Stretch Marks and Scars: What Actually Fades Them (and What's Wishful Thinking)
The cream aisle promises to 'erase' both. The biology says timing beats ingredients — and the honest ceiling is lower than the before-and-afters suggest.
Read the preview
From the DermApproved blog, in Skin Concerns: stretch marks and scars — and the whole aisle of creams promising to erase both. Here's the uncomfortable truth the before-and-afters quietly skip. The single biggest thing standing between you and real results isn't an ingredient at all. It's timing. Your marks turn a certain color, and when they do, the treatment window slams shut — and after that, most of what you can buy does almost nothing. So which topicals actually earn their place on the shelf? Which boring, unglamorous option beats the famous ingredient everyone reaches for first? And where, honestly, is the ceiling on those pricey in-office procedures that promise a blank slate — because it's lower than the marketing wants you to think. There's also one beloved remedy that's time to finally retire. We sort the genuine fades from the pure wishful thinking — at dermapproved.com/blog.
The color of the mark is the whole story
Before you spend a cent, look at the mark and ask one question: what color is it? That single observation predicts your results better than any ingredient on any label. Stretch marks arrive in two acts. The first, striae rubrae, are the fresh ones — red, pink, or purplish, sometimes slightly raised, occasionally itchy. Underneath, the skin is still inflamed and biologically busy; the dermis is remodeling, blood vessels are dilated, and fibroblasts are active. The second act, striae albae, are the mature ones — pale, white or silvery, flattened or slightly sunken, with the collagen and elastin already reorganized into a thin, scar-like band. They are, functionally, settled scar tissue.
This matters because almost every treatment that works, works by nudging that early remodeling process. Once a mark has gone white and quiet, there is far less to nudge. A 2015 review in the Journal of the European Academy of Dermatology and Venereology put it plainly: topical treatments are useful for striae rubrae and of limited value for striae albae. So the most important 'ingredient' is calendar time — catching a mark while it's still red is worth more than any hero molecule you can buy afterward. The same red-versus-pale logic applies to scars: a scar that is still pink and firming up is more treatable than one that has been flat and pale for a decade.
What topical retinoids actually do — and don't
Retinoids are the one topical class with genuine, if modest, evidence for early stretch marks. The mechanism is real: tretinoin drives fibroblasts to lay down more type I collagen, and in fresh striae that extra collagen can partially rebuild the thinned dermis. In a randomized trial cited in that JEADV review, tretinoin 0.1% used daily produced roughly a 20% reduction in the length of stretch marks over about three months. That is a real effect — and also a useful reality check. Twenty percent shorter is visible improvement, not disappearance, and it required a prescription-strength concentration on marks that were still red.
On white, mature striae, the same review found tretinoin of limited value, and one lower-strength study showed no meaningful benefit over placebo. So the honest framing is: a retinoid is worth trying early, on fresh marks, with patience measured in months. A gentle over-the-counter option like Cocokind Advanced Retinol Gel 0.5% or the buffered The Ordinary Granactive Retinoid 2% Emulsion can start the process on the face or décolleté, while a body-scaled formula such as Gold Bond Age Renew Retinol Overnight Lotion covers larger areas like hips and thighs. One caveat that isn't optional: topical retinoids are not recommended during pregnancy, which is exactly when many stretch marks appear — so for pregnancy-related striae, retinoids wait until after. If you're new to the ingredient, easing in via a slow schedule beats a fast flare that makes you quit.
Silicone: the boring winner for raised scars
Scars and stretch marks aren't the same tissue, and raised scars — hypertrophic scars and, at the aggressive end, keloids — have their own best-evidenced at-home tool: silicone. Not a plant oil, not vitamin E (which has notably weak scar data), but plain medical-grade silicone, either as a soft sheet worn over the scar or a self-drying gel painted on. A 2020 systematic review and meta-analysis in the International Wound Journal, pooling randomized trials, found that topical silicone gel significantly improved scar pigmentation, height, and pliability compared with no treatment. The leading theory is that silicone hydrates and occludes the scar, normalizing the signals that tell fibroblasts to keep overproducing collagen.
Two honest caveats keep this in perspective. First, the same body of evidence is often rated as moderate-to-low quality, with several trials at meaningful risk of bias — silicone helps, but the effect is measured in scar-scale points, not erasure. Second, it demands consistency most people underestimate: silicone works when it's worn or applied daily for months, ideally starting once a wound has fully closed. For a new surgical or injury scar, that early, relentless window is where silicone earns its keep. For an old, flat, faded scar, it does very little — again, the treatable moment is early.
