Review: Instant Glow - I’ve only used this product for a few days, but I can already tell a difference, which is crazy. As soon as I put it on, it gave me an instant glow—not oily, greasy mess kind of glow, but the healthy, plump kind of glow. As someone who had beautiful skin during pregnancy, but is now struggling with uneven and dull skin tone postpartum, this made me extremely happy. Anyway, here are my initial thoughts: Formulation: •this contains a high ascorbic acid percentage. I’ve never been sensitive to ascorbic acid, so my skin does well with the high concentration. However, if you have more sensitive skin, consider starting with their other vitamin c serum that has a lower percentage of vitamin c. •there is no ferulic acid present, which is generally used to stabilize ascorbic acid. Without this, I’m afraid the product won’t last terribly long without oxidizing, so keep this in mind. The instructions do say to refrigerate after opening, which may help slow down oxidation. Texture: The texture of this serum reminds me of a bi-fácil product where there is an oil layer and water layer that need a little shake to incorporate. Don’t let the oiliness scare you though, it does sink in to the skin well and doesn’t feel heavy on the skin. I haven’t had any issues with pilling when I’ve applied other products and makeup on top. Smell: As many reviewers have mentioned, it does have a particular smell to it. To me, it reminds me of tuna, which is quite unpleasant. However, it does dissipitate quickly. I just hold my breath while I apply it to my face XD I don't smell it at all throughout the day.
Review: Great value - This serum works really well. It also is affordable . The only complaint I have is that it smells terrible. Thank goodness the smell dissipates almost immediately. It does the job though and it's makes my skin brighter.

### ⭐⭐⭐⭐ Could cause acne
*by N***A on June 8, 2025*

I've been a huge fan of Cosrx products. I originally had used the lower strength of vitamin c and upgraded to this one a few months back. I feel that it does work in terms of discoloration, but for some reason this one makes me break out more than other vitamin c products I've used. I'm going to finish up what I have left of this bottle but I think I'll go back to the lower strength. My only complaint with the Cosrx vitamin c is how small the bottles are. It could be because vitamin c doesn't last long in terms of potency once opened, but it's a bit pricey for such a small bottle. You definitely have to keep it in the fridge and the smell is strange and not very pleasant but goes away shortly after application. I have not noticed any stinging or irritation from this higher strength vitamin c, but like I said, I have noticed acne break outs happening a bit more than before. My recommendation...give it a shot if you've already used the lower strength and feel you need more potency, but beware of potential break outs.
