Sunburn to tan overnight: what to know

A tan is a response to ultraviolet exposure, while a sunburn reflects inflammatory skin damage. Redness may later fade into darker or uneven pigmentation, but that change does not mean the skin has recovered. Peeling and tenderness can follow, and fluid-filled blisters suggest a deeper burn. See more about [Sunburn](/conditions/sunburn/) and [Sun-Damaged Skin](/conditions/photoaging/).

Leave the sun and keep the affected skin covered with loose clothing. Cool the area with a damp compress or a cool shower, then pat dry. Apply a bland moisturiser while the skin is slightly damp; [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may be discussed if dryness is marked. Drink fluids, avoid picking peeling skin, and do not break blisters. Avoid tanning beds, intentional sun exposure, scrubs and irritating products until the skin feels normal.

Seek prompt medical advice for extensive blistering, severe swelling, worsening pain, fever, chills, vomiting, dizziness, confusion, fainting, or signs of dehydration. Urgent assessment is needed for eye pain or vision changes after exposure near the eyes. A clinician can assess unusual colour change, infection, or a burn that is not improving.

Ask whether the burn needs an examination, which moisturiser is suitable, and whether any treatment such as [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) is appropriate for your specific skin findings. Mention blistering, medicines, and how long the colour has been changing.
