The Differences Between Physical & Chemical Sunscreen

The Differences Between Physical & Chemical Sunscreen
The more we know about skincare ingredients the better choices we can make. We all know the importance of wearing a sunscreen but it can easily become confusing and overwhelming choosing the best option. There are key differences between physical and chemical sunscreens so I have broken down the differences below to help guide you.  I recommend protecting your skin daily throughout each season and in addition to spf in your makeup.

Physical sunscreens: are also called mineral blockers, contain mineral ingredients, mainly titanium dioxide or zinc oxide, and work by sitting on top of the skin to deflect and scatter damaging UV rays away from the skin. They are great for skin types prone to hyper-pigmentation, sensitive, acneic, rosacea skin, and for children. Physical blockers are my preference and what I recommend to my clients.Bonus tip: I use LaDefense Urban Protect from Luzern as it contains an ingredient called Lutein which protects from blue-light emitted from our computer and smart phone screens. HEV or blue-light can penetrate the skin and cause skin damage similar to to that of UV rays.

Chemical sunscreens: contain UVA and UVB absorbing ingredients, such as oxybenzone, octinoxate, octisalate and avobenzone, and create a chemical reaction that changes UV rays into heat, then releases the heat. They take up to 30 minutes to activate once applied, so if you wait until you’re outside, you risk being unprotected in the sun for up to half an hour, and the sun damage adds up. Some people can get a sunburn in that time. If you don’t have 30 minutes, use a mineral SPF instead.

As the Kundalini yoga farewell blessing goes…May the long time sun shine upon you~
