Start early. Once they pass the initial stage (when they are red, purple, pink, or brown, depending on the color of your skin) and become white or silver (usually with deep indentation), it's far more difficult to minimize them
Educate yourself about topical treatments. Many are advertised to "repair" stretch marks, but few have actually been proven to be effective. Here's the scoop on what's available:
- Wheat germ oil - may help improve stretch marks in their early phase.
- Glycolic acid - increases collagen production; can be administered in higher doses by a dermatologist (costs about $100 USD and requires three or four office visits before you see results); has not been fully studied by itself. A good topical treatment that contains Glycolic acid as its primary ingredient is Stretta from Zenmed. Glycolic Acid helps to gently remove the Skin.
- Vitamin C - certain formulations might increase collagen production, but they'll only help with early-stage stretch marks; for best results, combine with glycolic acid; taking 500 mg of Vitamin C supplements three times a day may also help.
- Relastin - the effectiveness of this product is unknown and unverified
- Peptide-containing products - these "repair" creams are ineffective; there's no evidence that they work.
- Retinoids - they're fairly effective in increasing collagen and elastic production in the early stages, but they should be avoided if you're pregnant or nursing; they're more effective when used in combination with glycolic acid.
- Topical tretinoin can lighten stretch marks and reduce their size if applied in the earlier stages. Specifically, tretinoin cream is effective against stretch marks that are less than 6 weeks old, and are still pink or red, but it should not be used during pregnancy. It works by helping to rebuild collagen, but it's not effective against older stretch marks.
