The time when sleep determines your skin

The period from 10 PM to 2 AM is called the regeneration time. During this time, the pituitary gland secretes growth hormone, and it is said that the regeneration of elastin and collagen—that is, skin regeneration—occurs most actively. For beautiful skin, it is recommended to go to bed before midnight.

However... I couldn't fall asleep until past 2 AM, so I ended up missing the skin regeneration time.
