ABSTRACT:
A method is provided for obtaining a customized skin foundation product to cover human skin imperfections. The steps include spectrophometrically measuring a customer's normal skin to obtain normal skin coloration values of lightness, redness and yellowness respectively denoted as L, a and b units. Thereafter the normal skin coloration values are converted through calculation to a modified value determined by a set program correcting L, a and b values. Based on the modified value the next step is formulating a facial foundation having color pursuant to the modified value. Adjustments are provided for redness and yellowness according to a set of schedules determined by the b/a ratio. Normally the measurement and skin imperfection determination are performed by a licensed dermatologist. Formulation and adjustment is is conducted at a site remote from the dermatologist office or place where the customer is measured and evaluated. Most preferred is the use of a formulation machine at the remote location to convert instructions received about a customer's modified formulation to dose and blend a series of cosmetic chemical compositions containing various monochromatic colors and skin benefit agents. The optimal formula dosed from the machine is packaged and then shipped to the customer.
