• Sunscreen – the yearlong companion

      0 comments

    Now that cold weather and rainy days have taken summer’s spot, the sun danger isn’t totally gone. Even during winter days, the UV rays can be powerful and the UV index quite high. This means you’ll need extra sun protection all the time. It’s not something seasonal, ultra-violets happen every day even through the clouds.

    TIP: Your local weather forecast usually includes the UV index for the day. Wearing sunscreen is a must for anybody if the index is above 2.

    Sunscreens are ingredients designed to protect skin from the ultraviolet radiations. Among other ingredients meant to facilitate absorption or reflection of the UVs, sunscreens contain a main filter ingredient -usually zinc oxide or titanium dioxide- andsunscreen advice, once applied on the skin, it blocks the UV rays from penetrating the skin layer

    So don’t throw away your sunscreen lotion after summer. Use is throughout the year and save your skin! Sunscreen has multiple benefits:
    • It blocks harmful UVs , minimizes their effects on the DNA, and protects against skin cancer
    • It shields and preserves a youthful complexion
    • It protects against sunburns and other types of tissue damage that can leave scars and spots

    Do you know how to make the best of it? Here are the DO’s of sunscreen:

    DO wear sunscreen all the time if you have sensitive or fair skin; apply generous amounts of sunscreen on your skin
    DO use broad-spectrum UVA/UVB sun-block to protect against both types of UV rays
    DO put the sunscreen on 15 minutes before sun exposure and reapply another layer after 15-30 minutes of sun exposure.
    DO use protective clothing and hats even when you’re wearing sunscreen on high UV index days
    DO use sunglasses to protect your eyes from UVs
    DO reapply sunscreen every two-three hours, no sunscreen lasts all day on your skin. Even the water resistant formulas won’t last all day after bathing or swimming.
    DO learn more about the effects of sun radiation: for example, you know there are two types of harmful UV rays but do you know they’re not the same? UVBs cause sunburns and UVAs damage the skin and have no immediate visible effects, but harm in the long run, i.e. skin aging.

    SPF100?
    The latest news draw our attention to the new release on the market of a sunblock lotion with SPF 100. This made scientists and doctors wonder if this is really needed or if this simply a numbers game. Basically, the difference in the protection level would not be huge, they say: SPF 50 would protect us from 98% of the UVs, while SPF 100 would offer 99% protection- which is not much more. Therefore the amount of protection offered by SPF 100 is not double in intensity, but rather in permitted exposure time.

    Did you know? The intensity of UV radiation reaching the earth varies depending on how high the angle of the sun is in the sky. The sun reaches its highest angle at solar noon, which not always corresponds to 12:00 on clocks.
