The invention belongs to the field of daily chemicals and relates to a grape seed extract and a skin care composition containing the grape seed extract. The skin care composition comprises the following components in percentage by weight (100% in total): 0.05-5% of grape seed extract, 1-12% of polyalcohol, 0.1-5% of betaine, 0.5-5% of beta-glucan, 0.05-0.6% of sodium hyaluronate, 0.2-4% of glycerol polyether, 0.5-3% of seabuckthorm seed oil, 0.1-2% of squalane, 0.5-3% of jojoba oil, 0.02-0.5% of sodium polystyrenesulfonate, 0.05-1% of thickening suspension agent, 0.2-10% of silicone oil, 2.5-4.5% of emulsifier, 0.02-0.2% of dipotassium glycyrrhizinate, 0.1-1% of D-panthenol, 0.1-2% of coenzyme Q10, 1-5% of nicotinamide and the balance being water. The skin care composition can effectivelyclear free radicals, helps skin to resist injuries of the free radicals and ultraviolet rays, resists bacteria and inflammation, is mild and anti-allergy, repairs injured cells, improves self-repair capacity of the cells, compensates water deeply, preserves moisture for a long term, promotes cell collagen synthesis, recovers cell elasticity, tightens the skin, delays senescence and resists and removes wrinkles.
