We’ve also gained greater understanding about the largest organ of our body due to ongoing study by scientists, medical professionals, and pharmaceutical laboratories. This knowledge has culminated in better skin care products as well as how and when to apply them so our face receives the maximum benefit. For example, every living organism operates on “circadian rhythm”, which is a built-in system regulating the processes of that organism. We have all heard about our body clock, and there are certain times of the day that our body functions better at one thing compared to another. Some examples are, generally speaking, people are most alert at 10:00 a.m., people sleep the deepest at 2:00 a.m., and melatonin is secreted between the hours of 9:00 p.m. and 9:00 a.m.
Organs in our body also have a 24-hour memory, and the skin is no exception.
The function of the skin is determined by its needs. During the day, our skin shields us from damaging effects of sun, wind, pollution, etc. It functions in a protective state, similar to armour. During the night, our skin circulates necessary nutrients and mutates, or regenerates, skin cells. While we sleep, our skin functions in repair mode.
Because of this knowledge, any skincare regime instructs us to put on creams that support its vital functions. Moisturizers in the morning are full of boosters like SPF to guard against the sun; hyaluronic acid, which holds up to 1,000 times its weight in moisture; and amino acids, which help promote good skin health. At night, moisturizers are full of retinol, Vitamin A, and niacinimide to repair any damage that the skin has received during the day.
