Abstract

The invention relates to a skin-brightening spot-fading essence. The essence comprises the following components in percentages by mass: 1-5% of isopropyl myristate, 1-5% of caprylic / capric triglyceride, 0.1-10% of a skin-brightening spot-fading composition, 1-10% of a moisturizing agent, 1-6% of an emulsifier, 0.1-1% of a thickener, 0.01-0.1% of a preservative, 1-5% of polydimethylsiloxane and 60-70% of deionized water, wherein the skin-brightening spot-fading composition is composed of 10-22 parts of elderberry extract, 3-8 parts of artemia extract and 5-12 parts of ceratonia siliqua germ extract. The main active ingredient of the skin-brightening spot-fading essence provided by the invention is formed by compounding elderberry alcohol extract methyl acetate extract, elderberry alcohol extract n-butanol extract, the artemia extract and the ceratonia siliqua germ extract. Tests prove that the spot-fading essence provided by the invention can significantly improve chloasma, hormone spots caused by hormone withdrawal, and post-inflammatory pigmentation.
