It sucks that I'm an expert on the subject but since I am...
Yeah I'm studying in college to be a dermatologist so here's what I know about stretch marks. Get our your pens, girls (and, yes, you GUYS, too
Here's what the thread already knows:
- Everyone gets stretch marks. Girl, guys, dogs, andything with collagen can get em.
- Stretch makrs usually rely on genetics; that's the easiest way to find out if you're atleast prone to getting them. Ask your mom if she got them while growing up or when she was pergnant.
Here's what can cause them:
- A little background info: Stretch marks occur in the dermis, a lower layer of skin. Collagen is housed there. Usually it happens when the collagen in the dermis is stretched past its ability to hold together. When the collegen "snaps," so to speak, it results in the ugly buried scar we all call STRETCH MARKS! Therefore, stretch marks are caused by a malfunction in the collagen located in the dermis layer of the skin. Here are some examples of what can damage the dermis:
+ Weight gain
+ Weight loss
+ Steroids (Including corticosteroids, a compound found in Cortizone creams. This is another reason why males tend to get them. So if a tiny wee-wee isnt reason enough to stop using steroids, how about a tiny wee-wee AND stretch marks?

)
+ Muscle bulk
+ Anything else that can thin or weaken your dermis.
- Why worry? Stretch marks are more than superficial scars on your booty and belly. It means you have weakened or damaged collagen. It could signal fading vision and even weak joints in the (near) future. It may also mean you have a condition called Cushing's disease. Go see a dermatologist and find out if your stretch makrs could mean something more is goin on under your skin.
Here's what most of the thread got WRONG!:
-
No amount of moisturizer or cream is going to work. Any lotion that promises to get rid of them IS a scam. That I can say for sure. Especially if the creme/lotion/moisturizer is white (in other words, not clear or translucent... the clearer types work moderately well i.e. Mederma, StriVectin, Vitamin E, pure from the caplet soothes them but still doesnt get to the root of the rpbelm...) Lotions and creams and moisturizers dont penetrate that deep. NOT EVEN PALMER'S COCOA BUTTER. So if your friend used it on her belly while she was pregnant and didnt get stretchmarks, she probably wasn't going to get them anyway.
-
Exercise won't get rid of them. exercise tones muscles, not skin, ESPECIALLY if your collagen has already torn. Skin stretches and contracts with muscles, but once your skin has stretched from stretch marks, it cant contract or expand as well.
-
Microdermabrasion isn't that expensive. It's getting cheaper as the demand for microderm. procedures goes down (due to over-the-counter microderm. products like Neutrogena and L'Oreal ones). Microdermabrasion isnt even the only skin treatment that works. Chemical peels do a fairly good job as well (I used the Neutrogena one on some of my stretch marks and it showed improvement.)
-
There's no cure for stretch marks short of having your skin resurfaced somehow.
What do to about them:
-
Microdermabrasion works. It usually takes a few treatments but if you're deadbent on getting rid of your scars, it can be worth it.
-
Chemical peels work. But it has the same advantages/ disadvantages as microderms.
-
Mederma, StriVectin, Nutrius work but only moderately well and you have to have ALOT of patience and persistence as some of these treatments require multiple applications throughout the day.
-
Lasers work but they are expensive. "Puls dye" lasers today only target redness so they only work on fresh stretch marks. Another thing about these lasers is that they only really work well on fair complexions so ti eliminates some of the potential patients who could benefit from it. The newest adition to the laser family is the "Gentle Yag" laser which emits light and heat in high amounts into the deepest layers of the skin in order to stimulate collagen production. This might be the best hope for stretch marked men and women.
-
Get some Retin A. You're not really gonna find it in anything on the shelves, so see your dermatologist and get some prescribed to you. It burns!, but it works pretty well and is kind of cheap.
In the meantime, if you want a quick coverup...
- Sally Hansen Airbrush Legs ($9 at drugstores) works well to coverup just about anything on your legs.
- Self tanner can disguise them some.
Some words of advice and consolation:
- Stretch marks do fade with (alot) of time. That can be a good thing for some, because it means they stay red long enough for them to be treated with a pulse-dye laser. It's bad if you want to get into that bikini by next summer.
- Something like 85% of pregnant women get them.
- In general, 60% of everyone walking around you has them.
- I saw a model in an ad in my InStyle magazine who had them on her butt (she was in a swimsuit, so you could see them very well). She was a model!!! In a nationally printed ad!!! For a big designer (I don't want to call names because I can't remember which designer it was for, but when I find out, I will repost)!! It was very comforting to see. SO WEAR YOUR BIKINI IF YOU WANT TO!
- Persistence will get you far in this game.
- Science is coming a long way. Finally dermatologists are finding out what to do when THE LARGEST ORGAN ON YOUR BODY breaks down. You'd think there would be more current research on the subject, but I guess they're realizing now that collagen is VERY important (without it your bones can weaken, your eyes can go bad, and other things... they just MANIFEST in a superficial thing like stretch marks).
- Sometimes you can tell when you're getting stretch marks. You skin will usually feel itchy, so DON'T SCRATCH! It'll tear your little dermis all up.
Hope this helps girls and guys! If you have any questions, I'm an open book on the subject. I may have left out some stuff...
