Stretch marks and body scars affect most people at some point, whether from growth spurts, pregnancy, weight changes, or injury. While they’re natural and nothing to be ashamed of, many people seek ways to minimize their appearance. Here’s what actually works.
Understanding Stretch Marks
Stretch marks (striae) form when the skin stretches rapidly, causing the collagen and elastin fibers to rupture. New stretch marks appear red or purple (striae rubrae) and gradually fade to white or silver (striae albae). The treatment approach differs depending on whether they’re new or old.
Treatment Options for New Stretch Marks
Early intervention is more effective. Prescription retinoids like tretinoin can improve the appearance of new stretch marks by stimulating collagen production. Hyaluronic acid has shown promise in clinical studies for both prevention and early treatment. Laser therapy, particularly pulsed dye laser for red marks, can significantly improve appearance.
Treatment Options for Mature Stretch Marks
Older, white stretch marks are more challenging to treat. Microneedling stimulates collagen production and has shown good results in clinical studies. Radiofrequency and laser treatments can improve texture. However, results vary significantly between individuals, and no treatment can completely erase stretch marks.
Body Scars
Silicone gel sheets and silicone-based scar gels are the gold standard for hypertrophic scars. They flatten and soften raised scars over time with consistent use. For dark scars, ingredients like niacinamide, vitamin C, and alpha arbutin can help fade discoloration. Sunscreen is critical to prevent scars from darkening further.
