Stretch marks are the off-coloured stripes or streaks formed on the skin as a result of swift stretching of skin or weight changes. They mainly appear on abdomen due to pregnancy or obesity. In dermatology, they are termed as Striate. They are formed due to hormonal changes related to pregnancy, puberty, hormone replacement therapy, etc. Stretch marks can be commonly seen on waist, thighs, lower backs, hips, breasts, arms, and buttocks.
Causes: Stretch marks are not a disease, which infects the human body, but are the scars formed due to contraction and expansion of skin. They are basically caused by stretching of the skin. Their appearance depends on the type of skin. These ugly stretch marks are caused due to:
- The physical stretching of the skin at the end of pregnancy.
- Extraordinary weight gain, especially on arms, thighs, etc.
- Use of certain medications, including lotions, pills, Corticosteroid creams, and steroids.
