    Thank you Inkey!! The best Polyglutamic Serum by far. It's like silk on the skin.

    So Inkey lowered the price and I'm buying it like it's the apocalypse! Love this stuff folks. It's magic for the !mature woman's skin. I cannot over estimate the power of this little product. Mix this with Estee Lauder double wear and WOW! For dry mature skin, it's a wonderful addition. I use it under my makeup every day and I love it. It's the serum that hydrates all day and leaves your skin super soft. This stuff is great under eyes, on the neck, all over the face. I don't overuse it, but I love it. I hope to never be without it. Thank you Inkey for lower the price! You made this woman happy!

    My skin feels very moisturised and soft when I add this to my routine. It has an unusual smell which I’ve grown to love!
