An imaging apparatus includes: determination means for determining whether a capture image is a frontlit image or a backlit image; detecting means for detecting a flesh-color area in the capture image; calculation means for setting weights, in a luminance histogram on the flesh-color area, on luminance of pixels included in a high-luminance area having a relatively high luminance value and luminance of pixels included in a low-luminance area having a relatively low luminance value in accordance with the determination result, and calculating modified luminance produced by modifying luminance on the flesh-color area on the basis of the weights; and correcting means for correcting brightness of the capture image on the basis of the modified luminance.

The present invention relates to in vitro methods for determining efficacy of topical compositions on various skin color types. These methods involve providing an artificial skin apparatus configured to approximate the color and diffuse reflectance characteristics of a predetermined human skin color type. The artificial skin apparatus includes an artificial skin substrate combined with a color background, with the color background correlating to the human skin color type. A topical composition of interest is applied to the artificial skin substrate of the artificial skin apparatus and then pre-irradiated. The pre-irradiated topical composition is then analyzed using relevant experimental techniques or assays for at least one efficacy parameter, including, for example, anti-ageing, photoprotective, sun protective, UVA/UVB protective, UVAI protective, photo stabilizing, and photosensitizing activities and action mechanisms of the topical composition on various skin color types. Also provided is an artificial skin apparatus and kit for use with the in vitro method.

The invention discloses an agent for multidimensionally removing freckles and acne marks and evening skin tone. The agent is prepared from, by weight, 0.1-0.2 part of allantoin, 2-6 parts of a turmeric root fermentation extract, 0.05-0.3 part of dipotassium glycyrrhizinate, 2-5 parts of niacinamide, 0.5-2 parts of D-panthenol, 0.05-0.2 part of tea tree oil, 0.1-0.2 part of fullerene and 0.05-0.5 part of oryzanol. Through the composition, the acne mark problem can be solved multidimensionally, and the skin whitening effect can be achieved; in the first dimension, acne is subjected to inflammation diminishing treatment through the anti-inflammation and anti-oxidation effect, and thus acne which grows out is quickly healed; in the second dimension, the transepidermal moisture loss of the skin is reduced, the barrier effect of the skin is repaired, the self-repair capability of the skin is restored, the resistance of the skin is enhanced, and thus the acne occurrence frequency is reduced; in the third dimension, the generation of fatty acid and triglyceride in sebum is reduced, so that pores are shrunk, and the acne occurrence severity is reduced.
