For preventing common mistakes, keep on reading for 9 crucial facts about sunscreen.

Sunscreen Myth #1: Is sunscreen necessary all year round?

This may seem true, but hold on for just a minute. Although UV rays can be present in the winters, cloudy or rainy days, it’s not necessarily true. On some days, the radiation levels fall so low that sunscreen isn’t needed.
Unless you’ve got super sun-sensitive skin, a UV index of 0-2 means minimal danger. And for measuring your local UV level, you can check the internet or on special apps.

Sunscreen Myth #2: Does dark skin need sunscreen?

Sure, melanin aids in blocking the sun’s harmful rays. However, a study has proven that the pigment itself can react to cause skin cancer. This is why people of all shades need to use sun cream on a daily basis.

Sunscreen Myth #3: Should you wear sunscreen indoors?

UV rays can be broken down into two sub-categories; UVA and UVB. Most UVB, primarily responsible for tan and sunburn, can’t penetrate through glass. On the other hand, premature-wrinkle causing UVA still makes its way.
Even while you’re inside your car, office, or home, more than half of the rays could still be reaching you from nearby windows.

Sunscreen Myth #4: Is SPF the most important factor?

The difference between SPF ratings gets gradually lower. Switching for SPF 100 in place of SPF 30 blocks only 2% extra rays.
Here’s the breakdown if you’re interested:
SPF 15-  93%
SPF 30-  97%
SPF 50-  98%
SPF 100- 99%

Sunscreen Myth #5: Is sunscreen bad for you?

Exposing bare skin to sunlight produces vitamin D in large amounts. Sunscreen can reduce this effect, but it won’t stop it entirely. No product on the market can block 100% of incident rays.
Any sunscreen will still allow some rays to pass through. For people who suffer from a lack of vitamin D, try getting sun on body parts at non-peak hours or for a few minutes each day.

Sunscreen Myth #6: Is the shade UV-free?

There’s no doubt that many ultraviolet rays fail to reach the shade. But although lesser in quantity, reflected UV rays are still present. Sticking to shady areas should be one of your measures, not the only one.

Sunscreen Myth #7: Do you need to slather up for a short exposure?

A lot of people will tell you about the damage, even a minute of sunlight can do. Humans have only recently started using sun products and we weren’t doing so bad without it.
In abundance, there can be negative effects. But a little bit of sun here and there can boost up vitamin D and brighten up your mood. Depending on your skin type, you can remain unprotected for 5-20 minutes.

Sunscreen Myth #8: Are all sunscreens created equal?

Picking a random sunscreen from the grocery store aisle doesn’t cut it. A lot of things go into determining the effectiveness of a particular product.
Look for the type of sunscreen agent used (physical or chemical), its concentration, other ingredients, and texture. Of course, checking reviews beforehand is a recommended practice.

Sunscreen Myth #9: Can SPF be combined?

We know that the majority of individuals use much less quantity of sunscreen than is recommended. Having said that, layering two or more sun products isn’t super helpful. When you do so, your skin will only be guarded by the higher SPF.
For instance, using SPF 15 and SPF 30 together is the same as SPF 30 alone. A liberal application of sunscreen with additional SPF from makeup is optimal.

Using the same logic, it’s safe to say that sunscreen can’t be mixed with other stuff either. Gio from BeautifulWithBrains addressed the same issue in Can You Mix Sunscreen With Moisturizer?
