How Does Sunscreen Protect Your Skin?

How Does Sunscreen Protect Your Skin?

The smell of Sunscreen will instantly send you into summertime nostalgia. With summer approaching, that means beach and pool days await. However, if you aren't protecting your skin adequately, fun in the sun can come with consequences. Nourishing Biologicals doesn't want to see your precious skin sunburned or sun-damaged.

When it comes to protecting your skin, Sunscreen is the most convenient and effective protection method. We want to inform you how Sunscreen protects your skin and other ways to keep your skin safe from UV rays and overall healthy.

How Does Sunscreen Work?

If you sat and pondered on Sunscreen and how it works, it might merit some confusion (rightfully so). We're going to break it down and answer all your sunscreen-related questions.

Sunscreen protects your skin with a few ingredients that block the sun and prevent UVA and UVB rays from penetrating your skin. Common active ingredients in sunscreen are oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate.

There are two types of Sunscreen —- physical blockers and chemical blockers. Each one has different sunscreen ingredients.

Physical blockers: Physical blockers are sunscreens made up of minerals (titanium dioxide or zinc oxide) grounded up into fine particles. These physical blockers sit on the skin and ward off unwanted UV rays.

Chemical blockers: chemical sunscreens contain carbon. This sunscreen offers a thin layer of protection for the skin. This layer absorbs the UV rays before it penetrates the skin.

Which Sunscreen Is Better For Your Skin?

Neither sunscreen product is better than the other; in fact, most store-bought sunscreens are a combination of both. When it comes to sunscreen, the most important thing is that you apply it every day, especially if you plan to be in the sun a lot.

Everyone's skin is different, and certain creams and lotions can cause irritation — the same goes for sunscreens. As long as the sunscreen you're using doesn't irritate or bother your skin, it's fine to use! The most important thing is that your sunscreen prevents skin damage.

What Are the Side Effects When You Don’t Apply Sunscreen

The sun's ultraviolet rays are powerful and can cause severe damage to your skin. Here are some signs of sun damage and ways to avoid it altogether.

Premature Fine Lines and Aging

Yes, wrinkles are inevitable and nothing to be ashamed of. However, there is nothing wrong with wanting to keep your skin's appearance young and rejuvenated.

Premature wrinkling occurs with UVA, and UVB light penetrates deep into skin cells, causing sunburn and sun damage. These UV lights damage the elastic fibers that keep the skin firm, which can cause wrinkles to form.

Of course, whether they be premature or developed with age, Nourishing Biologicals is here to help. Our Miracular Face Serum is a highly hydrating and plumping serum that visibly reduces the look of fine lines, wrinkles, and dullness for healthier-looking skin.


Whether it is due to natural sun exposure or UV radiation from a tanning bed, sunburn is one of the most common forms of sun damage. It's no fun and can often mess up your efforts to get that perfectly sun-kissed skin. Depending on your melanin levels, your burn will either tan or peel away. In the worst cases of sunburn, it will blister and scab.

While aloe vera is a great way to soothe your sun-damaged skin, it's best when you're able to avoid sunburn completely.

Pigmentation Issues

Sun damage can cause pigmentation issues. Pigmentation spots occur when your skin tries to protect itself from the sun's UVA rays and UVB rays by increasing its production of brown pigmentation (melanin). This is how your skin is able to tan.

Pigmentation spots occur when your body sends melanin to only certain parts of the body, resulting in dark brown spots.

What Are the Best Ways To Avoid Sun Damage

If you're usually in the sun quite a bit, avoiding sun damage might pose more of a challenge. However, all it takes is some consistency and courtesy to your body.

Aside from applying broad-spectrum protection every day, there are other ways to protect your skin.

Always Wear Sunscreen

Of course, this has to be the first on the list — it is the most effective.

Your morning sunscreen application should be as high on your priorities list as your cup of joe. The best way to never skimp on sunscreen is by having a solid skincare routine (both morning and night).

Your sunscreen should be at least SPF 30 or higher. If you have more sensitive skin, opt for a higher SPF to boost your sun protection factor.

Some moisturizers and lotions have some SPF but usually aren’t higher than SPF 15. SPF 15 can be helpful, but it doesn’t offer enough protection to last you all day.

If you have a pool or beach day on your agenda, Nourishing Biologicals suggests opting for a water-resistant sunscreen. This prevents your sunscreen from running off prematurely.

We understand that everyone has their special order in which they apply their products, but if you haven't found a routine that you love, here's our go-to skincare routine order.

Avoid the Sun in the Middle of the Day

If your skin is super sensitive, we suggest steering clear of the sun for a period of time between 10 am to 3 pm. Of course, we realize this won't always be feasible, but we say try it when you can.

The sun is at its harshest and tends to wreak the most havoc during these times. If the sunshine isn't avoidable, we suggest wearing protective clothing, reapplying your sunscreen every few hours, and seeking shade when possible.

Wear Protective Clothing

Wearing protective clothing is a great way to ward off the sun's harmful rays, even when it's scorching hot.

We say opt for dry-fit, breathable materials. If you bundle up, your body may overheat (which is no good). You want to have some protection for your skin while still keeping your body cool.

Seek Shade Often

While the sun can be damaging and cause early skin aging, that's not to say it's not good for you —- everything in moderation.

We don't want you to feel like your summer must be spent inside or undercover. While prolonged sun exposure can damage the skin, protected time in the sunshine is good for you — encouraged, even!

Being in the sunlight can boost a hormone called serotonin. Serotonin can give you more energy, calm your mood, and keep you focused. Like most things, sunlight can be enjoyed, just in moderation and with the right level of protection.

Other Ways To Keep Skin Healthy

We've told you all there is to know about sun damage and how to prevent it. Now, let's talk about other ways to keep your skin healthy.

Yes, healthy skin starts with protecting it from the sun, but that's not to say there aren't other ways you can keep your skin looking young and luminous.

Use High-Quality Products

When it comes to skincare, this is an area where splurging is (almost) a necessity. Using high-quality, well-formulated products known for their clean ingredients is a great way to show your skin some love.

Here at Nourishing Biologicals, we take pride in our products. We are a bio-science company dedicated to creating clean, clinically proven, and sustainable products that treat the cause, not just the symptoms, to advance health and wellness for all.

We use groundbreaking scientific research to add a new dimension to our skincare products.

Have a Daily Skincare Routine

Having a daily skincare routine is beneficial in many ways. This will ensure you never skip the crucial step of applying sunscreen. Your skincare routine doesn't have to be complicated —- as long as you have your Nourishing Biologicals Miracular Hydrating Cleanser, Miracular Skin Essence, and our Miracular Facial Serum to lock in all those key ingredients, you're set.

Sunburn, Be Gone

At Nourishing Biologicals, we believe that sunscreen is one of the more effective ways to protect your skin from the sun’s harsh UV rays. As long as you're applying your sunscreen every morning and reapplying it every few hours, your skin should have plenty of UVA and UVB protection.
