The most effective options for stretch marks depend on whether they’re new (red or purple) or old (white or silver). Newer stretch marks respond better to almost every treatment, so starting early gives you the best results. Your options range from over-the-counter creams with ingredients like Centella asiatica and tretinoin to professional procedures like laser therapy and microneedling, each with different levels of evidence behind them.
No single treatment erases stretch marks completely. But several can significantly reduce their appearance, especially when matched to the right stage.
Why Stretch Marks Form
Stretch marks happen when your skin stretches faster than its support structure can keep up. The middle layer of skin, the dermis, contains a network of collagen and elastin fibers that give skin its strength and bounce. When rapid stretching occurs (during pregnancy, growth spurts, weight changes, or muscle gain), those fibers break apart. The elastin in the mid-dermis degrades first, followed by a reorganization of collagen into dense, flat bundles that look and behave like scar tissue.
Fresh stretch marks appear red or purple because of increased blood flow and inflammation beneath the surface. Over time, they lose that vascularity and the collagen flattens into thin, horizontal bundles. The skin thins, the texture changes, and the marks fade to white or silver. At this stage, they essentially resemble mature scars, which is why older stretch marks are harder to treat.
Over-the-Counter Creams and Ingredients
Not all stretch mark creams are equal. A few ingredients have clinical evidence behind them, while many popular products rely more on marketing than science.
Centella asiatica is one of the better-supported ingredients. It stimulates the cells responsible for producing collagen and elastin. In one controlled trial, a cream containing Centella asiatica extract (sold under the brand Trofolastin) reduced the development of new stretch marks: 34% of users developed them compared to 56% in the placebo group. Among women who already had a history of stretch marks from puberty, the cream was reported to be 100% effective at preventing new ones during pregnancy. A separate study found a 60% reduction in the visibility of existing marks along with measurable improvements in skin elasticity.
Tretinoin (a prescription retinoid) at 0.1% concentration has shown clinical improvement, particularly on recent red stretch marks. It works by speeding up skin cell turnover and stimulating collagen production. The catch: tretinoin is not safe during pregnancy or breastfeeding. If your stretch marks are pregnancy-related, this option is only available postpartum.
Glycolic acid at various concentrations has also demonstrated improvements, especially on newer marks. It works by exfoliating the surface and encouraging fresh skin cell growth. Products with lower concentrations (around 10 to 15%) are available over the counter, while higher concentrations (20% and above) are used in professional peels.
Hyaluronic acid shows up in many stretch mark products, but the evidence that it prevents or meaningfully reduces stretch marks is weak. It’s a good moisturizer and supports skin hydration, which may improve the overall appearance of the skin, but don’t expect it to do the heavy lifting on its own.
Cocoa butter, olive oil, and almond oil are among the most commonly purchased remedies. Despite their popularity, clinical reviews have not found strong evidence that they prevent or reduce stretch marks beyond basic moisturizing. They won’t hurt, and keeping skin hydrated can reduce itching during stretching, but they’re unlikely to change the marks themselves.
Professional Laser Treatments
Lasers are among the most effective tools for stretch marks because they can reach the dermis and trigger the body’s own collagen-rebuilding process. Different lasers work better for different stages.
For newer, red stretch marks, lasers that target blood vessels tend to work well. A long-pulsed Nd:YAG laser, typically used for vascular conditions, combines collagen stimulation with the ability to reduce the redness of fresh marks. In a comparative study of 30 women with symmetrical stretch marks treated on both sides with different lasers, the Nd:YAG laser produced significantly better clinical results. The average width of treated marks dropped from 1.47 to 0.50 (measured in standardized units), and length decreased from 2.07 to 0.65. Patient satisfaction scores were also significantly higher for this laser.
Fractional CO2 lasers, which create microscopic channels in the skin to trigger deep repair, are more commonly used for older, white stretch marks. They stimulate both new collagen formation and elastin regeneration. In the same study, the CO2 laser reduced mark width from 1.73 to 1.00 and length from 2.07 to 1.25. While less dramatic than the Nd:YAG results, these improvements were still meaningful, and this laser type remains a strong option for mature marks that no longer respond to topical treatments.
A typical laser treatment course involves three sessions spaced about three weeks apart. Most people begin to see visible changes within four to six weeks as new collagen forms, with continued improvement over three to six months.
Microneedling
Microneedling uses a device with tiny needles to create controlled micro-injuries in the skin. This triggers the same wound-healing response that lasers target: new collagen and elastin production. It’s less expensive than laser therapy and can be effective on both newer and older marks.
Clinical protocols typically involve three sessions spaced four weeks apart. The device is applied until uniform pinpoint bleeding appears on the surface, which signals that the needles have reached the right depth in the dermis. Results develop gradually over the weeks following each session as the skin remodels.
Some clinics combine microneedling with platelet-rich plasma (PRP), drawn from your own blood, to potentially enhance the healing response. Research on this combination is still developing, but the microneedling component alone has established evidence for improving stretch mark texture and appearance.
Chemical Peels
Professional-grade glycolic acid peels use concentrations between 20% and 70%, applied for varying durations depending on the desired depth. A very superficial peel might use 30 to 50% for one to two minutes, while a medium-depth peel could use 70% for up to 15 minutes. These peels remove the outer layer of skin and stimulate turnover in the layers beneath, gradually improving the texture and color of stretch marks.
Chemical peels tend to work best as part of a treatment plan rather than a standalone solution. They’re often combined with topical retinoids or microneedling for better results.
What’s Safe During Pregnancy
Since many stretch marks develop during pregnancy, timing matters. Retinoids (tretinoin and its relatives) are off-limits during pregnancy and breastfeeding due to potential risks to the baby. Lasers and chemical peels are also generally avoided during this period.
Topical creams are the main option considered safe for use during pregnancy. Products containing Centella asiatica have the strongest prevention evidence and are widely used. Keeping the skin well-moisturized with simple, fragrance-free creams may also help reduce the severity of marks as they form, even if it doesn’t fully prevent them. The key is consistent daily application starting early in the second trimester, when stretching accelerates.
Realistic Expectations
No treatment returns stretch-marked skin to its original state. The goal is reduction in visibility: narrower marks, less contrast with surrounding skin, improved texture. Red stretch marks respond better and faster than white ones because the skin is still actively remodeling. Once marks have turned white and the collagen has flattened into scar-like tissue, improvements are more modest and require more aggressive treatments like lasers or microneedling.
For topical treatments, plan on several months of consistent use before judging results. For professional procedures, most patients notice visible improvement within three to six months, with the full effect continuing to develop as collagen remodels. Starting treatment early, while marks are still red or purple, consistently produces the best outcomes across every method.
