Skincare brand Kiehl's is rolling out its ‘Apothecary Preparations' concept worldwide.

The in-store service offers personalized skincare solutions that involve creating a unique blend of concentrates for each customer.

The first step of the process is a skin consultation, which is carried out using the dermatologist-inspired tool ‘Skin Atlas'. The second is the selection of two essential ‘Targeted Complexes' -- which the brand refers to as "pharmaceutical-meets-herbal concentrates" -- which are to be used alongside the ‘Kiehl's Skin Strengthening Concentrate.'

Options include complexes to tackle wrinkle reducing, texture refining, visible redness neutralizing, pore minimizing and brightening. The concentrate is designed to be mixed and activated by the customer at home, and comes packaged in a personalized box including the client's name, details of the formula and directions for use.

According to Kiehl's Head Chemist Dr. Geoff Genesky, the Skin-Strengthening Concentrate is composed of a 35% concentration of Squalane and a Skin Lipid Complex at 20%, which within the formula fortifies, hydrates and helps protect the barrier for healthier skin. "This powerful special blend of efficacious yet gentle ingredients has been clinically validated to strengthen the skin barrier after just one hour of use," he says.

Bespoke beauty is becoming an increasingly popular concept, with brands such as Skin Inc, Le Labo and Novel Beauty just some of those that have built their reputations on personal touches that allow consumers to engage more directly with the products they purchase.
