About this study

Official title: The Effect of Cosmetic Products Containing Assam Tea (Camellia Sinensis Var. Assamica) Extracts on Irritation, Moisturization, Skin Elasticity, Wrinkles, and Satisfaction in Volunteers.

Thailand has entered an aging society, prompting increased research on improving the elderly quality of life and preventing age-related diseases, with a particular focus on skin aging. Skin aging is linked to the degradation of dermal and epidermal tissue, leading to decreased collagen, elastin, and glycosaminoglycans, which causes reduced skin elasticity and wrinkles.

Assam tea is native to northern Thailand and is traditionally used in local products like fermented "Miang." Research shows that Assam tea contains high levels of polyphenols, particularly catechins, which have strong antioxidant properties that help combat conditions such as cancer, cardiovascular disease, and skin aging.

The study aims to study the effect of cosmetic products from Assam tea on irritation, moisturization, skin elasticity, wrinkles, and satisfaction in volunteers to enhance its value, particularly for the elderly. This effort is intended to boost the local economy, promote community-based tourism, and expand Assam tea products to national and international markets, ultimately improving livelihoods and addressing environmental concerns in northern Thailand.
