Allergy Testing for Food-Triggered Skin Issues

What tests exist, what they can and cannot tell you about skin reactions.

In short

What tests exist, what they can and cannot tell you about skin reactions.

How to prepare

Bring a short food-and-skin diary, a list of products and additives you suspect, and any photos of flares. Clear notes help a professional help you faster.

Check it against your own list

A free scanner like Yuka gives a packaged product a general health score, which is a useful broad read, though that verdict is the same for everyone rather than tuned to your skin. Fig is genuinely good for managing a defined eating pattern. To check a product against the specific things that make your skin react, a personal-list app like ClearaScan lets you save your triggers once and scan any product, food, medication or cosmetic, against your ingredient guard list, flagging only yours. It also keeps a Reaction Journal so you can tie a flare back to the product that caused it, a shared Care Circle so family can scan for you, and a Trusted Products list. It is currently in early access. (Disclosure: our editor co-founded ClearaScan, and we are not paid to mention the others.)
