How does sun protection factor (SPF) work?

We all know the importance of wearing clothing and supplies with a sun protection factor (SPF) ahead of summer vacation, but we're not ashamed to admit that we don't know anything about what SPF actually does, or exactly how to

do it. He works. So we did some research, and in today's blog post, we're going to share with you everything we've learned about SPF.

Before we dive in, I want to explain a little more about the difference between UVB and UVA. Both types of rays damage the skin in their own way. The easiest way to remember this is UVB = Burn. It affects the surface of the skin

and causes the burning sensation associated with excessive sun exposure. UVA = aging, which generally means that these rays penetrate deep into the skin and reach the underlying layers, causing aging of the skin, such as the

breakdown of collagen and elastin. UVA radiation is constant and requires year-round protection as it can penetrate clouds, glass and water. Therefore, many skin experts recommend wearing sunscreen every day, even on cloudy and

cloudy days, to ensure that the skin is fully protected.

What is the sun protection factor SPF?

Simply put, SPF is a product that blocks the sun's rays from damaging or burning your skin. In general, the higher the factor, the more effective it is at blocking all UV radiation. Jotting down the number on the SPF can help

you know how long you can safely stay in direct sunlight before your skin starts to burn.

To better understand how this factor protects your skin, consider how long it takes your skin to turn pink when exposed to direct sunlight. If your skin turns pink quickly, choosing the highest factor will protect you from

burning your skin over time. If you use SPF 30, you usually get about 5 hours of sun protection. It is calculated by multiplying the SPF value by the time it takes to get sunburned without protection.

To find out how long SPF works for you, here's what you need to do:

Consider your skin type and risk of sunburn

Apply properly and generously, about a tablespoon per limb, or more for larger areas

Make a note of when you apply SPF to prepare for reapplying

Reapply when standing in water or sweating

Avoid direct sunlight during the hottest part of the day

If you're vigilant in the sun, you'll find that your skin is protected and you won't have any signs of burns.

When protecting your face with SPF, it is recommended to use products specially formulated for the face to avoid the problem of clogged pores, which can sometimes lead to acne. Make sure to cleanse your skin thoroughly, followed

by an intensive skincare regimen rich in active ingredients to keep your skin healthy, radiant and spot-free.

How is the SPF of a sunscreen product determined?

SPF is a measure of the effects of UV exposure and how long it takes for the skin to experience sun damage. It was first introduced in 1974, and while the results can't be considered waterproof, it allows SPF users to keep track

of their skin's exposure to the sun, of which UVB is the main radiation that protects the skin from sunburn.

UVA rays are a little harder to avoid because the effects of these rays are invisible and you can't see the results of sun exposure as quickly. Therefore, broad-spectrum sunscreens with SPF were developed to protect the skin

from UVB and UVA radiation. You can also check the ingredient list on the package to see if something like zinc oxide or titanium dioxide is in the formula, as this will allow you to better protect your skin.

For long-term benefits, it is recommended to follow a safe sun protection regimen, which includes gradual exposure to direct sunlight, applying SPF sunscreen liberally to the skin, reapplying frequently, and staying hydrated.

When should I reapply my SPF sunscreen?

The effectiveness of the SPF decreases when exposed to direct sunlight. That's why reapplying sunscreen is an important step in your skincare routine.

If you don't want to spend too much time in the sun on your commute, adding SPF to your morning skin care will give you plenty of protection during your commute.

If you expect to be outside for an extended period of time, reapply after 2 hours to ensure you get the best sun protection. You'll find SPF in many skincare products, especially moisturizers, and using them is a great way to
start with sun protection. However, there's a common skin myth that says that if you use several different SPF products, you'll get more SPF. Unfortunately, that's not the case, and it's the most important factor over anything else you may have applied to your skin. For example, if you have a factor of 15 in your moisturizer formula before using SPF 30 daily, 30 will provide skin protection. What's the best sunscreen with SPF? Any sunscreen with SPF is better than nothing! The formulations and ingredients of everyday SPF products have come a long way since the 1970s, so I'm sure there's a product that's right for you. From built-in SPF to moisturizers, mineral solutions, sprays and lightweight day creams, no matter your skin type, you can find a product that protects your skin from UV rays and damage without causing other skin problems (such as acne) products.
