Treatment for birthmarks

Most birthmarks do not need treatment, but some do. This is why it's important to get a birthmark checked if you're worried about it. A birthmark can be removed on the NHS if it's affecting a person's health. If you want a birthmark removed for cosmetic reasons, you'll have to pay to have it done privately. Possible treatments for birthmarks include: medicines – to reduce blood flow to the birthmark, which can slow down its growth and make it lighter in colour laser therapy – where heat and light are used to make the birthmark smaller and lighter (it works best if started between 6 months and 1 year of age) surgery – to remove the birthmark (but it can leave scarring) Information: Help and support Birthmark Support Group: getting help
