Hello,
I would like to ask about infrared rays. Do I need to consider it in my sunscreen? I found two brands only that have that protection, Lancaster and Ultrasun. Please, can you tell me how these rays work?
Many thanks. I love all this website. It’s very informative.
Thank you so much for your kind feedback!
The short answer is No, there is no practical benefit in looking for protection from infrared rays in a sunscreen. The first reason is that sunscreens do not block infrared rays. They can include antioxidants that help neutralise free radicals protecting the skin this way, but it is not what consumers usually understand under "protects against infrared light". If you want to do something for your skin to help it fight potential damage from infrared light, use topical antioxidants during the day (for example, a product with ascorbic acid). Eating plenty of fruits and vegetables will also help.
We do not see infrared light, but we can feel it - it heats up our skin. Infrared light can be beneficial for skin (that's why there are devices that treat skin with infrared light to help stimulate collagen production). At the same time, infrared light can also be harmful to skin - research shows that it can lead to hyperpigmentation, increase inflammation and generate free radicals. Scientists still do not know enough to tell us with certainty when infrared light is good and when it is bad for our skin. Most likely, a little bit of infrared light of a certain frequency can be helpful to our skin, but too much of it is damaging. If your skin is prone to hyperpigmentation or melasma, it is best to avoid heat and infrared radiation (for example, by seeking shade, avoiding saunas, being careful with hot drinks ☕️ near your face).
