Stretch marks are not just due to pregnancy, weight gain/loss or aging. In fact they are a normal part of puberty for most girls and boys.  When a person grows or gains weight really quickly (like during puberty), that person may get fine lines on their body called stretch marks or striae.

Stretch marks often start off as reddish or purplish in color and then become glossy skin that appears streaked in silver or white. In dark skinned individuals stretch marks usually appear light brown in color.

Most girls and women have stretch marks, which tend to show up on the breasts, thighs, hips, and butt.  Many women get them during pregnancy. And while they're more common in girls, boys can get stretch marks too.

People who are obese often have stretch marks. Bodybuilders are prone to getting stretch marks because of the rapid body changes that bodybuilding can produce.

Fortunately, stretch marks often turn lighter and virtually disappear over time. But the fact that stretch marks usually fade and become less noticeable over time can be of little consolation if you spend a lot of time in a bathing suit.

Some lighter skinned people find that sunless tanning treatment (both over the counter lotions and sprays and in salon types of treatments) can help cover up stretch marks. Regular tanning in the sun and tanning beds won't change the color of stretch marks.

You can also buy makeup matched to the tone of your skin. These products tend to be messy and may not be the best solution for a swimmer. There are lots of beach wear and bathing suits styles that work well for hiding stretch marks. Many swimmers prefer high neck bathing suits that hide the chest and cover the butt.

There are dozens of creams and concoctions that claim to eliminate stretch marks, the truth is that most of them are just that - claims, they don't work.

Take heart  - you're young and healthy - stretch marks are the least of your growing pains.   Drink plenty of water to keep your skin hydrated and toned. Eat foods rich in vitamin CD and E. Concentrate on your inner beauty and staying fit. If you're really bothered - consult a dermatologist.
