Ingredient guide

Skincare ingredients, explained

Plain-language notes on the 37 ingredients Skinvio flags when it reads a product label — what each one is, why it's flagged, and how often it actually turns up across 4,195 catalogued products.

High caution

Restricted, prescription-strength, or strongly sensitising. Worth knowing by name.

Elevated caution

Common causes of reactions, particularly in products you leave on.

Moderate caution

Fine for most people, worth watching if your skin is reactive.

Low caution

Rarely a problem, included for completeness.

Generally supportive

Ingredients that tend to be a good sign on a label.

This is cosmetic guidance, not medical advice

Skinvio does not diagnose, treat, or cure any skin condition. These notes describe general formulation patterns, not how your skin will respond. Always patch test, and speak to a licensed clinician about reactions, persistent irritation, or any changing spot or growth.
