With the warmer weathers approaching, protecting your skin should be of top priority while you’re out and about during the heat of the summer. Most exposed and vulnerable to harmful UV rays are all who spend extended periods of time outside – playing, sporting, hiking. Sunscreen provides protection from UV radiation and is essential in your skin care routine to avoid burns and redness. 

Sunscreen protects your skin by absorbing and/or reflecting UVA and UVB rays. The SPF rating system was developed back in 1962 by Franz Greiter to measure the capacity of a sunscreen to block UVB radiation. Unfortunately the current SPF rating system applies to UVB rays only, since those are the rays that cause sunburn. A huge factor in damaging the skin is also UVA radiation. We don’t feel the effects of UVA rays because they don’t cause sunburn. They penetrate deeper into the skin and cause bigger problems – skin cancer and wrinkles.


Look on the label for UVA-protecting sunscreen ingredients like titanium dioxide and zinc oxide (physical sunblockers).


Physical sunscreens can be helpful for anyone with sensitive skin or even repair damaged or dermatitis prone conditions, since they’re less likely to exacerbate irritation and redness. That said, if you do prefer the idea of chemical-free sunscreens, there’s one ingredient to look for – zinc oxide – a mineral that prevents UVA and UVB light from entering skin and doing damage. Zinc oxide is a physical blocker, the only ingredient you need for excellent broad-spectrum protection, says David Hershthal, a professor of dermatology at the University of Miami Miller School of Medicine. You also want to make sure that the zinc oxide in your sunscreen is uncoated, non-nano, and not micronized. This all means that there are no nano-sized particles entering your body, which many (mineral) sunscreens certainly cannot claim.


Do super high SPF numbers really give you more protection?


The answer is YES and NO. It all depends on how much sunscreen you use and how often you reapply. The mistake people often make, is not using enough sunscreen! No matter what SPF your sunscreen is, you’ll still get a burn if it’s not properly applied. Also, water resistant doesn’t mean waterproof, you should reapply your sunscreen every 1-2 hours! 


There is very little difference in added protection, as the protection factor numbers go higher. Whatever the SPF, you want that layer of sunscreen on your pretty face to be generously thick to provide maximum protection. Remember – there is no such thing as 100 % sun protection in sunscreen.

Keep in mind that sun-protection does not increase proportionally to an increase in SPF (Sun Protectin Factor). That means that higher SPF number doesn’t necessarily provide better protection. 

For example:

SPF 2 blocks 50% of UVB rays

 SPF 15 blocks 93% of UVB rays

SPF 30 blocks 97% of UVB rays

SPF 50 blocks 98% of UVB rays

The Academy of Dermatology (AAD) recommends the sunscreen you use must be at least a Sun-Protection-Factor of 15+.  For outdoor activities use sunscreens with at least 8-10% Zinc Oxide and an SPF-30+. Waterproof or water-resistant sunscreens for the hottest days of Summer or for sports – these won’t sweat or wash-off easily. Re-apply often.


At VACA CARE we started our skin-care business by making cosmetics for us to use and we still go a long way to produce maximum safety and efficacy for others too! A great zinc based sunscreen leaves your nose a bit whitish but this is rather a good thing. The more coverage – the more UV-rays it reflects back. VACA CARE ZINC FACE PASTE has 18% zinc oxide and 2% titanium oxide in it which makes about SPF 25. 


Now get out there and enjoy the weather by making a mineral sunscreen your new best summer friend!
