Abstract

The invention discloses essence containing ultra-small molecular sodium hyaluronate and a preparation method thereof, and belongs to the technical field of cosmetics. The essence disclosed by the invention comprises the following components of, in percentage by weight, 0.01%-3% of the weight percentage of the ultra-small molecular sodium hyaluronate with the molecular weight of 1-3kDa, 0.01%-2% ofthe weight percentage of the hydrolyzed sodium hyaluronate with the molecular weight of 10-50kDa, 0.01%-1% of the weight percentage of the macromolecular sodium hyaluronate with the molecular weightof more than or equal to 1000kDa, 0.2%-16% of the weight percentage of the humectant, 0.2%-7% of the weight percentage of the bacteriostatic agent, and the balance water. The essence disclosed by theinvention has excellent anti-wrinkle and anti-aging effects on the basis of long-acting water replenishing and moisturizing, is not sticky in skin feeling after being smeared, is better absorbed, andhas the effects of repairing cuticle, improving skin texture and regulating skin cell activity.

Description

technical field [0001] The invention relates to an essence containing ultra-small molecule sodium hyaluronate and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] As people's pursuit of beauty is increasing day by day, people's skin care requirements are getting higher and higher, and naturalization, safety and efficacy have become more and more important development directions. Essence is an important product in skin care products. The high-efficiency essence ingredients have various functions such as moisturizing, repairing, whitening, freckle and anti-wrinkle. [0003] Hyaluronic acid has a super water-absorbing ability and is widely used in cosmetic formulations. However, in order to pursue short-term functional effects, hyaluronic acid essences in the world will add various complex chemical components and preservatives. Long-term use , will erode human skin, cause allergies, redness, and other adverse reactions;...
