Itchy Skin Guide: Causes, Fast Relief and Treatment by Cause
Itchy skin (pruritus) is most often caused by dry skin, eczema, an allergic reaction, a fungal infection or irritation from something that touched the skin. The fastest relief comes from cooling the skin and treating the cause: moisturiser for dryness, an antifungal for fungal itch, antihistamines for hives and an anti-inflammatory cream for rashes. This guide links every article we have written on itch, organised by cause.

Quick facts
- Dry skin is the most common cause of itch, especially in winter and in older adults.
- A rash that is ring-shaped, in the groin or between the toes is often fungal and needs an antifungal, not a steroid alone.
- Cooling ingredients such as menthol and numbing ones such as pramoxine relieve itch quickly while the cause is treated.
- Itch that is worse at night is common with eczema, dry skin and scabies.
- Itch all over without a rash, lasting more than 2 weeks, should be checked by a doctor because it can have internal causes.

Frequently asked questions
How do I stop itching fast?
Hold a cool, damp cloth on the area for 5 to 10 minutes, pat on a fragrance-free moisturiser and apply a cooling (menthol) or numbing (pramoxine) anti-itch cream. Then treat the cause. See how to stop itching fast.
What is the best cream for itchy skin?
It depends on the cause: a moisturiser for dry skin, hydrocortisone for a short-term inflamed rash, an antifungal for fungal itch and a cooling or numbing cream for quick relief. Our buyer's guide compares them by ingredient.
Why is my skin itchy but there is no rash?
Dry skin is the usual reason. Itch without a rash that lasts more than 2 weeks, or comes with weight loss, night sweats or tiredness, should be checked by a doctor.
When is itchy skin serious?
See a doctor urgently if itch comes with swelling of the lips or face or trouble breathing, and soon if it spreads, keeps you awake, or the skin weeps, crusts or hurts.
