Stretch marks fade significantly over time on their own, but you can speed that process with the right topical ingredients, in-office procedures, or a combination of both. The single biggest factor in how well any treatment works is timing: newer, reddish-pink stretch marks respond far better than older, white or silver ones. Understanding that distinction will save you money and frustration.
Why Stretch Marks Form
Your skin gets its structure and bounce from two proteins: collagen and elastin. When skin stretches or shrinks faster than those fibers can keep up, they rupture. The visible scar left behind is a stretch mark. This is why they commonly appear during pregnancy, growth spurts, rapid weight changes, and muscle-building phases.
Stress hormones play a role too. Your body’s cortisone levels directly affect how elastic collagen is. When cortisone production is high, collagen becomes stiffer and more prone to tearing. That’s one reason stretch marks sometimes appear during periods of intense emotional or physical stress, even without dramatic body size changes.
New Red Marks vs. Old White Marks
Stretch marks go through two distinct stages, and recognizing which stage yours are in determines what treatment is worth trying. Early-stage marks (called striae rubra) are smooth, slightly raised, and red or purple. They still have active blood flow and some intact structure, which makes them much more responsive to treatment.
Over months to years, marks transition into their permanent stage (striae alba). These appear pale, flat, and slightly wrinkled, with thinned skin and less pigment. A systematic review in Dermatologic Surgery confirmed that white stretch marks are considerably harder to treat and less responsive to laser and light therapies. That doesn’t mean nothing works on old marks, but your expectations and approach should differ.
Topical Treatments That Have Evidence
Tretinoin (Prescription Retinoid)
Tretinoin is one of the few topical ingredients with clinical trial data behind it for stretch marks. A trial using 0.1% tretinoin cream on early red stretch marks showed improvement in their appearance. However, at a lower concentration of 0.025%, applied daily for seven months to pregnancy-related marks, it was ineffective. The takeaway: tretinoin may help, but only at higher concentrations and only on newer marks. It’s a prescription product, so you’d need to talk to a dermatologist.
One critical caveat: retinoids of any kind, including tretinoin and over-the-counter retinol, must not be used during pregnancy or breastfeeding. Vitamin A derivatives carry known risks for fetal development.
Centella Asiatica Extract
Centella asiatica (also called gotu kola or cica) is one of the more promising botanical options. Lab research shows its active compounds stimulate the growth of skin-rebuilding cells, increase collagen fiber density by 49%, and boost elastin production by 37% in stretch-marked skin samples. It also reduces the activity of enzymes that break down collagen. A small controlled trial found that a cream containing Centella asiatica extract significantly reduced the development of new stretch marks compared to a placebo, though the study was small and the results should be interpreted cautiously.
Look for products listing Centella asiatica extract, asiaticoside, or madecassoside in the first several ingredients. This is one of the few botanicals with a plausible mechanism and at least preliminary clinical support.
What Doesn’t Work
Cocoa butter, olive oil, and vitamin E are among the most commonly purchased stretch mark remedies. In a Cochrane review of six controlled trials involving 800 women, none of these ingredients showed a significant difference in preventing or reducing stretch marks compared to placebo or no treatment. They’re fine moisturizers and won’t hurt your skin, but don’t expect them to change your stretch marks.
Hyaluronic acid, despite its popularity in skincare, has only weak and inconclusive evidence for stretch mark prevention. It may support general skin hydration, but there isn’t enough data to recommend it specifically for this purpose.
In-Office Procedures
Microneedling
Microneedling uses tiny needles to create controlled micro-injuries in the skin, triggering your body’s natural repair process and new collagen production. In a systematic review, mechanical microneedling produced at least some degree of improvement in 100% of white stretch mark cases studied. It won’t erase marks completely, but it’s one of the most consistent performers for older, stubborn marks. Most people need a series of three to six sessions, spaced about four weeks apart.
Fractional CO2 Laser
Fractional CO2 lasers showed the strongest results overall for both repigmenting white stretch marks and stimulating new collagen and elastin. In reviewed studies, CO2 laser achieved a complete response in 100% of treated red stretch marks and a 14% complete response rate for white marks, which is notable given how resistant white marks are to any treatment. The combination of fractional laser with microneedling appears to be especially effective.
IPL and Pulsed Dye Laser for Red Marks
For newer red marks, intense pulsed light (IPL) and pulsed dye laser (PDL) both target the blood vessels that give early stretch marks their color. IPL showed improvement in 94% of red mark cases, compared to 77% for PDL. These options work best when marks are still in the early inflammatory stage.
Skin Tone Matters for Laser Safety
Laser treatments carry real risks for people with medium to dark skin tones. A study testing both pulsed dye laser and CO2 laser on patients with darker skin found no improvement in some cases and significant hyperpigmentation (dark patches) in others. If you have a deeper skin tone, discuss these risks carefully with a dermatologist before committing to laser treatment. Microneedling is generally considered a safer alternative for darker skin.
How Long Results Take
Topical treatments require patience. Most products need a minimum of 12 weeks of consistent daily use before you can fairly judge results. Some people notice subtle changes in texture or color around weeks two to four, but meaningful improvement typically takes three months or longer. For prescription tretinoin, studies evaluated results at similar timeframes.
In-office procedures follow a different timeline. You’ll often see gradual improvement between sessions, with full results visible a few months after your final treatment as new collagen continues to form beneath the surface. Microneedling and laser sessions are typically scheduled four to six weeks apart, so a full course of treatment can span three to six months.
Practical Steps to Start
If your marks are still red or purple, you’re in the best window for treatment. Start with a Centella asiatica cream applied daily, and if your marks are significant enough to warrant prescription treatment, ask a dermatologist about tretinoin at 0.1% concentration. For faster results, IPL or pulsed dye laser can target the redness directly.
If your marks are already white or silver, topical creams alone are unlikely to produce dramatic changes. Your best options are microneedling, fractional CO2 laser, or a combination of both. A Centella asiatica product can still support skin repair between sessions, but the heavy lifting will come from procedures that physically remodel the deeper layers of skin.
Regardless of stage, keeping your skin well-hydrated supports its overall elasticity and can improve the texture of stretch marks over time. Skip the expensive cocoa butter marketed for stretch marks and invest that money in ingredients with actual evidence, or save it toward an in-office treatment that will make a more noticeable difference.
