The invention discloses an anti-freckle skin care product, which is prepared from the following ingredients including phenylethyl resorcinol, 4-butyl-resorcino, 1-methylhydantoin-2-imide, paeonol, paeonol derivatives and oat alkaloid derivatives. In the skin care product, the phenylethyl resorcinol, the 4-butyl-resorcino, the 1-methylhydantoin-2-imide, the paeonol, the paeonol derivatives and theoat alkaloid derivatives are compounded; the generation of melanin can be effectively inhibited; the pigment sedimentation can be reduced. Meanwhile, through the anti-oxidization capability of the paeonol, the oxidization of ingredients of the phenylethyl resorcinol and the like can be effectively inhibited; the product stability is improved. Through the anti-inflammatory and anti-stabbing-pain effect of the oat alkaloid, the irritation caused by the phenylethyl resorcinol derivatives can be effectively relieved; the product is mild and non-irritative on the skin. Compared with the existing anti-freckle product, the anti-freckle skin care product has the more obvious effect in aspects of freckle removal and whitening. The freckle can be fundamentally removed; the freckle generation can beprevented; the product is mild and non-irritative on the skin.

The invention provides a skin-whitening functional composition and an application thereof in cleaning skin care products. The skin-whitening functional composition includes fresh milk, a cruciferous plant whitening essence and a vitamin composition which includes one or more selected from: vitamin E, vitamin C, vitamin B3, vitamin B5 and vitamin B6. The biggest difference between the composition and a conventional skin-whitening agent is that the composition has the two following effects: 1) the composition can be decomposed directly to reduce skin melanin which is formed already; and 2) the composition can inhibit the activities of skin melanin cells and tyrosinase, thereby preventing excessive generation of the skin melanin. The composition, among other skin-whitening products, can more directly and quickly whiten skin and remove stains.

The present invention relates to a skin external composition comprising an extract of the flower and fruit of paper mulberry, and more particularly to a skin external composition containing, as an active ingredient, an extract of flower and fruit of paper mulberry, which shows an excellent skin-whitening effect by effectively inhibiting melanin production.
