In the skin

Immune-related inflammation alters the structure of vulvar skin. The exact cause is not fully established, but persistent inflammation can lead to scarring and tissue change.

Immune-related inflammation affects genital skin and accelerates cell turnover. Warm, moist folds often show less visible scale than psoriasis on drier body areas.

Daily care

Habits that help

Wash the vulva gently and avoid soap or fragrance
Pat dry; use a tolerated non-soap cleanser only if needed.
Apply the prescribed emollient or barrier ointment
This reduces dryness and protects delicate skin from urine and friction.
Wear comfortable clothing and adjust painful activities
Reduce rubbing from tight seams, cycling or sex during a flare.
Follow the prescribed steroid and follow-up plan even when itch improves
Lichen sclerosus needs ongoing monitoring; moisturizer does not replace treatment.
Report a persistent sore, new lump or non-healing area promptly
New changes need examination rather than repeated self-treatment.

Avoid

Avoid: Scratching and unprescribed genital remedies
Irritation can cause tearing and worsen symptoms.

Habits that help

Moisturize regularly with a plain fragrance-free product
Apply after washing and when skin feels dry or tight.
Keep washing gentle and water lukewarm
Use a non-soap cleanser and pat dry rather than rubbing.
Protect sore skin from friction and minor injury
Comfortable clothing and gentle handling reduce avoidable irritation.
Keep a manageable record of flares and symptoms
Note new medicines, infections or joint symptoms to discuss at review.
Reduce genital friction and use only the agreed treatment plan
Wash gently, wear comfortable underwear and avoid fragranced washes; strong steroids need clinician supervision here.

Avoid

Avoid: Picking scale or scratching plaques
Injury can worsen psoriasis and create breaks in the skin.
Avoid: Unsupervised tanning or harsh home exfoliation
Sunburn and irritation can trigger worsening; prescribed phototherapy is different from tanning.

Treatment differences

Evidence labels come from each condition’s own treatment list.

Treatment

● Vulvar Lichen Sclerosus

● Genital Psoriasis

Prescription topicals

Clobetasol ointment

Listed

A supervised potent steroid regimen is standard for vulvar lichen sclerosus; ongoing review is important.

Site-specific anti-inflammatory treatment

Listed

A brief mild steroid or a steroid-sparing agent may be selected for face, folds or genital skin; avoid potent body steroids without guidance.

Outlook

Long term

Lichen sclerosus often needs long-term treatment and follow-up, even when symptoms improve. Established scarring may not reverse; a new persistent sore or thickened area should be examined.

Genital psoriasis can clear with suitable treatment but may recur. It does not usually scar; ongoing symptoms need review because infections and other genital conditions can look similar.
