Common Sunscreen Myths You Need To Stop Believing

We all know that sunscreen is important. However, there are some common myths and misconceptions surrounding sunscreens that people should be aware of before buying their next bottle. Let us look at some of the common misconceptions about sunscreen.

1. One application lasts all day.

It is a common misconception that one application of sunscreen can last all day. In reality, sunscreen breaks down in the light and loses its effectiveness after a few hours. It is advised to re-apply sunscreen every 2-4 hours, at least.

2. Sunscreen is waterproof.

There is no such thing as a waterproof sunscreen. You should always re-apply sunscreen after water exposure. Allow the sunscreen to settle on the skin for 10 to 15 minutes before going into the water. Sunscreens that are labeled as water-resistant or sweat-resistant, or marketed as sunscreen for sports, may appear to be waterproof. Sadly, this is an overstatement of what sunscreen can do.

3. I have tanned skin. I do not need sunscreen.

People with dark skin often tend to assume that they are naturally protected from the sun. On the contrary, dark skin is just as susceptible to sun damage. Melanin, the compound that colours one’s skin, provides the equivalent of an SPF of about 1.5 to 2, which lowers the risk of skin cancer in people of colour. However, this does not eliminate the risk. Regardless of your skin colour, apply sunscreen 30 minutes before going out in the sun, and do not forget to re-apply!

4. Using sunscreen lowers Vitamin D in your body.

Vitamin D is an essential nutrient for our health, and our body makes it easily through exposure to UV rays. However, experts suggest that just 5 to 30 minutes of sun exposure per day can create the proper amount of vitamin D in the body. If you are unable to get enough sun exposure, some foods with Vitamin D are salmon, tuna, cheese, and fortified milk.

5. You do not need to wear sunscreen indoors.

Depending on your routine, you may want to wear sunscreen indoors. With many people now working from home, sunscreen may seem like an unnecessary precaution. However, most windows block out UVB rays, but UVA rays still penetrate through glass. Hence, if you often sit near a window, you may be at risk. You should use sunscreen daily and re-apply every two hours!

Understanding the truth about these myths can help people use sunscreen effectively. Remember that sunscreens are not the only way to protect yourself from the sun’s harmful rays. Other protections from sun exposure include a hat and clothing, avoiding the mid-day sun, and staying in the shade.
