Absolutely love this essence. Within the first few uses I noticed a visible difference in the appearance of my skin with my acne scars and other dark spots lightening substantially, and the overall appearance of my skin is healthier. I would say it has the consistency of a serum and it is slightly sticky but this is a pro for me as I find the texture works well with my serum and moisturiser which I apply over it. I am almost at the end of the bottle after using 1 or 2 squirts every morning and evening for about 8 months. I will be repurchasing soon!
