The present invention relates to a cosmetic composition and a method for preparing the same.

The skin is a very important tissue that protects the human body while in direct contact with the external environment and has biochemical and physical functions. This tissue is largely divided into three types, namely, the epidermis, dermis, and subcutaneous tissue. The color of human skin varies depending on the number, size, type, and distribution of melanosomes containing melanin in skin cells.

According to the influence of stress, ultraviolet rays, environmental pollution, etc., the skin condition is affected, and the skin condition has a great effect on the beauty and impression, so there is a growing interest in cosmetic compositions that can improve whitening and aging.
