Stretch mark

From WikiMD's Food, Medicine & Wellness Encyclopedia

Stretch marks or striae are a form of scarring on the skin with an off-color hue. They are caused by tearing of the dermis, which over time may diminish, but will not disappear completely. Stretch marks are often the result of the rapid stretching of the skin associated with rapid growth or rapid weight changes.

Causes[edit | edit source]

Stretch marks are caused by a variety of factors, including:

  • Pregnancy: Most women experience stretch marks during pregnancy as the skin stretches in numerous ways to make room for the developing baby. This continuous tugging and stretching can cause stretch marks.
  • Weight gain: Rapid weight gain can cause stretch marks. When the skin is stretched too quickly, the collagen and elastin may rupture, resulting in stretch marks.
  • Puberty: Rapid growth is typical in young people going through puberty. This can lead to stretch marks.
  • Corticosteroids: Long-term use of corticosteroid creams and lotions can decrease levels of collagen in the skin. Collagen strengthens and supports the skin, and a reduced amount can lead to stretch marks.

Treatment[edit | edit source]

There are several treatments for stretch marks, including:

  • Topical treatments: Creams, gels, lotions, and cosmetic surgery have all been proposed as treatments for stretch marks, although there is little medical evidence to support the effectiveness of such treatments.
  • Laser therapy: Laser therapy is a common treatment for stretch marks. The lasers can be used to stimulate the skin's production of collagen, elastin, or melanin.
  • Microdermabrasion: This type of treatment involves a hand-held device that blows crystals onto skin. These crystals gently remove a fine layer of skin, promoting the growth of new, more-elastic skin.

Prevention[edit | edit source]

Preventing stretch marks may be difficult, but there are several steps you can take to reduce your risk:

  • Maintain a healthy weight: Avoid yo-yo dieting and aim to lose weight at a healthy pace. If you're noticing rapid weight gain, talk to your doctor.
  • Stay hydrated: Keeping your skin hydrated helps it retain its elasticity. Aim for 8 glasses of water a day.
  • Eat a nutrient-rich diet: Diets rich in certain nutrients, such as vitamins A and C, as well as zinc, can help keep skin healthy and reduce the risk of stretch marks.
