Abstract

The invention provides a composition for whitening and removing freckles. The composition comprises following active components in parts by weight: 1-5 parts of tranexamic acid and 0.5-2 parts of ascorbate, wherein the structural formula of the ascorbate is shown as the specification, wherein R1, R2, R3 and R4 are C10-C20 alkyls; and the alkyls are selected from aromatic hydrocarbon groups and/or aliphatic groups. The composition has good effects of banishing the freckles, removing the freckles and whitening and can be used for chloasma, the freckles, age pigments, aestates and the like, has obvious effect aiming at the chloasma, and is stable and controllable; and meanwhile, an external preparation prepared from the composition provided by the invention can be used for a wounded part, and has fast effect, good curative effect and small toxic or side effect.

Description

Technical field [0001] The invention relates to a composition for whitening and removing freckles, in particular to a composition for whitening and removing freckles and a preparation thereof that can be used externally. Background technique [0002] Pigmentation refers to spots that are different in color from the surrounding area. It appears because of the increase in skin pigmentation, causing small spots such as black and yellowish brown on the skin.
