Sunscreen Facts and Must Dos
Posted June 25, 2019 by Guest Poster - 4 comments
We all know that we need to wear sunscreen.
It has been proven to reduce your skin cancer risk and help slow down aging.
But there are so many different types and really…how often SHOULD we be reapplying it?
We went to the professionals at Stirling Skin Care Clinic and asked them to give us the basic facts on sunscreen. Here is what Rachael Watson (medical aesthetician and certified cosmetic laser tech) had to say!
Did you know that sunscreens and sunblocks are not all created equal?
Some fight UV rays with chemicals and some fight the harmful rays with minerals.
The ingredient list may contain: oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate.
Chemical sunscreens work by absorbing the sun’s UV rays, and then through chemical reactions, they dissipate the UV rays. Before these chemicals can offer any protection, your skin has to absorb them. This can result in irritation and discomfort, especially in adults with sensitive skin and children.
The ingredient list may contain: Zinc Oxide or Titanium Dioxide (naturally derived ingredients).
Mineral sunblocks sit on top of your skin and reflect away the UV rays. They are safe to use on all skin types, even the most sensitive.
What does SPF mean?
Sun Protection Factor (SPF) is how long your sunscreen/sunblock will protect you from UVB rays. UVB rays are what cause you to “burn”. They are harmful to skin’s outermost layers. This is where the most common forms of skin cancer occur.
Broad Spectrum SPF
This refers to sunscreens/sunblocks that block both UVA and UVB rays. It is recommended to always purchase a Broad Spectrum SPF because it’s the only way to be protected from both types of UV rays.
How much sunscreen should I use? A shot glass full for your entire body, and 1/4 to 1/2 tsp for your face.
Is my makeup enough? NO! Always apply a layer of mineral sunscreen under your makeup (even if it has an SPF rating). Reapply your sunscreen if you are sweating or swimming.
When should I put on sunscreen? 30 minutes before sun exposure and daily on your face (under makeup).
How often should I reapply my sunscreen? At least every two hours, but more often if you burn easily or have been in the water or are sweating excessively. You can also calculate what time to reapply by taking the SPF number and multiplying it times how long it takes you to feel like you are burning…but it’s usually best to just reapply every two hours or when you start to feel a need. You can’t overdo it!
