High percentage w/ gentle formulation |
| fly...@ |
My second favorite Cosrx serum has to be the Vitamin C 23 serum. This was my first time dabbling in a high percentage vita C serum. I had no problems; however, I do not have very sensitive skin so take it with a grain of salt. I have only used this sparsely since I have been in the sun a lot. Every time I used it in my PM routine, I had no irritation or reaction. I did notice a mild bit of purging after so first used it. I love that this formulation also contains many great hydrators, panthenol, squalane, and sodium hyaluronate. I find it’s slowly helping reduce my hyperpigmentation. I will have to produce an update when I have to finish the serum in 2 months! My only big qualm with this serum is it’s very tacky. Thanks to my Instagram friends I find the best way to use this serum and reduce the tackiness factor is by adding this product first before toner.

high concentration of vitamin C |
| min...@ |
The highest concentration of serum for Vitamin C! This Vitamin C serum is tinted yellow and feels a bit sticky when applied. I am not a fan of the smell of this product, it reminds me of metal. However, when you apply it, your skin feels hydrated and glowy. This serum doesn't have a long shelf life as it will oxidize; it has to be used within 2 months after opening. I haven’t used this product long enough to see results like acne scars fading.

Very Brightening! |

I really like this stabilized form of vitamin C. It appears to be stronger but not harsh or damaging. My skin really looks a lot brighter and more healthy.

Vitamin C |
| man...@ |
Maximum effectiveness with minimum irritation! Highly concentrated, 23% pure vitamin C serum that fades acne scars and brightens complexion to revitalize dull and dry skin.⠀
Benefits:
Fades acne scars & hyperpigmentation
Brightens dull skin
Diminishes fine line & wrinkles
It is really interesting when I first opened this serum, It sounds like opening a soda! This should be really fresh Vitamin C serum! It is like a light weight fish oil texture! The smell is also like fish oil! The color of the serum also is golden color like oil! But it absorbed quickly when applied on the face! Not as heavy as I expect when I first test that texture on my hand! It is great to use with The Hyaluronic Acid! Not irritation！My skin has a bit of acne marks. I look forward to keep using it to reduce more of my acne marks!

Potent but non-irritating |

This Vitamin C serum has an incredible oily texture but glides beautifully over the skin and sinks into the skin quickly without feeling oily or heavy. Skin feels noticeably smoother and lightly hydrated after application. I experienced no tingling or warming sensations after application, even though the serum has a very high concentration of vitamin c.
Despite the initial oily texture, I found that this serum slid easily into my morning routine and didn’t cause any pilling with my sunscreen, which is a problem I have encountered before with oils.
After a few applications, I noticed a slight improvement in my post-acne inflammation but would have to use it more long-term to gauge its effects on acne scarring and signs of ageing.
