Amazing and potent |
| all...@ |
I will fully admit to being nervous about trying this one. 23% Vit C was more than I have used, ever.
There was no need for worry. I’ve been using this nightly, & already seeing wonderful results. I store it in a cool place, follow all directions on the packaging. I was so impressed with the care taken in this packaging & in the detailed directions enclosed. Thank you Cosrx. That gave me comfort.
I feel a slight tingle when I apply this sometimes (more so if I have exfoliated recently), it goes away quickly, & I’m left with a slight warmth on my skin. They truly were able to deliver a high potency Vitamin C serum, that does not have a negative effect on my skin. Much lighter weight than I expected, & absorbs so quickly. I started with just a couple drops, but have worked up to about 5 drops & no oily feeling at all.

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 |

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!
