Using the sebum-absorbent tape technique, we have disclosed five different patterns of follicular sebum excretion rate (SER). These are the infantile, pubertal, acne, adult and aging patterns, distinguished by different densities of active sebaceous follicles, by distinct levels of follicular SER and by the relative stability in time of the overall SER.
Key words Acne - Aging - Image analysis - Puberty - Sebum
