    Another Inkey Favorite

    I have been loving the Inkey List products like Ectoin Hydro-Barrier Serum and Exosome Hydro Glow Complex. I recently purchased the PDRN Serum which is awesome. All these are enhanced when you use the Hyaluronic Acid Serum and the Retinol Serum. The products really work and the prices can’t be beat.

    Age Wisely

    Yes, there is hyaluronic acid in virtually everything I put on my face (as a woman of a certain age). Still, I will go down fighting for my right to step out of my shower into a steamy bathroom and have step one be applying inkey's serum to my face. Does it work? I don't think I look a day over 65, even my baby sister--who is--would have to agree.
