Sell a curated kit of legally sourced miniature moisturizers spanning gel, lotion, and light-cream textures, paired with a guided patch-testing and wear-testing protocol. Customers record immediate comfort, hydration after several hours, irritation, and delayed congestion, then receive a non-diagnostic recommendation for the best-performing formula profile and suitable full-size options. Begin as a concierge sampling service and later develop standardized kits for common skin-response patterns.

The signals show repeated purchases across numerous prominent brands without resolution, creating both product waste and decision fatigue. Growing ingredient awareness has increased scrutiny but has not given consumers a reliable way to test complete formulations on their own skin.
