Humectant, Skin Conditioning

Sodium Hyaluronate is hyaluronic acid's salt form. It is commonly derived from the sodium salt of hyaluronic acid.

Like hyaluronic acid, it is great at holding water and acts as a humectant. This makes it a great skin hydrating ingredient.

Sodium Hyaluronate is naturally occurring in our bodies and is mostly found in eye fluid and joints.

These are some other common types of Hyaluronic Acid:

I've tried about 5 different Vitamin C serums, and this one is by far my favorite. I've purchased it 3 times. (I started using it back when it was the dropper bottle)

My skin can tolerate higher Vit C percentages very well, so this feels like nothing on my skin. As if I was putting on water. I don't mind the ferulic acid smell (which is noticeably less now than it used to be!), because I think Show more

Did a patch test on my arm to see if it works for hyperpigmentation - tried for 3 days (once a day) and my arm had small pimples/ irritation bumps! I never have breakouts on my body.
Don’t know if the concentrations are too potent (even for the body) or the formulation is just bad.

I think this is one of the best serums for hyperpigmentation IF you are a BEGINNER (keep that in mind), I have sensitive skin and I find it very soothing but didn’t see much results.
Also this serum is quite sticky so I recommend you that after you apply it on your face, leave it for 10-15 minutes so your skin can fully absorb the product. Then you can use other products as you wish. Hope it Show more
