How quickly can microneedling treat acne scars?

“How long does it take to see an improvement in my acne scars after microneedling?” is one of the questions we get asked most often before booking our first session at ssskin!

Today you will have a clear answer on how long it takes for it to really work , but we will also talk about the factors that affect the results and especially what you can do to optimize each session.

What is microneedling?

Simply put, microneedling is a technique that helps the skin repair itself by creating tiny micro-channels on the surface of the epidermis without going beyond the first layers of the skin using a device with fine needles (a manual dermaroller or an electric dermapen).

Once these micro-lesions are created, the skin renews itself more quickly by stimulating the skin's natural regeneration and produces more collagen and elastin, two essential proteins in the repair of skin marked by acne scars.

How long does it take to see results on acne scars?

Microneedling results develop in stages or gradually. From the first session and up to 6 months of treatment, you will see a visible and stable transformation.

From the 1st session (2 to 4 weeks): no effects on scars

After the first microneedling session , the skin appears slightly smoother to the touch with a visible glow due to the increase in microcirculation. However, as for the appearance of scars, you will have to wait a little longer. The skin may also show some slight peeling. These are not yet spectacular results, but they are encouraging signs that skin cells are beginning to renew themselves.

After 2 to 3 sessions (1 to 2 months): the first visible improvements

After a series of 2 to 3 microneedling sessions spaced 4 to 6 weeks apart , the skin begins to appear more uniform and the edges of the scars become less sharp, as if "blurred", and the deep hollows begin to fill in, a sign that collagen synthesis has been triggered and is beginning to take effect.

After 4 to 6 sessions (3 to 5 months): notable results

At this stage, we begin to see a real difference in moderate to deep acne scars. The skin has had time to produce a significant amount of collagen and renew itself, and deep acne scars are reduced by 50 to 70% according to some studies. Even post-acne pigmentation fades.

6 months and over: continuous improvement

Collagen production continues for up to 6 months after the last session; thus, some scars can become almost invisible, especially the most superficial ones.

What factors influence the speed of results?

Several factors can affect how quickly microneedling results are visible on acne scars. These include:

1. The type of acne scars : atrophic scars, which are deeper, take longer to fade than pigmented scars, which are often more superficial.

2. The age of the scars : the older and more severe a scar is, the more time and sessions it will take to respond to microneedling.

3. Age and skin quality: Results are faster on young, dense skin that produces sufficient collagen.

4. Frequency and regularity of sessions : a regular rhythm and an adequate number of sessions spaced 4 to 6 weeks apart is essential to optimize the cumulative effects of the treatment.

5. Microneedling Post-Treatment Care : Skin continues to regenerate after each session, so it's essential to adopt a routine that supports and accelerates results.
   

How many microneedling sessions are needed to treat acne scars?

To effectively treat acne scars with microneedling, plan on between 3 and 6 sessions . For mild to moderate scars, 2 to 4 sessions are often enough to smooth skin texture, reduce indentations, and even out skin tone. For deep, old, or very marked scars, plan on between 5 and 6 sessions .

Can microneedling results be accelerated?

Yes, it is entirely possible to accelerate the effects of microneedling on acne scars:

By following a suitable post-treatment routine . The skin after microneedling is more receptive, and this is the ideal time to promote regeneration: by using moisturizing and healing treatments (rich in hyaluronic acid, peptides or centella asiatica), avoiding irritating products (acids, retinol) for at least 5 to 7 days and finally by applying SPF 50 sunscreen every day to avoid any hyperpigmentation.

By respecting a regular rhythm of sessions . A regularly spaced treatment optimizes and accelerates the results. It is recommended to have 3 to 6 sessions, spaced 4 to 6 weeks apart.

By combining microneedling with other clinical treatments . Microneedling + PRP or Microneedling + LED to boost collagen production and accelerate skin repair.
