    It feels tacky on my skin. But it does deliver.

    Absolute staple

    I’ve repurchased this serum consistently over the last 4 years. Initially it was to control my acne breakouts, which I now rarely get, but when I try to phase this out, always one or a few little pimples will try to pop up. Since then I keep at least two backups!
