Nice & Hydrated!
I was looking for a new H.A. to put in my skincare routine. My skin is typically sensitive, but soft and clear with no blemishes. I use a prescription retinoid on my skin to prevent wrinkles and my skin was drying out and dehydrated lately from it. Yikes! I picked this H.A. serum to try to help and it's a winner! Been using for over a week now and I've seen instant improvement. Skin is well-hydrated. The dryness I had from my retinoid has reversed. No more peeling. No dehydrated-wrinkles. I definitely needed this serum. I'm back to a plump and bouncy feeling to my skin! I use this after cleansing off my makeup and then spray my entire face with distilled water and let it sink into the skin at night. I will say--I don't use this in the morning because it does feel a little sticky on my skin. One day I goofed up when drawing on my black winged eyeliner and it was tough to rub off the black eyeliner and make a nicely-drawn line again with this serum on. But don't be scared that this is a Korean skincare brand--it seems like legit hyaluronic acid with a nice viscosity and I'm super picky with my sensitive skin products! Will order again :)

Intense Hydration for Smooth, Visibly Plumped Skin
The Pure Hyaluronic Acid 1% Powder Serum is a hydration powerhouse, offering a concentrated formula with 10,000ppm of hyaluronic acid to quench and visibly plump the skin. This serum is ideal for those dealing with dryness, fine lines, or anyone looking to give their skin a youthful, dewy glow. The texture of this serum is lightweight and absorbs quickly without leaving any sticky residue, making it easy to layer under other products or makeup. After consistent use, I noticed an immediate boost in hydration, and with continued use, my skin appeared smoother and more supple, with fine lines visibly softened. With a generous 4 fl oz size, this serum is great value for anyone looking to incorporate hyaluronic acid into their routine without frequent repurchasing. The serum’s formula is straightforward and gentle, suitable for even sensitive skin, and pairs well with most other skincare ingredients, making it a versatile addition to any regimen. For those in need of an effective, no-nonsense hydration boost, the Pure Hyaluronic Acid 1% Powder Serum delivers intense moisture and visibly plumps the skin, earning it a spot as a skincare staple.

Works great - very moisturizing & non greasy. Absorbs well.
I've been using this brand of hyaluronic acid for quite a while now. I use it every day just after washing my face or showering. It's a great, affordable way to get moisture deep into the skin. It's very light, not sticky or greasy at all and a little goes a long way. One pump is all I need for my face. Like all pure hyaluronic acid - it needs to be followed up with another moisturizer since it really gets soaked into the skin. I love it and will continue using it - as it's very effective and affordable. I've tried other brands and I like this one the best.

Switched from The Ordinary
A little goes a long way. Transitioning from The Ordinary's HA serum. Worked well for microneedling but still kinda broke out the next day. Provides lots of slip. Seems to pair well with other products but this product alone does Not cut it as a moisturizer. Def better than The Ordinary tho

3 years and counting
This is my 2nd time purchasing this product after seeing a tutorial about micro needling on YouTube. Using it during the process has been great! It's thick and seems to help with dryness after needling. I've gone through 1 small bottle over the past 2 years & decided to go with the larger bottle this time around. Its well worth the price!

Perfect. Its quite thick so either combine with water or just leave overnight. Works for microneedling, but may form lumps or peel , especially if used with other serums. Dw, just wipe it off and put fresh layer. A little goes a long way, been months and still have more then half bottle
