Abstract
Sebum secretion from sebaceous glands plays an important role in the protection of skin because of its wettability, lubricity and film-formation. Therefore, decrease of secretion amount of sebum causes an chapped-skin and a fissure. On the other hand, it is reported that excessive secretion of sebum stimulated a sticky feeling on skin, a formation of comedo and a negaive effect to skin by peroxylipids. Furthermore, make-up film deterioration by sebum must be considered as influence on makeup products. Almost all cosmetic users do NOT satisfy to “long-lasting” effect of currently available make-ups, therefore, the relationship between make-up film deterioration and secretion sebum is extremely use for formulation of cosmetics. In this report, some properties of secretion sebum is shown at former part, and then, countermeasure methods against sebum as make-up ingredient is introduced at latter one.
