Which sunscreen is right for me?
The sunscreen market can be confusing and overwhelming. Sometimes it’s hard to know where to start, with different formulations, application methods and prices. Luckily, dermatologists Dr Adil Sheraz and Dr Bindi Gaglani have put together this handy guide.
It's important to note that the effectiveness and suitability of sunscreen can vary depending on individual skin types and needs. It's recommended to choose a broad-spectrum sunscreen with an SPF (Sun Protection Factor) of 30 or higher, and to reapply it every two hours or as directed on the product label.

What’s the difference between chemical & physical or mineral sunscreens?
Chemical sunscreens work by absorbing the sun's UV rays and converting them into heat. The active ingredients in chemical sunscreens include compounds like avobenzone, oxybenzone, octinoxate, and octisalate. Chemical sunscreens are typically easy to apply and blend into the skin. Traditionally, it has been advised that these should be applied 30 mins or so before going into the sun, although some newer formulations tend to have an immediate effect.
There have also been some claims with regards to coral reef damage from chemical sunscreen ingredients such as oxybenzone, however this is not entirely clear. The levels found in the ocean would be miniscule, and other factors such as climate change may have more of a role. Some places such as Hawaii have banned sunscreen containing these ingredients, to protect their coral reefs, this decision is however controversial, and more research is needed.
What are the different types and ways to apply sunscreens?
There are different formulations and modes of sunscreen application to ensure proper coverage and maximum effectiveness.
Spray sunscreens can either be chemical or physical and come in aerosol cans designed to be sprayed directly onto the skin. While they are convenient and easy to apply (especially in hard-to-reach areas), it's important to ensure even coverage. When using, position the can 4-6 inches away from your skin and spray evenly, making sure to cover all exposed areas. Remember to rub in gently afterward. It may be best to avoid spraying on the face to prevent inhalation or getting into the eyes, particularly when it comes to children.
Regardless of the mode of application or formula, it is essential to ensure that you apply sunscreen generously and evenly to all exposed areas of the skin. Don't forget areas like the ears, back of the neck, and tops of the feet. Reapply sunscreen every two hours or as directed on the product label, especially after swimming, sweating, or towel-drying. The best sunscreen is the one you will use!
