SPF and Sun Protection – What You Need To Know

I can’t emphasise enough how important SPF and sun protection is. Research has made it clear that repeated, unprotected sun exposure not only puts our skin on the fast track to ageing but it also triggers skin cells to mutate and this in turn can lead to skin cancers. One of the most effective ways to prevent this is using a daily SPF.

Before we look into the different types of SPF, we need to understand the types of UV rays that cause the damage? There are two, UVA and UVB. UVA rays penetrate deeper into the layers of the skin and are far more damaging because they’re present all day long, year-round, they even come through windows. While you won’t feel the damage, it’s happening nonetheless. UVB rays are present with visible sunlight and are responsible for causing sunburn on the upper layers of the skin. Adding a broad spectrum facial sunscreen to your daily skincare routine, as well as being mindful of sun exposure, will help defend skin against both types of UV rays.

As to which type of SPF you choose? Physical Sunscreens contain active mineral ingredients such as zinc oxide and/or titanium dioxide and work by sitting on top of the skin to deflect and scatter damaging UV rays away from the skin. They protect against both UVA and UVB rays and once applied there is no wait needed. They are less likely to cause irritation on the skin, making it better for sensitive skin and they are also better for those with heat-activated skin (like those with rosacea and redness) since it deflects the heat and energy given off by the sun away from the skin. They are also less likely to be pore-clogging, making them ideal for blemish-prone skin types.

Chemical Sunscreens use a combination of active ingredients such as oxybenzone and octinoxate all of which absorb into the top layers of skin, where they work in two ways: by scattering and deflecting the sun’s harmful rays, and by converting UV rays into heat and then releasing that heat from the skin. These sunscreens usually have to be applied 20 minutes before going out in the sun. With chemical sunscreen there can sometimes be an increased chance of irritation due to the multiple ingredients combined to achieve broad spectrum UVA and UVB protection.

SPF what you need to know

Thankfully, the latest formulas are as smart and sophisticated as your favourite face cream and deliver great skin benefits. Whichever type you choose, and it does come down to personal preference, it’s crucial to use it all year round, rain or shine. Also worth noting, SPF15 filters out approximately 93% of all incoming UVB rays, SPF30 keeps out 97% and SPF50 98%. They may seem like negligible differences, but if you are light-sensitive or have a history of skin cancer, those extra percentages will make a difference. And as you can see, no sunscreen can block all UV rays.
