Stretch marks, unfortunately, are pretty normal, especially around puberty. It doesn't matter if you're underweight, or overweight. Did you recently go through a growth spurt? My boyfriend who's very skinny has stretch marks on his back, just from growing taller. Luckily, they fade in time. Unfortunately however, there is nothing that will remove stretch marks, so don't waste your money. You can try using cocoa butter to help prevent any further stretch marks.

There is no specific medical treatment for stretch marks and in most cases, there is no need to see your doctor about them. Most stretch marks are not particularly noticeable and fade over time.
If you have several stretch marks that affect a large part of your body, or if you are worried that they look unsightly, there may be treatments available.
However, there is little or no medical evidence to show that these treatments will work, so it is important to be realistic about what they can achieve.

Ive tried searching and not come up with any suggestions.

I have red stretch marks on my thighs and hips from sudden growth and weight gain, Im going on holiday in summer and ideally I would like them to be silver by then. can anyone recommend me anything from within the uk that will help the fading?

I really do think that vitamin E cream is great for this, it has great healing properties and has been known to really reduce scars and other skin blemishes. I am sure that you can get it at Boots but try to get it as pure as you can and do not expect an overnight result, you have to keep at it massaging the area every day for several weeks. But I think it should work but he time you need it. Good luck
