During the day, the skin carries out its function as a barrier and protects the body against environmental aggressions: the sun, wind, pollution… At night it regenerates, benefiting from the rest it deserves. Sleep therefore helps to preserve the health of the skin but also slows down the internal process of ageing.

A time for hydration

You perspire more without this water evaporating as quickly as in the daytime: this contributes to the hydration of your skin.

A time for tissue regeneration

  • Your cells renew themselves far more quickly than during the day and the peak takes place at between 1am and 2am.
  • The production of collagen and elastin responsible for the skin’s firmness and suppleness increases thanks to the peaks of growth hormone secretion at the start of the night. This is known to promote healing and make the skin thicker.
  • The degradation of the proteins diminish, which helps with a better cohesion of cells.

A time for purification and protection

  • Micro-circulation is increased, especially between 11pm and 4 o’clock in the morning. The skin cells receive more oxygen and nutrients, which enables them to perform to the maximum of their potential. The complexion is one of the main beneficiaries of this great activity.
  • Melatonin, a hormone which regulates our sleep and waking cycle of which the peak of secretion is at around 2am, protects the skin cells from damage from free radicals due to their anti-oxidant action.
  • For all these reasons, it is important to ensure that one receives the right amount of sleep as often as possible: so you can give your skin the means to remain in good health. Regenerated, rested, it will resist signs of skin ageing even better.
