Description

The present invention relates to a lipstick cosmetic. Specifically, it relates to a multicolor lipstick cosmetic. More specifically, the present invention relates to a multicolor lipstick cosmetic that can produce a finish that is simple, youthful and brilliant without requiring special techniques.

Conventionally, various lipstick cosmetics and evaluation methods have been developed in order to produce a beautiful or youthful impression of the lips. For example, in Patent Document 1, by blending iron oxide-coated mica titanium whose transmission interference color is blue and green and reflection interference color is red and whose appearance color is skin color, maintaining a natural lip with a transparent feeling, A method for providing a lipstick cosmetic composition that makes lip wrinkles inconspicuous has been reported. Patent Document 2 reports a method for determining the chromatic youthfulness of the lips using the difference between the a * value and the b * value in the L * a * b * color system of the lip image taken by the camera as an index. Yes.

On the other hand, various application techniques are devised every day by makeup artists to control the texture and impression of lips using lipstick cosmetics. For example, a technique is known in which one lipstick cosmetic is applied to the entire lip using a plurality of lipstick cosmetics, and another lipstick cosmetic is applied to the center of the lip.

However, since the texture and impression of the lips are strongly influenced not only by the average color and average texture of the lips, but also by how the color changes on the lips, the lips have a uniform color and texture. The conventional lipstick cosmetics to be controlled and the evaluation method thereof have not been sufficient. In addition, the control of the texture and the impression by the technique that makes full use of a plurality of lipstick cosmetics has a problem that the user requires a high degree of skill and is troublesome.

On the other hand, the lips have a pale color due to aging, the transparency becomes low, and the youthful appearance is impaired. In other words, it is possible to give the lips a youthful appearance by directing the lips to a finish that looks like a bloody color. Here, the bloody color can be defined as the intensity of redness, more specifically, the height of the a * value in the L * a * b * color space. On the other hand, transparency is known to be caused by various factors. For example, in Non-Patent Document 1, various elements that cause transparency are reported, and due to the demonstration using a cube, transparency occurs due to the presence of chroma gradation on the surface. It is shown. In other words, by combining a strong reddish color and a saturation gradation, it is possible to express both the ruddyness and the translucency, and it is possible to produce a finish that is transparent to the ruddy. However, an example in which such a combination is applied to lipstick cosmetics has not been reported, and how it can be realized has been unknown.

JP 2001-288039 A Japanese Patent No. 5185142 “Low-Level Image Cues in the Perception of Transient Materials”, ROLAND and HEINRICH, ACM Transactions on Applied Perception, Vol. 2, no. 3, July 2005, P346-382.

This invention is made | formed in view of this situation, The objective is to provide the lipstick cosmetics which can produce the finish that the blood color was transparent easily without requiring a special technique.

In order to solve such a problem, the inventors of the present application are characterized in that at least three kinds of lipstick cosmetics having redness or concealment are arranged in a certain direction, and the redness or concealment is different in stages. The present inventors have found that multicolor lipstick cosmetics can produce a finish with a clear blood color without requiring a special technique, and have completed the present invention.

The multicolor lipstick cosmetic of the present invention has an effect of attaching at least three kinds of lipstick cosmetics separately from the inside of the lip to the contour because at least three kinds of lipstick cosmetics are arranged in a certain direction. There is no need for special techniques for rendering the colors in stages. In addition, since the redness or concealment degree varies stepwise, it has the effect of rendering the lips with a strong reddish color and saturation gradation, producing a youthful and transparent finish. be able to.

It is a conceptual diagram which shows the makeup | decoration method of this invention. It is explanatory drawing which shows the manufacturing method of an example of the lipstick cosmetics of this invention. It is an example of the lipstick cosmetics of this invention. It is explanatory drawing which shows the colorimetry method of an Example.

The multicolor lipstick cosmetic of the present invention is a multicolor lipstick cosmetic in which at least three kinds of lipstick cosmetics having redness or concealment degree are arranged in a certain direction, and the redness or concealment degree is stepwise different.

The redness and concealment degree can be controlled, for example, by changing the ratio of the red pigment contained in the lipstick cosmetic or by blending a certain amount of white pigment. Specifically, for example, the higher the ratio of the red pigment contained in the lipstick cosmetic, the stronger the redness and the higher the degree of concealment. In addition, as the white pigment is blended and the blending ratio is increased, redness can be reduced while increasing the degree of hiding. Further, the lower the pigment ratio, the lower the concealment degree.

As shown in FIG. 1, the multicolor lipstick cosmetic of the present invention is strong enough that the redness is gradually increased to the inside of the lip by attaching at least three kinds of lipstick cosmetics separately from the inside of the lip to the contour. It is characterized by being able to be applied so as to be weaker as it is closer to the contour side. This feature can be realized by changing the redness or the degree of concealment stepwise.

The multi-color lipstick cosmetic of the present invention calculates the difference between the a * value in the L * a * b * color space as the difference in redness between the inner part and the contour part of the lip, and after application, It can be selected as a judgment criterion that the Δa * value in the finish has an effect higher than the Δa * value of the lips to which nothing is applied. As a method for calculating the Δa * value, for example, the lip coated with the lipstick cosmetic is photographed with a digital camera or the like, the pixel value is converted into an L * a * b * color space, and the inner part and the contour part of the lip It is possible to adopt a method of calculating the difference between the a * values of Further, as the redness difference, in addition to the Δa * value, a ΔC * value that is a difference between C * values in the L * C * h color space, a ΔS value that is a difference between S values in the HSV color space, and the like are generally used. Various saturation values can also be employed. As the colorimetric part, either the upper lip or the lower lip can be selected, but it is more preferable to select the lower lip, and in the horizontal direction, both the mouth corner area and the central area are selected. Although it can be selected, it is more preferable to select the central region.
