Natural Remedies for Rashes

A rash can reflect irritation, allergy, infection, dry skin or inflammation around hair follicles. Small rough bumps on the upper arms or thighs may fit [Keratosis Pilaris](/conditions/keratosis-pilaris/), while pus-filled bumps can occur with [Folliculitis](/conditions/folliculitis/). Shaving-related bumps may be [Razor Bumps](/conditions/pseudofolliculitis-barbae/) or [Ingrown Hairs](/symptoms/ingrown-hairs/), and each problem may need a different plan.

Rinse gently with lukewarm water, pat dry and apply a plain, fragrance-free moisturiser. Wear loose clothing, avoid scratching and pause any new cosmetic, detergent or shaving product that touches the area. Do not use lemon, vinegar, toothpaste, bleach, undiluted essential oils or abrasive scrubs. Do not pop pustules or dig for trapped hairs. If shaving repeatedly triggers bumps, a clinician can explain whether [Laser Hair Removal](/treatments/laser-and-energy/laser-hair-removal/) is suitable for your skin and hair.

Get urgent help for a rash with breathing difficulty, swelling of the lips or tongue, faintness, blistering, skin peeling, severe pain or fever. Arrange assessment if it spreads quickly, becomes warm or pus-filled, follows a new medicine, or does not improve after removing an obvious irritant. A diagnosis is especially useful when the rash keeps returning.

Could this be infection, eczema, allergy or a shaving-related condition? Which cleanser and moisturiser should I use? Should I stop shaving temporarily? What signs suggest the area needs treatment rather than home care?
