Acne is a chronic inflammatory skin disorder known medically as "acne vulgaris". Because acne is experienced in puberty, it is said to be "a symbol of youth", and it is not well recognized as a disease1. However, according to a survey of the quality of life (QOL) of acne patients who visited medical institutions, regardless of the severity of the symptoms acne greatly affects a patient's quality of life2. For this reason, early stage proactive treatment and long term maintenance treatment is required1.

It supports patient self-management and promotes the continuation of treatment. Nikibi Log also provides basic information such as the mechanism of acne, along with information about makeup, skin care and related content that helps answers questions about acne and leads to a better understanding of the disease.
