The best I've ever tried!
This vitamin C serum has been a game changer for me! (I have 34-year-old combination skin that is sensitive.) This gives me so much glow, a more even skin tone, and not to mention it's very economical to use. Tiny minus for the smell, but it disappears very quickly thankfully. I'm now on my second bottle and will never stop buying it🤩 (NB! Remember that this serum should be stored in the fridge!) #lykoreviewTranslated from norwegian

Combination with pink serum
Hi, Does it make sense to use this together with the pink serum from elixir in the morning? In the evening, I use retinext from elixir.Translated from norwegian
213 views- Customer service at Lyko1 weekHi! 🌞 Thanks for a great question! COSRX The Vitamin C 23 Serum can be used together with Elixir Pink Serum in the morning. They complement each other well – vitamin C works to even out skin tone and provide glow, while Pink Serum provides moisture and soothes the skin. Apply the vitamin C serum first, and let it absorb well before applying the Pink Serum on top. In the evening, it's great that you use Retinext – it creates a nice balance in the routine between active ingredients and care ✨ Just remember: ☀️ Always finish with SPF during the day when you use vitamin C and retinol in your routine. Feel free to reach out if you have more questions 💛

Damaged
Picked up the serum from the post yesterday, I'm basically very happy with this serum, but when I opened it this morning it was already completely yellow. When it has become so yellow, it no longer has any effect, disappointing with a brand new serum and now it's already useless.Translated from norwegian
343 views- Customer service at Lyko2 weeksHey there 💌 Thanks for letting us know – I totally understand that it’s frustrating when the serum looks discolored right at opening 😞 When it comes to vitamin C products, especially those with pure ascorbic acid, it’s actually completely normal for the serum to have a yellow/orange tint. This color doesn’t necessarily mean that the product is oxidized or unusable – it’s only when it turns dark brown that the effectiveness may be compromised. The slightly "tight" smell (which can remind you of fish oil) and the little puff sound upon opening are also completely normal – this happens because the product has been air-tight sealed according to recommendations to protect the vitamin C. A little tip to keep the serum in the best condition: Store it cool, preferably in the fridge ❄️ – vitamin C actually thrives best in low temperatures and dark environments. But if your serum is already dark brown in color, we’d love for you to send us a picture at kundesenter@lyko.com, so we can take a closer look at it together with you 💌 Wishing you a great day ahead!

No difference
I think this was a waste, I noticed no difference at all. The smell was a bit strange, I think it reminds me of self-tannerTranslated from norwegian
878 views- Customer service at Lyko1 monthHi! 😊 So sorry that this serum didn't live up to your expectations 😔 Thank you so much for your honest feedback – we really appreciate it 💛 Products with vitamin C can feel a bit different from person to person, both in terms of effect and scent. Hope you find a serum that suits you better moving forward! 🌿✨

Vitamin C and Elixir Niactil 4% and Elixir
Hi. I want an affordable and good vitamin C serum. Can this be combined with Elixir Niactil 4% and Face Formula (Elixir Cosmeceuticals) Balancing Hydration Cream? :)Translated from norwegian
735 views- Customer service at Lyko1 monthHey Camilla 👋 ✅ Yes, you can definitely combine: COSRX The Vitamin C 23 Serum with Elixir Niactil 4% and Face Formula Balancing Hydration Cream 👌 But here are some small tips for best effect and comfort: 🌞 How to use them together: Morning or evening: Vitamin C works great in the morning to protect the skin from free radicals throughout the day. Order: Cleanse COSRX Vitamin C 23 Serum Wait about 5 minutes (due to low pH, and to reduce the risk of sensitivity) Elixir Niactil 4% Face Formula Balancing Hydration Cream 💡 Note! A bit about the combination: Vitamin C and niacinamide (Niactil) can be used together – recent research shows that it is not necessary to avoid this combination, but some with sensitive skin may experience a bit of redness or tingling at first. Then you can alternate between morning and evening, or use Niactil every other day. Wishing you a nice day 💕

Unbelievable
The product is in a good bottle. I noticed that my face is more even-toned and the redness has gone away. I like the product and it's very long-lasting. Worth the price. 🥰1082 viewsto leave a comment - 1 monthRating: 4 out of 5verified customer
Lovely product, gets a deduction for bad smell
I've been using this for about a year now, very satisfied. The skin becomes soft and only needs light moisture on top.Translated from norwegian

Question
I am undergoing laser treatment for hair removal on my face, and I have recently started using the serum. Is this something that can be used even though I am having laser treatment?Translated from norwegian

Pretty okay
This vitamin C serum is pretty okay. It smells bad, leaves marks if you spill it, and separates often. It does the job it says it will.Translated from norwegian

How long does it take to see results against hyperpigmentation?Translated from swedish
3347 views- Skin therapist at Lyko3 monthsHey Alva! It's not possible to say any specific timeframe as pigmentation is one of the hardest things to treat with home care - it depends on how deep they are and what the cause of them is. For some, vitamin C helps a lot (along with UV protection every day and not being in the sun with your face at all), but you have to be patient 🙏 Sometimes if it's hormonal, like contraception being the cause, they can disappear if you stop introducing the hormones. Hope it gets better for you 😎

Description
Ingredients
Use everyday like a daily vitamin for your skin!
A gentle vitamin C serum that is suitable on sensitive skin to use daily! Regular use will fade blemishes, dark spots and freckles and improve overall tone.
Keeping products with high contents of pure vitamin C refrigerated is the best way to keep the vitamin C fresh.
This serum does not contain any added perfume. As COSRX uses natural vitamin C, the product may have a slight, characteristic odor. This is completely normal and a sign that the vitamin is active. The odor will dissipate quickly after application. A slight fizzing sound may occur when the bottle is opened – this is due to natural gas formation from the active ingredients.
Use:
Cleanse your skin and put a toner. Then apply few drops of serum to the skin. User fingertips to gently massage and absorb the serum, starting from the inside of the face working towards the edges
