Stretch marks (striae) form when deeper skin layers stretch and tear. Prevention focuses on hydration, steady weight changes, nutrition, and moisturizing. Home remedies may improve skin feel but lack strong evidence; dermatologic options like retinoids, microneedling, and lasers offer more consistent results - especially for newer marks.
Stretch marks are dermal scars that fade but rarely disappear; early topical retinoids and in-office procedures (lasers, microneedling, radiofrequency) can reduce their appearance, while over-the-counter creams offer limited proof.
Stretch marks form when skin stretches faster than it can adapt. Treatments - topicals, lasers, microneedling - can improve appearance but do not guarantee complete removal. Early marks respond better than older ones.
