Ree –
Great quality, easy absorption, daily glow, no sticky pre or afterfeel, works well, and it’s also a daily essential. Love it!
EllaB –
Fantastic Serum, a great addition to my moisturising regime, it’s very light in texture and it makes a difference, making it softer, brighter and more nourished.
Cecile P. –
I love this serum as it really makes my skin feel fresh and hydrated in the morning. This is my second bottle and will continue using it in combination with the vitamin C cream. It works well on sensitive skin. My skin feels smoother now.
