What Is Microneedling Good For?

By LIV Clinic · Medically reviewed by Dr. Narathai Vichienkalayarut, M.D. · Published October 26, 2026

Controlled injury sounds alarming until you realise it is exactly how skin is persuaded to rebuild itself.

What is microneedling good for? Microneedling — collagen induction therapy — is best for acne scarring, uneven texture, enlarged pores, fine lines and stretch marks, working by creating controlled micro-injuries that prompt the skin to produce new collagen and elastin.

How microneedling works

Controlled micro-injury

Fine needles create tiny channels in the skin, triggering the body’s repair response — which is why it is also called collagen induction therapy.

Rebuilding from within

That repair response prompts new collagen and elastin, gradually improving the skin’s structure rather than just its surface.

What it treats well

Microneedling is most useful for:

• Acne scarring, particularly rolling and boxcar scars
• Uneven or rough skin texture
• Enlarged-looking pores
• Fine lines and early ageing
• Stretch marks on the body
• Overall skin quality and firmness

The evidence

For texture and collagen

A clinical and histometric study of microneedling combined with fractional radiofrequency found significant improvement in skin tightening and texture, with a significant increase in collagen type I.

For stretch marks

A comparative study of microneedling as a stand-alone treatment for stretch marks found it safe and effective for both early and mature striae, with improvements sustained at three and six months after the final treatment.

What it does not do

No lifting or volume

Microneedling does not lift sagging tissue or restore lost volume — for those, skin tightening or filler are the appropriate tools.

Not for active acne

Treating over active, inflamed acne risks spreading infection and new scarring, so acne should be controlled first.

Sessions and results

A course, not one session

Most protocols use three to six sessions spaced four to six weeks apart, depending on the concern.

Results keep building

Collagen remodelling continues for months after treatment, which is why studies assess results at three and six months rather than immediately.

Safety and skin type

Generally well tolerated

Expect redness resembling sunburn for one to three days, with mild flaking as skin renews.

Pigmentation caution

In more pigmented skin, conservative depth and diligent sun protection reduce the risk of post-inflammatory pigmentation.

Preparing for and recovering from microneedling

Preparation and aftercare:

1. Have a consultation to confirm microneedling suits your concern.
2. Get any active acne under control first.
3. Avoid sun exposure and pause retinoids as advised beforehand.
4. Expect redness and mild flaking for one to three days.
5. Avoid make-up, heat, sun and heavy exercise for 24–48 hours.
6. Complete the course and allow months for collagen to build.

Frequently asked questions

Safety and consultation

Microneedling is a medical procedure and, like any energy-based or resurfacing treatment, carries some risk — common temporary effects can include redness, mild swelling and sensitivity, while less common effects such as pigment changes are minimised by correct settings for your skin type. Results vary from person to person, and no specific outcome can be promised. This article is general information, not medical advice.
