If you've found a white, slightly pasty or crumbly buildup under your clitoral hood or in the folds between your inner and outer labia, you're looking at something completely ordinary. The medical name is smegma, the same word used for men, and it's one of the most searched "is this normal?" questions about the vulva. It's a mix of shed skin cells, natural oils and moisture that collects wherever skin folds over skin. It isn't an infection, and it isn't a sign you're unclean. It just needs a gentle rinse.
Below: what it is, why it smells, how to clean under the clitoral hood without irritating anything, and how to tell it apart from yeast, lichen sclerosus and clitoral adhesions.
What is the white stuff under the clitoral hood and in the labia folds?
Vulvar skin is packed with sebaceous (oil) glands and sweat glands, especially on the labia (Farage & Maibach, 2006). Like skin anywhere else, it constantly sheds its top layer. On open skin, those cells and oils rub off on underwear. In folds, such as the groove beside the inner labia or the space between the hood (prepuce) and the glans of the clitoris, they stay put, mix with moisture and form a soft white or off-white paste.
How much you get varies from person to person and through life. It tends to build up faster with:
- Heat, sweat and tight or synthetic underwear
- Days without a rinse (gym, travel, illness)
- Arousal fluid, discharge and lube residue drying in the folds
- Larger or more covering labia or clitoral hood, which simply means more folds
What does it smell like?
Fresh buildup barely smells. After a day or two, skin bacteria break down the oils and proteins, and it develops a stale, cheesy or musky odor, much like sweat left in a sock. That smell comes from the skin surface, not from the vagina, so it goes away once the area is rinsed. If the odor is fishy, comes with thin grey discharge or stays after washing, it's more likely coming from inside the vagina. See what BV smells like and why your vagina smells.
How to clean under the clitoral hood and between the labia
Daily gentle cleansing of the vulva is supported by the hygiene research, as long as products don't disrupt the skin or the vaginal microbiome (Chen et al., 2017). In practice:
- Use warm water and your fingers. No washcloth, loofah or scrubbing. Vulvar skin is thinner and more reactive than skin elsewhere.
- Gently retract the hood. Use two fingers to slide the skin above the clitoris up toward your belly, just as far as it moves comfortably. Rinse the groove around the glans. Never force it.
- Part the labia. Rinse the crease between the inner and outer lips, front to back.
- Skip regular soap. Bar soap and scented body wash are alkaline and can leave the area tight, itchy and more irritated. If you want a cleanser, use a fragrance-free one made for intimate skin, on the outside only, never inside the vagina.
- Pat dry. Leftover moisture in the folds is what lets buildup come back.
Once a day is plenty, and many people only need this every other day. Over-washing strips the skin's own lipids and can make the area dry and itchy, which some people then mistake for an infection.
That's why we made WASH: a fragrance-free, prebiotic wash you use instead of soap on the groin, underarms and intimate skin. It's third-party tested for its effect on healthy skin flora, so it cleans without stripping the bacteria you want to keep. More on choosing a cleanser in our guide to intimate washes.
Is it smegma, yeast or something else?
Most white stuff on the vulva falls into one of these:
- Normal buildup: pasty, sits in the folds, wipes or rinses off, no itching or burning, smell gone after washing.
- Yeast infection: thick, clumpy, cottage-cheese discharge coming out of the vagina, with itching, burning, redness or swelling. It doesn't rinse away for good. See UTI vs yeast infection.
- Discharge drying on the skin: normal vaginal discharge can dry into white or yellowish flakes on the labia. Harmless.
- Lichen sclerosus: white, thin, crinkly or shiny skin (not a paste), often very itchy, sometimes with small tears. This needs a doctor's diagnosis and treatment. Don't try to scrub it away.
- Contact irritation: red, stinging skin after a new wipe, pad, soap or lube. See genital dermatitis.
Clitoral adhesions and keratin pearls
Sometimes the hood partly sticks to the glans so it won't retract fully. These are clitoral adhesions, and they're more common than most people think. In a review of vulvoscopy photos from 614 patients at a sexual medicine clinic, 23% had adhesions, and about 14% of those had clitoral pain. Adhesions were associated with a history of sexual pain, yeast infections, UTIs, genital trauma, lichen sclerosus and low free testosterone (Aerts et al., 2018).
When buildup gets trapped under an adhesion, it can harden into small, firm, white or yellow lumps called keratin pearls, or smegmatic pseudocysts. A 2023 review lists these, along with inflammation and infection, as complications of adhesions. It also notes that adhesions are most often studied in women with lichen sclerosus, and that there is no agreed standard of care yet (Sex Med Rev, 2023).
See a gynecologist or a vulvar or sexual medicine specialist if:
- The hood won't pull back, or pulling it back hurts
- You feel a hard bump under the hood that doesn't rinse away
- You have clitoral pain, burning or reduced sensation
- The skin looks white and thin, cracks, or itches constantly
Don't pick at a pearl or try to free an adhesion yourself. Both are handled in-office.
Keeping the area comfortable
A few habits stop buildup from turning into an odor or irritation problem:
- Breathable cotton underwear, and change out of sweaty gym clothes soon after a workout.
- Rinse after sex. Lube, semen and arousal fluid drying in the folds feed the same skin bacteria.
- Pick a lube that won't leave a sticky residue or sting. High-osmolality and glycerin-heavy formulas can irritate delicate tissue (Dezzutti et al., 2012). More in why does lube burn?
- If the hood and labia feel dry, tight or sore (common around menopause, postpartum or on hormonal birth control), moisturize rather than wash more.
For dryness and friction, we use Juicy Balance. It's a water-based intimate moisturizing serum: glycerin-free, propylene-glycol-free and fragrance-free, buffered to pH 4.5–4.9, with an osmolality of about 296 mOsm/kg. It rinses off cleanly and doesn't leave a film in the folds. In our 5-day Juno Bio tester group, Lactobacillus went from 30% to 45% for our postmenopausal tester and from 76% to 96% for a tester aged 26–35 (full results here).

FAQ
Is female smegma normal?
Yes. Everyone with a vulva produces it. The amount depends on your anatomy, sweat, hormones and how often you rinse. It only becomes a problem if it's trapped (adhesions) or comes with itching, pain or a smell that doesn't wash off.
How do I get rid of it for good?
You can't, and you don't need to. Your skin keeps shedding. A daily or every-other-day warm-water rinse under the hood and between the labia keeps it from building up or smelling.
Can I use wipes to clean it?
Occasionally, if they're fragrance-free and alcohol-free. Many wipes contain preservatives and fragrances that irritate vulvar skin. See what to know about feminine wet wipes. Rinsing with water is still better.
