  loves it

  i used to use Alchemie Forever HA serum which cost $75 for an even smaller bottle than isntree's… was looking for an alternative that wasn't so expensive and this is it. it's great and is comparable to the expensive one. will continue to buy.

  Deep, "drinkable" hydration- the ultimate moisture hack!

  If your skin feels "tight" but you hate heavy oils, this is your holy grail. It's the perfect base layer for any routine. A 10/10 for dehydrated skin types! Texture & Application This isn't one of those sticky, tacky hyaluronic acid serums that sits on top of your skin. The Ultra-Low Molecular formula makes a massive difference in the texture. It's incredibly lightweight and has a silky glide. I applied three layers this evening, and my skin completely absorbed every drop. Results & Finish The finish is exactly what I look for in K-Beauty: supple, shiny, and deeply hydrated. It gives that "plump" look to the skin immediately. Because it sinks in so well, it doesn't just provide a temporary surface glow; it feels like the moisture is locked into the deeper layers of the dermis. 14-Complex HA: You can tell there's a range of molecular weights here because it hydrates instantly but stays hydrated for hours. Zero Tackiness: Most HA serums leave a "film" if you layer them; this one remains completely weightless. Sensitive Friendly: No fragrance or irritation, even around the delicate eye area.

  Deep hydration

  I used several products from Istree have generally good user experience. Their products tend to be inexpensive but full of scientifically beneficial ingredients. This is one of those intriguing products that yield positive results on my skin. The serum has a watery runny touch and feel. It's lighter and thinner than most serum I used. Some would consider it a toner (they do have a toner in this collection). It is transparent and has no scents. If you don't read the ingredient list, you may not even know what you are using. The serum contains many different kinds of hydraulic acids which are interesting. Typically, the more ingredients a skin care product contains, the less likely the ingredients will blend well and be most effective. In this case, they are a variety of HAs... while I don't fully understand the science behind this, I do know the simple fact that HAs need water to do its trick. So when I apply this, I also make sure I use proper moisturizer to seal the hydration in my skin. It is easy to absorb, inexpensive, gentle and friendly to ance prone and dry skins alike. I'd endorse it over many brands that only focus on "feeling good".
