As can be seen from tables 1 and 2 and the observation results of a transmission electron microscope, the sodium hyaluronate of the products obtained in examples 1 to 4 has a significantly higher permeation rate than the products obtained in examples, and when the weight ratio of the dimethylsilylated silica to the sodium hyaluronate is 10-15: 1, the sodium hyaluronate spheres of the products of examples 1 to 3 can permeate the surface layer of the skin more rapidly, absorb water in the dermis and expand to 20-30 times of the original volume, so that the skin bulges from inside to outside, and the effect of rapidly removing wrinkles is achieved, and the sodium hyaluronate can be gradually absorbed by muscle base cells, so that the muscle base is more elastic. When the weight ratio of silica dimethyl silylate to sodium hyaluronate is 5:1, sodium hyaluronate spheres are small and can be rapidly absorbed by the skin surface layer, but the increase of the absorption swelling volume is small, the effect of removing wrinkles and smoothing wrinkles is not obvious, and the capability of preventing water evaporation is poor. When the weight ratio of silica dimethyl silylate to sodium hyaluronate is 20:1, the sodium hyaluronate spheres themselves are large in volume and are not easy to rapidly penetrate the surface layer of the skin.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
