What does the skin's hydrolipidic film protect against?

Absorption of UV rays
Evaporation of water and external environmental damage
Production of melanin
Synthesis of Vitamin D

The correct answer is: Absorption of UV rays

The skin's hydrolipidic film acts as a protective barrier that helps prevent the absorption of harmful external substances, including UV rays. This film is made up of a combination of sebum and sweat, which helps to maintain the skin's natural pH balance and protect against moisture loss, pathogens, and environmental damage. Therefore, Option A is correct because the hydrolipidic film plays a crucial role in shielding the skin from the damaging effects of UV rays.
