What works, what does not, and the realistic timeline for visible change.
Stretch marks are scars. The fibres within the dermis have torn and the skin has healed with a different architecture, sometimes shiny, sometimes pigmented, often slightly indented. No treatment will erase them completely. Treatments can soften them significantly.
The first thing we look at is age and colour. Red or purple stretch marks, called striae rubrae, are recent and have more vascular involvement. They respond better to treatment than older, white stretch marks (striae albae), which are more established scars. Newer marks tend to soften noticeably with a proper protocol. Older marks see meaningful but more modest change.
What works. Microneedling and RF microneedling are the foundation of stretch mark treatment. They create controlled micro-injuries in the skin and trigger remodelling of the collagen and elastin in the affected dermis. RF microneedling reaches the deeper layers where stretch marks live, which is why we prefer it for established marks.
A course is typically four to six sessions, four to six weeks apart. Some clients add fractional laser between sessions for the pigmented or textural component. The full result takes three to six months after the last session as the collagen remodels.
What does not work. Topical creams marketed as stretch mark cures. They may improve hydration and surface appearance briefly, but they do not change the underlying scar architecture. Crash exfoliating treatments. Anything promising single-session results.
What helps the result. Consistent home care with retinoids (outside of pregnancy and breastfeeding), vitamin C, and SPF on the treated area. Stable body weight during the protocol. Patience with the timeline.
We photograph stretch marks at the start of every protocol because the day-to-day change is small but the cumulative change is real. The comparison shot at six months is what tells the truth.
