“Pussy lips” is a colloquial term for the labia, the two pairs of skin folds that surround the vaginal opening and urethra. Every vulva has two sets: the labia majora (outer lips) and the labia minora (inner lips). Together, they protect sensitive internal structures and play a role in sexual sensation.
Outer Lips vs. Inner Lips
The labia majora, or outer lips, are the larger, fleshier folds that form the visible outer border of the vulva. They contain fatty tissue and, after puberty, grow pubic hair on their outer surface. These folds cover and protect everything underneath: the inner lips, the clitoris, the urethral opening, and the vaginal opening.
The labia minora, or inner lips, are thinner folds of skin that sit just inside the outer lips. They begin at the clitoris, where the front folds form the clitoral hood, then extend downward along both sides of the vaginal opening. The inner lips have no hair and contain more nerve endings than the outer lips, making them more sensitive to touch.
What the Labia Actually Do
The labia serve as a physical barrier that shields the urethra and vaginal opening from friction, bacteria, and debris. The outer lips act like a cushion during activities like walking, exercise, and sex. The inner lips help direct urine flow and keep the vaginal entrance partially covered, which reduces exposure to outside irritants.
During sexual arousal, increased blood flow causes both sets of lips to swell and become more sensitive. The tissue may deepen in color as it engorges. This swelling is part of the body’s normal arousal response and contributes to heightened sensation during sexual activity.
Normal Size, Shape, and Color Vary Widely
There is no single “normal” appearance for the labia. Size, shape, color, and symmetry vary significantly from person to person, influenced by genetics, age, hormonal status, and body composition. In a study of 220 women, labia minora length ranged from 30 to 80 millimeters, while labia majora length ranged from 60 to 110 millimeters. The width of the inner lips varied just as dramatically, from as narrow as a few millimeters to as wide as 60 millimeters at their broadest point.
It is completely common for one lip to be longer or thicker than the other. The inner lips may extend past the outer lips or be tucked entirely inside. Color ranges from pink to brown to purple, and the inner lips are often a different shade than the surrounding skin. None of these variations indicate a health problem. Interestingly, the study found no significant differences in labial measurements across age groups, suggesting the labia remain relatively stable in size throughout adulthood.
Vaginal delivery can slightly increase labial dimensions. Women who had given birth vaginally had, on average, longer labia majora (about 91 mm vs. 87 mm) and longer labia minora (about 57 mm vs. 51 mm) compared to those who had not.
How the Labia Change Over a Lifetime
The labia go through noticeable changes at several life stages. At birth, residual hormones from the mother can make a newborn’s labia appear temporarily swollen. During puberty, rising hormone levels cause the outer lips to fill out with fatty tissue, the inner lips to grow and take on a more defined shape, and pubic hair to develop. These changes happen gradually alongside other signs of sexual maturation.
During the reproductive years, the labial tissue stays relatively thick and well-moisturized under the influence of cycling hormones. Pregnancy can cause temporary swelling and darkening due to increased blood flow. After menopause, declining hormone levels lead to tissue thinning, reduced elasticity, and less natural moisture. The outer lips may lose some of their fullness as fatty tissue decreases.
Common Bumps and Lumps
Finding a bump on your labia can be alarming, but most labial lumps are harmless. The most common is an epidermal inclusion cyst, a small, firm, round bump that appears on the outer lips. These are the most frequently seen skin cyst anywhere on the body, and on the vulva they typically show up as yellow-white nodules ranging from a few millimeters to a few centimeters. They don’t require treatment unless they become painful or bothersome.
Bartholin gland cysts develop near the vaginal opening, typically felt as a small, soft swelling at roughly the 4 or 8 o’clock position. These glands normally produce small amounts of lubricating fluid, but if a duct gets blocked, fluid can build up into a painless cyst. Many resolve on their own.
Vestibular papillomatosis is a condition that looks like tiny, finger-like projections on the inner lips and vestibule. It’s often mistaken for genital warts, but it’s actually a normal anatomical variant that doesn’t need treatment. Unlike warts, these projections appear soft, symmetrically distributed, and confined to the inner lips.
Small, painless skin-colored bumps on the outer lips can also be seborrheic keratoses (waxy, “stuck-on” looking growths that become more common with age) or sweat gland tumors called syringomas, which appear as tiny firm papules in a symmetrical pattern. Both are benign.
Caring for Labial Skin
The skin of the vulva is more sensitive and permeable than skin elsewhere on your body, which makes it more reactive to irritants. Current medical guidance recommends avoiding conventional soaps, shower gels, scented products, and antiseptic washes on the vulva. Fragrance-free, pH-balanced liquid cleansers are a better choice, and you should rinse thoroughly. Wash with your hands rather than a washcloth, and clean from front to back.
Once or twice a day is sufficient. During menstruation, washing morning and evening is reasonable, with an additional wash after changing a tampon or menstrual cup. Vaginal douching is consistently discouraged because it disrupts the natural bacterial balance. Deodorants or perfumed products applied to the vulva before sex are also not recommended, as they increase the risk of irritation.
After menopause, when the labial tissue becomes thinner and drier, gentle care matters even more. Mild, fragrance-free, hypoallergenic products help preserve skin integrity and moisture without triggering irritation.
