    Helped a lot with dry patches

    I have pretty dry skin, especially around my cheeks and forehead, and most serums just didn’t do much for me. But I started using Plump every day and the difference is noticeable. The flakiness is gone and my face doesn’t feel tight anymore. I use it right after cleansing and before moisturizer, and it layers really well with everything. Doesn’t leave a sticky feeling either, which is a win.

    Skin is so smooth!

    I absolutely love how smooth and glowy my skin got after applying this serum. My skin absorbs it so well and I like how it comes with a good amount of product inside the packaging. Highly recommended

    So good!

    Super happy with my serum! I love how it’s creamy and it’s non sticky! Also like the fact that you can use this as primer for make up!

    Great for dry climate

    Living in a dry climate has always been tough on my skin. Since incorporating Plump into my regimen, I've noticed a significant improvement in hydration levels. My skin feels plumper, and even some of the fine lines around my eyes have become less noticeable. It's gentle enough for my sensitive skin, and I love that it's fragrance free.

    Milky, hydrating goodness

    Not all hyaluronic acid serums are made the same and this one is WOW! You can experience smooth, hydrating skin immediately after it absorbs! Follow with a cream/lotion to seal in the goodness and you are good to go!

    Actually keeps my skin hydrated all day

    I’ve used a bunch of hyaluronic serums before, but they either felt sticky or just kinda sat on my skin doing nothing. This one’s different. It sinks in fast, feels super lightweight, and my skin actually stays soft and hydrated all day. I’ve been using it morning and night under my moisturizer and I swear my skin looks plumper. No breakouts, no weird texture, just works.

    Super Hydrating

    I use this as part of my makeup prep. My skin isn't very dry, so a small amount covers my whole face, even under my eyes. It adds amazing hydration in just a minute and leaves my skin feeling silky. Since it's oil free, my makeup stays in place all day without sliding, even if I sweat a little. It could work well as a daily moisturizer too, but I love it as a base for makeup. It never leaves any residue or stickiness like other products I've tried. I really trust this one!

    Huge difference

    I noticed a difference right away after starting this product. My skin is very dry, and this has truly made a huge difference. The redness and peeling have improved so much, and I hardly deal with those issues anymore. I can't recommend it enough. Amazing product, thank you Serum Junkie!!

    Dewy skin

    I've been using this for a few weeks and my skin has never felt so hydrated and plump. It absorbs quickly without any stickiness and leaves my skin with a fresh, dewy glow. Just a small amount does the job, and it works perfectly under makeup and other products. This has become a must-have in my routine.
