A skincare ingredient checker that knows your routine
Most ingredient checkers look at one product at a time. Acnera scans a product, gives you a plain-English verdict on whether it suits your skin, and checks it against everything else you already use, so you catch clashes like doubled-up acids before they reach your face.

How to use it
Each product comes with usage tips, so a good product does not fail because it was used the wrong way.

Frequently asked questions
How does a skincare ingredient checker work?
You scan or look up a product, and the checker reads its ingredient list. Acnera gives you a verdict on how well the product suits your skin and flags conflicts with the other products in your routine.
Can it tell me if a product will break me out?
No checker can promise that, because skin reacts differently and pore-clogging ratings have real limits. Acnera tells you how well a product fits your skin and flags risky combinations, and tracking your skin after you start it gives you the final answer.
Which skincare ingredients should not be mixed?
The main ones are tretinoin with benzoyl peroxide, and retinoids with exfoliating acids in the same routine. Many other "never mix" rules are overstated. Acnera checks your routine for these combinations automatically.
Is the ingredient scanner free?
Acnera is free to download on the App Store. Acnera Pro unlocks the full experience as a subscription, and the annual plan includes a free trial.
