Stretch marks are really common, and many of us will develop some over the years. There’s a huge variation in how people are affected, with some people having one or two, and others having seemingly hundreds. Rest assured, in most cases they are completely normal, and treatment isn’t necessary. If you really want to try something to reduce the appearance of your stretch marks, read on to see what you should (and shouldn’t!) be trying.
What are stretch marks, and why do they form?
Stretch marks, also known as striae, are common, occuring in up to 70% of people. They are fine lines that appear on the skin, often after a period of growth or stretching of the skin. When looked at under a microscope, there’s a reduction in collagen and elastin, the proteins that keep skin plump, firm and elastic. New stretch marks often look red, purple or pink, while older stretch marks look white or silvery.
Stretch marks can develop during puberty, pregnancy, after weight gain, in weight lifters, and as a result of certain medications and medical conditions.
Why do some people get stretch marks, and some people don’t?
Some people are genetically more likely to develop stretch marks than others. In addition, hormonal factors, the rate of growth, other medical conditions and medications all contribute.
How can I prevent developing stretch marks?
There aren’t any clinical studies that have shown with confidence that any treatment prevents stretch marks. Very weak evidence suggests that 15 minutes of massage with bitter almond oil, hyaluronic acid and Centella asiatica extract may reduce the development of stretch marks in pregnancy
What treatments are available for stretch marks?
Treatment of stretch marks can be difficult, but they often become less visible with time. There are lots of topical preparations that claim to prevent or treat stretch marks, but most of these have limited or no evidence to support their use. Topical retinoids and silicone gels may help. Vascular laser may improve the colour of red stretch marks, and radiofrequency and certain other lasers may improve the appearance of stretch marks.
