Ingredients Side-by-side
Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
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!
Learn more about WaterEthylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
Panthenol is a common ingredient that helps hydrate and soothe the skin. It can be found naturally in our skin and hair.
This ingredient is also referred to as pro-vitamin B5 or dexpanthenol in dermatology.
Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons):
Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

No irritation, no weird smell
I switched from Cosrx's Vitamin C 23 serum to this. I prefer this to Cosrx. It has no smell, no irritation and gentle to my skin. If you are a fan of Cosrx Vitamin C serum (but loathe the smell), you may want to try this too.

I've reintroduced this powerful vitamin C serum back into my routine because my hyperpigmentation has re-emerged. After only a few weeks of use, the dark spots and uneven skin tone have already faded and are much less visible.
Gradually increasing the vitamin C concentration in my routine, I've tried various other serums before - this one is the most effective so far. I'm not sure if I should explore higher concentrations, such as 30%, due to the risk of irritation, which may also be a concern with this one at 23%. So be mindful when introducing this highly potent serum. Isntree recommends using it only once every 3-4 days, and only at night.
The product oxidizes quickly and should be used within two months of opening. Tip: store it in a cool place, such as a refrigerator. It even makes a sizzling or gas tinkling sound when opened, reminding me of a mini bottle of champagne! The fluid has a clear, light consistency with a golden yellow shade. It absorbs very quickly, is not sticky, and is scentless. Plus, it’s cruelty-free.
