Sun block/Sunscreen - Why do I need it if it's in my makeup?

I know many a person who tells me that they don't need sun block/sunscreen because it's in their foundation or moisturizer.

WRONG!

While it is good that your products have some sunscreen the problem is how much. There is no regulation in the USA as to the amount of sun block that must be put in a product for it to claim to have a certain SPF.

What does that mean?

The cosmetic company can put a few drops of sunscreen SPF 15 in a 20 ton vat of foundation or moisturizer and say that their foundation has SPF 15. Well, they aren't telling a complete untruth, there is SPF 15 but it is not necessarily effective. It may help some but not enough to actually protect the skin.

Why would a cosmetic company do this?

They are in business, there to make a profit, and sunscreen sells! True a few drops will protect you more than nothing however; it is not enough to keep age spots and premature aging at bay. Let's not even talk about skin cancer!

Why don't they put more sunscreen in the product?

Often times too much sun block will disrupt the makeup, causing it to break up or breakdown. I think, but do not know for sure, that a lot of the companies also know that on top of the sun block the foundation (depending on the thickness) will help act as a barrier between your face and the sun. It is true to an extent (see my blurb on cray-paper skin).

Bottom line:

What are a few extra minutes to your beauty regime vs. premature aging and ugly brown spots? Put on sun block after your moisturizer and before your primer (if you use one) or foundation (if you don't use a primer).

Your skin thanks you.
