The vulva is the entire external genital area of the female body. It includes everything you can see on the outside, from the soft folds of skin (labia) to the clitoris to the openings of the urethra and vagina. Many people use “vagina” when they actually mean vulva, but the vagina is the internal canal, while the vulva refers specifically to the outer structures.
Parts of the Vulva
The vulva is made up of several distinct structures, each with its own role.
The mons pubis is the rounded, fatty pad of tissue at the front, over the pubic bone. After puberty, it’s typically covered in hair. Below it, two larger skin folds called the labia majora (outer lips) run vertically on either side and encase the more delicate structures within. These outer lips are filled with erectile tissue that becomes engorged with blood during arousal.
Inside the outer lips sit the labia minora (inner lips), which are thinner, hairless folds. They extend from above the clitoris down to the perineum, the small patch of skin between the vaginal opening and the anus. The upper portion of the inner lips forms the clitoral hood, a small flap of tissue that covers and protects the clitoris.
The clitoris itself is mostly internal, but a roughly pea-sized portion called the glans sits just beneath the clitoral hood. It contains more than 10,000 nerve endings, making it the most nerve-dense structure in the human body. Its sole function is sexual pleasure.
The vestibule is the smooth 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.
Vulva vs. Vagina
These terms are used interchangeably in everyday conversation, but they describe different parts of the body. The vulva is everything on the outside. The vagina is the internal muscular canal that connects the vulvar vestibule to the cervix. The vaginal opening, visible within the vestibule, is the boundary between the two. Knowing the difference matters for describing symptoms accurately. Pain on the outer skin is a vulvar issue; discomfort or discharge from inside the canal is vaginal.
What the Vulva Does
The vulva serves three main purposes: protection, sensation, and acting as a passageway. The labia majora and minora shield the urethral and vaginal openings from bacteria, friction, and irritation. The clitoris and the surrounding nerve-rich tissue provide sexual sensation. And the vestibule houses the openings through which urine, menstrual blood, and babies exit the body.
Normal Variations in Appearance
Vulvas vary enormously from person to person. The inner lips may be longer than the outer lips, or they may be tucked entirely inside. One side is often larger than the other. Color ranges from pink to brown to dark purple, and it’s common for the labia to be a different shade than the surrounding skin. Pubic hair patterns, thickness, and coverage also differ widely. None of these variations are medical problems.
How the Vulva Changes Over Time
Hormones reshape vulvar tissue at several points in life. During puberty, estrogen triggers the growth of pubic hair and the fullness of the labia. Pregnancy increases blood flow to the area, often causing temporary swelling or color changes.
After menopause, declining estrogen levels lead to noticeable shifts. The vulvar skin can become thinner, drier, and less elastic. The labia may decrease in size, and the tissue can feel more fragile or easily irritated. These changes, sometimes grouped under the term “genitourinary syndrome of menopause,” affect up to half of postmenopausal women and are treatable.
Common Vulvar Conditions
Because the vulvar skin is thinner and more sensitive than skin elsewhere on the body, it’s prone to irritation. Vulvar dermatitis is one of the most frequent issues, with itching as the hallmark symptom. It can range from mild to severe and may include burning, stinging, thickened patches, redness, or pain during intercourse or tampon insertion. Common triggers include scented soaps, laundry detergents, and synthetic underwear fabrics.
Inflammatory skin conditions like lichen sclerosus and lichen planus can also affect the vulva. Unlike simple irritation, these conditions can cause scarring over time and may change the appearance of the vulvar structures. Persistent itching, white patches, or skin that tears easily are reasons to get evaluated.
Other conditions that show up on the vulva include yeast infections (which cause external itching along with vaginal discharge), ingrown hairs, cysts of the vestibular glands, and, rarely, vulvar cancer. Anything that persists for more than a couple of weeks, changes color, or feels like a new lump is worth having looked at.
Caring for Vulvar Skin
The vulva requires very little in the way of special care. Plain warm water is the best cleanser. The American College of Obstetricians and Gynecologists recommends against feminine hygiene sprays, scented tampons, “full body deodorants,” and douching. These products disrupt the natural balance of the area and are a leading cause of vulvar irritation.
The vaginal canal has a naturally acidic pH (around 3.8 to 4.5) that keeps harmful bacteria in check. Soaps and fragranced products can raise that pH, creating an environment where infections thrive. For the external vulvar skin, if you prefer to use a cleanser, choose one that’s fragrance-free, dye-free, and designed for sensitive skin. Pat dry rather than rubbing, and opt for cotton underwear when possible.
