Stretch Marks

Stretch marks (Striae distensae) are the faint sometimes indented squiggly lines that often form during puberty during growth spurts and with excessive weight gain but in Pregnancy they are termed Striae Gravidarum. They can be red, pale, purple or brown depending on your skin colour. Most common area to find them during pregnancy is your tummy but also can be found on the breasts and upper thighs increasing as your pregnancy progresses and bump continues to expand.

They are harmless and do not cause pain but can for some be a cosmetic issue. After birth the stretch marks tend to fade in colour and reduce but is unlikely they will completely resolve and disappear.

Why Do They Happen?

When the middle layer of skin (dermis) becomes stretched beyond its usual capacity and broken in places as the collagen bundles in the skin get thinned out and have alterered fiber orientation. This can then lead to formation of stretch marks. With pregnancy they are more commonly developed due to weight gain, expansion of the bump stretching the abdomen skin and on the breasts swelling during pregnancy. Hormones in pregnancy can also make them more prevelant to develop.

Treatments

There are some natural ways you can try which all have some research behind their effectiveness.
