Abstract

The invention provides sunscreen and after-sun repairing skin care composition and a cosmetic containing the same. The composition comprises a rhEGF (recombinant human epidermal growth factor), hydrolyzed soy protein, purslane herb extract, Chinese magnoliavine fruit extract and rhizoma kaempferiae extract. The weight content of the composition in the cosmetic is 1%-2%. The weight content of the rhEGF in the sunscreen cosmetic is only 1-10 mu g/ml and is far lower than the conventional addition amount, the rhEGF is compounded with the hydrolyzed soy protein, the purslane herb extract, the Chinese magnoliavine fruit extract and the rhizoma kaempferiae extract to realize synergistic effect, so that injured cells can be rapidly repaired, skin injury caused by ultraviolet radiation is relieved, further, abnormal increase of melanophores of a skin basal layer can be reduced, melanin synthesis is blocked, black spots growing on the after-sun skin are reduced, gene mutation factors of the injured cells are eliminated, light aging is prevented, and accordingly, the composition has an ultraviolet ray preventing function and an after-sun injury repairing function.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a sunscreen and after-sun repair skin care composition. Background technique [0002] Epidermal growth factor (EGF) is a multifunctional cell growth-promoting factor. It has a wide range of cell growth-promoting activities, accelerates the growth rate of human skin cells, and promotes the growth and reproduction of new skin cells. It is a decisive factor affecting skin health. However, with the increase of age and the deterioration of the environment, the content of EGF in the human body gradually decreases, resulting in damage to skin health. Natural EGF widely exists in mammals, its content is low, extraction is difficult and costly, people usually use rhEGF instead of natural EGF. rhEGF can stimulate the proliferation of various cells derived from the ectodermal rhEGF layer and endoderm, such as cornea and epithelium. Its biological effects include: 1) Promote ...
