Taking collagen regularly can help solve a variety of problems. Speaking about the properties of collagen, first of all, we remember about slowing down aging. From the school chemistry course, we remember that a protein is a long filamentous molecule with a complex structure. It is these threads that support our skin in an elastic, tightened state, give clarity to the oval of the face and fight against sagging skin. Collagen supplements help keep these filaments firm and tight as they become weaker and thinner.
