If you want good skin, go to sleep at 9.

It is said that growth hormone is secreted vigorously between 10 PM and 2 AM.

If you sleep at this time, damaged skin tissue recovers, allowing you to maintain healthy skin.

However, growth hormone is not secreted simultaneously with sleep.

It is said to be secreted during the deep sleep stage.

They say that you enter the deep sleep stage about an hour after falling asleep.

If you want to see skin regeneration effects starting at 10 PM, it is best to go to bed at 9 PM.

Sufficient sleep makes for good skin. Everyone, remember 9 o'clock.
