No difference
I would not repurchase this product. I tried it for a couple weeks and felt nor aaw a difference. Even when applying it, it just felt like water. No hydrating going on.

This serum was really enjoyable to use. I found it to feel really refreshing and it sinks into my skin fast and leaves it feeling hydrated. Doesn't leave an oily or sticky feeling afterwards which I love. I wouldn't say it's my favorite but it's definitely worth trying and experiencing.
Hydrating, soothing and gives a beautiful glow

I really enjoyed the texture of this serum. At first, it feels very lightweight and almost watery, but as I massage it into my skin, it starts to feel deeply hydrating, almost like I applied a moisturizer. It feels soothing and leaves my skin hydrated for hours without feeling greasy. Compared to other hydrating serums I've tried, I really like the healthy-looking glow it gives my skin. However, I do think it may feel a little heavy on oily skin, especially if you prefer very lightweight products. I would especially recommend it for dry, dehydrated, or mature skin because of how moisturizing and comfortable it feels.

Lightweight Hydrating Serum with a Nice Cooling Feel

Thanks to EQQUALBERRY for sending me this Hyaltoin Flooding Serum to try for free. This fragrance-free serum has a runny consistency that spreads easily for even coverage and dries down to a natural, slightly hydrated finish without any sticky or tacky residue. It feels especially refreshing when my skin is a bit tight or dry after cleansing. The cooling sensation comes from the hydrating ingredients rather than anything irritating like menthol or peppermint. There's a slight grit from the tiny suspended beads, but they burst easily with the normal light pressure you'd use when applying any serum. Don't be put off by the natural blue tint in the bottle either because it turns completely transparent once it's on the skin. My face feels more comfortable right away, especially if I layer it a couple of times, though it still doesn't replace a richer occlusive moisturizer if you have dry or very dehydrated skin.
Great product!!

I was able to get this product for free in exchange for an honest review and I have been very pleased so far!! I have lost a lot of weight and loose skin has been a real issue. This product goes on so easy and absorbs nicely and makes my skin nice and plump. My fav part is it helps my makeup go on more smooth and even. It has zero smell which is also nice.
