Why is it Important to use Sunscreen on a Cloudy Day?

If you’re serious about your skin care, you’re already wearing SPF daily. It’s essential to safeguard your skin all the time, wherever you are and whatever you’re doing, because sun damage happens everywhere, literally.


Clouds filter out sunlight, but not ultraviolet emission. Studies show that clouds block as little as 20% of harmful UV rays — so even on a cloudy day you’re still getting up to 80% of the sun’s harsh effects.

It is also important to note that UV rays are independent of temperature — so you can get just as much sun damage on a cold, sunny day than you can a hot summer one.

Some conditions make you extra-vulnerable to ultraviolet rays: sand, snow, water and even pavement. These surfaces can act as mirrors, bouncing the sun back at you, putting you in risk of both direct and indirect UV radiation.

How to Choose the Right Sunblock?

Everyone, regardless of skin tone, is susceptible to skin cancer. So, no matter if the weather calls for rain or shine, wearing sunscreen products is highly recommended. But finding your daily dose of protection can be tricky, especially if you don’t know which type of products to shop for.


SPF only covers how well a product protects against UVB rays. To maintain good sun shielding habits, always look for sunscreens with broad spectrum SPF protection and make sure to reapply every two hours. That way, you get proper protection against harmful UVA/UVB rays, even when the suns not out.

Chemical Versus Physical Sunscreen: What’s the Difference?

This discussion can be broken down into absorbent versus reflector:

Chemical Sunblock: penetrate the skin and absorb the sun’s rays like a sponge

Physical Sunblock: work by forming a protective layer on the skin and deflect the sun’s rays immediately

Chemical sunscreens tend to be easier to find and offer more coverage against UVA and UVB rays. Not to mention, avoid the sticky, white ghosting effect associated with physical sunblock.

However, both types of sunscreen are effective (when applied correctly) and safe. Personal preference will play an important role in which sunscreen makeup is ultimately right for you.
