Our body follows the circadian rhythm, our internal biological clock, a term derived from the union of about and dies (around the day), which plays a fundamental function on the physiological activities of the body. The skin is affected by this rhythm and behaves in different ways depending on the hours of the day and night. We were inspired by this rhythm in formulating Pro Age so as to offer the skin after "age" active ingredients that during the day perform moisturizing and protective activities rich in antioxidants; at night, when skin receptivity is greater, they stimulate regenerative processes.
