When the summer heats up, we rush to the wardrobe to get the sunscreen we bought last year. The only problem here is that sunscreen, like the products in your wardrobe, has an expiration date. So the old bottle may not be effective, it is a mistake to believe that the expiration date printed on the products is just a suggestion from the producer.

In this article, we will get to know the sunscreen, and the most important information you should know about it, as it is important and essential at all times.

Sunscreen and Expiry Date

Expired sunscreen will not work as it should, and will increase your chances of sunburn. Sunburn not only hurts, but can also increase your risk of skin cancer.

It is worth noting that if you bring a sunscreen battle with you to the beach, and place it under the sun’s heat and ultraviolet rays, this may spoil it before its expiration date.

Sunscreen Amount

  • True or False: A small amount of sunscreen is sufficient to cover the entire body.
  • Answer: Wrong

To benefit from the maximum effectiveness of the sunscreen, you must apply an adequate amount of it. Use a small cup-sized amount, and reapply every two hours.

UV Index

  • True or False: The UV Index is a measure that helps you understand how much UV radiation your body is exposed to on a given day.
  • Answer: Right

The UV Index is really a measure that helps you understand how much of it your body is exposed to on a given day, in a specific location. The scale ranges from 1 (low) to 11 (adult). In general, an index with a low value denotes a low risk from sunlight, or ultraviolet light. The higher numbers mean the presence of radiation and greater risk.

Its principle is similar to that of a weather forecast, taking into account altitude, ozone protection, cloud coverage, and other factors in order to warn of days or areas considered particularly hazardous.

Remember: UV rays pass through clouds and windows to reach and harm your skin (causing inflammation, aging, and skin cancer), even on days that aren’t sunny, or when the radiometer’s index is low. You can easily get these numbers in detail through weather websites such as Accuweather.com or Weather.com.

Cosmetics and Sunscreen

  • True or False: If your cosmetics or moisturizers are with SPF, then you don’t need to put extra sunscreen on your face.
  • Answer: Wrong

Cosmetics or moisturizers that contain SPF give you an extra benefit, but they are definitely not enough to protect you all day long. Although these products contain a sun protection factor, you will have to use a very large amount of it, to be applied again and again, so it is illogical to use these products as a sunscreen.

Doctors suggest applying moisturizer or cosmetics with an SPF, and then apply it with sunscreen 30 minutes before you go out in the sun. Doctors also warn you not to wear cosmetics containing SPF 15 and sunscreen with SPF 15, because of course they are not equivalent to a protection factor of 30, there is no cumulative effect here.

Sunscreen and Applying Times

  • True or False: Sunscreen containing a high protection factor does not need to be reapplied several times.
  • Answer: Wrong

While sunscreen with an 50SPF or greater may offer you a little more protection than others, it is not different from other sunscreens when it comes to the number of times it must be reapplied.

Coconut Oil and Sunburns

  • True or False: Coconut oil is useful for sunburn.
  • Answer: true or false.

This question is deceptive. On the one hand, coconut oil will help you relieve sunburn after injury and damage. As all moisturizers including coconut oil, oral anti-inflammatory medications such as ibuprofen, and topical antioxidants such as vitamin C are all treatments that you can use if you got a sunburn in order to reduce the effect of inflammation.

Eyes and Sunburns

  • True or False: Eyes can get sunburned.
  • Answer: True (despite how terrible it is)

The ultraviolet rays from the sun can damage the skin of the eyelid to extend to the cornea, lenses and other areas of the eye. So you must protect your eyes with good quality sunglasses. Look for sunglasses that block 99 to 100 percent of UVA and UVB radiation, and 75 to 90 percent of visible light.

We also specialize fashion lovers with this good news: The colors and shades of the lenses do not affect their effectiveness in blocking ultraviolet rays. Just make sure you wear the right size sunglasses for you, so that it is fixed and attached to the face and does not move from its position during movement. Knowing that glasses with wide lenses and the shape around the eyes is enough to protect your eyes from all angles.

Sun and Skin Cancer

  • True or False: True or False: Sun exposure is the only cause of skin cancer.
  • Answer: Wrong
