The Ultimate Guide to Sunblock: Answering All Your Curiosities

Sunblock is a must-have in the world of skincare. It protects you from the sun's harmful UV rays. It's important to know how to protect your skin as we enjoy the warmth and brightness of sunny days. This guide will answer all your questions about sunblock and provide you with the information to keep yourself safe in the sun.

What is Sunblock Sunblock is a sunscreen.

Sunblock is also known as sunscreen and it's a topical skin protection product that shields your skin from harmful UV radiation. Sunblock creates a barrier that helps to prevent sunburn and premature aging. It also lowers your risk of skin cancer.

Sunblocks are available in different types.

Sunblock comes in two main types:

Physical Sunblock: Uses active minerals such as titanium dioxide or zinc oxide. These minerals are deposited on the surface of your skin and reflect UV radiation.
Chemical SPF: Made of organic compounds which absorb UV rays and convert them into heat. This heat is then released by the skin.

Understanding SPF

SPF is the Sun Protection Factor. It indicates the level of protection that a sunblock provides against UVB rays - the main cause of sunburn. An SPF of 30 will allow you to spend 30 times more time in the sun without burning than if your skin was not protected.

Application Frequency

Apply sunblock 15-20 minutes before exposure to the sun and reapply it every 2 hours. Even if the sunblock is water resistant, it's important to reapply every two hours after swimming or exercising.

Sunblock for Cloudy Days

Even on cloudy day, sunblock is still necessary! Sunblock is essential for protecting your skin against UV rays that can penetrate clouds.

Sunblock for Children

Sunblocks are safe for children. However, it is best to use products designed specifically for babies or kids. These products often contain gentler ingredients. Avoid using sunscreen on infants younger than six months. Instead, opt for protective clothing and shade.

Sunblock that has expired can be used

Sunblock that has expired can lose its effectiveness over time. Check the expiration date on your sunblock and replace it if necessary.

How much sunblock should I use?

Use approximately one ounce of sunscreen (the equivalent to a shotglass) on your entire body. Do not forget to cover areas that are often overlooked, such as the ears, the back of the neck and the tops of your feet.
