[0178] (test using cream)

[0179] Each of the creams of Examples 1 and 2 and Comparative Example 1 was applied to the periphery of each eye of 20 women (25-45 years old) in the evening once a day. Administered continuously for 2 months. Then, based on the evaluation criteria shown in Table 2, the skin color improving effect in terms of dark circles was evaluated.

[0180] [Table 2]

[0181] evaluation score evaluation standard 1 The skin around the eyes was bright, and no dark circles were observed. 2 The skin around the eyes is slightly darkened, and dark circles are slightly observed. 3 The skin around the eyes is dark, and dark circles are observed. 4 The skin around the eyes is dark, and dark circles are prominent.

[0182] Then, the skin tone improving effects of the creams of Examples 1 and 2 and Comparative Example 1 were summarized. Before the use of the cream and two months after application, the case where the difference in ...

Abstract

A tocopherol phosphoric acid ester represented by a following formula (1) (in the formula, R1 , R2, and R3 each independently represents a hydrogen atom or a methyl group.), a pharmacologically-acceptable salt thereof, or a solvate thereof for use in the improvement of skin color.

Description

technical field [0001] The present invention relates to skin tone improving agents and compositions for improving skin tone. This application claims priority to Japanese Patent Application No. 2014-176524 filed on August 29, 2014 and Japanese Patent Application No. 2014-187719 filed on September 16, 2014. The content of the above application is incorporated herein by reference. Background technique [0002] Dark circles around or under the eyes are known to develop due to various factors such as aging, pigmentation from blood or melanin, blockage of blood flow, and reduction and structural changes in collagen fibers (see eg NPL 1). [0003] For skin tone improvement including dark circles, administration of whitening agents such as vitamins, administration of blood flow enhancers such as plant-derived saponins, treatments for improving blood flow such as use of massage, etc. are known to be effective. However, the details of the mechanism of generation of dark circles and ...
