FORMULASI DAN UJI AKTIVITAS ANTIOKSIDAN SEDIAAN SERUM EKSTRAK ETANOL BIJI KOPI HIJAU (Coffea canephora pierre)

Abstract

The use of natural ingredients in cosmetics to prevent premature aging caused by exposure to ultraviolet radiation is becoming a popular trend in Indonesia. The bad effects of exposure to ultraviolet radiation can cause the skin to lose its elasticity and premature aging which is characterized by sagging, thinning, dry skin, the appearance of black spots on the skin, hyperpigmentation, fine lines and wrinkles. One of the plants that can be used to make natural cosmetic ingredients is green coffee beans (Coffea canephora pierre), where green coffee beans contain alkaloids, tannins, phenolics, flavonoids, triterpenoids and glycosides which are believed to be antioxidant agents. Green coffee beans (Coffea canephora pierre) have poor solubility, so serum preparations were chosen to be able to deliver active compounds quickly and effectively to the skin. The method for checking antioxidant activity used in this research was carried out using the DPPH (2,2 -diphenyl-1-picrylhdrazil) method
