First off, let me say that a little goes a LONG way! I’ve had this serum for over a year now, I use it only at night and it’s lasted me so long. It’s extremely moisturizing, and I use it as my last step in my nightly skin care routine. It’s a little more oily than what I usually prefer, however it’s such great product that I’ll let it slide because it’s never once broken me out and it keeps my skin soft and dewy :) Absolutely a staple in my skin care routine!
