Natural remedies for sun allergy

Sun allergy, often called polymorphic light eruption, can cause itchy red bumps, patches, or small blisters on areas exposed to sunlight. It may appear after time outdoors and can recur with later exposure. The pattern can resemble other rashes, so a clinician may need to distinguish it from contact dermatitis, heat rash, or a medication-related reaction.

Move into shade or indoors when symptoms begin. Cover exposed skin with tightly woven clothing, a wide-brimmed hat, and sunscreen suited to sensitive skin. Apply a cool, damp cloth for short periods and use a plain, fragrance-free moisturiser after washing. Avoid scratching, fragranced oils, lemon juice, and essential oils; these can irritate already inflamed skin or increase sensitivity. If episodes keep returning, a dermatologist can discuss options such as topical corticosteroids or narrowband UVB phototherapy.

Arrange medical advice if the rash is widespread, painful, blistered, infected-looking, or repeatedly returns despite careful sun protection. Seek urgent help for swelling of the lips or tongue, trouble breathing, faintness, or a rapidly spreading reaction. A new rash after starting a medicine also deserves prompt review.

Ask whether the pattern fits polymorphic light eruption, whether any medicine or skincare product could be contributing, and which sunscreen and treatment are suitable for your skin.
