I think my doc had me on retina-a before but my skin is sensitive and it just kinda made my skin red and irritated. I beleive it's supposed to work by kinda getting rid of the top layer of skin and promoting new skin cells, might be wrong.
Anyways i'm an ex-325lb fat kid so stretchmarks are a fact of life for me. When I was younger and fat they were horrible, 3 years i avoided EVER having my shirt off in public. The stetch marks were red and my skin was reasonably white. They were on the inside of my arms, outside of my chest, from my armpits down my sides to my love handles, along my love handles and also along my stomach. Then they appeared on my traps as the weight of my chest stretched my skin there too. It was just twisting a kinfe to be an obese teenager and also to look at yourself as hideous with the stretchmarks.
Now, it's 4 years later, the weight (fat) came all off and i put back on a large amount of muscle. Every summer i strive for a dark tan and ever year the stretch marks fade more and more. I should try some coca butter sometime.
One thing i did notice though, is that in my first year at university, not long after i lost the fat, i was really self concious the first few times i was getting naked with girls. But guess what, not one commented, and not one ever stared at them or looked at them funny. One asked if they were scars from a scratch and that was it. My self confidence grew and after that I really didn't pay much notice to them after that.
I thought I'd share that aspect of my life beacuse for the longest time the stretchmarks made me miserable, and i'm glad to say that they do fade and they have no impact on my self image whatsoever anymore, nor should they for anyone else.
