What do stretch marks look like?
Are red and white stretch marks different problems?
When skin stretches faster than its collagen can remodel — pregnancy, adolescent growth, rapid weight or muscle gain, corticosteroid exposure — the dermis tears in parallel lines. Fresh tears are striae rubra: red-to-purple, still vascular and biologically active. Left alone they mature into striae alba: pale, slightly sunken atrophic scars. The distinction is not cosmetic trivia — active rubra respond meaningfully better to collagen-inducing treatment than settled alba, which is why the treatment window is worth knowing about during and after pregnancy or bulking.
What the evidence supports
Because striae are dermal scars, treatments that work are collagen-induction treatments. A systematic review and meta-analysis of microneedling for striae distensae reports significant improvement across trials [1], and fractional energy platforms extend the same principle with heat-driven remodelling — the same device families covered in the acne scar literature [2]. Dr Sin Yong's stretch mark programme and RF microneedling stage treatment by striae age and skin type — pigment-safe settings matter in Singapore skin.
Stretch mark treatments compared: which suits red marks and which suits white
The right stretch mark treatment depends on the stage. Red marks are still vascular and active, so they are treated earlier and more gently. Dr Sin Yong uses FSX and fractional CO2 laser for red marks. White marks are settled, thinned scars, so treatment has to deliver energy into the dermis to remodel collagen. No option erases a mark; the realistic aim is softer, flatter and less visible.
| Option | How it works | Stage it suits | What it cannot do |
|---|---|---|---|
| Vascular-directed laser | Light aimed at the blood vessels in an active mark | Red or purple striae rubra | Remodel the thinned collagen of a white mark |
| Microneedling | Fine needles create controlled micro-injuries that prompt collagen repair; supported by a meta-analysis of trials in striae | Red and white marks | Erase the scar |
| RF microneedling | Needles deliver radiofrequency heat into the dermis to remodel collagen | White striae alba, with settings chosen for skin type | Treat the redness of an early mark on its own |
| Fractional laser | Columns of laser energy drive repair of the dermis | White marks; settings kept pigment-safe in Asian skin | Match the colour of the mark to the skin around it |
| Creams, oils and cocoa butter | Moisturise the surface | Comfort and itch | Reach or remove a dermal scar |
Who should wait
During pregnancy and breastfeeding, the marks are staged and the timing of treatment is reviewed afterwards rather than started straight away. Striae that appear suddenly and widely, without pregnancy, growth or a change in weight, or alongside weight gain in the face or trunk, bruising or high blood pressure, need a medical review of the cause before any cosmetic treatment. A fresh tan is also a reason to delay laser, because the scar tans differently and the risk of pigment change rises.
For how the plan is put together after staging, see stretch mark treatment in Singapore.
What doesn't work for stretch marks?
No cream removes a dermal scar; moisturised scar tissue is still scar tissue. Bio-oils and cocoa butter have affection but not evidence for removal. Tanning worsens contrast — the scar tans differently from surrounding skin. And “stretch mark removal” as a phrase over-promises: the evidence supports visible softening and flattening, not erasure. That is worth having — sold honestly.
“A stretch mark is a scar, and scars remodel — they do not vanish.”

How to remove stretch marks: what works at home and what needs a clinic
If you are looking for how to get rid of stretch marks, no cream, oil or device removes them completely. What can change is how visible they are, and the stage matters: early red or purple marks respond better than settled white ones. Home care helps at the margins, mostly early; deeper change needs treatment that works in the dermis.
What has some evidence at home
- Tretinoin on early marks: in a small randomised trial, a tretinoin cream improved early, active stretch marks compared with a plain cream. It is a prescription retinoid, can irritate, and is not used in pregnancy or while breastfeeding.
- Creams with hyaluronic acid or Centella asiatica: some trial evidence for prevention in pregnancy, though a systematic review found the evidence for topicals thin overall.
- Massage with a moisturiser: helps itch and comfort; in trials, cocoa butter and olive oil showed no effect on the marks.
- Self-tan and sun protection: a self-tan blurs contrast; a real tan increases it, because the scar does not tan.
What should not be done at home
Home dermarollers and pens reach too shallow to remodel a scar, and reused needles carry infection risk. Home laser and IPL gadgets, bleaching creams on red marks and scrubbing also do not help, and can irritate the skin.
What is different in Asian skin
In skin types III to V, early marks can look purple-brown rather than pink, and white marks stand out more against the surrounding skin. Heat-based treatments carry a higher risk of post-inflammatory darkening, so devices and settings are chosen for the skin type, a recent tan delays treatment, and sun protection before and after matters as much as the treatment itself.
When to see a doctor
See a doctor while marks are still red if you want treatment, or at once if striae appear suddenly and widely without pregnancy, growth or weight change. Clinic options by stage are on stretch mark treatment in Singapore, with RF microneedling for settled white marks and a separate guide to post-pregnancy stretch marks.
Dr Sin Yong’s Viewpoint
The single most useful thing I can tell a stretch-mark patient is about colour: red is the responsive window, white is the settled state. People wait years for marks to 'fade' — and they do fade, from red to white, which is not gone. If yours are still red, that is the time to act, not the time to wait.
