Hello Skin Worthy fans, Nicole here. Today I am bringing you a healthy serving of cold hard facts and science. While it's not a trend, it's definitely something you should keep up with.
The skin is sensitive to ultra violet radiation.
UVA rays, also known as black light, cause tanning.
UVB rays cause damage in the form of a sunburn.
Surfaces such as snow and sand are highly reflective and can reflect UV radiation, hence the increased risk of getting a sunburn while skiing or spending the day on the beach.
What is the Ultra Violet Index?
The UV index value ranges between 0 and 11+, with zero being low UV exposure risk and eleven being extreme UV exposure risk.
A rating between 0-2 requires minimal sun protection unless you are near surfaces that reflect UV rays in which case further precautions should be taken.
A rating between 3-5 requires sun safety, especially during peak hours (11:00am-4:00pm). Sun safety includes wearing sunscreen (minimum of SPF 30 or higher is recommended) and reapplying every 2 hours, sun glasses, a hat and seeking shade.
Ratings of 6 or higher pose a large risk of UV damage, sun safety is strongly recommended. A higher number means greater risk of exposure to UV rays and a higher chance of sunburn and skin damage that could ultimately lead to skin cancer.
The UV Index is calculated based on 4 factors:
1) The thickness of the ozone layer over your city (detected using satellites)
2) The cloud cover over your city (clouds block UV radiation to varying degrees)
3) The time of year (in winter, UV radiation is lower than in the summer because of the sun's angle)
4) The elevation of your city (higher elevations get more UV radiation)
Other factors such as the time of day and the latitude (distance from equator) of your city play a role in UV rays reaching the ground.

Sunscreen is IMPORTANT
Here is why:
prevents discolouration
slows down the development of wrinkles and premature aging skin
decreases the chances of skin cancer
prevents sunburns which can cause permanent skin damage
decreases the chances of developing age spots/freckles that are caused by sun exposure
Sunscreen should be applied a minimum of 15 mins BEFORE sun exposure and reapplied every 2 hours, even more frequently if you are swimming or sweating heavily. It can be worn under makeup and some cosmetic brands actually have SPF in their products for extra protection. A physical or mineral sunscreen is best suited for people who have skin conditions such as melasma.
Skin Worthy carries a variety of mineral sunscreens from the ZO SkinHealth and Colorscience lines in the forms of primer, lotion and powder, many of which are perfect for smoothing, correcting and make for easy re-application.
