Sunscreen Ingredients

We know that sunscreen is important but did you know there are different types of sunscreens. Do you know what is in your sunscreen? I wanted to review some of the most common sunscreen ingredients but let’s talk about why sunscreen is important.

Studies show that most people do not wear sunscreen. :Researchers from the Centers for Disease Control and Prevention (CDC) examined the results of a 2013 survey that asked participants how often they use sunscreen when outside in the sun for more than an hour. Only 14.3 percent of men and 29.9 percent of women reported that they regularly use sunscreen on both their face and other exposed skin”. Source Journal of the American Academy of Dermatologists. It is estimated that 1 in 5 Americans will develop skin cancer so it is important to wear sunscreen.

Ideal sunscreen ingredients

We would want ingredients that are safe for our skin as we need to lather up to help protect our skin.  Sunscreens can also be inhaled and ingested when  placed on the lips or sprayed. Did you know that sunscreens are readily absorbed into our skin as as many contain skin penetration enhancers? Many sunscreen chemicals can be be measured in blood, breast milk and urine samples.

What are the different types of sunscreens?

Active sunscreen ingredients come in two forms, mineral and chemical filters. The two types of sunscreens protect the skin in different ways and have different properties. Physical sunscreens such as zinc oxide reflect and scatter light. They are usually not irritating to the skin.  I use DAYLIGHT Radiance Tinted Moisturizer Broad Spectrum Sunscreen SPF 32 with LSR10®. 

Chemical screens, such as avobenzone, absorb light. The most common sunscreens on the market contain chemical filters. These products typically include a combination of two to six of the following active ingredients: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate. Mineral sunscreens use zinc oxide and/or titanium dioxide. A handful of products combine both zinc oxide with chemical filters.

According to EWG’s report on suncreen, The Food and Drug Administration has not reviewed evidence of potential hazards of sunscreen filters – instead it grandfathered in ingredients used in the late 1970s when it began to consider sunscreen safety. ” In this report EWG states that the most worrisome is oxybenzone.

Chemical sunscreen ingredients

Oxybenzone can cause allergic skin reactions (Rodriguez 2006). In laboratory studies it is a weak estrogen and has potent anti-androgenic effects (Krause 2012, Ghazipura 2017).

Avobenzone breakdown products are irritating to the skin .

Octocrylene high rates of skin allergy.

Homosalateis known to be a hormone disruptor.

Octinoxate has been found in Mother’s milk. It is known to be a hormone disrupter and a skin allergen (irritator)

In March 2015, the European Scientific Committee on Consumer Safety concluded that no concentration of methylisothiazolinone, a preservative, should  be considered safe in leave-on cosmetic products (EU SCCS 2014).

Mineral sunscreen’s

Mineral sunscreens are made with zinc oxide and titanium dioxide, usually in the form of nanoparticles. There is good evidence that little if any zinc or titanium particles penetrate the skin to reach living tissues.

Whichever form of sunscreen you decide to use ensure it is protecting againist both UVA and UVB light. Ultraviolet A rays emit the same amount of radiation from sunrise to sunset all throughout the year. whereas Ultraviolet B rays are stronger in the summer. UVB rays are strongest between 10 a.m. and 4 p.m.  UVB rays are responsible for sunburn and skin redness. They cause inflammation, surface dryness and excess dry skin buildup.

Jojoba and Cocoa Butter, which help visibly restore skin elasticity and hydration, for firmer and plumper-looking skin. Kiwi and Cranberry cold pressed seed oil contains minerals, vitamins and fatty acids skin just drinks in for ultimate nourishment and firming. Super antioxidants like Sea buckthorn, Blackberry and Cherry Seed Oil are rich in free radical scavengers such as tocopherols, tocotrienols and lutein for extra protection.

UVA rays are weaker than UVB rays but but penetrate deeper into your skin. These rays can stimulate pigment formation which results in age spots and collagen breakdown.

What do I need to know about SPF?
SPF is short for “Sun Protection Factor.” The higher the SPF number the more protection it will provide. Typically you would multiply your sunscreen’s SPF number by the amount of time it takes your skin to burn in the sun. Darker skin would take longer to turn red but darker skin is still at risk. SPF 30 x 10 minutes = 300 minutes (5 hours) without getting burned. Remember there are other factors. If you are sweating and swimming the sunscreen will come off. This is why you need to reapply sunscreen.

How frequently should you reapply sunscreen?

According to the Skincare Foundation,

“Sunscreens should be applied 30 minutes before sun exposure to allow the ingredients to fully bind to the skin. Reapplication of sunscreen is just as important as putting it on in the first place, so reapply the same amount every two hours. Sunscreens should also be reapplied immediately after swimming, toweling off, or sweating a great deal.”

You should be using 1 oz of sunscreen with every application.

Apply sunscreen everyday, even when it is cloudy out. According to the Skin Care Foundation, up to 80 percent of the sun’s UV rays can pass through clouds. This is the reason people often end up with serious sunburns on overcast days if they’ve spent time outside with no sun protection. Even in the winter months, you need to beware: Snow can reflect up to 80 percent of UV rays, increasing exposure. This is especially true if your family’s on a ski vacation– the higher your altitude, the greater your UV exposure.

UVA light from fluorescent bulbs also has potential to damage your skin so watch those computer screens. Dis you know that UVA rays can penetrate glass? Have you ver seen pictures of truck drivers who have aged more on their left side of their face compared to their right side?

Ensure you look at the expiration date.

Wear hat, sunglasses, light long sleeve tops and umbrellas to cover and protect your skin. Here are some more summer skin care tips.
