I've had samples of both 8% Sienna x and the 8.5% Sienna x Q10 and tbh, can't decide between the two. Can any Sienna x users say which they prefer/use most of? I can't afford to stock both.
Hey, i use the 8% i have never used the 8.5% because ie v heard it can be abit drying on mature skin. other people might have more info and expierence on it tho
I too have stuck with the 8% purely for the nice simple ingredients, colour wise i personally believe there is next to no difference. I know the 8.5 is designed to be a little more anti ageing but i personally haven't seen this.
