Bumps on the vulva (the outer genital area often called the “vagina”) are extremely common and usually caused by inflamed hair follicles. The vulva is covered in hair follicles and oil glands, and it spends most of the day in a warm, moist, friction-heavy environment. That combination makes it one of the most pimple-prone areas on the body. Most of the time, these bumps are harmless and resolve on their own, but some types deserve a closer look.
Folliculitis: The Most Common Cause
The vast majority of pimple-like bumps on the vulva are folliculitis, which is inflammation of a hair follicle. It looks almost identical to a facial pimple: a small, round bump that may have a white or yellowish head. Folliculitis is typically caused by bacteria (most often staph) entering a damaged hair follicle. Shaving, waxing, tight underwear, and sweaty workout clothes all create the perfect conditions for it.
You might notice clusters of small bumps, itching or burning, tenderness, or pus-filled spots that eventually crust over. These bumps usually don’t cause much pain unless they’re irritated by friction. A single bump that shows up a day or two after shaving is almost always an ingrown hair or minor folliculitis.
Hormonal Breakouts Around Your Period
If you notice vulvar bumps appearing on a monthly schedule, hormones are likely involved. Your oil glands are controlled largely by androgens like testosterone, and androgen activity fluctuates throughout your menstrual cycle. In the week leading up to and during your period, sebum production tends to increase. That extra oil can clog pores and hair follicles anywhere on the body, including the vulva. Sebum production is typically lowest around ovulation, when estrogen peaks and helps suppress oil output.
Fordyce Spots: Bumps That Were Always There
Sometimes the “pimples” you notice aren’t pimples at all. Fordyce spots are enlarged oil glands that appear as tiny, pale or skin-colored raised dots. They’re painless, they don’t have a head, and they don’t come and go. Between 70% and 80% of adults have Fordyce spots somewhere on their body, and the genital area is one of the most common locations. They’re completely normal anatomy and don’t need treatment.
Bartholin’s Cysts
The Bartholin’s glands sit on each side of the vaginal opening and produce fluid for lubrication. When one of these glands gets blocked, fluid backs up and forms a cyst. A Bartholin’s cyst feels like a firm, round lump near the vaginal opening, deeper than a surface pimple. Small ones are painless and you may not notice them. Larger ones can become tender or infected, forming an abscess that’s swollen, red, and very painful. Because of their specific location (lower left or lower right of the vaginal opening), they’re fairly easy to distinguish from a regular pimple.
When It Might Not Be a Pimple
A few other conditions can masquerade as pimples, and it helps to know what sets them apart.
Genital Herpes
Herpes sores start as tiny, clear or reddish fluid-filled blisters that form in clusters with a shiny, wet appearance. When they burst, they become shallow, painful ulcers with a red base. The key differences from a pimple: herpes blisters appear in grouped, somewhat symmetrical patterns, they contain clear (not white or yellow) fluid, and they cause significant ongoing pain. A pimple is usually a single, round bump with thick pus that causes only mild soreness.
Molluscum Contagiosum
Molluscum bumps are small, firm, and raised with a characteristic dimple or dip in the center. They’re caused by a virus that spreads through skin-to-skin contact, including sex, or by touching contaminated towels or clothing. You can also spread them to other parts of your own body by scratching. They’re painless but tend to multiply over time rather than resolving quickly like a pimple.
Genital Warts
Warts are caused by certain strains of HPV and appear as soft, flesh-colored growths that can be flat or raised with a rough, cauliflower-like texture. They don’t look much like pimples up close, but a single small wart can be confusing at first glance.
A physical exam alone isn’t always enough to accurately diagnose a genital bump. If a bump is ulcerated, keeps coming back, appears in clusters, or doesn’t heal within a couple of weeks, getting tested is worthwhile. The CDC recommends that any genital ulcer be evaluated for herpes, syphilis, and HIV, because visual diagnosis is frequently inaccurate even for clinicians.
How to Treat a Vulvar Pimple at Home
The skin on and around the vulva is significantly more sensitive than facial skin. Products you’d use on your face, like benzoyl peroxide or salicylic acid, can cause irritation, burning, or disruption of the vaginal environment. Don’t apply over-the-counter acne treatments to this area without guidance from a provider.
For a standard pimple or ingrown hair, the best approach is simple. Apply a warm compress for 10 to 15 minutes a few times a day to encourage the bump to drain on its own. Wear breathable cotton underwear and avoid tight clothing until it heals. Don’t squeeze, pop, or pick at it, as this pushes bacteria deeper and can turn a minor bump into a larger infection. If you can see an ingrown hair curled under the surface, you can gently lift the tip with a clean, sterilized needle, but avoid digging into the skin.
How to Prevent Vulvar Pimples
Shaving is the single biggest trigger. Every time a razor passes over the skin, it can nick hair follicles and create entry points for bacteria. If you shave and get frequent bumps, consider these changes:
- Let hair grow slightly. Keeping hair trimmed to about half a centimeter instead of shaving to the skin eliminates most ingrown hairs.
- Use a clean, sharp razor. Dull blades require more pressure and cause more follicle damage.
- Shave in the direction of hair growth. Going against the grain gives a closer shave but dramatically increases the chance of ingrown hairs.
- Consider alternatives. Chemical depilatories remove hair without cutting it below the skin surface, which avoids the ingrown hair cycle entirely. They can irritate sensitive skin, though, so patch-test first. Laser hair removal permanently reduces hair and is the most effective long-term solution for chronic folliculitis.
Beyond hair removal, a few habits make a difference. Change out of sweaty clothes and damp swimsuits promptly. Avoid scented soaps, douches, and body washes in the vulvar area, as these disrupt the skin’s natural barrier. If you’re prone to friction from exercise or thigh contact, moisture-wicking underwear or anti-chafe products can help.
Signs a Bump Needs Medical Attention
Most vulvar bumps are minor irritations, but certain features suggest something more serious. A bump that keeps growing, especially a dark or black spot that changes size, should be evaluated to rule out skin cancer. A bump that bleeds easily and doesn’t heal could also be a concern. Fever, swollen lymph nodes in the groin, or foul-smelling discharge alongside a bump suggest the infection may have spread beyond a single follicle. And any bump that recurs in the same spot repeatedly, or appears alongside a new sexual partner, is worth getting tested rather than assuming it’s just another pimple.
