Fractional laser for stretch marks – how we can help you at TBL Medical

Stretch marks (striae) are small, linear scars that occur when the skin is stretched rapidly—for example, during pregnancy, growth spurts, or weight change. They are harmless, but can be cosmetically bothersome.

Stretch marks (striae) are small, linear scars that occur when the skin is stretched rapidly – for example, during pregnancy, growth spurts, or weight change. They are harmless, but can be cosmetically embarrassing. At TBL Medical, we offer fractional laser treatment with Fotona Dynamis SP Pro (with a complete handpiece portfolio) – an advanced platform that allows us to tailor treatment for both reddish stretch marks (striae rubrae) and older white ones (striae albae). If necessary, we can combine this with picosecond laser to enhance skin improvement and even out pigment differences.

Our goal is to provide a noticeable improvement in texture and appearance, while being honest about what is realistic: stretch marks can usually be significantly reduced, but rarely completely removed.

What does fractional laser do?

Fractional laser divides the energy into a network of microdots. Each dot creates a controlled, microscopic "treatment zone" surrounded by healthy skin. The body responds by repairing and producing new collagen and elastin, so that stretch marks gradually become narrower, smoother, and less visible.

Each laser beam creates a controlled, microscopic "hole" surrounded by healthy skin.

With Fotona Dynamis SP Pro, we can treat at two complementary depths:

  • Nd:YAG 1064 nm (deep, non-ablative) heats up the collagen layer and affects small blood vessels – particularly useful for red stretch marks.
  • Er:YAG 2940 nm (ablative/fractional) resurfaces the surface and upper dermis to smooth out texture and stimulate further remodeling.

This combination allows us to address both color and texture in the same treatment course – with precise dosing for different skin types.

Why Fotona at TBL Medical?

  • Versatility in one platform: We have all relevant handpieces and modes (SMOOTH®, FRAC3®, fractional Er:YAG, etc.), so that the energy can be tailored from mild to more intensive treatment – depending on skin type, area, and goal.
  • Safety focus: Er:YAG has lower heat diffusion than CO₂, which can reduce the risk of post-inflammatory hyperpigmentation, especially in darker skin types.
  • Combination options: We have modern picosecond lasers at our disposal. Fractional pico (LIOB effect) can provide deep stimulation with minimal surface impact and is a great addition for evening out color and enhancing the collagen response—especially in older, white stretch marks.
  • Large laser capacity: We are among the clinics with the most medical lasers in Bergen. This means the right tools for the right patient – every time.

What can you expect from the results?

  • Improvement, not complete removal: Typical improvement is often in the range of 40–70% after a series of treatments. Red, fresh stretch marks respond more quickly; white, older ones often require several rounds.
  • Gradual development: Collagen remodeling takes time. You will often see a clearer effect 6–12 weeks after each treatment, with further improvement throughout the series.
  • Number of treatments: Often 4–6 sessions at intervals of approx. 6–8 weeks.
  • Natural: The goal is to make stretch marks less visible and the skin smoother.
We always create a personalized treatment program based on skin type, area, the "age" of the stretch marks, and how much downtime you can accept.

How the treatment works

  1. Consultation and plan
    We assess skin type, medical history, sun habits, and goals. If necessary, we perform a test pulse/patch.
  2. Treatment session (30–60 minutes depending on the area)
    • Cleansing and, if necessary, anesthetic cream.
    • Deep heating (Nd:YAG or SMOOTH mode) to activate collagen and reduce redness.
    • Fractional Er:YAG to improve texture and smooth the surface.
    • Optional extra: Fractional picosecond laser for additional dermal stimulation and color matching.
  3. Post-processing
    • Cooling, soothing/occlusive cream.
    • Instructions for wound care and sun protection.

Downtime and side effects

  • Non-ablative steps (Nd:YAG/pico): typical redness 24–48 hours.
  • Fractional Er:YAG: mild micro-scars/“dots” for 3–7 days; slight swelling/stinging sensation during the first 24 hours.
  • Common, transient reactions: redness, slight swelling, dryness/flaking, tenderness.
  • Less common: temporary hyper-/hypopigmentation (reduced with good sun protection and correct protocol), infection (very rare with correct wound care).

We always optimize settings according to skin type to minimize risk – especially for darker skin tones or those prone to pigment reactions.

Who is suitable – and who should wait?

Well suited:

  • Red or white stretch marks on the stomach, hips, thighs, buttocks, breasts, upper arms, etc.
  • Patients who accept gradual improvement over several sessions.

Should be carefully considered/postponed:

  • Pregnancy/breastfeeding, active skin infection, impaired wound healing.
  • Recent isotretinoin (usually waiting period of 6–12 months).
  • Pronounced keloid tendency (we adapt or advise against).
  • Photosensitizing medications (to be clarified in consultation).

Before and after advice

Before:

  • Avoid sun exposure/self-tanning 4 weeks prior.
  • Stop using retinoids/strong acids in the area 5–7 days beforehand.
  • Come hydrated and without active rashes.

After:

  • SPF 50+ daily for at least 4 weeks.
  • Gentle cleansing + occlusive/moisturizing cream for spots/scabs that have fallen off naturally (do not pick).
  • Avoid hot baths, strenuous exercise, swimming pools, and active skin products for 3–7 days (until the skin is calm).

Combinations that can enhance the result

  • Picosecond laser (fractional): can increase dermal stimulation and even out skin tone with minimal downtime.
  • Vascular laser for targeted redness reduction in striae rubrae.
  • Medical skin program (retinoids/peptides/antioxidants) to support collagen and barrier function.
  • Microneedling as a supplement for deep, stubborn stretch marks – assessed on an individual basis.

We set up step-by-step protocols to balance power and downtime.

Frequently asked questions (FAQ)

Does it hurt?
Discomfort varies. Most people manage with anesthetic cream and/or cooling. Ablative steps may "sting" more, but are over quickly.

How quickly will I see results?
Often, a slightly smoother feeling/reduced redness early on. Visible, lasting improvement becomes apparent after 2–3 sessions and continues to develop in the weeks between sessions.

Can stretch marks disappear completely?
As scar structures, they are permanent. The goal is a significant reduction in visibility, not total removal.

How much does it cost?
The price depends on the area, intensity, and whether we combine technologies. We provide a specific price during a consultation after a medical assessment and plan.
