Many people see stretch marks appear on their body after rapid weight gain, so it is logical to question whether the stretch marks will go away after that weight is lost. Unfortunately, the short answer is probably not—but there are exceptions!
Stretch marks are caused when your body shape changes, forcing the skin to stretch farther than it is used to. This pulling causes tears in the lower layers of skin, which manifest as red “stripes.” As time goes on, these tears will heal and form scars deep in the middle layers of your skin. Once these marks become scars, they are permanent, meaning that their appearance is harder to treat.
When you lose weight, your skin will shrink along with your body. If your stretch marks were formed recently (aka they are still red), then they will likely fade as your skin reverts to its usual size. If your stretch marks are white or silver and have been on your body for a longer period of time, then chances are they will still remain after you have lost weight. These silver stretch marks are actually scars, and will not heal or fade simply because the weight is lost. Even though your skin has shrunk, these scars are now a permanent fixture of the lower layers of your skin. However, all hope is not lost! You can still treat the appearance of these stretch marks with creams or laser treatments. Even though they will not remove the scars entirely, they can reduce the silvery appearance of these marks.
