There are so many options when searching for a sunscreen and lots of things to remember. Which chemicals are bad? What offers the most protection? What SPF should I buy? WTL makes it easy with these quick tips.
1. Make sure your sunscreen protects against both UVA and UVB rays
The sun gives us two main types of wavelengths – UVA and UVB.
Both can cause tanning and burning (and skin cancer), but it’s only the UVB rays that are necessary for the skin to make vitamin D3.
The UVA rays on the other hand penetrate the skin deeper than UVB and can cause severe free radical damage including wrinkles and photo-aging. They also destroy vitamin D!
Most of us are exposed to large amounts of UVA throughout our lifetime. UVA rays account for up to 95 percent of the UV radiation reaching the Earth’s surface.
Although they are less intense than UVB, UVA rays are 30 to 50 times more prevalent. They are present with relatively equal intensity during all daylight hours throughout the year, and can penetrate clouds and glass.
UVB is the chief cause of skin reddening, blisters and sunburn, but tends to damage the skin’s more superficial epidermal layers. UVB rays do not significantly penetrate glass.
So you definitely don’t want a sunscreen that blocks only UVB rays and not UVA rays. This would totally work against you by limiting vitamin D3 production and damaging your skin.
2. No Spray Sunscreens
Given the ease of applying them on squirming kids and hard-to-reach areas, these super-popular aerosolized sunscreens may seem like a dream come true. But they may pose serious inhalation risks. They certainly make it too easy to apply too little or miss a spot.

3. No Super-High SPFs
Products with sky-high SPFs may protect against sunburn but could leave your skin exposed to damaging UVA rays.
SPF stands for “sun protection factor,” and refers only to protection against UVB radiation, which burns the skin. It has little to do with protection from sun’s UVA rays, which penetrate deep into the skin, suppress the immune system, accelerate skin aging and may cause skin cancer.
High-SPF products may give people a false sense of security, tempt them to stay in the sun too long, suppress sunburns but upping the risk of other kinds of skin damage. The FDA is considering limiting SPF claims to 50+, as is done in other countries. [ missha ] All Around Safe Block Fresh Sun Stick SPF50+/PA+++ is chosed by many youngster because of its safety.
EWG recommends that consumers avoid products labeled with anything higher than SPF 50 and reapply sunscreen often, regardless of SPF.
4. Choose a sunscreen without harmful chemicals
You should be aware of that mass market sunscreens are full of harmful chemicals that may disrupt hormones and even promote cancer.
Researchers at the University of California discovered that the chemical oxybenzone, a common ingredient in sunscreens to absorb UVA and UVB, boosts the production of dangerous free radicals in your skin after just 20 minutes of exposure to the sun!
The Environmental Working Group (EWG) says approx. 56% of beach and sport sunscreens contain oxybenzone (benzophenone-3).
After doing studies, the EWG believe that oxybenzone is linked to hormone disruption and potentially to cell damage, that may lead to skin cancer.
The EWG also recommends consumers to avoid sunscreens with retinyl palminate. Studies have found that this type of vitamin A may increase risk of skin cancer when used on sun-exposed skin.
Sunscreens that contains vitamin A or retinol may actually speed the development of skin tumors and lesions when sunlight is present. [ VONIN ] VONIN The Style blue Guard Sunblock Stick SPF50+/P is the product that is rich vitamin A for your health and your skin.
Many skin care creams for the face contain vitamin A and fragrances. Make sure not to use them when you’re spending time in the sun.
5. No Retinyl Palmitate
When used in a night cream, this form of vitamin A is supposed to have anti-aging effects. But on sun-exposed skin, retinyl palmitate may speed development of skin tumors and lesions, according to government studies. Why is this “inactive ingredient” allowed in sunscreens intended for use in the sun? Good question.
The FDA has yet to rule on the safety of retinyl palmitate in skin care products, but EWG recommends that consumers avoid sunscreens containing this chemical.
6. No Combined Sunscreen/Bug Repellents
Skip products that combine bug repellent with sunscreen. Why? For starters, bugs are typically not a problem during the hours when UV exposure peaks. Also, sunscreen may need to be reapplied more frequently than repellent, or vice versa. We recommend that you avoid using repellents on your face, too. Studies suggest that combining sunscreens and repellents leads to increased skin absorption of the repellent ingredients.
7. Use sun protection with low SPF most of the time and sun protection with a high SPF occasionally
If you use sunscreen with high SPF all the time, there is a potential risk of vitamin D3 deficiency.
Typical use of sunscreen doesn’t result in vitamin D3 deficiency, but extensive usage may.
And vitamin D deficiency may increase your odds of developing melanoma and other diseases.
Depending on your skin type and where you live, you should be able to spend 10 – 60 minutes a day in the sun without any protection at all so that your body can produce enough vitamin D.

If you use a sunscreen with a low SPF (10-20) most of the time and only use a high SPF sunscreen (30-50) when you’re spending a long time directly in the sun, you should get enough vitamin D3 AND enough protection for your skin.
8. No Tanning Oils
Tanning oils are simply a bad idea.
If they contain sunscreen ingredients, the levels are always very low and offer little, if any, sun protection. Don’t buy products with SPF values lower than 15, nor those without either zinc oxide or avobenzone for UVA protection.
9. No sunscreen towelettes or powders
FDA’s sunscreen rules bar sunscreen wipes and powders. But some small online retailers are still offering towelettes and powders. Don’t buy them. Why? Dubious sun protection. Besides, inhaling loose powders can cause lung irritation or other harm.
