Vulvovaginitis typically looks like redness and swelling of the vulva and vaginal opening, often accompanied by some type of discharge. But the specific appearance varies depending on what’s causing it. A yeast infection, bacterial imbalance, sexually transmitted infection, hormonal changes, and skin irritation each produce distinct visual patterns that can help identify what’s going on.
The General Appearance
Across all types of vulvovaginitis, certain visual signs are consistent. The skin of the vulva and surrounding area appears red, puffy, and inflamed. The tissue may look raw or feel tender to the touch. In many cases there’s visible discharge on the underwear or around the vaginal opening, though the color, texture, and smell of that discharge differ significantly by cause.
When inflammation has been going on for a while, you may also notice small cracks or fissures in the skin, areas that look scraped from scratching, or patches where the skin texture has changed. These secondary changes happen because irritated skin is fragile and breaks down more easily.
Yeast Infection Discharge
A vaginal yeast infection produces what’s often described as a thick, white, cottage cheese-like discharge. It tends to clump rather than flow, and it usually doesn’t have a strong odor. The surrounding vulvar skin is typically bright red, itchy, and irritated, sometimes with visible swelling that extends to the outer labia. The vaginal pH stays in the normal range (around 4.0), which is one reason yeast infections feel different from bacterial causes even though the redness can look similar.
Bacterial Vaginosis
Bacterial vaginosis (BV) looks quite different from a yeast infection. The discharge is thin and watery rather than thick, and it can appear gray, white, or greenish. The most distinctive feature isn’t visual at all: it’s a strong, fishy odor that tends to get worse after sex. The vulvar skin may be mildly irritated, but BV generally causes less dramatic redness and swelling than yeast or other infections. Vaginal pH rises above 4.5 when BV is present, reflecting the shift away from the healthy acidic environment that normally keeps bacteria in check.
Trichomoniasis
Trichomoniasis, a sexually transmitted infection caused by a parasite, has its own visual signature. The discharge is thin and frothy, sometimes with a yellow-green tint and an unpleasant odor. The genital tissue often looks noticeably red and swollen. One distinctive clinical finding is what’s called a “strawberry cervix,” a pattern of tiny red dots on the cervix caused by small areas of bleeding. This shows up in about 40% of people with the infection, though it’s only visible during a pelvic exam. Vaginal pH typically rises above 5.4, sometimes reaching 6.5 or higher.
Irritant and Allergic Reactions
Not all vulvovaginitis is caused by an infection. Contact with irritants like scented soaps, bubble bath, laundry detergent, dryer sheets, or wet wipes can trigger inflammation that looks very similar to an infection. The skin develops raised red bumps that can merge into larger patches of redness across the vulva, perineum, and perianal area. Itching is often intense.
These reactions are frequently misdiagnosed as infections, leading to unnecessary rounds of antifungal or antibiotic treatment that don’t help. One clue that irritation rather than infection is the cause: the redness tends to follow the pattern of skin that came into contact with the irritant, and there’s usually no significant change in discharge.
Atrophic Vaginitis After Menopause
In people who have gone through menopause, vulvovaginitis can look strikingly different. Instead of the angry redness of an infection, the tissue appears pale, shiny, and dry. The vaginal walls thin out and lose their normal ridged texture, becoming smooth and fragile. Tiny red dots called petechiae, which are spots of minor bleeding under the surface, may be visible on the vaginal walls. The vulvar skin can take on a whitish, almost waxy appearance. This happens because declining estrogen levels cause the vaginal lining to lose moisture and thickness over time.
What It Looks Like in Children
Vulvovaginitis is actually quite common in young girls before puberty. In children, it typically appears as redness and soreness around the vulva, sometimes with a small amount of discharge. The vast majority of cases, around 70% to 80%, have nonspecific causes tied to hygiene habits rather than infection. Tight clothing, bubble baths, not wiping front to back, and sitting in wet swimsuits are common triggers.
Two skin conditions can mimic or overlap with vulvovaginitis in children and have distinctive appearances. Psoriasis shows up as red, non-scaly, itchy patches that may be limited to the vulva. Lichen sclerosus, which accounts for about 15% of chronic vulvovaginitis in children, creates a paper-white rash in a figure-of-eight pattern around the vulva and anus. That pattern is distinctive enough to help identify the condition.
Comparing the Visual Differences
If you’re trying to figure out what type of vulvovaginitis you might be dealing with, the discharge is the most useful visual clue:
- Thick, white, clumpy, no strong smell: likely a yeast infection
- Thin, grayish, fishy odor: likely bacterial vaginosis
- Thin, frothy, yellow-green, bad smell: likely trichomoniasis
- No unusual discharge, but red bumpy skin: likely irritant or allergic reaction
- No discharge, pale and dry tissue: likely atrophic changes from low estrogen
That said, these categories overlap in practice, and more than one cause can be present at the same time. The degree of redness and swelling alone isn’t enough to tell causes apart, since nearly all types produce some level of visible inflammation. What distinguishes them is the combination of how the discharge looks, how it smells, and what the surrounding skin is doing.
