Offer asynchronous routine audits delivered by a licensed esthetician or similarly qualified professional. Customers submit their products, skin concerns, sensitivities, and routine; they receive a plain-language compatibility review, a simplified morning and evening plan, a gradual introduction schedule, and clear guidance on when to consult a dermatologist. Begin as a fixed-price service and later productize recurring check-ins and structured ingredient screening.

Consumers have access to increasingly complicated active ingredients and trend-driven products, but the signals show growing uncertainty about how to combine them safely. A human-reviewed service can launch immediately without developing clinical software or carrying inventory.
