Universal Score vs Personal Avoidance List: Which Approach Wins?
Most ingredient apps give every product a universal score. A personal avoidance list asks a different question. Here's why the difference matters for sensitive skin.
Two different questions
Most ingredient apps (Yuka, Think Dirty, EWG and others) answer “is this product generally good or bad?” with a universal score. A personal avoidance list answers a different question: “does this product contain something I react to?”
Why the difference matters
For general clean-shopping, a universal score is useful. But sensitive and allergy-prone skin is personal: you might tolerate most of a “low-scoring” product and react badly to one ingredient in a “high-scoring” one. A score cannot know your triggers; only a list of your ingredients can.
The trade-off
- Score-based scanners: quick, no setup, good general signal, but generic.
- Personal list: a minute of setup to add your triggers, then every scan is tailored to you.
Where ClearaScan sits
Reading a label by eye, or using a free ingredient-checker, will tell you what is in a product. What it will not do is check it against the specific ingredients you react to.
To close that gap, a personal-list app like ClearaScan lets you save the ingredients you react to once and scan any product to flag only your triggers. It also keeps a Reaction Journal for flare-ups, a shared Care Circle so family or carers can scan for you, and a Trusted Products list for items you have cleared, and it is currently in early access. (Disclosure: our editor co-founded ClearaScan, and we are not paid to mention the others.)
The verdict
A universal score is a fine starting point; a personal avoidance list is what actually answers the question when your skin reacts to specific things.
