About
Opnjar is a plain reference for what skincare ingredients do, built for people who read labels. It stores nothing about you: no accounts, no analytics, no cookies, and no requests leave this page except for the typeface. The same data ships inside the mobile apps as a local database, updated with each app release.

Comedogenic ratings are the 0 to 5 rabbit-ear scale from the published literature, a rough guide and not a prediction for any one person. The Malassezia flag marks fatty-acid ingredients between C11 and C24 and matters only for people prone to fungal acne. Skin-type cautions come from a reviewed rule set, not from testing. Concentration, formula and your own skin decide outcomes, so treat every line here as a starting point for reading a label, not a verdict.
