What should you know about a rash in the groin area in females?

Sweat and rubbing can inflame the groin crease or outer vulval skin. Intertrigo may affect moist folds; ringworm can produce a scaly border. Contact dermatitis can follow sanitary products, fragranced washes, wipes, laundry products, lubricants, or hair-removal products. Atopic dermatitis and psoriasis can also affect genital-area skin, sometimes with little scale. A drug rash may follow a new medicine. Itching, burning, soreness, discharge, odour, sores, or pain when passing urine help a clinician decide whether the problem is skin-related or needs gynaecological assessment.

Do not put household remedies, antiseptics, or scented products on the vulva. The vagina and the surrounding external skin are different areas, and treatment for one is not necessarily suitable for the other.

Clean the external area gently with lukewarm water or a bland, fragrance-free cleanser, then pat dry. Wear breathable underwear, change after sweating, and avoid tight clothing while the skin is sore. Pause new products and avoid douching. Keep creams away from the vaginal opening unless a clinician or product instructions specifically direct their use. A pharmacist or clinician can recommend treatment after checking whether the rash is on a fold, vulval skin, or both.

Book an assessment for a persistent, recurrent, spreading, or unexplained rash. Seek prompt help for severe swelling or pain, blisters, ulcers, pus, fever, rapidly worsening redness, pelvic pain, unusual discharge, or painful urination. Pregnancy, diabetes, or reduced immunity lowers the threshold for seeking advice.

Which exact skin area is affected? Could this be contact dermatitis, intertrigo, ringworm, or psoriasis? Do I need testing, and which products are safe around the vulva?
