J Dermatological Treatment 30(4).Over decades, we have reviewed, with patients and consumers, few to dozens of cosmetics and skin care products they have discarded either due to a suspected allergy or because the products were believed to not be suitable for their skin, based either on intolerance and/or lack of efficacy. This ambiguity encourages the development of tools to assist in product personalization, which has thrived among cosmetic companies.
With no-expertise-required diagnostic and non-invasive devices, cosmetic brands train technicians to assess customers’ skin and/or hair, which then provides a measurement to aid in product selection.
