Aging is a natural process resulting from the changes that occur in the body due to the gradual decrease in the activity of the cells within it. In addition to this, regenerative processes slow down, and resistance to environmental factors becomes weaker and weaker. The changes that occur in the human body as a result of this process can be seen on the outside and felt on the inside. One of the first symptoms is the deterioration of skin and hair. However, it is possible to slow down this process and mitigate its consequences, such as by supplementing with GHK-cu peptide.
