Why Stretch Marks Tan Differently
If you've ever noticed that your stretch marks stay stubbornly lighter (or occasionally darker) than your surrounding skin when you tan, you're not imagining it. There's a real biological reason for this, and once you understand it, you can work with it instead of stressing about it.
Stretch marks are scar tissue. When skin stretches rapidly (growth spurts, weight changes, pregnancy), the dermis layer tears and heals with scar tissue that has fewer melanocytes — the cells responsible for producing melanin. Fewer melanocytes means less melanin production, which means less tanning. So while your normal skin is happily producing pigment in the sun, your stretch marks are sitting there unable to keep up.
New vs. Old Stretch Marks
Fresh stretch marks (the red, pink, or purple ones) can actually darken temporarily in the sun because the blood vessels underneath are still active and can become more visible with UV exposure. This is different from actual tanning — it's vascular, not melanin. These newer marks might look darker than your tan, which is the opposite problem.
Old stretch marks (the white, silvery ones) are the classic "won't tan" type. The scar tissue is fully formed, melanocytes are minimal, and no amount of sun exposure is going to make them match your surrounding skin. This is just the reality of how healed scar tissue works.
Can You Make Stretch Marks Tan?
Let's be honest: you cannot make white/silver stretch marks tan to match surrounding skin through sun exposure alone. The melanocytes aren't there to produce the pigment. More sun exposure will just make the surrounding skin darker, increasing the contrast and making stretch marks more visible.
This is actually important to understand because some people try to "burn through" the contrast by tanning more intensely. That doesn't work. It makes things worse. More UV = darker surrounding skin = more visible stretch marks. Plus, you're now overexposing yourself to UV for no benefit.
Self-Tanner Is the Real Solution
The best way to minimize stretch mark contrast is self-tanner applied directly to the stretch marks. Since self-tanner works by reacting with dead skin cells (not melanocytes), it can color stretch marks that UV can't. Here's how to do it effectively:
Exfoliate first. Gently exfoliate the area to remove dead skin and create an even surface. Stretch marks can have different textures, so this step helps the self-tanner go on smoothly. Apply with precision. Use a small brush, cotton swab, or your fingertip to apply self-tanner directly to the stretch marks. You want to target just the marks, not the surrounding skin. Build gradually. Start with one thin layer and check the color after it develops (6-8 hours). Add another layer if needed. It's much easier to add more than to fix going too dark. Match carefully. You're trying to match the color of your tanned skin, so do this after your natural tan is established, not before.
Gradual Tanners for Overall Blending
If you don't want to do the precision application thing, a gradual self-tanner applied all over the area (stretch marks and surrounding skin) can help too. It won't perfectly match everything, but it reduces the contrast by adding color to the stretch marks while only slightly darkening the surrounding skin (which is limited because it's already tanned).
Apply the gradual tanner every other day and the stretch marks will slowly build color. After 3-4 applications, you should see a noticeable reduction in contrast. It won't be invisible, but it'll be much less obvious.
Moisturize Religiously
Stretch marks show up more when skin is dry. Dry, flaky skin scatters light differently and makes texture differences more visible. Keeping your skin deeply moisturized minimizes the visual appearance of stretch marks, tanned or not.
Use a rich body butter or cream on stretch mark areas twice daily. Look for ingredients like cocoa butter, shea butter, hyaluronic acid, or vitamin E. These won't make stretch marks disappear, but they'll make your skin smoother and healthier overall, which reduces how much the marks stand out.
Accepting the Reality
Here's the thing nobody says enough: stretch marks are incredibly common and totally normal. Studies suggest that up to 80% of people have them. They happen during puberty, growth spurts, weight changes, and muscle gain. They're not a flaw — they're literally just evidence that your body has grown and changed, which is... life.
A tan looks beautiful whether you have stretch marks or not. From a normal viewing distance, most stretch marks are barely noticeable to other people. We always see our own skin imperfections more than anyone else does. So yes, use self-tanner to blend if you want. But also know that you look great either way.
