Stretch Marks: Causes and the Best Treatments to Reduce Them

Stretch marks (striae) are extremely common — they affect most people at some point and are nothing to be ashamed of. But if they bother you, the good news is that modern dermatology can make them significantly less visible, especially when treated early.

What Causes Stretch Marks?

Stretch marks form when the skin is stretched faster than it can adapt, causing the collagen and elastin in the dermis to tear. Common triggers include:

• Pregnancy
• Rapid growth during puberty
• Quick weight gain or weight loss
• Bodybuilding and rapid muscle gain
• Long-term use of steroid creams or medical conditions

Red vs White Stretch Marks

Fresh stretch marks are red or purple (striae rubra) — this early stage responds best to treatment. Older stretch marks turn white or silvery (striae alba) and are harder to treat, though they can still be improved. The takeaway: the earlier you treat them, the better the result.

Why Creams Alone Rarely Work

Most over-the-counter creams only moisturise the surface and cannot rebuild the torn collagen deep in the skin. They may slightly improve early marks but rarely remove established ones. Effective treatment needs to stimulate collagen in the dermis.

Treatments That Actually Help

• Micro-needling / MNRF — creates controlled micro-injuries that boost collagen.
• Fractional laser resurfacing — remodels the skin and improves texture and colour.
• Chemical peels — improve surface texture and tone.
• Combination treatment — often gives the best results.
• A dermatologist will tailor the plan to your stretch marks, skin type and stage.

Results are gradual and usually need a series of sessions, but most patients see a real reduction in the depth, texture and colour of their stretch marks.
