I found this pretty interesting article on MVO's blog and thought that it's a good topic to share. Enjoy!
Here are some common notions about what we need to do to keep our skin vibrant and healthy. Just answer true or false, then see if your answers agree with ours.
1) High SPF ratings are your best protection against sun damage.
The problem with a sunscreen with a high SPF rating is that, because it allows you to stay out in the sun longer without getting burned, you may feel that you have not incurred sun damage when in fact you may have exposed yourself to the more insidious damage caused by longer wave-length UVA rays. Risks from UVA over-exposure are potentially of more concern than the risks associated with simple sunburn occasioned by over-exposure to UVB rays. See #2 below for more discussion of UVA rays.
Two better ways to protect yourself are:
1) MAKE SURE YOU GET BROAD-SPECTRUM UVA/UVB PROTECTION.
2) Remember that sunburn is your natural alarm system–red skin tells you that you’ve had enough and it’s time to cover up.
