Abstract

The market of skin lightening product grows very fast. This is especially true in almost all Asian countries. Martha Tilaar Innovation Center has found natural ingredients which function as anti oxidant and anti tyrosinase in vitro. These ingre-dients are extracted from Indonesian plants namely Lansium domesticum (LE)*) and Phyllantus niruri (PE) *). Several aspects should be considered to utilize these ingredients in cosmetic, such as, the stability of the plant materials and their safety and efficacy on human skin. The objective of this research is to study whether these ingredients in cosmetic preparations have skin lightening and skin moisturizing effects clinically. This article will describe the safety and efficacy evaluation on natu-ral ingredients extracted with ethanol from the above Indonesian plants. The safety evaluation is conducted clinically using Repeated Opened Patch Test (ROPT) and followed by Single Closed Patch Test (SCPT) in more than 50 selected healthy volun-teers. Their irritation properties on mucous membrane were evaluated using HETCAM method. Then, their efficacies on lightening and moisturizing were conducted in more than 26 volunteers, using Mexameter MX 16 and Corneometer CM 820. These results revealed that both extracts are safe on human skin and mucous membrane and can function as skin lightening agent. Lansium domesticum extract also has skin moisturizing effect.

Abstract

An accumulation of fat in the subcutaneous tissue causes cellulite and dimpling on the surface of the skin. Although not related to obesity, obesity worsens cellulite. There are abundant topical anticellulite creams on the market, but the efficacy of these creams has not been scientifically proven. A combination of Centella asiatica L. leaves extract and green coffee (Coffea canephora robusta P.) bean extract in a cream preparation was clinically tested in 30 women for 84 days in the absence of diet and exercise. The descriptive-true experimental before (T-0)-after (T-84) method was used to classify the cellulite (grade 1–3) and to determine the slimming effect. The cellulite appearance and the body circumferences (abdominal and thigh) perimeters were photographed 5cm and 10cm below the navel and below the gluteal fold. The results of before and after the treatment showed that grade 1 cellulite lower (p < 0.000), the measurement of abdominal circumference showed reduction (p < 0.013), but the measurement of both thigh circumference showed insignificantly reduction (p < 0.512). The combination of both extracts reduce cellulite and fat deposits in the abdominal area, making the volunteers look slimmer
