If you look at the ingredients in your daily beauty products, most contain SPF. It is now not uncommon for moisturizers to offer at least an index of 15, while some foundations sometimes go up to 30. But what is this for, and why is it so important?
Protect yourself from UVA and UVB
If you look at the ingredients in your daily beauty products, most contain SPF. It is now not uncommon for moisturizers to offer at least an index of 15, while some foundations sometimes go up to 30. But what is this for, and why is it so important?

You need two types of rays to protect yourself from UVA and UVB. Many cosmetics don’t cover a broad spectrum, so you’re just protected against UVB. These are the rays that make your skin red, can cause sunburn and play a vital role in developing skin cancer.
But don’t think UVA rays are any less important or less dangerous since new research suggests that these rays can penetrate the skin and damage the area where many cancers develop. These rays penetrate deeper than UVB and are the leading cause of the signs of ageing and the appearance of wrinkles, following a breakdown of collagen. Therefore, it is vital to protect yourself from both UVA and UVB rays if you want to preserve a fresh and luminous complexion for years to come.
