Let’s talk about the importance of SPF.
You will hear us discussing this a lot at the clinic, everyone asks us how to prevent skin aging and this is the number 1 thing we advise. We want to give you a little more information into why this is case.
Did you know….
UV damage is the cause of 90 % of skin aging.
Before I started in aesthetics, I didn’t know the difference between UVA and UVB. I used to think burning and direct sun was the only dangerous thing but with what I know now, I couldn’t have been more wrong.
The easiest way to explain the two types of rays, are thinking about the letter added on to them.
UVA – A being for aging.
UVB – b being for burn.
UVB rays are shorter in length, they don’t penetrate through glass, they are stronger in the sun and penetrate the outermost layer of our skin.
However, UVA rays are longer in length, they penetrate glass, they are around us all year round come rain or shine. This means that they penetrate deeper into the skin, causing wrinkles.
This now takes us on to the different types of sunscreen you can purchase. Here we only use mineral base ones but let me tell you why,
Unlike chemical sunscreen that penetrate the top layer of your skin and the UV rays are absorb, mineral base has bigger particles that sit on the top layer of your skin and reflect the UV rays.
There is some research out there on the negative impact of chemical sunscreen due to your skin absorbing it, however none of it is as of yet conclusive. There is evidence to suggest that chemical sunscreen is bad for the environment in the sea due to the chemical disrupting coral reproduction and growth.
Mineral sunscreen provide protection against UVA and UVB rays, evidence has proven they are less likely to irritate sensitive skin and to exacerbate acne and rosacea. In relation to any melasma or hyperpigmentation it is also best used as it reflects light rather from the skin rather than absorbing it like chemical sunscreen, which can actually make melasma worse.
Using an SPF 15 in your make up will not be providing you with enough coverage, it needs to be a factor 30-50 every.
Even though some SPF have a little moisture in it, for best results for your skin a moisture should be used first then your SPF afterwards.
