Physical vs. Chemical Sunscreen

Physical sunscreens such as Daily Physical Defense by SkinMedica, more commonly referred to as sunblock, contain active mineral ingredients titanium dioxide and/or zinc oxide. These ingredients which naturally give both UVA and UVB protection do not penetrate the skin but sit on the surface of the skin and deflect the sun’s rays. Chemical sunscreens such as Total Defense and Repair by SkinMedica, which do penetrate the skin, actually absorb or scatter the sun’s rays. Chemical sunscreens have a tendency to be more irritating to sensitive skin since multiple ingredients are combined to achieve the UVA and UVB coverage. Chemical sunscreens usually rub in easily while Physical Sunscreen can be a little thicker.

So, which one is better?

Physical Sunscreen is the ideal everyday choice, but it’s not waterproof and it must always be applied with your hands. Chemical Sunscreen is better if you are going to be exposed to the sun for extended periods of time because it can be offered in a convenient rub-free, water-resistant aerosol can. The most important point I would like to stress is one must be willing to wear sunscreen daily to protect your skin’s health and your aesthetic investment.                        

Protect your investment.

allysonI can not stress enough the importance of using SPF daily. Too many people think that they only need sunscreen when they are “going out in the sun”. All of those people don’t realize that the majority of sun exposure we get is incidental. When you walk out of your house, to your car, or any time (during the day) you are not wearing SPF,  sun damage is happening. Sun damage will occur in the form brown spots, broken blood vessels, wrinkles, fine lines, even skin cancer. If you want to look young for as long as possible, wear SPF daily.  If you are investing in Botox/Dysport , Filler, IPL, Chemical Peels, etc, you must protect your investment and wear sunscreen.  I am currently obsessed with SkinMedica Total Defense and Repair.  It is labeled a “Super Screen” because not only does it protect from UVA/UVB but also from infrared and heat.  It is the currently the only super screen on the market with this capability.  I also love the ZO Oclipse Sunscreen and primer.  It is a physical sunscreen, which means it does not penetrate, it sits on top of the skin.  It is a broad spectrum, SPF 30 that also behaves as a makeup primer.  (love it)
