The invention discloses a silica-gel scar removing and repairing product containing hyaluronic acid and antibacterial peptide. The silica-gel scar removing and repairing product product is prepared from, by weight, 0.5-10 parts of antibacterial peptide, 100-200 parts of polydimethylsiloxane, 100-200 parts of polydimethylsiloxane cross-linked polymers, 10-50 parts of hyaluronic acid, 4-6 parts of carbomer, 5-8 parts of triethanolamine, 100-150 parts of glycerol and 420-600 parts of purified water. A preparation method of the silica-gel scar removing and repairing product includes the steps that 1, purified water and hyaluronic acid form a hyaluronic acid solution; 2, purified water and antibacterial peptide form an antibacterial peptide solution; 3, glycerol, purified water and triethanolamine are sequentially added into carbomer to form a carbomer solution; 4, the hyaluronic acid solution and the antibacterial peptide solution are sequentially added into the carbomer solution, stirring is conducted, polydimethylsiloxane and polydimethylsiloxane cross-linked polymers are added to form a mixture, the mixture is uniformly stirred and passes through a colloid grinder, and the finished product is obtained. The silica-gel scar removing and repairing product can cure and prevent scars, has antibacterial and anti-inflammation effects, and further has the functions of conducting protection, relieving pain and itching, powerfully preserving moisture and softening and repairing the scars.
