Stretch marks can appear after pregnancy, weight changes, growth spurts, or changes in muscle size. And while they’re completely normal, many people look for inexpensive ways to make them less noticeable.
One popular home remedy claims that crushing aspirin tablets and applying them to the skin can erase stretch marks in just seven days.
But can a common painkiller really make those lines disappear?
There is no scientific evidence that applying aspirin removes stretch marks in seven days—or that it is an effective treatment for stretch marks at all.

1. Why Do Stretch Marks Appear?
Stretch marks, medically known as striae, develop when the skin stretches or shrinks relatively quickly.
This can disrupt collagen and elastin, two important components that help skin maintain its structure.
They commonly appear on the abdomen, thighs, hips, breasts, and upper arms.
Newer stretch marks may look pink, red, purple, or darker than the surrounding skin. Older marks often become lighter and less noticeable.
Although they can fade naturally, they don’t always disappear completely.
2. Why Are People Applying Aspirin to Stretch Marks?
Aspirin contains acetylsalicylic acid, which is chemically related to salicylic acid.
Salicylic acid is used in some skincare products to exfoliate the outer layers of skin.
This has led to the mistaken belief that crushed aspirin can remove stretch marks.
But stretch marks involve changes deeper within the skin—not simply dead skin cells on the surface.
Exfoliating the skin cannot reverse these structural changes.
3. What Happens If You Apply Crushed Aspirin?
Online tutorials sometimes recommend crushing several aspirin tablets and mixing them with water, honey, or oil.
However, aspirin tablets aren’t formulated for topical skincare.
Applying these mixtures can cause:
- Redness and irritation
- Burning or itching
- Dryness and peeling
- Allergic skin reactions
- Dark marks caused by inflammation
Leaving a homemade aspirin mixture on the skin for extended periods may increase irritation.
For these reasons, a crushed aspirin mask is not recommended for treating stretch marks.
4. What Actually Helps Stretch Marks Fade?
Several approaches may improve the appearance of stretch marks, although results vary.
Moisturizers: Regular moisturizing can improve skin comfort and texture, but it hasn’t been shown to erase established stretch marks.
Hyaluronic acid: Some preliminary evidence suggests certain formulations may help newer stretch marks become less noticeable.
Prescription tretinoin: Some studies have found improvements in early stretch marks with consistent use over several months. Tretinoin should not be used during pregnancy, and its use while breastfeeding should be discussed with a clinician.
Dermatological procedures: Microneedling and certain laser treatments may improve the appearance of stretch marks, although they cannot guarantee complete removal.
5. A Gentle Seven-Day Skincare Routine
Although seven days isn’t enough to erase stretch marks, it’s enough to begin a consistent skincare routine.
Simple 7-Day Skin-Care Plan
Repeat daily for one week
- Morning: Wash the area gently with lukewarm water.
- After bathing: Apply a fragrance-free moisturizer containing glycerin, ceramides, or hyaluronic acid.
- During the day: Protect exposed areas from the sun with broad-spectrum SPF 30 or higher.
- Evening: Apply moisturizer again if the skin feels dry or tight.
- Avoid: Harsh scrubs, crushed aspirin, lemon juice, and aggressive exfoliation.
This routine may improve hydration and skin comfort, but it won’t remove stretch marks within a week.
6. Do Natural Oils Help?
Coconut oil, almond oil, and other plant oils are often recommended for stretch marks.
These oils may soften dry skin and reduce moisture loss.
However, there’s insufficient evidence that they can prevent or erase stretch marks.
If you enjoy using a body oil, apply a small amount to intact skin after moisturizing, and stop if irritation develops.
7. When Should You See a Dermatologist?
If stretch marks are new and you want to explore treatment, seeing a dermatologist early may be helpful.
Newer marks sometimes respond better to certain treatments than older ones.
You should also seek medical advice if you develop numerous wide stretch marks suddenly, especially without an obvious cause, or if they’re accompanied by easy bruising, muscle weakness, or other unusual symptoms.
These changes can occasionally be associated with medication effects or hormonal conditions.
The Bottom Line
The aspirin trick may sound like a quick, inexpensive solution, but crushed aspirin has not been proven to remove stretch marks in seven days.
Stretch marks are a common form of skin scarring, and improving their appearance usually takes time.
Gentle skincare can help keep the skin comfortable, while evidence-based dermatological treatments may offer more noticeable improvements.
And remember: stretch marks are normal. Treating them is a personal cosmetic choice, not a medical necessity.
