What You Really Need To Know To Protect Yourself From The Sun

By now you have probably heard that you need to protect yourself from the sun! There are a lot of products out there that promise protection, but do you really understand the label or how to use it?

Here at Sanctuary Medical Center we offer a large array of sun protection to ensure we match you with a sunscreen that compliments your lifestyle.

We have an array of formulas based on skin concerns and conditions. Tinted SPF’s for our patients that want their skin to look better, SPF’s that offer moisturizing benefits, SPF’s that are water resistant, and SPF’s that effortlessly intergrade into your cosmetic routine.

Are Physical or Chemical Sunscreens Right for Me?

Let’s get one thing clear, not all sun blocks are physical. Chemical ingredients such as avobenzone and benzophenone, work by absorbing UV, therefore, reducing its penetration into the skin. Physical ingredients such as titanium dioxide and zinc oxide stay on top of the skin and deflect UV rays.

What Sun Protection Factor(SPF) is Right for Me?

The higher the SPF the better the protection, right? Not necessarily! SPF is a general measure of how long you can stay in the sun before the UVB rays start to cause the skin to burn. gives the example that if you notice that your skin starts to look red on average after 20 minutes of sun exposure and you apply SPF 30, theoretically you should be able to stay in the sun 30 times longer before you develop a sunburn. Sunscreen is one of the rare times that less is not more! More important than the strength of your sunscreen is that you remember to continually reapply throughout the day.

It is important to point out that SPF numbers are determined in a lab. In the real world, no matter what the SPF, sunscreens start to lose effectiveness over time, so it’s important to reapply every two hours and after swimming or heavy sweating. also mentions that additional sun protection is negligible past SPF 50.

The Skin Cancer Foundation recommends always using a broad-spectrum sunscreen with an SPF of 15 or higher – SPF 30 or higher for extended stays outdoors.


The terms “water-resistant” and “sweat-resistant” indicate whether the sunscreen remains effective for 40 minutes or 80 minutes when you are swimming or sweating. Since no sunscreen is fully “waterproof” or “sweatproof,” the FDA prohibits these terms.

Is It Important to Use a Broad-Spectrum Sunscreen?

According to, Ultraviolet (UV) Radiation is a part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. Ultraviolet A (UVA) is the longer wave UV ray that causes lasting skin damage, skin aging, and can cause skin cancer. Ultraviolet B (UVB) is the shorter wave UV ray that causes sunburns, skin damage, and can cause skin cancer. Broad-spectrum sunscreens, like all the options available at Sanctuary Aesthetic Medical Center, protect the skin against both UVA and UVB rays.
