L'Oreal (Paris, FR) has devised a computer controlled system for applying micro and nano cosmetic substances by a jet-spray. The systems uses a camera to image and analyze skin tones and conditions to choose the best pigment matches for a make-up look or tattoo design. After the new look is chosen, it can be seen on a computer screen and then applied to the body by ink jets than move while the subject remains still.
The L’Oreal applicator offers the advantages of freedom of design of conventional tattooing, the ease of use of a makeup operation and an average durability which may be readily controlled according to the wishes of the user, from a few hours to about 20 days. The fact that the local body characteristics are taken into account further increases the visual quality of the drawing obtained, especially to play with three-dimensional or perspective or even optical effects, enabling some skin imperfections to be made invisible.
The application of treatment products is carried out by a moving application head which follows the relief of the part while remaining a short distance away or while being in contact. The head may also comprise a powder puff, a roll or a coarse or fine brush, usually used in cosmetics.
The treatment can apply cosmetic makeup, dyeing or care products to some or all of the human body. The device is described in detail in U.S. Patent 7,648,364.
The technique of tattooing has been known since ancient times and consists in indelibly inserting dyeing substances under the epidermis. Tattooing makes it possible to obtain a color design of very high quality, but requires delicate intervention, especially in terms of health risk because of the incision of the skin. As a result, many people abandon the idea of being tattooed because of the indelibility and the surgical aspect of the operation.

Makeup products are easy to apply, but they do not stay on for more than a few hours, particularly in hot and/or humid weather. Moreover, makeup products seek to imitate the appearance of a normal skin and do not offer any freedom of design.
Small stamping pads for applying a design onto the skin by transfer printing have recently appeared. The durability of the design on the skin is of the order of a few days. However, no freedom of design is offered. The user reproduces only the design present on the stamping pad.
According to L’Oreal inventors Christophe Dauga Francis Xavier Quinn their new computer controlled application system overcomes the drawbacks associated with makeup and tattoos.
The device presents a process for treatment, especially for makeup or for temporary dyeing, without incision of the skin, capable of taking account of the local characteristics of the skin and offering a complete freedom of design.
The device comprises a means of positioning a camera over a body part, a means of taking images, a means of analyzing images in order to obtain the local characteristics of the body part, and a means of applying treatment products to that body area according to its local characteristics. The cosmetic substance applicator stays at a controlled distance from the human body part, a distance that varies from about 20 microns to about 5 centimeters;

The pigments may be white or colored, mineral and/or organic, and micrometer-sized or nanometer sized pigments. Among the mineral pigments and nanopigments, mention is made of titanium, zirconium or cerium oxides, and of zinc, iron or chromium oxides, ferric blue, chromium hydrate and ultramarines (aluminosilicate polysulfides). Among the organic pigments, mention is made of carbon black and lacquers such as calcium, barium, aluminum, zirconium or strontium salts.
