Description

Oil-to-form Type Cleanser Composition Having Two Layers

The present invention relates to an oil-to-foam type two-layered face wash composition.

As interest in skin increases, interest in face washing is also increasing. It is a good example of the importance of washing face that the facial cleansing methods of female celebrities with good skin, such as Go Hyun-jung's fluffy facial cleansing method and Lee Min-jung's mist washing method, became a hot topic. Depending on the person, there may be a face-washing method that suits them, but the double face-wash method is usually emphasized. The reason that double cleansing is emphasized is that the first cleanser alone leaves behind cleanser or makeup residues, and the second cleanser alone does not dissolve all makeup, which reduces the cleaning ability. Therefore, as the primary face wash, cleansing oil, cleansing water, and cleansing cream that can dissolve makeup are used, and as the second face wash, the primary face wash and a cleansing foam that can wash off makeup residues are used. This double-washing has the advantage of maintaining clear and bright skin, but has the disadvantage of being cumbersome to wash twice.

Therefore, if there is a face wash that can act as both the primary and secondary face wash at the same time, it will be possible to protect the skin while compensating for the disadvantage of being cumbersome.
