Product databases
Helpful for barcode lookup and label fields, but they may lag behind formula changes or contain contributor errors.
Food References
Food scanner sources are useful, but not identical.
Some sources describe a product label. Others describe nutrient composition, additive regulation, toxicology review, or cancer-hazard classification. Lychee presents these as context, not as a single proof that a food is good or bad for every person.
Cosmetic References
Beauty scanning needs regulatory and exposure caveats.
Cosmetic labels often use INCI names and may group fragrance components under terms such as fragrance or parfum. A scanner can explain ingredient roles and known concern categories, but concentration and use pattern are usually not visible from the ingredient list alone.
How To Interpret Sources
One source rarely answers the whole question.
Regulator pages
Helpful for legal status and safety frameworks, but rules differ by country and may not address every personal health concern.
Hazard references
Helpful for identifying concern categories, but hazard alone does not establish real-world risk at a specific dose or concentration.
Attribution and limitations
When Lychee uses or references open data, the app and pages should preserve source attribution and license requirements. Lychee summaries should be checked against product packaging, manufacturer guidance, and professional advice for medical, allergy, pregnancy, child-safety, or dermatology decisions.
