Stretch marks are extremely common and completely harmless, but many people would like to make them less noticeable. Understanding why they form helps explain what treatment can do.
What causes stretch marks
Stretch marks form when skin stretches faster than its collagen and elastin can adapt, causing small tears in the deeper layers. Common causes include:
- Pregnancy
- Growth spurts during adolescence
- Rapid weight gain or loss
- Building muscle quickly
- Hormonal changes and certain medications
Red vs. white stretch marks
New stretch marks are often red or purple and respond best to treatment. Older marks fade to white or silver and are harder, but still possible, to improve.
Treatments that help
Microneedling
Stimulates collagen to improve texture and depth.
Laser treatments
Fractional lasers remodel skin and can reduce discoloration.
Radiofrequency microneedling
Combines microneedling with heat for firmer, smoother skin.
PRP
Growth factors can enhance collagen-building treatments.
Realistic expectations
Treatment can soften stretch marks significantly, but it rarely erases them completely. A series of sessions usually gives the best results.
