I have used up 2 bottles of this and this ampoule has helped my skin significantly in brightening, moisturising and calming. Although the product contains actives like retinol, it is gentle enough on my sensitive skin. I only use it at night as it might be too moisturising for day time but I was still able to see great improvements in my skin after half a year of using it on my face and neck. My pores are much more refined, skin is no longer flaky and a few lines near my eyes are softened. And the best thing is this ampoule gives my skin a healthy glow and tone.
