I add but I'm not sure

I received this in my BoxyCharm for the month of July. The price point for the item is midgrade and it would have to be purchased from the brand site or a department store I figure because it is not available at Sephora. I add a drop to my moisturizer every morning as the bottle indicates - I am not sure it is making a difference in the current appearance of my skin but if it keeps pollutants away moving forward I am all for it.
