Estée Lauder Brown Serum

Estée Lauder's famous "Brown Bottle" serum. It provides hydration without being sticky. It is on the pricier side, but I bought it during a big sale at a duty-free shop while traveling and gave it as a birthday gift to a friend. She likes it too and says it suits her well. Since it is a night serum, I usually only use it in the evening, but when my skin is very dry, I use it right after washing my face in the morning as well.
