What about the formulation?
Lychee puts processing at the heart of its food score. Additives, ingredient quality and nutrition still matter, so a protein claim does not tell the whole story.

that name mean?
Understand surfactants, humectants, emollients, preservatives, colorants and fragrance terms. Unknown ingredients stay visible.

Rinse it off.
Or leave it on?
A cleanser and a moisturizer are used differently. Product type and exposure shape the cosmetic analysis; a label does not report every concentration.

Enough information
comes first.
When ingredient coverage is too low, Lychee shows Not enough data. You can still review recognized ingredients and inspect the gaps.

A useful result.
With its limits in view.
Food lookup uses Open Food Facts; beauty lookup uses Open Beauty Facts. Lychee applies its own scoring logic and ingredient dictionaries. Records can be incomplete or outdated, so the package in your hand still matters.

Before your

How does Lychee score food?
Lychee uses a 1–100 food score that prioritizes processing. Additives, ingredient quality, sugar, salt, saturated fat, fiber and protein also matter. Available NOVA data and ingredient-based estimates inform processing; Lychee applies its own scoring rules. Missing data can reduce confidence or prevent a score.
Does Lychee scan cosmetics and skincare?
Yes. Lychee scans beauty and personal-care barcodes and ingredient labels. Its beta cosmetic score considers recognized ingredients, concerns and exposure, including rinse-off versus leave-on use. It shows Not enough data when ingredient coverage is insufficient.
Can Lychee check food allergens?
Lychee helps compare available ingredient, allergen and trace information with a selected profile. It cannot guarantee that a food is allergen-free or detect undeclared cross-contact. Always read the current label and follow your allergy care plan.
What if my product is missing from the database?
Try reading the ingredient label with Lychee. You can also submit or correct product data through its contribution flow. OCR and contributed records need checking; a missing ingredient list should be treated as incomplete data.
Does Lychee work offline?
Previously saved product information can be available from local history or pantry data. New barcode lookups need network access; failed scans can be queued for retry. Offline access is not a complete offline product database.
