Stretch marks are very common. They're harmless and often get less visible over time.

Common causes of stretch marks

Stretch marks are often caused by sudden growth or weight gain.

• are going through puberty
• lose or gain weight quickly
• are female
• are overweight
• use some kinds of steroid creams or tablets
• have a family member with 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.

They include:

• 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.
