Vulvar eczema typically appears as red, irritated patches of skin with poorly defined edges on the vulva. The redness may be subtle or pronounced, and the skin often looks dry, flaky, or slightly swollen. In darker skin tones, the affected areas may appear more brown or grayish rather than red. Beyond what you can see, vulvar eczema almost always itches, and that persistent itch is often what drives people to search for answers.
The Key Visual Features
Unlike a rash with sharp, clearly outlined borders, vulvar eczema tends to blend gradually into the surrounding skin. The patches of redness (or darkened skin) have soft, irregular margins. You may also notice:
- Scaling or flaking on the outer labia or surrounding skin
- Small cracks or fissures, especially in skin folds
- Scratch marks from rubbing the area
- Swelling during a flare
In the early or mild stages, vulvar eczema can look like nothing more than slightly pink, dry skin. That subtlety is part of why it often goes undiagnosed. Many women assume the irritation is from a yeast infection or normal sensitivity.
How It Changes Over Time
When vulvar eczema persists and the itch-scratch cycle takes hold, the skin starts to change in more noticeable ways. Repeated scratching and rubbing causes the skin to thicken and develop exaggerated skin lines, a process called lichenification. The affected area can look leathery, rough, and darker than the surrounding skin. These thickened, potentially discolored patches form because the top layer of skin grows thicker in response to constant friction.
This chronic stage is sometimes diagnosed as lichen simplex chronicus, which is essentially what happens when any type of eczema or dermatitis triggers a long-standing scratch cycle. The skin becomes dry, scaly, and patchy. At this point, the visual changes are more obvious and can persist even after the original eczema trigger is removed, because the scratching itself keeps the inflammation going.
What It Feels Like
The hallmark sensation is itch, which can range from mildly annoying to completely disruptive. But vulvar eczema doesn’t stop at itching. Many women also experience burning and stinging, especially after contact with urine, sweat, or products. Pain during sex is common, particularly when the skin is cracked or raw from scratching. About 60% of women with vulvar eczema in one clinical study reported provoked pain, meaning pain triggered by touch or pressure.
The itch tends to worsen at night, during periods, or after exposure to irritants. It can be intense enough to disrupt sleep and daily life.
How It Differs From Lichen Sclerosus
Lichen sclerosus is the condition most commonly confused with vulvar eczema, and distinguishing between them matters because the treatments differ. Lichen sclerosus produces white, shiny, wrinkled patches of skin that look almost like parchment paper. The skin thins rather than thickens, and it tends to develop in a figure-eight pattern around the vulva and anus. Over time, lichen sclerosus can cause the skin to scar and the anatomy to change, with the labia shrinking or the clitoral hood fusing.
Vulvar eczema, by contrast, causes thickening rather than thinning, redness or darkening rather than whitening, and does not alter the vulvar anatomy permanently. Both conditions itch significantly, but women with lichen sclerosus are more likely to report spontaneous pain (not triggered by touch), while eczema pain tends to be provoked by contact. Women with vulvar eczema are also more likely to have a history of allergies. In one study, 62.5% of women with vulvar eczema had allergies compared to 27.3% of those with lichen sclerosus.
Common Triggers and Causes
Vulvar skin is thinner and more absorbent than skin on most other parts of the body, which makes it especially vulnerable to irritants. The most common culprits include body soaps, scented lotions, fabric softeners, dryer sheets, and laundry detergents with enzymes or brighteners. Feminine products are frequent offenders: douches, vaginal deodorants, scented pads and tampons, and over-the-counter vaginal creams.
Less obvious triggers include colored or scented toilet paper, bubble bath, bath salts, nylon underwear, panty hose, pre-lubricated condoms, and spermicides. Even baby wipes and adult wipes marketed as “gentle” can contain preservatives that irritate vulvar skin. For some women, the eczema is driven by an underlying tendency toward atopic dermatitis (the same type of eczema that affects hands, elbows, and behind the knees), and the vulva is simply another site where it flares.
Treatment and Daily Skin Care
The first step in managing vulvar eczema is removing the irritant. Switch to fragrance-free laundry detergent without enzymes, skip fabric softener, and stop using any scented products on or near the vulva. Wash with water alone or a gentle, unscented cleanser. Wear cotton underwear and avoid tight clothing.
During flares, topical steroid creams are the standard treatment. Because vulvar skin absorbs medication more readily than thicker skin elsewhere on the body, lower-potency steroids are typically used, applied once or twice daily during active flares. Twice-daily application is generally recommended when the eczema is acute. Prolonged use of stronger steroids on the vulva can cause skin thinning, so treatment is usually tapered once symptoms improve. For longer-term maintenance, non-steroidal anti-inflammatory creams (calcineurin inhibitors) are specifically recommended for the genital area because they don’t cause thinning with extended use.
To prevent flares from returning, applying a maintenance treatment two to three times per week to previously affected areas can help keep the skin stable.
Moisturizers and Barrier Creams
Daily moisturizing protects the vulvar skin barrier and helps prevent flares between episodes. Unscented emollients work well for everyday use. Products like CeraVe Daily Moisturizing Lotion, Cetaphil Moisturizing Lotion, or Aveeno lotions are commonly recommended options. When the skin is more severely irritated, or if urine or pad contact is worsening things, a thicker barrier cream provides more protection. Plain petroleum jelly is effective, as are zinc oxide-based creams originally designed for diaper rash.
Applying a thin layer of moisturizer or barrier cream after bathing and before bed can make a significant difference over time. The goal is to keep the skin soft enough that it doesn’t crack and to reduce the friction and dryness that trigger the itch-scratch cycle in the first place.
