Again since its summer I am going to combine a few answers from Quora here as well.  The first one is to whether or not to even treat them.  So let me just preface with the fact that you should not treat anything because someone is shaming you, period.  That person is an idiot and not worth caring about.  We treat stretch marks as a big part of our business. BUT let me repeat, you should not care about people who are so shallow that they notice or care if you have them.  Do not be embarrassed. Any woman who has had children probably has stretch marks from the skin stretching to give birth. Nothing could be more beautiful. People who notice and or care, are themselves, not worth caring about. Everyone is too busy being self conscious to notice what you perceive as your flaws. Do not worry at all about it. 

You should only treat them, if YOU want to treat them.  We have been getting rid of stretch marks in New York, to our patients complete satisfaction for over 10 years via Carboxytherapy. What do you think ? Carboxytherapy Before And After Images It uses a needle to break up the stretch mark and infuses Co2 gas to increase the circulation. Ironically Carboxytherapy also is great for scars. But guess what ? A stretch mark is like a deep scar. A laser, as some would offer, is not going to go deep enough. Worse than that, a laser is most likely going to leave dark or light spots, hyperpigmenation or hypopigmentation. Its like trying to tattoo or white out a stretch mark. You are not eliminating it like microneedling does. Carboxytherapy is microneedling plus increasing circulation. The additional effect of the increased circulation is a bonus to heal the stretch mark. PS anyone who says CO2 is dangerous should re examine their medical credentials and their high school diploma. You are excreting Co2 with every breath you take. Also Laparoscopic surgery is now widely performed to treat various abdominal diseases. Currently, carbon dioxide is the most frequently used gas for insufflation of the abdominal cavity (pneumoperitoneum). So perhaps the Doctors who think Co2 is dangerous should maybe take a little trip to the operating room if they havent been there lately to see the latest technologies. PS Carboxytherapy uses minute amounts of Co2, abdominal insufflation uses massive amounts of Co2.