Rock your tan. Rock your stretch marks. They're both part of you.

Professional Treatments
Microneedling: Over 3-6 sessions, scar tissue remodels. Some report stretch marks tanning more evenly after treatment.
Laser treatments: Fractional laser improves texture and color by triggering collagen production.
Retinoid creams: Improve newer stretch marks but make skin extremely sun-sensitive — use only in off-season.
Stretch Marks by Body Area
Hips and outer thighs: Most common location. Surrounding skin tans easily, increasing contrast. Apply self-tanner to marks after each session.
Inner thighs: Less visible — low-priority concern.
Breasts and chest: Thin skin makes marks more visible. Gradual self-tanner applied with a finger works well.
Back: Hard to treat solo. Ask a friend for precision self-tanner. Honestly, barely visible to other people.
The Confidence Perspective
You do not need to avoid tanning because of stretch marks. Millions tan with them every summer and look incredible. The contrast you see up close in your mirror is NOT what others see at the beach. Tan however you are comfortable. Use self-tanner tricks if they boost confidence. Use our tanning calculator and skin type quiz. Then enjoy the sun.
Makeup and Temporary Camouflage for Events
If you have an event — beach party, wedding, vacation photos — and want your stretch marks to blend in for a few hours, temporary makeup camouflage is an option that works surprisingly well:
Body foundation or concealer: Products like Dermablend Leg and Body Makeup or KVD Good Apple Full-Coverage Body Foundation are designed for exactly this purpose. They are waterproof, long-wearing, and provide full coverage that can make stretch marks virtually invisible for 12+ hours. Apply with a brush or sponge, blend edges carefully, and set with a translucent powder.
Self-tanner as camouflage: A strategic application of medium-shade self-tanner specifically on the stretch marks 24-48 hours before an event can significantly reduce visibility. The DHA darkens the pale scar tissue to closer to your tanned skin's shade. This is not instant but lasts much longer than makeup — typically 3-5 days.
Shimmer lotion as a distraction: A subtle shimmer body lotion on the surrounding tanned skin draws the eye to the overall glow rather than any specific marks. The reflective particles in shimmer lotions scatter light in a way that makes texture differences (like stretch marks) less noticeable. This is the simplest, fastest option and works well for casual events.
Combine approaches for maximum effect: self-tanner on the marks 2 days before, shimmer lotion on the surrounding skin the day of, and body foundation as spot treatment if needed. At normal viewing distance, even prominent stretch marks become virtually invisible with this layered approach.
And remember — these are options if YOU want them, not obligations. Most people at any event are far too focused on having fun to examine your skin's texture. The camouflage is for your confidence, not for anyone else's benefit.
Stretch Marks and Different Self-Tanner Types
Not all self-tanners work equally well on stretch marks. The texture of scar tissue affects how DHA absorbs and develops:
Gradual lotions (Jergens, St. Tropez Gradual) are the safest choice. They build slowly and you can see how the color develops on the stretch mark versus surrounding skin with each application. If the mark is absorbing too much or too little, you adjust on the next application. Very forgiving.
Mousse or foam self-tanners can work but require more careful application. The lighter texture can collect in the textured surface of stretch marks, creating slightly darker lines. If you use a mousse, apply with a mitt in very thin, smooth strokes over the stretch mark area.
Spray self-tanners are tricky on stretch marks because the spray can deposit unevenly on textured skin. If you use a spray, apply it to a mitt first and then apply the mitt to the stretch mark area rather than spraying directly.
Tanning drops (Isle of Paradise, Tan-Luxe) are excellent for precision work. Mix 2-3 drops into a small amount of moisturizer and apply specifically to the stretch marks with your fingertip. The moisturizer base helps the DHA distribute evenly across the scar tissue. This is the most controlled method available.
Whichever product type you choose, always exfoliate the stretch mark area gently before application. The texture of scar tissue holds dead skin differently than normal skin, and this uneven cell surface is the main cause of uneven DHA development. A smooth surface going in means a smoother result coming out.
