Last week we started a discussion on sunburns and sunscreens. Kallgren Dermatology in Boulder carries several product lines we recommend for your daily skin care. One of these product lines is EltaMd sunscreens. They are broad spectrum sunscreens, meaning hte protect against both UVA and UVB rays and thus offer your skin the best protection.
UVB rays are to a great extent absorbed by the ozone layer at yet, they are the ones we see the evidence of. UVB rays are the rays that activate melanin in our skin causing a tan, or sunburn depending on your skin type. UVB causes some types of skin cancer as well as damage to DNA.
SPF stands for Sun Protection Factor. The number mean the length of time you can stay in the sun without getting burned. As we can see from the explanation above, it is UVB rays that cause sunburn and so SPF is really only telling you what about of UVB rays are being blocked, and not telling you about the UVA rays, which are quite dangerous.
Your best bet is to use a sunscreen with UVA/UVB protection, otherwise known as broad spectrum protection.
EltaMD Sunscreens offer a range of options for sun protection. It does not clog pores and is perfect for sensitive skin, EltaMD has the EltaMD UV Clear Broad-spectrum SPF 46. It comes in tinted and untinted. It offers physical barrier protection that goes on silky smooth and can be worn with or without make up.
