Test anti-aging activity in a face scrub preparation that contains coffee-grade active charcoal (Coffea arabica L.) with the addition of vitamin E

Abstract

Ageing can be caused by accumulating excess dead skin cells on the skin's surface. Coffee grounds are a by-product of the coffee brewing process. Coffee grounds can be used as activated charcoal in face scrub preparations. The purpose of this study was to formulate and test the effectiveness of anti-ageing face scrub preparations of coffee grounds activated charcoal (Coffea arabica L.) with the addition of vitamin E. Material and methods: the research method includes processing coffee grounds in the form of drying and making activated charcoal, then formulating into face scrub preparations with a concentration of 1 %; 2 %, 3 % with vitamin E, 5 % and without vitamin E and blanc (without activated charcoal). Evaluation of face scrub preparations includes homogeneity test, stability test (odour, colour, pH and consistency), cycling test, dispersion test, viscosity test, centrifugation test, hedonic test, irritation test, and effectiveness test (moisture, pores, stains, wrinkles) on facial skin using a skin analyser on 24 volunteers with application to the face once a week for 4 weeks. The experimental data were analysed using the SPSS 22 program. Results: they showed that all face scrub preparations were in the form of cream with grey-black granules, coffee-scented, homogeneous, stable for 12 weeks of storage at room temperature (20-25°C), pH value (5.0-6.0), had a spreading power of 5-7 cm, viscosity (3760-3996 mPa's), no separation occurs in the centrifugation test and does not irritate facial skin. The results of the hedonic test, the most preferred formulation, was the F3 preparation. The effectiveness test results were an increase in humidity of 27 %, a decrease in pore size of 35.8 %, stains of 40 % and wrinkles of 37.6 %. Conclusion: from the results of the study, it can be concluded that the face scrub preparation of activated charcoal coffee grounds (Coffea arabica L.) with a concentration of 3 % and vitamin E 5 % is a formula that meets the evaluation of the preparation and measures the effectiveness of anti-ageing
