本研究可鑑定台灣女性膚質因年齡漸增老化過程中，在每個年齡層明確的膚質變化，於發展化粧保養產品訴求上，提供特定年齡層的需求時有更確切的目標。 The cost on the cosmetic maintenance articles in Taiwan are up to NT$60~80 billion a year, but the market share of cosmetics produced locally in Taiwan is low. The cosmetics imported from abroad generally resort to the high efficiency but neglect the skin properties applicability of the Taiwanese consumer. Although there are related cultural investigations concerning Asia female skin properties research, they are mainly confined to Japan and Korean local areas. Considering the fewer documents related to local Taiwan female, this research primarily focused on inquiring into Taiwanese people who are various from age female skin properties.
The subjects in this study are 130 Taiwan females, ranging from the age of 5 to 59. They are divided into six groups, with 10 years as an age layer. Furthermore, we chose two sites of skin which is very different in the properties and carrying on skin properties identification. Through this approach, we can find out the relations between ages and skin properties.
Our results showed that the secretion of skin surface sebum in the group of the age from 5 to 9 is relatively low. The secretion will be on the rise in the group from 40 to 49, the age of reaching the menopause. The skin surface sebum secretion on the forehead and the cheek shows the biggest difference in the group of the age from 30 to 39. The stratum corneum hydration in the group of the age from 5 to 9 is higher. With the coming of the adolescence, the stratum corneum hydration will slowly decrease in the group of the age from 50 to 59 will down to the lowest. The stratum corneum hydration on forehead and the cheek shows the biggest difference in the group from 40 to 49, the age reaching the menopause. The pH value of skin surface in the group of the age from 5 to 9 is also relatively low. The pH value will be on the rise in the group from 40 to 49, the age of reaching the menopause. The skin surface pH value on the forehead and the cheek shows the biggest difference during the age of 5~9.
This research can provide the evidence for the design of cosmetic maintenance articles for Taiwanese female. The skin properties differ at different age ranges. When developing the claim to the cosmetics products, we can focus on providing the need of the particular age layer with more understanding of the explicit skin properties variations.
