Did you notice the crowfeet around your eyes?

Your skin is dull and uneven.

We hear such questions a lot. These things happen when we leave our skin alone. Skin is the largest body organ and needs nurturing. Ultraviolet rays directly fall on the skin and cause aging, skin burns, fine lines, and wrinkles. The immediate fix we can use is sunscreen. It helps to maintain long-term skin health.

However, to know a little more, we should dig deeper. This article will help you to understand the basics of sunscreen and how to choose the right one.

Let’s start!

Sunscreen Vs Sunblock

Two types of UV rays are discussed: UA and UVB. The former relates to skin aging and UVB burns the skin. Sunscreen can prevent skin aging and block the sunlight. We talk about UVB rays protection more. The effects of sunscreen are not a quick fix but it heals your skin with time.

Tip of the day: Consistency is the key

What is SPF?

When you buy sunscreen, you note the numbers on it. Sun Protection Factor is a number that measures how efficiently a sunscreen will protect your skin from UV rays. SPF increases the time of protection against UV rays.

Types of SPF

SPF 15, 30, 50, and 100 offer a barrier from UVB rays at 93%, 97%, 98%, and 99% respectively. For example, if you use SPF 15 sunscreen, it will protect you for 150 minutes, and so on. As the SPF increases the time of protection would increase too.

Importance Of Sunscreen

Do you want to look like the “Evil Queen”? The snow white’s stepmom.

Of course not; she was horrible.

Then start using sunscreen. Your skin is your friend, if you behave well, it will pamper you; if you leave it alone, it will abandon you. It’s two-way traffic. To avoid fast aging, uneven tone, skin burn, and wrinkles, you should take the first step of using sunscreen.

UV Rays Love Cancer

Yes!

You heard it right; UV rays love cancer. It damages the healthy cells of our skin. The unlimited growth of unhealthy cells leads to cancer.

How to Use Sunscreen

The American Academy of Dermatology recommends that you should select a sunscreen of at least SPF 30. Look for the word water Resistant because it will stay on the sweaty skin for long. However, if you like water-based products you can go for it. Just remember, keep applying sunscreen after every 2 hours on hot summer days.

It doesn’t matter if it’s cloudy or sunny outside; days; sunscreen application is necessary. If you are a nomad; pick travel-friendly packaging. Always wear protective clothing (sun-protective goggles, hats, etc.), because sunscreen does not block all the rays even if you would choose SPF++++.

Final Thoughts

A sun protection strategy is seeking shade but nobody can live inside all the time. Outdoor is refreshing and if you are a nature lover, it will be difficult for you to stay inside. So, choose the best sunscreen for yourself.

Check the SPF, wear protective clothes and you are ready to go.
