Microneedling – also called “Collagen Induction Therapy” (CIT) – is one of the most discussed treatments in modern aesthetic medicine. But does it really work? What do the studies say? And who is it suitable for? We provide a scientifically based overview.
What exactly happens during microneedling?
During microneedling, ultra-fine sterile needles (length 0.25 mm to 2.5 mm, depending on indication) create targeted micro-injuries in the skin. These micro-channels activate three central regeneration processes:
- Inflammation phase (day 1–3): growth factors are released
- Proliferation phase (day 4–14): fibroblasts produce new collagen and elastin
- Remodeling phase (weeks to months): the new collagen matrix matures
The result: firmer, smoother and visibly rejuvenated skin – without thermal damage like in laser therapy.
What do studies say about effectiveness?
Landmark study 2008
The German research group led by Dr. Matthias Aust (Hannover Medical School) published a landmark paper in the renowned journal Plastic and Reconstructive Surgery: In 480 patients, microneedling showed significant improvement in wrinkles, scars and skin laxity – histologically proven by a significant increase in collagen and elastin.¹
Acne scars: up to 80% improvement
An Italian study on 32 patients with acne scars (Fabbrocini et al., 2009) showed an average improvement of scar depth by 57% after two microneedling sessions.² A larger review (Alster & Graham, 2018) confirms: microneedling is a safe, effective treatment for atrophic acne scars with results comparable to fractional laser therapy.³
Wrinkles and skin aging
A South Korean study (El-Domyati et al., 2015) examined 10 patients with photoaging and wrinkles before and after six microneedling sessions two weeks apart. Result: significant increase in type I and type III collagen as well as elastin – microscopically documented.⁴
Who is microneedling suitable for?
The treatment is particularly suitable for:
- First signs of skin aging (fine lines, loss of firmness)
- Atrophic acne scars and post-inflammatory hyperpigmentation
- Enlarged pores
- Pregnancy and stretch marks
- Tired, dull skin without visible glow
When is microneedling NOT suitable?
You should avoid microneedling in case of:
- Active skin infections (herpes, bacterial infections)
- Acute acne flare-ups with inflammatory pustules
- Tendency to keloid scarring
- Blood clotting disorders or use of blood thinners
- Pregnancy and breastfeeding (as a precaution)
- Skin cancer in the areas to be treated
Dermaroller vs. professional microneedling
Cheap dermarollers (from €15) are sold in drugstores and online as “home microneedling”. We strongly advise against this. The reasons:
- Home devices have needle lengths under 0.3 mm and can hardly stimulate collagen
- Non-sterile conditions lead to infection risks
- Wrong technique can cause pigmentation disorders, scars and skin damage
- Needles become dull over time and tear the skin
Professional microneedling is performed with medically certified devices (e.g. Dermapen 4, SkinPen Precision), sterile single-use attachments and consideration of individual skin parameters.
What should you consider after treatment?
- Day 1–2: Light redness like a sunburn, possibly minimal swelling
- Day 3–7: Gentle skin peeling possible – don’t scratch off!
- 48 hours: No make-up, no sauna, no sport, no direct sunlight
- 2 weeks: Consistent SPF 50+ sun protection, mild care without acids/retinol
How many sessions are necessary?
For visible results, most dermatologists recommend 3–6 treatments at intervals of 4–6 weeks. Maintenance treatments every 6–12 months sustain the result long-term.
