What is SPF?
Did you know that SPF does not express a specific amount of sun protection, but rather suggests how long it will take for skin to redden in comparison to skin without sunscreen? Let’s take an SPF of 15, for example: On average, it would take up to 15 times longer for skin to show signs of sun damage, a.k.a. redness, than it would without any SPF. Keep in mind, that you should reapply sunscreen at least every two hours regardless of SPF. The lobster look doesn’t really work for anyone!
Did you know sunburn’s are primarily caused by UVB rays, while UVA rays are responsible for premature aging. Therefore, SPF measures the amount of UVB rays being blocked. To protect yourself against UVA radiation and premature aging, look for sunscreens labeled as broad spectrum.
The importance of sunscreen
This is why it is important to use sunscreen daily, even if you’re just going outside for a run. For example use, Yon-Ka SPF 25 Broad Spectrum / Sunscreen Cream to keep your skin and face protected. Many people think that they don’t need to use it because they don’t burn easily, but that’s not the case. Anyone that is over six months old should get in the habit of using sunscreen daily.
To make sure you are fully covering your body, you should use about 1 oz every 2 hours. According to The Skin Cancer Foundation, “Studies show that most people apply only half to a quarter of that amount, which means the actual SPF they have on their body is lower than advertised.”
Keep your skin protected to avoid premature wrinkles and damaging sunburn, your skin will thank you later!
