You’ve seen them. Maybe you call them battle scars, or maybe you use the more poetic term: tiger stripes stretch marks. They show up uninvited after a growth spurt, a pregnancy, or a season of heavy lifting at the gym. Honestly, most people have them. In fact, some studies suggest up to 90% of women and a massive chunk of men carry these narrow streaks somewhere on their bodies.
They aren't a medical emergency. They don't hurt. But the psychology behind them? That’s a whole different story.
The skin is an incredible organ, but it has its limits. When the body expands faster than the skin’s elastic fibers can keep up with, things start to snap—metaphorically and structurally. It’s like pulling a piece of spandex past its breaking point. It doesn't just go back to the way it was. Instead, you get these linear bands of crinkly, off-color skin. They start out red or purple (striae rubra) and eventually fade into a silvery, white, or translucent shade (striae alba).
The Biological Truth Behind Tiger Stripes Stretch Marks
To understand why your skin does this, you have to look at the dermis. This is the middle layer of your skin. It’s packed with collagen and elastin—the stuff that keeps you looking "bouncy."
When your body grows rapidly, the dermis literally tears.
It sounds violent, but it's a slow-motion process. Dr. Eric Bernstein, a clinical professor at the University of Pennsylvania School of Medicine, has often noted that stretch marks are essentially a form of scarring. When that dermal layer thins out, the blood vessels underneath show through, which is why new marks look so angry and red. Over time, those vessels contract, the fat underneath becomes more visible, and the mark turns white.
It's not just about "stretching," though. Hormones play a huge role. If you have high levels of cortisol in your system—whether from stress or medications like prednisone—your skin loses its elasticity. Cortisol actually prevents fibroblasts from producing the collagen and elastin fibers needed to keep skin tight. This is why some people get tiger stripes stretch marks even without massive weight changes, while others can go through a full twin pregnancy and come out with skin as smooth as glass. Genetics is the silent hand holding the deck. If your mom has them, you're likely getting them too.
Why Do They Happen?
It's rarely just one thing. Most of the time, it's a "perfect storm" of biology and lifestyle.
- Puberty: This is the big one. Rapid growth in height or the widening of hips and breasts creates tension the skin wasn't ready for.
- Pregnancy: The skin on the abdomen can stretch to several times its original size in just a few months.
- Bodybuilding: Quick muscle hypertrophy, especially in the shoulders and biceps, often leaves "tiger stripes" right where the muscle meets the armpit.
- Medical Conditions: Issues like Cushing’s syndrome or Marfan syndrome affect how the body produces skin tissue, making stretch marks much more likely and often much wider.
Can You Actually Get Rid of Them?
Let’s be real for a second. The skincare industry is worth billions because it sells hope in a jar. If you go to a drugstore, you’ll see dozens of creams claiming to "erase" tiger stripes stretch marks.
Spoiler: They won't.
Once the dermis is torn, a topical cream isn't going to "stitch" it back together. Most of these products just hydrate the top layer (the epidermis), which makes the marks look slightly less noticeable because the skin is plumped up with moisture. But the scar? It’s still there.
There is some evidence for Tretinoin (Retin-A). If you catch the marks while they are still red or purple, a prescription-strength retinoid can help rebuild some collagen. However, if you're pregnant or breastfeeding, you can't touch the stuff—it’s a big no-go for fetal safety. Also, it does absolutely nothing for older, white marks.
The Heavy Hitters: Lasers and Microneedling
If you’re serious about changing the texture of your skin, you have to go deeper than a lotion.
- Vascular Lasers: Specifically the Pulse Dye Laser (PDL). This is gold standard for new, red marks. It targets the blood vessels to take the "fire" out of the color.
- Fractional CO2 Lasers: These create microscopic holes in the skin to trigger a massive healing response. It’s basically controlled damage to force the body to make new collagen.
- Microneedling: This involves tiny needles puncturing the skin. According to a study in the Journal of Dermatologic Surgery, microneedling can be just as effective as lasers for certain skin types, with less downtime. It’s particularly useful for "filling in" the depressed, sunken texture of older marks.
- Radiofrequency (RF): Often combined with microneedling, RF sends heat deep into the tissue to tighten things up.
None of these are "one and done." You’re looking at three to six sessions. And even then, "removal" is a strong word. "Significant improvement" is a better way to phrase it. You might get a 50% to 70% reduction in visibility, but your skin will never be exactly what it was before the tear.
The Myth of Cocoa Butter
We’ve all heard it. "Just rub cocoa butter on your belly and you won't get stretch marks."
Actually, the British Journal of Dermatology published a study that followed hundreds of women and found no significant difference between those who used cocoa butter and those who used nothing. The same goes for olive oil.

If you want to use them because they smell good and stop the itching that comes with stretching skin, go for it. Just don't expect them to be a shield. If your skin is genetically predisposed to tearing, it's going to tear regardless of how much grease you put on it.
The only "preventative" that has some decent data behind it is Centella asiatica (sometimes called Cica or Tiger Grass). A few small trials suggested that creams containing this herb might help increase the skin's tensile strength, but even that isn't a guarantee.
Managing the Mental Side of Tiger Stripes
The name "tiger stripes" didn't come from a marketing boardroom; it came from the body-positivity movement. For a long time, these marks were treated like a flaw to be hidden. But lately, there’s been a shift.
Look at public figures like Chrissy Teigen or Rihanna. They’ve posted unedited photos showing their stretch marks. It’s a move toward "body neutrality"—the idea that your body is a vessel that does things for you, and its appearance is just a byproduct of living.
When you see those marks, you're looking at evidence of your body's history. Maybe it's the history of you becoming a mother. Maybe it's the history of you training until your muscles outgrew your frame. It’s easy to get caught up in the "fix it" mentality, but sometimes the most effective treatment is just a change in perspective.
What You Should Actually Do Now
If you are bothered by your tiger stripes stretch marks, stop buying random oils off Instagram. Here is the realistic path forward.
First, check the color. If they are red or purple, see a dermatologist immediately. This is your "window of opportunity." Prescription retinoids or a few rounds of PDL laser can drastically fade that color before it becomes permanent.
Second, hydrate from the inside. While lotions don't do much for the dermis, staying hydrated helps your skin's overall elasticity. It won't stop a tear, but it makes the healing process more efficient.
Third, manage your expectations. If your marks are already white or silvery, they are essentially "mature" scars. They are harder to treat. If you choose to go the laser route, find a provider who uses a fractional non-ablative laser or Microneedling with Radiofrequency (like Morpheus8 or Vivace). These are the only tools that really move the needle on texture.
Finally, sun protection is non-negotiable. Stretch marks don't tan; they don't have the same pigment-producing cells as your regular skin. If you get a tan, the marks will actually stand out more because they stay white while the surrounding skin gets darker. Use a high-SPF sunscreen to keep the contrast low.

Taking care of your skin is a long game. Whether you decide to treat them or wear them as they are, remember that your skin is doing exactly what it was designed to do: it’s changing to accommodate your life. It isn't broken. It's just a map of where you've been.