When you graduate to procedures
If topicals are the opening move, in-office procedures are where the more dramatic (and more expensive) gains live — because they physically restart collagen remodeling instead of merely coaxing it. Microneedling creates thousands of controlled micro-injuries that trigger a wound-healing cascade and new collagen deposition. A 2021 systematic review of randomized trials in the International Wound Journal concluded microneedling is effective and well-tolerated for atrophic scars, with visible improvement often appearing after around three sessions and only mild, temporary side effects like redness and swelling. Fractional and pulsed-dye lasers add another lever: pulsed-dye targets the redness in fresh scars and striae rubrae, while fractional resurfacing rebuilds texture in atrophic scars and white striae. Radiofrequency microneedling combines the needle injury with deep heat.
Here is the ceiling, stated honestly. These procedures improve; they do not erase. Reviews consistently report partial improvement — better color, better texture, a mark that's harder to notice — across multiple sessions, not a blank slate. Results are better on fresh, red marks (that theme again), better on some skin tones and scar types than others, and carry real considerations: cost, downtime, and a genuine risk of post-inflammatory hyperpigmentation in deeper skin tones if the settings or aftercare are wrong. A dermatologist matching the device to your specific mark, color, and skin type is doing something no cream can.
Texture versus color, and the myths worth dropping
A useful mental split when you set expectations: are you fighting texture or color? Texture problems — a raised scar, a sunken acne scar, the thinned channel of a stretch mark — respond mostly to collagen-building interventions like retinoids and needling. Color problems — the red of a fresh scar, the brown of a healed one, the stark white of an old stretch mark — are a pigment-and-vascular story that responds to different tools, from pulsed-dye laser for redness to sun protection and pigment-focused care for brown marks. Confusing the two is why people apply a brightening serum to a raised scar for months and see nothing: they treated color on a texture problem.
Which clears the ground for the myths. No oil 'dissolves' scar tissue or refills a stretch mark; the popular botanical blends mostly moisturize, which improves comfort and slightly softens appearance but doesn't remodel dermis. Vitamin E, despite its reputation, has repeatedly failed to outperform plain moisturizer for scars in controlled work and can even cause contact dermatitis. And 'preventing' stretch marks entirely is largely outside your control — genetics, rapid growth, and hormones drive them more than any cream, though keeping skin supple and moisturized is a reasonable, low-stakes bet. The empowering version of all this: fade what's fresh, protect it from the sun, treat texture and color as separate jobs, and let go of the fantasy that anything in a jar makes a mature mark disappear. If you want to sanity-check a product's claims against what its formula can actually do, run the label through the [ingredient-decoder] and patch new actives before you commit.

Frequently asked
Can stretch marks be removed completely?
No topical or procedure reliably erases a stretch mark. Fresh red or purple marks (striae rubrae) can be meaningfully faded with retinoids, microneedling, or laser, while old white marks (striae albae) respond much less. Realistic goals are improvement in color and texture, not disappearance.
Do retinoids work on old white stretch marks?
Barely. The evidence for tretinoin is concentrated in early, still-red stretch marks, where it modestly shortens and softens them by boosting collagen. On mature white striae, reviews found it of limited value, with one study showing no benefit over placebo. Timing is everything — the redder the mark, the better retinoids work.
Is silicone gel or vitamin E better for scars?
Silicone gel and sheets have far stronger evidence than vitamin E. A 2020 meta-analysis found topical silicone improved scar pigmentation, height, and pliability, whereas vitamin E has repeatedly failed to beat plain moisturizer in controlled studies and can trigger contact dermatitis in some people. For a raised scar, choose silicone.
How many microneedling sessions do scars need?
Randomized trials show visible improvement in atrophic scars often begins around three sessions, but most protocols run several treatments spaced weeks apart. Microneedling improves scars rather than erasing them, and results build gradually. A dermatologist can tailor depth and session count to your scar type and skin tone to reduce the risk of pigmentation.
Why do stretch marks fade on their own but never fully disappear?
Fresh stretch marks naturally lose their red or purple color as inflammation resolves and blood vessels settle, which is why they lighten over months. But the underlying dermis stays thinned and reorganized as scar-like tissue, so the mark remains visible as a pale line. Treatment can improve that residual texture and color, not undo it.
