BACKGROUND/AIMS Facial sebum secretions are known to change under various circumstances. [...] Key Method Sebum secretions were measured at five sites of the face seasonally for a year, in the same volunteers. Using the data obtained we developed a set of rules to define the combination skin type. RESULTS Regional differences in sebum secretion were confirmed. Sebum secretions on forehead, nose, and chin were higher than on both cheeks.Expand

Two possible classifications of facial skin type by two parameters in Korean women: sebum excretion rate (SER) and skin surface relief (SSR)
TLDR
This study suggests two possible classifications of facial skin type by using simple methods to solve the problem of consumers not knowing which products are suitable for their skin because they don't know their skin type exactly. Expand

The purpose of the study was to measure skin biophysical parameters non‐invasively on healthy subjects living in Valais, and to correlate the measures with their life style. Expand
Anatomical variation in the amount and composition of human skin surface lipid.
TLDR
The results indicate that lipid produced by the epidermis is an insignificant fraction of the total extractable surface lipid on areas rich in sebaceous glands, but can affect surface lipid composition on the limbs and on the trunk away from the midline. Expand
EEMCO Guidance for the in vivo Assessment of Skin Greasiness
TLDR
A better understanding of factors that alter the sebum amount at the skin surface may well assist in the development of sebosuppressive agents to help the reduction of the skin greasiness and improve acne. Expand
Seasonal modulation of sebum excretion.
TLDR
The Sebutape technique has confirmed that ambient temperature influences the sebum excretion rate, which is related to an increased delivery of sebum to the surface of the skin without an increment in the number of active sebaceous follicles. Expand
Sustainable rates of sebum secretion in acne patients and matched normal control subjects.
TLDR
All subjects with acne had secretion rates larger than those of their matched control subjects, indicating that a high sebum secretion rate is the decisive factor in inflammatory acne. Expand
