Now let’s talk about my favorite serum out of the 3 has to be The Hyaluronic Acid 3 serum. I love the creamy, thick texture! Surprisingly, I barely notice any slip that you typically feel with a lot of HA serums. It does sink in quite quickly leaving a slight tacky texture. This does go away with the addition of moisturizer. I just love that this isn’t another HA serum rather a multipurpose hydrator with amino acids, ceramide NP, cholesterol, and caprylic triglyceride.

This serum has a lightweight yet thick consistency compared to the other two serums I tried in the set. It is clear in colour, has no scent and feels hydrating when applied onto the skin. It’s perfect to use during the dry and cold winter months as it helps to lock in moisture. I really liked it and found myself gravitating towards using this serum a lot.

This Hyaluronic Acid is hydrating; however it isn’t any more hydrating than some of the other Hyaluronic Acid serums I’ve tried. It’s not bad- it’s just as good as some other lower molecular HA.

I can't smell any scent of this serum! It tooks a couple minutes to absorb with a little bit sticky finish! But I can feel my skin is like plumps full of water so hydrating! Glowing! Hyaluronic Acid can locks the moisture! It can be great for winter time use with moisturizer!

This Hyaluronic Acid serum is lightweight and slightly viscous in texture. It feels initially cold upon application and refreshing at the end of the day. It glides over skin nicely but tends to leave a slightly tacky feeling after it sinks into the skin. Applying to damp skin helps the serum glide on more smoothly, sinks in quickly and leaves skin feeling less tacky. After each application, skin is left looking more plump, smooth, and less red. I found this serum to be great for my oily skin type as it penetrated and hydrated the deeper skin layers leaving the top layers looking more even without drowning my skin in moisture and making it look more oily than before. It was easy to incorporate it into my existing routine and paired well with all my products, even the actives, without issues.
