Divios™ Sun Care 101 Guide
Your dedicated resource for the science behind sun care and answering questions on topics to keep your skin healthy and happy.

What are UV rays? Do they help or hurt?
The two types of UV radiation that can affect the skin — UVA and UVB — penetrate the atmosphere and are present with relatively equal intensity during all daylight hours throughout the year and can penetrate clouds and glass (UVA).
The prevalence and strength of UV rays means adding sunscreen to your daily routine is more important and helpful than people often think.

UVA rays penetrate deep into the skin and are known to cause skin aging and wrinkling. More recently, studies have shown that UVA damages skin cells in the basal layer of the epidermis, where most skin cancers occur.
UVB rays mostly affect the surface of the skin but are very powerful and therefore the primary cause of sunburn, redness as well as the development of skin cancer. UVB rays are most intense during summer months, especially from 10 AM to 4 PM, but reflective winter surfaces like snow and ice can bounce back 80 perfect of the rays so they affect the skin twice.

It’s so important to note that most chemical sunscreens only protect against UVB rays, which means that while you don’t look or feel burnt (since the UVB rays are being blocked), the “longer, more penetrating UVA wavelengths may create highly reactive oxygen molecules capable of damaging skin cell membranes and the DNA inside.”
As skin cancer rates continue to rise in the U.S. — currently, one in five Americans will develop skin cancer by the age of 70 — the question of ‘what’s the best way to care for our skin’ will be asked more frequently and with greater detail.

While it’s unknown the exact cause of all skin cancers, our exposure to UV radiation (typically from the sun), is the most common underlying cause.
Additionally, the more damage we cause to the ozone layer, the more UVB rays will reach our bodies, which is why we are doing our part at Divios to be environmentally conscious with our packaging, ingredients and global footprint.
For all that’s said and marketed about the potential negative effects and risks of excessive UV Radiation (UVR), it’s critical to understand the balance the sun brings to our bodies and overall positive health benefits.

In fact, the numbers related just to U.S. skin cancer rates and their health impacts compared to those affected by Vitamin D deficiencies (leading to cardiovascular issues, diabetes, cancer, etc.) is not even close, where over an estimated 1/3 of all Americans are Vitamin D deficient. While this is due to a variety of socio-economic factors as well as nutrition, our current leisure and work lifestyles equate to more time spent inside and less outside than ever before.

Here's why the sun is so important to our health:
1. Triggers Vitamin D That Strengthens Our Bodies
This is so vital to our overall health and cannot simply be replaced or replicated by Vitamin D supplements.

As stated by the World Health Organization, “some UVR is essential to the body as it stimulates the production of Vitamin D, [which] … plays a crucial role in:
  • skeletal development
  • immune function
  • blood cell formation
2. Elevates Mood and Supports Better Sleep
We all know the feeling — you wake up to a beautiful, sunny morning and feel more inspired, motivated and happy. Well, there’s a chemical reason for that reaction. Our serotonin levels are affected by exposure to daylight, and “moderately high serotonin levels result in more positive moods and a calm yet focused mental outlook.”

Additional evidence supporting our physiological dependence on daylight emerged with the diagnosis of a condition called Seasonal Affective Disorder, or SAD. This disorder particularly affects populations living in geographic territories where sunlight hours are dramatically reduced during certain seasons, such as in Norway and Sweden. Symptoms include fatigue, depression, and social withdrawal.
3. Lowers Blood Pressure
Sure, quality time in the sun can be relaxing, but modern research indicates that “when sunlight touches our skin, a compound called nitric oxide that helps lower blood pressure, is released into our blood vessels.” The overall effect could mean that by reducing blood pressure we could cut heart attacks, strokes and other serious BP-related health issues.
4. Alleviates Certain Skin Conditions
UVR has been used to successfully treat a number of skin disorders and conditions, including:
  • rickets
  • psoriasis
  • eczema
  • jaundice

Interesting Fact: Heliotherapy has been in practice since the age of the Greeks and Ancient Egyptians. From the late nineteenth century until the early 1930s, light therapy was considered an effective and mainstream medical therapy in the UK for conditions such as varicose ulcer, 'sickly children' and a wide range of other conditions, and since then a large array of treatments using controlled light have been developed.
Sun Protection Factor (SPF)
Sunscreens protect your skin by absorbing and/or reflecting UVA and UVB rays. The Sun Protection Factor (SPF) is a relative measure of how much UVB radiation is required to sunburn protected skin. As the SPF value increases, sunburn protection increases. Remember: UVB rays are the ones that burn or redden your skin, which is why SPF relates only to UVB.

