What is a skincare ingredient checker?

SkinChecker is a free skincare ingredient checker for the UK. Paste in a product, search a brand, or browse our ingredient glossary to see exactly what's in your skincare — every item on the INCI label translated into plain English, with what it does and who it tends to suit. Instead of fear-based "good" and "bad" lists, we give balanced, nuanced notes so you can decide what's right for your own skin.

Wondering what's actually in your moisturiser, serum or cleanser? Start with a product search, explore ingredients by skin concern — dryness, acne, redness, sensitivity, dark spots and barrier support — or read how we categorise ingredients in our methodology.

How we analyse ingredients: We categorise ingredients in simple, user-friendly ways based on their common function and known sensitivities. Skin reactions vary by individual. Our notes are educational, not medical advice. If you have allergies or medical concerns, always verify ingredients directly with the manufacturer or your dermatologist.
