The Science of Sunscreen
One of the most important aspects of skincare is sun protection. Understanding the science behind sunscreen can help us make informed decisions about protecting our skin from the harmful effects of the sun.
How Sunscreen Works
The primary function of sunscreen is to protect the skin from the damaging effects of ultraviolet (UV) radiation. Chemical sunscreens work by absorbing the UV rays and converting them into heat, which is then released from the skin. Physical sunscreens, on the other hand, act as a barrier and reflect the UV rays away from the skin, providing a more immediate form of protection.
Types of Sunscreen: Chemical vs. Physical
Science has given us two main types of sunscreen: chemical and physical. Chemical sunscreens contain organic compounds that absorb UV radiation, while physical sunscreens contain active mineral ingredients that act as a shield against UV rays. After comparing the two types, it’s essential to choose a sunscreen that best suits your skin type and the level of sun exposure you anticipate.
