Check if you have stretch marks

What to do about stretch marks
It's not always possible to prevent stretch marks.
The best way to reduce your chance of getting them is by maintaining a healthy weight.
Many creams and lotions claim to prevent, reduce or remove stretch marks. But there's very little evidence these work.
There are some treatments that may help make stretch marks look better, but they will not get rid of them.
- retinoid (often called tretinoin) creams or hyaluronic acid – these may help if used on new stretch marks, but you should not use retinoid creams if you're pregnant
- light or laser treatments
- microdermabrasion, which removes a thin layer of skin
You would need to pay for these treatments as they're not available on the NHS.
See a GP if you have large, often dark, stretch marks and:
- have more fat on your chest and tummy, but slim arms and legs
- a build-up of fat on the back of your neck and shoulders
- a red, puffy, rounded face
These could be symptoms of Cushing's syndrome.
