I knew the principle of BB Creams without having them tested. I have very dry skin, dehydrated and fragile so I'm pretty wary about cosmetics. On leaving the tube, the BBC is grayish. It is only when applied to the skin it takes its real color. It is simple to spread, leaving no traces and a priori (and so far) I do not cause any allergy. So obviously, do not expect to get coverage of a foundation and because background ... BB Cream does not ... of a foundation. It is a complexion brightener. Then I will confess that personal, I used my old moisturizer before applying this BBC ... and I advise all those with dry and dehydrated skin to do so ^^ Anyway, I'll put it away in a drawer and out for the summer, when it's hot and all the classic foundation spin and do not take the shot.
