I use this serum in the PM routine around 4-5 pumps for face and neck. What I love about this serum, its provides very good hydration to my skin. It's insane the moisture! This serum makes my skin feel very smooth, soft, and plumpy. I really love this serum because it gives a beautiful glowy to my skin overnight. Even when I wake up my skin looks so radiant. There is no bad reaction after using it. If you need a serum that gives an instant glowy, you worth to try this one.⁣⁣⁣
