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.

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.

Just buy it
Honestly I dont even need a spearate moisturizer. I apply this after washing my skin and then just apply my sunscreen. I would consider my skin type fairly normal.

Not your usual HA serum
it's very different from other HA serums. This one is white and not clear, I think because of the ceramides. This one actually makes your skin feel moist all day long.
