Most day creams and foundations now have SPF integrated in them. Is it really that important? Do I need to use an SPF if it’s not sunny? And if my foundation has SPF, do I really need to be using a separate SPF?
These are common questions I get asked. Believe me when I tell you, make SPF your BFF, and your skin will thank you forever!
So let’s start with the basics.
There are two types of UV rays.
These are the silent killers, the rays that are present even when it is cloudy and can pass through glass windows! UVA rays penetrate deeper through the skin, and contribute the most to premature ageing and skin cancer.
These are the rays that cause burning. The SPF number displayed on the packaging tells us how much UVB protection is provided.
So if I buy a broad spectrum SPF that protects against UVA and UVB is that enough? NO!
There are other elements that we also need protection against.
This penetrates even deeper than UVA and UVB rays, causing DNA damage and inflammation. It also causes early ageing!
It is estimated that more than half of the sun’s radiation is infrared. Just like visible light, it causes DNA damage and early ageing.
Ok, so we now know that we need protection against:
- VISIBLE LIGHT
- INFRARED RADIATION
My recommendation is Heliocare oil free gel. Heliocare products all contain protection against the above four factors. The oil free gel is fantastic for all skin types, even those who suffer from acne.
Make up containing SPF is unlikely to have protection against all of these factors, and therefore is not sufficient to protect your skin!
It is also important that you apply the right amount of the product, and the correct frequency. A general rule of thumb is that you should dispense a finger’s length of sun cream to cover your face. If you are using a product with SPF50, but you only use half this amount, it is essentially only giving you a protection equivalent to SPF25.
