I am 27 years old male, I have stretch marks on my shoulders and back. Is it a serious problem, what can be done to eliminate them, I went to some skin clinics and the doctors said it's a common issue don't bother about it but I want to get rid of them so they prescribed me to undergo some process called laser knitting. But what if I get the same problem after undergoing this process. Is there permanent method to get rid of the stretch marks.
