X-Beauty: Green Chemistry Campaign

Korea International School, Jeju ChemClub

Greetings from ChemClub at Korea International School in Jeju, South Korea! Our ChemClub was created more than a year ago, but this is the first time sharing our news.

X-Beauty: Green Chemistry was the focus of an event on November 19, 2014. Our Club invited a certified cosmetician to speak to the group about “Jeju Green Tea: Healing & Beauty Ingredients.” After learning about Jeju green tea as an ingredient, students made their own green tea hand cream with eco-friendly ingredients.

Why green tea?

Components of green tea include polyphenols, which are well-known antioxidants. Most of these polyphenols are classified as catechins. They are thought to help retard skin’s aging and protect skin from sun exposure. Green tea has been used as an ingredient in anti-aging products as well as sunscreen skin products.
