I have very puffy under eye regions. This product is amazing! I use it almost everyday. I put a small dot on my finger and dab it on (about the size of a grain of rice). This lasts me about 6 months! It’s very obvious when I don’t use it. I put it on before my foundation, let it dry for about 5 minutes and then I put my makeup on. Be careful not to use too much or it will get a bit crusty. A little bit goes a long way!Great value! I highly recommend this product!
