Description

  The present invention relates to a powder cosmetic and a method for using the same.

  Conventionally, in a general makeup method, a foundation is applied after applying a base cosmetic. However, since the foundation cosmetics are difficult to dry and are easily sticky, there is a problem that when the foundation is applied thereon, the foundation cannot be applied uniformly and unevenness tends to occur. In order to solve such problems, a foundation that is smooth and easy to apply and has improved usability has been developed (Patent Document 1). However, the conventional makeup method has a problem that makeup collapse such as twisting and shining easily occurs due to the foundation absorbing sebum over time.

  On the other hand, in order to prevent breakup of the makeup, by applying powder cosmetics for retouching over the foundation, it prevents shine and stickiness, produces a transparent skin color with a mat, and suppresses sweat and sebum, It is done to improve makeup. However, when the powder cosmetic is applied from above the foundation, there is a feeling of burden and pressure on the skin over time, and it is difficult to obtain a sufficient makeup effect.
