The Vitamin C23 Serum

product review positives
I was lucky enough to selected by Cosrx to review one of their three new Derm Serums. I was gifted the Vitamin C23 Serum which I have been using for about 12-14 days so far, so this will be more of a 1st impression review. Update 9July: I found out a week after I received the Vitamin C Serum from Cosrx that I had also been chosen for a StyleKorean TMRM promotion & would receive all 3 serums, so I was extra lucky as I had a good first impression of this serum and now I have 2!! This serum is described as a highly concentrated 23% pure vitamin C serum that provides the anti-aging benefits of Vitamin C with minimal irritation. I was excited to try this serum since I have some sensitivity to Vitamin C products with a high percentage of L-ascorbic acid. Claims: ▪️Fades acne & hyperpigmentation ▪️Brightens complexion & evens skin tone ▪️Diminishes fine lines & wrinkles ▪️Firms & plumps skin Key Ingredients: ▪️Ascorbic Acid (Vitamin C) ▪️Tocotrienols (Super Vitamin E) ▪️Sodium Hyaluronate ▪️Allantoin Packaging: 20ml dark brown bottle with glass pipette Texture: Oil with watery consistency, pale yellow in color. No added fragrance but has the same scent as other Vitamin C products that fades quickly. PAO: 2 Months. It is suggested to refrigerate to maintain freshness My Experience: I’ve been using this in the AM only, before moisturizer and sunscreen. I apply 2-3 drops into my hands and massage into my skin. It is very lightweight, & spreads easily onto the skin. I do feel a slight tingle after application, while it isn’t sticky, it does feel a little tacky on the skin until it fully absorbs. It also layers well with other products, without any pilling. I had heard of Tocopherol (Vit E) before, but not Tocotrienols. I did some research and found out that they are also potent forms of vitamin E that are considered stable and powerful antioxidants. Tocotrienols have skin soothing agents & helps even skin tone. When combined with Vitamin C, it in double the antioxidant ammunition to fight damage from free radicals and more UV damage than products containing vitamin C by itself. Sodium hyaluronate attracts moisture & reduces inflammation. Allantoin soothes and protects the skin & reduces irritation. It also has some other great antioxidant ingredients like 3-O-Ethyl Ascorbic Acid, Caffeine, Tocopherol, Safflower seed oil, & carrot root extract, as well as brightening ingredients like niacinamide & licorice root extract. I have not experienced any burning issues & no irritation so far. I have not noticed any significant improvement in hyperpigmentation yet in the short time I’ have used this serum, but my skin appears brighter & more even toned. I will definitely continue to use to see the long-term effects. UPDATE 9July: I’ve now been using this serum for close to a month (AM only). I’m now using it daily, applying 2-3 drops onto my skin. When I first started using the serum, I did feel a very slight tingle after applying, but don’t notice anything now, other than a slight tacky feel on the skin until it completely absorbs. It does have that funky smell other Vit C products have (meat/iron scent), but I’m used to the scent, and it fades quickly. Packaging reminds me of The Ordinary. I have noticed that my skin looks brighter & more even toned with a smoother texture. I’m also starting to see slight reduction in dark spots as well.
product review negatives
I had no issues although it does contain alcohol denat. However the rest of the ingredients are nice It only has a 2 month PAO and will be hard to finish in so short a time.
