You finally did it. You hit the goal weight, the scale is cooperating, and you feel lighter than you have in years. But then you look in the mirror and notice those jagged, silvery or reddish lines are still hanging around like uninvited guests at a party. It's frustrating. Honestly, it feels a bit like a bait-and-switch. You were promised a "new you," but these marks—striae, if we’re being fancy—seem determined to remind you of the "old you."
So, will stretch marks go away after weight loss?
The short answer is no. Not entirely. They don't just pack up and leave because your jeans size changed. But there is a lot of nuance here that most "fitspo" influencers won't tell you because it's easier to sell a cream than to explain skin histology.
The Science of Why They Stick Around
Think of your skin like a high-quality rubber band. It’s incredibly resilient. It stretches and snaps back thousands of times. However, if you pull that rubber band too far for too long, the internal fibers start to fray. Eventually, the rubber band develops tiny micro-tears and loses its "snap."
Your skin works the same way. When you gain weight, the dermis (the middle layer of your skin) stretches to accommodate the growth. If the stretching happens faster than the skin can produce collagen to support it, the fibers break. This creates a scar. That is exactly what a stretch mark is: a scar that formed from the inside out.
Because stretch marks are permanent structural changes to the dermal layer, losing weight doesn't "fix" the tear. In fact, sometimes weight loss makes them look more prominent. When the skin is taut and full, the marks might be stretched thin. Once you lose the volume underneath, the skin becomes more relaxed or even saggy, which can make the texture of the stretch marks appear deeper or more crinkled.

The Color Phase Matters More Than You Think
If you’re looking at your skin right now, the color of your marks tells a story about how much "improvement" you can expect.
Striae Rubra (The Red/Purple Ones)
If your marks are red, purple, or even a deep pink, that’s actually good news in the context of treatment. This color indicates that blood vessels are still present and active in the area. The skin is still trying to heal. At this stage, topical treatments like tretinoin (Retin-A) or laser therapies are significantly more effective. Dr. Arash Akhavan, a noted dermatologist in New York, often points out that catching them in this vascular stage is the "golden window" for intervention.
Striae Alba (The White/Silver Ones)
These are the older, "mature" marks. They’ve faded to a white or silvery hue because the blood vessels have constricted. They are essentially old scars. While you can improve the texture of these, getting them to "go away" is virtually impossible without surgical intervention. They’re part of your skin’s architecture now.
Can You Drink or Eat Your Way Out of It?
We’ve all seen the ads for collagen peptides and "skin-tightening" smoothies. It would be great if a scoop of powder could knit your dermis back together.
But it doesn't work like that.
While staying hydrated and eating a diet rich in Vitamin C, Zinc, and protein supports overall skin health, it won't erase existing scars. Vitamin C is a co-factor for collagen synthesis—basically the "glue" that helps your body build skin—but your body prioritizes where that collagen goes. It’s going to fix a leaky gut or a damaged tendon long before it decides to "beautify" a stretch mark on your stomach.
That said, hydration is non-negotiable. Dehydrated skin loses elasticity. If you are dehydrated, your stretch marks will look more shriveled and noticeable. Drink your water, but don't expect it to be a magic eraser.
What Actually Works (and What Is a Total Scam)
Let's get real about the stuff people try to sell you.
Cocoa Butter and Bio-Oil: Honestly? They’re great moisturizers. They make your skin feel soft. But study after study, including research published in the British Journal of Dermatology, has shown that these don't actually prevent or remove stretch marks. They just don't penetrate deep enough into the dermis to repair the torn fibers. If you like the smell, use them. Just don't expect a miracle.
Retinoids: This is the heavy hitter. Prescription-strength Tretinoin has some evidence backing its ability to improve the appearance of new (red) stretch marks. It works by irritating the skin just enough to jumpstart collagen production. You can’t use it if you’re pregnant or nursing, though, so keep that in mind.
Microneedling: This is becoming the gold standard for many. By creating thousands of tiny "micro-injuries" with needles, you force the body to flood the area with healing factors. It’s effective for both red and white marks because it addresses the texture, not just the color.

Laser Therapy: Laser treatments like Pulse Dye Laser (for red marks) or Fractional CO2 (for white marks) can be life-changing for some. They are also expensive. You’re looking at hundreds, if not thousands, of dollars for a series of sessions.
The Role of Genetics
You could do everything "right." You could lose weight slowly, stay hydrated, and slather yourself in every oil known to man. And you might still end up with more stretch marks than someone who lost 100 pounds overnight and lived on soda.
Genetics are the silent dictator here.
Some people have skin that is naturally more rich in elastin—the protein that allows skin to stretch and bounce back. Others have a genetic predisposition toward "stiffer" skin. If your mom or dad has stretch marks, you likely will too. It’s not a failure of your diet or your skincare routine; it’s just your biological blueprint.
When Loose Skin Makes It Look Worse
There’s a specific phenomenon that happens after significant weight loss. As the fat cells shrink, the skin that was once stretched over them becomes "extra." This loose skin often bunches up, creating a "crepey" texture.
In this scenario, will stretch marks go away after weight loss? No, and they might actually look like "ripples" in the loose skin.
For people who have lost a massive amount of weight (think 50 to 100+ pounds), the only way to truly remove those stretch marks is through skin removal surgery, like a tummy tuck (abdominoplasty) or a body lift. During these procedures, the surgeon literally cuts away the skin that contains the majority of the stretch marks. It’s a drastic measure, but for many, it’s the only way to see a smooth surface again.
Is "Acceptance" Just a Cop-Out?
It’s trendy to call them "tiger stripes" or "lightning bolts." For some, that helps. For others, it feels like toxic positivity.
It is okay to be annoyed by them. It is also okay to realize that they are a byproduct of a body that has changed, grown, or shrunk. They are evidence of a transition.
The reality is that almost everyone has them. Even athletes. Even "thin" people. Even men. About 80% of people have stretch marks somewhere on their body. You’re noticing yours more because you’re focused on your transformation, but the rest of the world likely isn't even looking.
Actionable Steps To Improve Your Skin Post-Weight Loss
If you’re done with the "wait and see" approach and want to take action, here is the most logical path forward. Skip the gimmicks and follow the science.
- Audit your current marks: Are they red or white? If they’re red, go see a dermatologist now. You have a clock ticking on the most effective treatment window.
- Focus on Tretinoin: Ask your doctor about a prescription retinoid. It is the only topical treatment with significant clinical backing for remodeling skin tissue.
- Prioritize strength training: Building muscle underneath the skin won't remove the stretch marks, but it provides a firmer "foundation." This can help the skin look tighter and reduce the sagging that makes marks look more prominent.
- Check your Zinc and Vitamin C intake: Don't just take supplements blindly. Eat more bell peppers, citrus, pumpkin seeds, and lean meats. These provide the raw materials for skin repair.
- Moisturize for texture, not "erasure": Use a thick emollient like hyaluronic acid or ceramides. It won't make the marks disappear, but it will plump the surrounding skin, making the scars less "sunken" and obvious.
- Consider Microneedling: If you have the budget, look into professional microneedling (not the cheap rollers you use at home, which can cause more tearing). A series of 3-6 sessions can significantly level out the "divots" in the skin.
The truth is that your skin has a memory. Weight loss is a massive achievement for your heart, your joints, and your longevity. If the "cost" of that health is a few silver lines, most doctors—and eventually, most people—would say that’s a fair trade.
