I received a deluxe sample and was very excited to try this. I have combination skins I wanted a gel because they\’re lighter. Well, I applied way too much, my face was super sticky, I hated it and was just about to toss it until I looked and it and realized it was a concentrated serum. I washed it off and used a very small amount, what a difference! Super soft skin, no stickiness. I just put it under my regular sunscreen. Great product, just use sparingly
