many sessions are needed?
Hair thinning typically requires a series of treatments, and results can be enhanced with home care kits.
In-Clinic Microneedling + Home Dermaroller = Better Results
Studies support the use of home dermarollers between professional sessions. At Chiswick Clinic, we provide safe, medical-grade dermaroller kits for home use with full guidance.
The recommended protocol:
- One professional in-clinic treatment
- Followed by one home rolling session two weeks later
- Then the next in-clinic session
This staggered approach supports ongoing collagen production without overwhelming the skin, helping patients maintain momentum and see better long-term outcomes.
Combination Therapies: Boosting Microneedling Results
Microneedling is a powerful treatment on its own, but it becomes even more effective when combined with:
- PRP (Platelet-Rich Plasma): Boosts natural growth factors
- Exosomes: Supports cellular communication and regeneration
- ZO® Skin Health Products: Enhances exfoliation, hydration, and recovery
These options can be discussed during consultation to create a personalised treatment plan.
Who Is Microneedling Suitable For?
Microneedling is suitable for most skin types, including darker skin tones, when properly primed. For Fitzpatrick types IV to VI, we use products before treatment to minimise the risk of post-inflammatory hyperpigmentation. Any pigmentation that does appear usually resolves within 10 days.
Post-Treatment: What to Expect
After microneedling, you may experience:
- Mild redness for up to 24 hours
- Tightness or sensitivity (like mild sunburn)
- Some dryness or light flaking in the days that follow
Aftercare tips:
- Use only recommended products
- Avoid sun exposure for at least 2 weeks
- No active ingredients (like retinol or AHAs) for 7 days
- Apply SPF daily to protect the healing skin
- No makeup for the first 24–48 hours
Final Thoughts: Is This the Best Treatment for Scars, Stretch Marks, or Hair Thinning?
Microneedling is one of the best treatment options for scars, stretch marks, and hair thinning, especially for those seeking a safe, non-surgical solution with minimal downtime.
Its results are gradual but long-lasting, thanks to the body’s natural healing ability. When combined with professional-grade skincare, regenerative serums, and personalised care, microneedling offers a powerful way to restore and renew the skin and scalp.
