This serum is my favourite! I use it in the nighttime before retinal and sometimes in the morning. It is a thicker serum, so some might not like the texture itself, but it is incredible. You have to give it some time and you will notice the difference in you skin. It definitely strengthens your skin barrier and gives you a healthy glow. After a month, I also noticed that my skin is even more firmer and it also works great for my acne-prone skin. It never broke me out or irritated my skin and caused a reaction (since I also have contact dermatitis). So, truly a product worth trying!
