MSM is necessary for collagen production. Sagging skin and wrinkles, as well as dry, cracked skin are all developed through a loss of collagen. MSM works together with Vitamin C to build new, healthy tissues. MSM can normalize collagen formation and radically improve skin health. MSM is also highly effective in improving joint flexibility. Additionally, it helps to produce flexible skin and muscle tissue. This leads to an increase in overall flexibility due to a restoration of the “juiciness” in the tissues..
