In short. Improvement in appearance is the only realistic aim. Why before-and-after images mislead, and how to judge honestly whether a course of treatment did anything.
Key points
- Your own mark, photographed in the same light, from the same distance, before the course and again several months after it.
- That comparison can show a genuine change, and it can also show that a course changed nothing.
- It is the standard a clinic should be willing to be held to.
Every conversation about treating a stretch mark runs into the same wall. A stretch mark is a scar in the dermis, the fibres that tore are not replaced by any treatment available, and the aim of treatment is therefore improvement rather than removal.
What the ceiling means in practice
A red mark can become less red. A surface that is depressed or finely wrinkled can become somewhat smoother. A mark that is very visible in ordinary light can become less so. What does not happen is the mark disappearing, and the size of the change is usually modest. Anyone who describes it otherwise is describing something that does not exist.
Why before-and-after images mislead
Three things go wrong with them. A red mark photographed at its reddest and again a year later shows the natural fading of the scar as though it were the treatment. Lighting and angle change between sessions, and images are selected, so the ones showing change are the ones published. An image cannot tell you what a treatment did.
The only comparison worth trusting
Your own mark, photographed in the same light, from the same distance, before the course and again several months after it. That comparison can show a genuine change, and it can also show that a course changed nothing. It is the standard a clinic should be willing to be held to.
What improvement is worth
A mark that is a little less red, or a little smoother, is a real change to the person living with it, and treating it is not unreasonable because the change is partial. What is unreasonable is paying for a course on the understanding that the mark will be gone.
How to judge a result honestly
Decide before treatment what would count as worth it to you: less colour, less texture, less visibility in a particular light, or simply that you tried. Photograph the mark in the same conditions, then look again months later, when the skin has settled, rather than while the redness of the treatment itself is still passing.
When to stop
A mark that has not changed across a full course is unlikely to change across the next one. Stopping at that point and being told plainly that nothing more is on offer is a better outcome than another course bought on the strength of hope. It is also the point at which living with the mark becomes the sensible plan.
Walk away if any of these is offered
- A guarantee that the marks will be removed, or a figure for how much will go.
- A course bought before anyone has examined the marks and recorded their stage.
- An injected preparation whose contents are not described to you in full.

Frequently asked questions
How do I know whether a treatment actually did anything for my marks?
By comparing standardised photographs rather than your memory. The same light, the same distance, the same angle, taken before the course and again some months after it, with no other skin changes in between. Memory adjusts to a mark within weeks, and a mark that looks better to you may look identical in a photograph taken in the same light.
Is a clinic promising to remove my stretch marks trustworthy?
No, and the promise is the useful part of the consultation. A stretch mark is a dermal scar, and nothing available restores the fibres that tore. Anyone offering removal is either describing improvement in looser language or does not understand what they are treating, and neither is a good reason to proceed.
If nothing removes a stretch mark, why treat one at all?
Because a mark that is less red, less raised or less distinct in ordinary light can matter a great deal to the person who has it, and that is a legitimate aim. Improvement is a real outcome even when it is partial. What does not work is paying for a course in the belief that the mark will be gone, and then judging the result against that.
Risks & Limitations
- No treatment removes a stretch mark. Improvement in colour and texture is the realistic aim.
- A mark that has already gone pale answers to far less than one that is still red.
- Change is judged from standardised photographs over months, not from the first weeks.
- Laser and light can leave pigment change, particularly in skin that darkens readily after injury.
When to Seek Care
- Marks that appeared while you were taking a steroid medicine, by mouth or on the skin.
- Marks with weight gain around the middle, easy bruising or muscle weakness.
- Marks with unusual joint flexibility, or a family history of aortic or heart valve problems.
- Blistering, spreading redness or increasing pain after a treatment on the skin.
