1. Target Scars or Stretch marks
Some people swear by this method, helping to reduce the look of scars and stretch marks. It's simple and affordable, helping to reduce the appearance of problematic areas. Apply a piece of duct tape to the affected area, leave it on overnight, removing it after a shower.
This will starve the tissue of oxygen and in turn, white blood cells rush to the area. This is similar to the suggested wart treatment. Although it will not erase a scar or stretch marks, duct tape can reduce visibility.
