Should I wear sunscreen at night?

We all know that it is necessary to wear sunscreen to prevent sunburn, premature aging and cancer from the time the sun comes up to when it goes down as its harmful rays are everywhere and can penetrate through clouds and windows.

So, even if it is rainy, cloudy or snowy, you should still slather on your sunscreen. There are a few people though that wear sunscreen at night too. But do we really need it at night? No, we don’t. There is a reason why it is called sunscreen after all. What’s the point of wear sun-screen if there is no sun?

Sunscreen to protect against UV rays from lightning and computer screens?

While it is true that our computer screens, televisions and lighting can emit some UV rays (and hence why some people wear sunscreen at night too), I don’t think this is a real concern. In fact, the radiation they emit is very minimal compared to the radiation that comes from the sun. It is good to protecting our skin, but we don’t have to become paranoid about it. If you’re really worried, turn the lights off or don’t spend too much time in front of your computer, but don’t waste your sunscreen when it isn’t needed.

Is wearing sunscreen at night bad for skin?

On the contrary, there are also those that say that wearing sunscreen at night is bad for skin and will cause breakouts. But that’s not always true. Yes, there are some sunscreen ingredients (like Titanium Dioxide for example) that can clog pores and cause pimples, but that depends on how sensitive your skin is and how high their concentration is in the product.

But if the sunscreen you use during the day works fine and doesn’t cause your skin to break out, then it won’t cause breakouts at night either and you can use it safely. Your skin won’t suffer for it. Your wallet will. Using sunscreen, or moisturizer with sunscreen (which are usually a bit pricier than those without SPF), when they aren’t necessary means that they will run out sooner and you’ll have to buy them more often.

Overall, even if wearing sunscreen at night is not bad for your skin, I think it is an unnecessary waste of product and money.

      Tammy, if you have a LED monitor you should be fine, they shouldn’t emit any. But yeah, some computer screens can emit UV light but I wouldn’t worry too much about it. 😉

      Ria, I agree! We should give skin a rest at night so that it can regenerate and repair itself, wearing sunblock is useless.

      Makeup Morsels, good for you! Sunscreen should be worn every day regardless of the weather but at night it’s taking things too far imo.

    I laughed when I saw the title of this post because I used to be paranoid I was ruining my skin by not wearing sunscreen at night. I also read that household lights emit UV rays, and I never knew how much, so a long time ago I did wear sunscreen at night. Now I don’t. However when I don’t leave the house in the day time, I get paranoid when I’m not wearing sunscreen because UVA rays can come through the windows and cause wrinkles! My boyfriend loves opening all of the blinds, and sometimes I put on sunscreen, just to be safe!

      Jeni, I wear sunscreen at home during the day too. Everyone thinks I’m crazy for doing it but you’re right. UVA rays can penetrate through windows and cause premature aging and so I’d rather be safe than sorry. After all, putting on some sunscreen doesn’t hurt at all. At home, I use my sunscreen in the summer but in winter when the weather’s bad I use a moisturizer with SPF as that should be enough.
