Standing upside down every day can slow down skin relaxation, which is also an important reason for collagen deficiency. Collagen is closely related to aging skin relaxation. By the time we are 40 years old, the total content of collagen in our body will be reduced by half.

Therefore, it is suggested that you should choose to repair collagen.
