A transverse closed-loop fiber resonator (10) includes an inner cladding (102) having a surface (300) peripherally forming a closed-loop shape for confining light to the surface (300). The inner cladding has a first diameter thickness (104) and a first index of refraction profile in a cross-sectional portion of the transverse closed-loop fiber resonator (10). A ringed-core (120) corresponding to the closed-loop shape is disposed on the corresponding surface of the inner cladding (102). The ringed-core (120) has a second thickness (124) of material thinner than the first diameter thickness (104), and a second index of refraction profile greater than the first index of the inner cladding by an index delta in the cross-sectional portion of the transverse closed-loop fiber resonator such that the ringed-core can guide light within the ringed-core traversely around the closed-loop shape.

Luminous fluxes from a xenon tube are introduced from one end of an optical fiber to an other end thereof and emerge therefrom. These luminous fluxes are incident of a skin of a person to be measured, and those diffused in the skin are incident on one end of an optical fiber through a first incident port and on one end of an optical fiber through a second incident port. The luminous fluxes from the one end are split by a dichroic mirror. The luminous fluxes reflected by the dichroic mirror are received by a photoelectric conversion element via a blue filter, and those having transmitted through the dichroic mirror are received by a photoelectric conversion element via a green filter.

The invention relates to a method and a process of determining individual skin structure and function at a point in time for the purpose of determining and formulating skin care products that remedy the deficiencies observed in the skin. Objective and repeatable dermal biometric instrumentation techniques can be used to measure skin moisture content, sebum content, firmness and elasticity properties, skin thickness, transepidermal water loss, skin pH and to perform a photo analysis of the face with UV and visible light. By customizing the skin care products, the individually added active ingredients can be controlled, the diluents can be modified, dermal penetration rates can be controlled, the surfactant systems can be adjusted, and the stability of the product can be controlled. To prevent the loss of active materials in the product, the skin care product is manufactured for an individual consumer and is only sold in a quantity of a three months supply. Additionally, a variety of ingredients can be combined that a mass produced product cannot contain due to stability/compatibility issues. This invention overcomes the limitations in formulating skin products for the mass market by providing a product designed with objective biometric data and created for the specific clinical condition of an individual's skin.
