Call me weird but i find stretcmarks and cellulite Sexy!
I suffered stretchmarks a long time ago when i quit smoking and put on alot of weight in a very short time; Bio oil is a scam.Nilitumia mpaka cocoa butter before it was banned in Europe for its dangerously high mercury content i used to have a Naija guy smuggle it from America and it also doesn`t work.
It is one thing a woman getting stretchmarks but believe me it really got to my confidence as a man but thankfully i was going out with a "momo" so its not like she was going to call me Fat! - Mwanaume ni strategy and thankfully they naturally disappeared over time.
As @Unicorn said laser treatment..I have tried anything to reduce mine the best product I used was Black opal complex fade gel
but this is for skin toning so it reduced the stretchmarks but pretty expensive
