Yuka vs ClearaScan: Score-Based vs Your Own Avoidance List

Yuka scores products with a single rating; ClearaScan checks against your personal triggers. A fair, UK-focused look at how they differ, where each is strong, and who each suits.

The core difference

Yuka and ClearaScan are often set against each other, but they answer different questions. Yuka scans a barcode and gives the product a single score out of 100, based on its own assessment of the ingredients, and everyone sees the same verdict. ClearaScan does not score anything; it checks a product against the specific ingredients you have chosen to avoid. That is the whole distinction: a universal score versus a personal list. Both are useful tools, and for sensitive skin the right choice depends on whether you want a fast general read or a check against your own triggers.

How each one works

Yuka is hugely popular and works from its own rulebook. It reads a barcode, weighs the ingredients against its criteria, and returns one traffic-light-style number covering both food and cosmetics. The appeal is instant simplicity, and over time it gently steers you towards products it rates well. ClearaScan works the other way round. It ignores the general verdict and checks each product against your own avoid list, so it flags your triggers and stays quiet about everyone else’s. You build that list once, then scan any product, food, medication or cosmetic, and it flags only yours. It is currently in early access. The core difference is a general score versus your personal guard list.

A fair point-by-point comparison

Coverage. Yuka has a vast, mature database across food and cosmetics, so a random product is very likely to be recognised. ClearaScan spans cosmetics, food and medication, but as a newer, early-access product its database is still growing.

How each judges a product. Yuka applies its own criteria to produce one score. ClearaScan makes no general judgement; it only checks against your list. If Yuka’s criteria feel too broad, or you disagree with how it weighs certain ingredients, a personal list avoids that question entirely.

Personalisation. This is the heart of it. A Yuka score is the same for everyone, which is exactly why it can rate a product well while it still contains the one ingredient your skin reacts to. A poor score may also flag things that are completely fine for you. ClearaScan starts from your triggers, so it answers “is this right for me?” rather than “is this generally good?”.

Cosmetic versus food. Both span more than one category, which counts in each tool’s favour. Yuka covers food and cosmetics; ClearaScan checks food, medicines and skincare against one list. Either is better than a single-category tool if your triggers cross over.

Cost. Yuka has a free version and a paid tier; ClearaScan is in early access. Terms change, so check the current position in each app.

Where each falls short. Yuka’s one-size score cannot reflect your personal triggers, which is its main limit for sensitive skin. ClearaScan depends on you building an accurate list and, being newer, has less coverage than an established scorer.

Who each one suits

Yuka suits someone who wants a quick, general “is this well-rated?” verdict across everyday shopping, without any setup. It is excellent for browsing and for a broad steer. ClearaScan suits someone who already knows their specific triggers and wants them caught fast, especially in a shop, and whose triggers may span food, medicines and skincare. 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.

An honest recommendation

Use Yuka for a fast general score, and ClearaScan when what matters is whether a product contains the ingredients you personally react to. The honest trade-offs run both ways. Yuka needs no setup and has a huge database, but its single score cannot know your triggers. ClearaScan is tailored to you and spans categories, but you have to build the list yourself and it is still in early access with less coverage. For many people with sensitive skin the answer is not either-or: keep Yuka for browsing and use a personal list for the safety check. If you do not yet know what flares your skin, neither app replaces advice from a GP or dermatologist, ideally with patch testing.
