The invention discloses a repairing anti-aging facial mask essence and a preparation method thereof. The facial mask essence comprises 0.1-2% of sodium hyaluronate, 0.01-1% of a golden chamomile extract, 0.1-4% of beta-glucan, 2-10% of propylene glycol, 0.5-4% of butanediol, 0.1-3% of acrylic acid / MA copolymer sodium, 2-10% of glycerinum, 0.05-0.5% of saccharomycete fermentation filtrate, 0.1-0.5%of N15 polypeptide, 0.8-1.5% of oligopeptides-1, 0.2-6% of 1,2-hexanediol, 0.2-8% of 1,3-propylene glycol, 0.3-6% of 1,6-hexanediol, 0.1-3% of caprylyl glycol, 0.01-0.15% of decoyl hydroximic acid, 0.1-5% of hexanediol and the balance of water. As natural active components of the saccharomycete fermentation filtrate and the N15 polypeptide are combined together, a skincare product with a repairing anti-aging effect is developed, the transdermal absorption ratios of the active components can be greatly increased, product effects are enriched, and meanwhile, no essence, alcohol or preservativeis used, so that the liquid temperature and low allergy of the facial mask essence are ensured, and skin irritation can be reduced. Meanwhile, the facial mask essence is simple in preparation process,gentle in reaction condition, low in raw material price and easy in raw material obtaining, and the preparation cost can be greatly reduced.
