Your vulva is the entire external part of the female genitalia. It includes everything you can see on the outside: the soft mound of tissue over the pubic bone (mons pubis), the outer and inner lips (labia majora and labia minora), the clitoris, and the openings to the urethra and vagina. The vagina, by contrast, is the internal canal that connects to the cervix. Many people use “vagina” when they actually mean “vulva,” but they’re distinct structures.
Parts of the Vulva
The mons pubis is the rounded pad of fatty tissue that sits over your pubic bone. It’s typically covered with pubic hair after puberty and contains glands that release pheromones. It acts as a cushion during sexual activity.
The labia majora are the larger, outer folds of skin that form the visible borders of the vulva. They enclose and protect the more delicate structures underneath, including the inner lips, clitoris, and vaginal opening. During arousal, they fill with increased blood flow and become slightly swollen.
The labia minora are the smaller, inner folds. They start at the clitoris, where they form the clitoral hood (a small flap of skin that covers and protects the clitoral tip), then extend downward along either side of the vaginal opening. Like the outer lips, they also swell during arousal.
The clitoris sits at the top of the vulva where the inner lips meet. Most of the clitoris is internal, but the small external tip (the glans) is packed with nerve fibers. A 2023 histomorphometric study found approximately 10,280 myelinated nerve fibers innervating the clitoral glans, significantly more than the commonly cited figure of 8,000. Its primary function is sexual pleasure.
The vestibule is the area enclosed by the inner lips. It contains two openings: the urethral opening (where urine exits) and the vaginal opening. Small glands near the vaginal opening produce moisture during arousal.
Normal Variations in Appearance
Vulvas vary enormously in size, shape, color, and symmetry. A large study that developed measurement standards for the vulva found labia minora width ranged from 2 to 50 mm, and length ranged from 3 to 76 mm. In about 36% of participants, the inner lips protruded beyond the outer lips. In roughly 22%, they sat at the same level. Neither presentation is abnormal.
Color varies just as much. Around 50% of participants had inner lips that were darker than their outer lips, while 33% had noticeably different coloring between their left and right inner lips. Nearly 58% had color variation within a single inner lip, meaning one part was darker than another. About 59% had outer lips darker than the surrounding skin. Texture was roughly split between smooth and slightly ridged.
Asymmetry is also common. About 31% of participants had a noticeable size difference (5 mm or more) between their left and right inner lips. The study found no connection between labia size and dissatisfaction with genital appearance, and no link between size and sexual function scores. In short, there is no single “normal” look.
How Your Vulva Changes Over Time
Vulvar tissue responds directly to hormone levels. During puberty, rising estrogen causes the labia to develop, pubic hair to grow, and the tissue to thicken and mature. These changes happen in a predictable sequence alongside broader puberty milestones.
After menopause, declining estrogen leads to tissue thinning (atrophy). The skin may become drier, less elastic, and more easily irritated. The outer lips tend to widen with age, while the inner lips gradually decrease in length and thickness. These are normal, expected shifts.
Vulvar Skin and Hygiene
Vulvar skin is more sensitive than skin elsewhere on your body. The internal vagina maintains an acidic pH of around 3.8 to 5.0 during reproductive years, thanks to beneficial bacteria that produce lactic acid. This acidity protects against infection. Products like douches, feminine sprays, and scented wipes can disrupt that balance.
The American College of Obstetricians and Gynecologists recommends keeping vulvar hygiene simple: wipe front to back, use unscented and uncolored toilet paper, and skip sprays, deodorants, douches, baby wipes, and talcum powders. Warm water is sufficient for cleaning the vulva. The vagina cleans itself internally and doesn’t need any products inside it.
Signs Worth Paying Attention To
Because you see your vulva regularly, you’re in a good position to notice changes. Symptoms that persist for two weeks or longer and aren’t typical for you deserve attention. These include itching, burning, or bleeding that won’t resolve, skin that looks noticeably redder or whiter than your baseline, sores or lumps that don’t heal, anything resembling a rash or warts, and pelvic pain during urination or sex. Many of these symptoms have straightforward causes like infections or skin conditions, but persistent changes can occasionally signal something more serious, including vulvar cancer.
