    Good Stuff 🌞

    Initially received as a bonus item thru Ulta many moons ago and gifted to my sister (42 y/o). She explained how great it works to bring life back to her "old," dry skin. I guess from here on out I'll continue to be her dealer with this stuff and keep her face rejuvenated!

    Refreshing serum

    I really enjoy how light and refreshing this serum is! I use it in the morning and follow with my moisturizer. I haven't had any redness or sensitivity to it, but I haven't used it long enough to see an improvement in any pigmentation. I like the citrus light smell and otherwise have been enjoying this products.

    Decent

    It's like any other vitamin c serum, you get most of the results you wanted. Just personally found needing to shake it annoying.
