The proprietary peptides come with studies and reliable anecdotal evidence to verify their effectiveness as amongst the best anti-aging and anti-wrinkle actives available to date.

    Small but mighty

    This is the first time i've tried an Inkey product and I'm so impressed! It really packs a punch. I've an unwelcome frown line that has recently become a permanent fixture on my face and within a few weeks of using this twice a day (once in the morning and again at night) it's hardly visible - even the boyfriend noticed!

    I’m always skeptical about cheap serums, but this one does not disappoint! After only a couple of uses, I could tell a difference in the texture of my skin. My skin feels more plump and full. This product is totally worth it, especially for how cheap and effective it is!

    Recommend For Everyone !

    Definitely worth it! I was surprised to see results using this product. After 25 there is a decline in our bodies regarding the production of collagen. Everyone should start using this, the sooner the better and it’s as good as other products I’ve used!


    Love! Just added to my routine and now its a must have.
