I had a mole removed when I was pregnant but since working with Ladival, I've been keen to learn more about how the sun affects us and how important it is to be protected from infrared-A rays as well as UVA and UVBs.
Sadly UVBs by themselves don't do much for the tan and you won't be getting it for long enough to make a difference anyhow.
Protection against UVBs is measured by a lotion's SPF (sun protection factor).
UVBs are the primary cause of burning; but UVAs, in addition to burning the skin, penetrate deeper, causing genetic damage in cells and suppressing the immune system.
While choosing a sunscreen used to be a simple numbers game, as easy as counting from SPF 2 to SPF 15, recent advances in both medical detection and sun protection technology have shown that there's more to the sunscreen puzzle than just slathering on a high SPF -- you clearly need to know your UVAs and UVBs as well.
I've always been careful though, I had a mole removed when I was pregnant, but since working with Ladival I've been keen to learn more about how the sun affects us and how important it is to be protected from Infrared-A rays as well as UVA and UVBs.
The NHS recommends you use suntan lotion with an SPF (sun protection factor) - which protects against UVBs - of at least 15.