The SPF system was set up by the FDA (Food & Drug Administration) in order to regulate and provide consumers with a set of protection standards. Unfortunately, recent studies by Consumer Reports and other reveal that nearly half of sunscreens tested fail to meet their SPF claims.

Let's take a look at where SPF numbers really matter:
There is a popular misconception that SPF relates to time of solar exposure. What really matters is how the SPF scale works.

For starters, SPF 60 does not mean twice the protection of SPF 30.

Secondly, SPF 15 filters out over 90 percent of UVB rays, meaning anything below SPF 15 and a drastic reduction in protection occurs. On the flipside, anything over SPF 30 keeps out 97% of UVB rays, so don’t fall for claims of SPF 60, 70 and higher — it’s just marketing.

The American Academy of Dermatology (AAD) recommends using a sunscreen with an SPF of at least 30, which is the baseline for all of Divios’ Protect products, which have been extensively tested.

More important than SPF though is Broad Spectrum Protection and how you use sunscreen.
Why is "Broad Spectrum Protection" important?


Broad Spectrum = UVA + UVB coverage

It’s very important whichever sunscreen you choose that you select one with Broad Spectrum Protection. For decades, most sunscreens only provided coverage for UVB rays with an average of only 1/3 of sunscreens on the market in the U.S. providing broad spectrum.
All Divios Protect products provide Broad Spectrum Protection and have received a Boots Star Rating of “Ultra” — the highest grade available. The Boots Star Rating system is a proprietary in vitro method used to describe the ratio of UVA to UVB protection offered by sunscreen creams and sprays. Furthermore, all Divios Protect products have received an average critical wavelength value of 386, which is the best way to know that you are receiving adequate UVA protection.
What's the Most Effective Way to Use Sunscreen?
You should use sunscreen everyday, unless you never leave your house, which you should! Location and time outside matter though. You should be aware of your area's UV Index (via the EPA), which is an excellent resource for understanding recommended sun protection

Ultimately, sun damage adds up, and even on a cloudy day up to 80 percent of the sun’s harmful UV rays can penetrate your skin.
We recommend using Divios’ moisturizing sunscreens daily with a thin layer for your face.

If you’re spending extended time in the sun, like at the beach or playing sports or on a hike, then the best protection is to apply 1 ounce [2 tablespoons] of sunscreen to your entire body 30 minutes before going outside. Reapply every two (2) hours, or immediately after swimming or excessive sweating.

When you’re not enjoying the sun on your skin, take some time to cover up and seek shade. Your body and skin will thank you.

DO NOT USE spray or chemical sunscreens as they are less effective and harmful for you and the environment.
How Do I Treat a Sunburn?
We all know how bad a sunburn can hurt and drain our bodies — it’s why we created Divios Protect and Restore suncare products in the first place.
In the event you have a sunburn, here’s what we and dermatologists recommend:
  1. Treat as soon as possible
  2. Take a cool bath (if this is not readily available then move to #3)
  3. Use a moisturizer. Doing so will help nourish your dry and damaged skin. Divios Restore Aloe Moisturizer is scientifically designed to heal damaged skin and bolster healthy skin thanks to its all-natural, antioxidant rich ingredients, especially CBD.
  4. Do not treat sunburns with “-caine” products (such as benzocaine). These are chemicals your skin does not need.
  5. Drink water and stay hydrated.
  6. Make sure to avoid the sun (cover-up!) while your skin heals.

Remember: the skin is the body’s largest organ, so when it’s damaged, it can affect your overall health — like your immune system, mood, energy, etc. When it’s healthy, you’re happy.
