March will be here by the end of the week, and the season when we are concerned about ultraviolet rays has arrived.
Titanium oxide, zinc oxide, and oxybenzone are well-known ingredients that are commonly used in cosmetics to protect against UV rays. The main focus is to protect against blue light (sunburn), but in recent years, as people use smartphones and PCs all day long, protection against blue light has become essential.
Due to these changes in our living environment, cerium oxide, which was recently introduced to us by a business partner, is attracting attention as a new ingredient in sunscreens. This was my first time hearing about it, so I looked it up online and found out that it is a type of rare earth that is used as a polishing agent for glass and jewelry, and that it has only been attracting attention as an ingredient in cosmetics in the past few years.
The best feature of cerium oxide is that it has a very wide light blocking range, and can cover not only UVB and UVA, but also blue light and infrared rays. When you use your smartphone without makeup, blue light penetrates deeper than the dermis, producing active oxygen called singlet oxygen, which accelerates skin aging.
In recent years, it seems that the health damage caused by “smartphone burn” has become serious. When you go out, you take proper sunscreen measures, but aren’t most of you unable to take care of yourself at home?
Cerium oxide overcomes the weaknesses of titanium oxide, which tends to whiten, and zinc oxide, which has weak UV protection, and also has the advantages of each, and is said to be able to eliminate active oxygen generated by blue light.
