1. What is Sunscreen?
Is a product that helps to protect your skin from the harmful effects of the sun. It works by absorbing or reflecting the sun’s ultraviolet (UV) radiation, which can cause damage to your skin cells and increase your risk of skin cancer.

Contains ingredients that either absorb or reflect UV radiation. Chemical sunscreens work by absorbing the radiation, while physical sunscreens reflect it. Both types of sunscreen can be effective, but some people may prefer one over the other depending on their skin type and personal preferences.
3. Types of Sunscreen
There are two main types: chemical and physical.
Chemical Sunscreens
Contain organic compounds that absorb UV radiation and convert it into heat, which is then released from the skin. Some common ingredients in chemical sunscreens include avobenzone, octinoxate, and oxybenzone.
Physical Sunscreens
Physical sunscreens, also known as mineral, contain active ingredients like zinc oxide or titanium dioxide that sit on top of the skin and reflect UV radiation away from the skin. Are often preferred by people with sensitive skin or allergies, as they are less likely to cause irritation.
4. What is SPF?
SPF, or sun protection factor, is a measure of how well a sunscreen can protect your skin from UV radiation. The higher the SPF, the more protection provides. For example, a sunscreen with an SPF of 30 will block around 97% of UVB rays, while a sunscreen with an SPF of 50 will block around 98% of UVB rays.

Water-resistant can provide protection for up to 80 minutes in the water, while very water-resistant can provide protection for up to 120 minutes. However, it’s still important to reapply after swimming or sweating, as well as every two hours.
11. Sunscreen and Children
Children should use with an SPF of at least 30, and physical are often a good choice, as they are less likely to cause irritation. It’s also important to keep babies under six months out of direct sunlight and to use protective clothing and hats to keep them safe.

13. Sunscreen and Sensitivity
