Rash or Stinging From Sunscreen: Causes and What to Switch To

Sunscreen is essential, but for some skin it brings a rash or sting. Here's what tends to cause it and how to find an SPF that suits you.

What could be going on

A few different things cause sunscreen reactions:

How to narrow it down

When to see a doctor

Do not abandon sun protection. If you keep reacting, or get a rash specifically after sun, see a GP or dermatologist to find a tolerable option and rule out light sensitivity.

Reading a label by eye, or using a free ingredient-checker, will tell you what is in a product. What it will not do is check it against the specific ingredients you react to.

To close that gap, a personal-list app like ClearaScan lets you save the ingredients you react to once and scan any product to flag only your triggers. It also keeps a Reaction Journal for flare-ups, a shared Care Circle so family or carers can scan for you, and a Trusted Products list for items you have cleared, and it is currently in early access. (Disclosure: our editor co-founded ClearaScan, and we are not paid to mention the others.)
