Hi I really need help with getting rid of stretch marks I have. Im 16 and I keep losing and gaining weight. Please help

The thing with stretch marks is once you have them, you're stuck with them. The damage has been done and you just have to live with them. You could have them laser removed but that's a whole different thing. You can prevent more though by keeping your skin healthy and hydrated. Use lotions that contain aloe, vitamin e, or cocoa butter. A combination of these would really make your skin healthier.
