I really enjoyed this serum. It is very light, so it suits me perfectly in the morning routine. It has a light aroma that disappears right away.
I use it mainly after my toner in a good amount and I let my skin absorb it. It is extremely moisturizing and leaves the skin fresh and smooth.
Now, I've used almost half of my jar and I've had enough with it, so I'm sure it'll give me about 6-7 months. The price is quite cheap, so for less than 10usd is a bargain.
