Secretderm BB Cream

I'm using this Secret Derm BB cream that I found late in a corner. It's on the matte side, so I mixed it with pure hyaluronic acid; it applies thinly, keeps my makeup from smudging all day, and provides good coverage. I tried to repurchase it, but found out it's discontinued... It's a bit past its expiration date, but I haven't had any issues, so I plan to keep using it. It was in the cosmetic refrigerator, so it should be fine, right!? Heh
