All Sunscreens Are Not Created Equal
Deciphering the terms and phrases on sunscreens can give you a headache. This blog attempts to clarify some of the more common items you will come accross and help you make wise decisions.
Reading the labels of sunscreen products is almost as important as food labels (and almost as fun.) But like food labels, a few minutes can make a big difference in your child's health. Let's start with the basics.
Let's note first that you should avoid being in the sun between 10 am and 4 pm when it is at its strongest. If you are outside during this time, please remember to cover up your skin, wear a broad-brimmed hat to cover face and neck, and stay in the shade as often as possible. When you do go outside, be certain to apply sunscreen approximately 30 minutes before you go.
Next, sunscreen is not only for the summer. You can also get skin damage during the winter, cloudy days, and through windows (car, house, or office).
In addition, skin color doesn't mean you cannot get skin damage from over exposure to UVA and UVB rays. Everyone should protect their skin as best as they can, including the use of sunscreen.
Finally, never try to tan or use a tanning salon. A suntan is a sign of skin damage.
UVA vs UVB
Ultraviolet A (UVA) has a longer wavelength and is associated with skin cancer and skin aging. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning and associated with skin cancer. If you see the term "Broad Spectrum," it means that the sunscreen protects against both UVA and UVB rays.
Mineral vs Chemical Sunscreens
Mineral sunscreens contain zinc oxide and/or titanium dioxide that sit on the skin and are not absorbed by the body. They are not as efficient as chemical sunscreens as it would take too much mineral which would make the lotion clumpy and spread unevenly. Chemical sunscreens are more efficient, but some of the questions are absorbed by the body. Also, Children's Mercy Hospital recommends mineral sunscreens.
For Babies
There is no distinction between babies and adults as far as the FDA is concerned. They all contain the same active ingredients and must meet the same standards.
SPF Ratings
SPF 100 is not twice as protective as SPF 50, so don't be fooled. SPF 100 blocks 99% of UVB rays, SPF 50 blocks 98%, and SPF 30 blocks 97% of UVB rays.
Water Resistant
The sunscreen will remain effective for the stated time, but you still need to reapply after sweating or swimming.
No Oxybenzone
Many sunscreens have already removed this chemical as it is harmful to ocean life. This chemical and octinoxate have been banned in Hawaii, the US Virgin Islands and other locations.
List of Terms That Have No Standard Meaning
Both are equally effective, if applied correctly. Sprays can be more difficult to apply as the droplets can disperse. You can overcome this by spraying your hand and applying it to the area. Remember, don't spray directly on your face and be careful when using the spray in windy conditions.
Cover Up to Avoid Sunscreen?
No, as you will still have exposed skin. Also, loosely woven material is not as effective as tightly woven material. Hold the fabric up to a light to see how much light shines through. Less light means better protection. For example, under a long-sleeved swim shirt or rash guard, you are safe. But don't forget to use sunscreen on the unprotected areas.
