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 WaterPropanediol helps absorb ingredients into your skin, boosting their benefits. It can act as an emollient, making your skin softer. Propanediol can help products last longer by boosting the properties of preservatives within the formulation.
Propanediol is not likely to cause sensitivity and considered safe to use.
It is derived from corn or petroleum with a clear color and no scent.

Betaine is best for improving hydration and soothing irritated skin. Studies show betaine may help with uneven skin tones.

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.
