Suppose you wonder if you can use sunscreen in winter. In that case, the answer is yes. The sun and its radiation do not go away in the winter and can continue to damage the skin. So no matter if it’s winter, spring, summer, or fall, UVA and UVB rays are always there; if you don’t protect your skin properly, they can damage it.

This article will give you an overview and everything you need to know about sunscreen and its uses.

How long does the sunscreen effect last? Should I reapply during the day?

As a general rule, sunscreen is completely effective during the first two hours, and as time goes by, the protection decreases, and you have to put it on again to guarantee its effectiveness.

Ideally, it should be reapplied every two hours and more often if you are running or in a very hot place and sweat a lot. Alternatively, you should put on the protective cream before going out, cover all exposed areas of the skin thoroughly, and wait a bit until it has fully absorbed into the skin. 

Is sunscreen toxic?

No, there is no scientific evidence that sunscreen is toxic or causes skin cancer, although there are some ingredients that may be controversial. However, the American Cancer Society states that the sun’s rays increase the risk of melanoma even without severe skin burns. 

It is also true that there is a lot of controversy about the damage sunscreen ingredients can cause to reefs, marine flora, and fauna. Therefore, we recommend that, before entering the sea, river, cenote, or lake, check how the formula of your protector is composed to ensure that they do not harm the environment.

Is sunscreen enough to stay safe from the sun?

Although sunscreen is the safest and most effective way to block the sun’s damaging effects, other actions will help you double your sun protection. Take into account the following tips and, preferably, adopt them as healthy habits in your life:

  • Wear pants and light long-sleeved clothing
  • Wear wide-brimmed hats and sunglasses (preferably designed to block UV rays)
  • Sun exposure should be avoided between 10:00 a.m. and 4:00 p.m.
  • Use an umbrella when you go out
  • For extra protection, use UV protective film on your car windows.

Can I use coconut oil as an alternative to sunscreen?

No, coconut oil does not protect you from the sun, so it’s best to use a product specifically formulated to defend against its damaging effects. This does not mean that you cannot use coconut oil in products to protect you from the sun, but it should always be combined with other ingredients to provide broad spectrum UVA/UVB coverage.

Can I use sunscreen with natural ingredients?

Of course, ingredients of natural origin are gentler on the skin; besides, they are rich in antioxidant elements and represent a great option to protect the skin from premature aging.

Tips for applying sunscreen correctly

For sunscreen for the body to create a real barrier against sun damage, you must apply it the right way. Follow these tips, so you always have the best possible sun protection:

  • Apply it to your skin at least 30 minutes before going outside to absorb it fully.
  • Make sure you are using enough, the recommended amount for the body is 1 ounce (about the size of an almond), and for the face, it is two lines spread over two fingers.
  • Do not also forget to put on lips and ears.
  • Reapply every 2 hours.
  • Reapply after swimming or sweating, even if your sunscreen is waterproof.

Don’t let your skin suffer from the sun’s rays.

We are all exposed to the sun daily, and prolonged exposure can cause spots, irritation, or more serious problems such as skin cancer.

As we have already seen, UV radiation can be hazardous, and it is not something that only happens on summer days when it is hotter, but it can harm us even when we are indoors, when it is cold or when it is cloudy. Of course, always remember to check the formula first to make sure it does not contain any ingredient that may be toxic or cause any damage to the environment. 


After checking your sunscreen combination, another important thing to note is buying from the right store. Thus we recommend you buy the Tanri product for the naturally mixed sunscreen product that will help you protect your body from external harm.
