Food scanner and cosmetic scanner FAQ.

What can Lychee scan?

Lychee scans packaged food products and now supports cosmetic and beauty product scanning, including skincare, makeup, haircare, deodorant, fragrance, sunscreen, and other personal care labels.

Does Lychee replace reading the product label?

No. The physical package is the source of truth. Barcodes, databases, OCR, and AI explanations can be wrong or outdated, and formulas can change.

How does Lychee calculate a food score?

Lychee uses label-based signals such as ingredients, additives, allergens, processing cues, and source context. A score is a summary, not a complete judgment of whether a food is safe or appropriate for a specific person.

How does cosmetic scanning work?

Lychee reads cosmetic ingredient labels and explains common ingredient roles and concern categories. Beauty scans require extra caveats because concentration, exposure, frequency of use, and personal sensitivity usually are not visible on the label.

Is a flagged cosmetic ingredient always harmful?

No. A flag means an ingredient may deserve attention for some users or contexts. It does not prove harm in a finished product or at a specific concentration.

Can Lychee diagnose allergies or skin conditions?

No. Lychee can help you notice label terms, but it cannot diagnose food allergies, contact dermatitis, acne triggers, rosacea triggers, or other medical conditions.

What sources does Lychee reference?

Lychee pages link to public references such as Open Food Facts, USDA FoodData Central, FDA food and cosmetics pages, EFSA food additive resources, WHO IARC Monographs, European Commission CosIng, and Open Beauty Facts.

What happens if a product is missing or incorrect?

Coverage varies by product, country, barcode, and database freshness. If a product is missing or looks wrong, check the label directly and treat the scan as incomplete.

Does Lychee use AI?

Lychee may use AI-assisted explanations to make labels easier to understand. AI text is not a primary source, and important decisions should be checked against product labels, source links, and professional advice.

Is Lychee a diet app?

Lychee is focused on label transparency and ingredient context. It is not a weight-loss plan, meal plan, medical device, or substitute for a dietitian.
