Not medical advice

Patch Test explains skincare ingredients, routines, sunscreen and the rules for cosmetics in the US, Korea and Malaysia. It is written for general information and is no substitute for a doctor, a dermatologist or a pharmacist. Rashes, persistent acne, pigmentation changes and reactions to a product deserve a professional opinion. Before using a new active ingredient, test it on a small patch of skin first, and follow the directions on the product.

Guides that discuss a particular product rely on the ingredient list and claims the brand itself has published, on the date given in the guide. Formulas change; the packaging in your hand is the reference.

The former shop on this domain

This address once belonged to a beauty retailer. Patch Test is not its successor: it holds none of that shop's customer records and cannot answer questions about past orders, payments or deliveries. The full background is under About this domain.

Privacy

There is no shop, account or newsletter here, so no personal details are collected. The site sets no cookies and runs no analytics or advertising; fonts load from this domain. Cloudflare, which hosts the site, keeps technical logs of requests (including IP addresses) for security.
