Sus vs Yuka for skincare: one score for everyone, or a grade for your skin?

What Yuka does well

Yuka scans food and cosmetics and returns a single 0–100 score with a color rating. It is fast, independent, and its food scoring changed how millions of people read supermarket labels. If you want one number that says "how clean is this product by general criteria," Yuka answers that question well — for everyone at once.

Where a universal score falls short for skin

• Skin is personal. Fragrance is irrelevant to some skin and a genuine trigger for sensitized or barrier-damaged skin. One score cannot say both.
• Actives are contextual. A retinoid product can be exactly right for one routine and redundant — or irritating — layered into another. A universal score does not know what you already use.
• Marketing is not an ingredient. A label can be "clean" by any scoring rubric while its front-of-pack claims oversell what the formula can do. Hype lives outside the INCI list.

What Sus does differently

• Skincare only. Sus reads cosmetic labels — barcode, label photo, or product search — and nothing else. The entire product is built around the INCI list.
• Graded for your Skin ID. You set skin type, goals, sensitivities, and current actives once. Every scan is graded against that profile, not against an average user.
• Hype checks. Sus compares what the marketing claims against what the ingredient list supports — trending actives like PDRN and exosomes included.
• Plain-English receipts. Each scan returns a graded "receipt": what is flagged, what is hype, what genuinely matches your goals.

Sus is informational, not medical advice — it reads labels and gives cosmetic context; it does not diagnose skin conditions.

Which one should you use?

If you mostly scan groceries, keep Yuka — it is very good at that. If you are standing in a beauty aisle wondering whether the viral serum is right for your face, that is the question Sus was built to answer. Plenty of people will happily use both.
