Which sunscreen is necessary before going out in the sun?

In the summer, we face intense sunlight as soon as we step outside. The sun's rays contain ultraviolet rays (UV rays). Prolonged exposure to the sun gradually damages the skin. In such a situation, SPF (Sun Protection Factor) sunscreen can protect the skin.

So, in this article, we'll talk about SPF. We'll also learn:

Why is it important to apply SPF sunscreen in the summer?

How does it protect the skin?

What harm can be caused to the skin if sunscreen is not applied?

What is SPF? What is its use?

SPF (Sun Protection Factor) is a rating that indicates how much protection a sunscreen provides against UVB (ultraviolet B) rays. The higher the SPF, the longer the skin remains protected from UV rays. This helps protect the skin from damage, tanning, and premature aging.

What is SPF sunscreen?

SPF sunscreen is a type of sunscreen (like a body lotion applied during the day) that is SPF-rated. This means it has the ability to protect against the sun's UVB rays. It protects the skin from the sun's harmful rays by forming a layer on the skin and reducing the effects of UV rays.

Sunscreen creams are labeled SPF 15, 30, or 50. What does this mean, and what's the difference between these creams?

The SPF on sunscreen indicates the level of protection it provides against UVB rays, and this protection increases gradually with each SPF level. For example:

SPF 15 = 93% UVB Ray Blocking

SPF 30 = 97% UVB Ray Blocking

SPF 50 = 98% UVB Ray Blocking

Is a higher SPF always better?

No, a higher SPF isn't always better, as the difference in sun protection between SPF 30 and SPF 50 is very small. For example, SPF 30 protects against approximately 97% of UVB rays, while SPF 50 protects against approximately 98% of UVB rays, meaning the difference is minimal. If you only need to go outside for a short period of time each day, applying SPF 30 sunscreen is sufficient.

How does SPF protect our skin from UV rays?

SPF acts as a protective shield, forming a layer on the skin to reduce the effects of harmful UV rays. Now, read carefully:

UVB/UVA rays are emitted from the sun.

UVB rays cause sunburn and skin damage.

UVA rays cause skin aging and tanning.

SPF acts as a skin shield.

Creates a protective layer on the skin.

Reflects back UV rays.

Also blocks UVB rays.

What is the difference between UVA and UVB rays?

Both UVA and UVB are harmful rays from the sun, but their effects differ.

UVA

UVA rays cause long-term damage to the skin. They penetrate deeper into the skin, causing wrinkles, pigmentation, and premature aging.

UVB

UVB rays cause short-term damage to the skin. They affect the upper layers of the skin, causing sunburn, redness, and tanning. Therefore, it is important to choose a broad-spectrum sunscreen.

What is a broad spectrum sunscreen?

Let's understand this with pointers:

● A sunscreen that protects the skin from both types of rays (UVA and UVB) is called a broad spectrum sunscreen.

● It not only protects against sunburn but also provides protection against damage like tanning, pigmentation, and premature aging.

● Using such a sunscreen daily, provides complete protection to the skin.

Which people should definitely use SPF sunscreen?

Everyone should use SPF sunscreen, but it's especially important for some people:

Those who are exposed to the sun every day.

Those who travel a lot.

Those with sensitive skin.

Those who tan easily.

Those with pigmentation or acne.

Young children.
