The method can further comprise calculating an amount of time that the user can be exposed to the amount of UV radiation exposed to the user's skin based on predetermined criteria. The predetermined criteria can at least include an SPF level of sunscreen applied to the user's skin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for usage of sunscreen lotions","description":"A method for calculating a rate of UV radiation absorbed by a user's skin including: capturing image data of an area of the user's skin; determining a skin tone of the user's skin based on the capture","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9816857","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
