I love Missha Time Revolution products. This is the second bottle I buy, now, a renewed version. What can I say about it? It doesn't sting even though you have sensitive skin, it supplies moisture and firmness, which is perfect as last step for your night routine. I also use this ampoule as serum for my needle treatment on my face. I prefer to use it just for the not too deep treatment, only for the surface needling, not bloody one. After that, I wake up with my skin surprisingly smooth and gummy. If you have a needle pen or roller, try it!
