What are stretch marks?
Stretch marks (striae) are skin scars that form when the skin stretches faster than it can produce collagen. Collagen and elastin fibers tear and leave the typical streaks behind.
Why do stretch marks develop?
Rapid body growth, pregnancy, fast weight gain or loss, intense strength training. A genetic tendency raises the risk.
How do you reduce stretch marks?
Fresh (pink-purple) marks respond better to skincare. Retinol stimulates collagen (not during pregnancy). Massage with oils and hyaluronic acid improves elasticity. Procedures such as microneedling, laser and chemical peels are offered by a dermatologist.
How do you prevent stretch marks during pregnancy?
Regular belly massage with shea butter or almond oil from the first trimester. Managing your weight and drinking enough fluids support the skin's elasticity.
