Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

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

It’s okay I guess. It’s very expensive and doesn’t do anything a much cheaper serum can’t do. I’d recommend cosrx vitamin c 23 serum for the same benefits at a fraction of the cost.
