Question

How often does human skin regenerate itself?

Answer 1

Hint: In our human body, our skin is the most part and we cared about it the most among all the parts of our body and skin is a natural protector to us as it protects us from UV radiation and also from diseases, pathogens, and infections and it changes with the change in our age.

Complete answer:
Human skin is the most sensitive one and it consists of three layers are the epidermis, the dermis, and the subcutaneous tissues and for these all the three layers' regeneration rate is different.

Regeneration rate for the epidermis layer that is the uppermost layer in the skin and for renewal it undergoes constant changes as to be replaced by the new ones all the cells go to be a superficial cell after every 28 days.

As for infants, this turnover is very fast, and with the increment, in the age of a human body, this turnover rate gets slowed down.

As the skin is the outermost layer of the body and gets more damages due to any mishappenings like accidents so the healing process is also fast in the infants and it slows down with increasing age of the lifetime.

In the healing process, skin sheds off, and stem cells inside the skin like epidermal cells than multiplication or differentiate to make the skin again.

Hence, the correct answer is option ()

Note: The second and third layers of the skin that are dermis and subcutaneous tissue helps in maintaining the body temperature and protect us from harmful micro life.
