The external part of female genitalia, properly called the vulva, is made up of several visible structures: the outer lips (labia majora), inner lips (labia minora), the clitoris and its hood, the urethral opening, and the vaginal opening. What many people casually refer to as the “vagina” is actually the vulva, since the vagina itself is an internal canal that isn’t visible from the outside. Every vulva looks different, and there is an enormous range of normal shapes, sizes, and colors.
External Anatomy at a Glance
Starting from the top, the mons pubis is the soft, rounded mound of fatty tissue that sits over the pubic bone. Below it, the labia majora (outer lips) are two larger folds of skin that run downward on either side, forming the outer boundary of the vulva. These outer lips may be plump or flat, smooth or textured, and they typically have hair on their outer surface after puberty.
Inside the outer lips sit the labia minora (inner lips), which are thinner, more delicate folds of skin. They surround and protect the urethral opening (where urine exits) and the vaginal opening. At the top, where the inner lips meet, they form a small hood of skin that covers the clitoris, a small, sensitive structure that responds to sexual stimulation. Behind the clitoris, the vestibule is the smooth area where both the urethral and vaginal openings are located.
Wide Range of Normal Shapes and Sizes
One of the most common concerns people have is whether their labia look “normal.” The reality is that labia vary dramatically from person to person. Studies measuring the inner lips found an average width of about 15 to 16 millimeters on each side, but the range spanned from 1 millimeter all the way to 45 millimeters. Roughly one in ten women has inner lips wider than 26.5 millimeters. All of these measurements fall within healthy variation.
The two sides don’t have to match, either. Asymmetry is common and expected. One inner lip may be noticeably longer or wider than the other. Some people have inner lips that are tucked neatly inside the outer lips, while others have inner lips that extend well beyond them. The outer lips themselves can range from full and puffy to thin and open. None of these variations indicate a health problem.
Color and Pigmentation Differences
Vulvar skin comes in a wide spectrum of colors that often differs from the skin on the rest of the body. Common tones include pink, tan, dark brown, reddish-brown, burgundy, and wine-colored. It’s completely normal for the vulva to be significantly darker or lighter than surrounding skin, and for different parts of the vulva to be different shades from each other. The inner lips, for example, are often a different color than the outer lips.
Color also shifts with blood flow. During arousal, increased circulation can give the vulva a deeper, purplish tone. This is temporary and resolves on its own.
Normal Discharge and Moisture
A healthy vulva and vagina produce moisture, and it’s normal to see discharge on underwear. This discharge changes throughout the menstrual cycle due to hormonal shifts. In a typical 28-day cycle, the pattern looks roughly like this:
- After a period (days 1 to 4): Dry or tacky, white or slightly yellow.
- Days 4 to 6: Sticky and slightly damp, white in color.
- Days 7 to 9: Creamy, yogurt-like consistency. Wet and cloudy.
- Days 10 to 14 (around ovulation): Slippery, stretchy, and clear, resembling raw egg whites. This lasts about three to four days.
- Days 15 to 28: Gradually dries up until the next period.
Healthy discharge is generally white, off-white, or clear, and has little to no odor. The egg-white consistency around ovulation serves a biological purpose: it makes it easier for sperm to travel through the reproductive tract.
How Appearance Changes Over a Lifetime
The vulva doesn’t look the same at every stage of life. Hormones reshape its appearance significantly at several key points.
At puberty, the labia become larger, thicker, and more prominent. Hair begins to grow on the mons pubis and outer lips. The skin texture changes at a cellular level. As a person continues to mature, and especially after pregnancy and childbirth, labial thickness and length may increase further.
After menopause, declining estrogen levels cause tissue throughout the body to thin, and the vulva is no exception. The labia become smoother, paler, and less defined in outline. The skin loses elasticity and becomes drier, which can sometimes cause discomfort. These changes are a normal part of aging, though treatments exist for people who experience bothersome dryness or irritation.
Signs Worth Getting Checked
Because vulvas vary so much, it helps to become familiar with your own normal appearance so you can notice changes. A few things are worth bringing to a healthcare provider’s attention: a new lump, bump, or open sore that doesn’t heal; persistent itching that won’t go away; unexplained bleeding unrelated to menstruation; pain or tenderness in the vulvar area; or noticeable changes in skin color or thickening of the skin that are new for you. These don’t automatically signal something serious, but they deserve evaluation.
