Works!!
I combine this with Dr. Althea's 345 Relief Cream 50 ml, and they go perfectly together! 💗 I first tested them from my mom's routine, and saw very quickly that I had to buy both products myself 😂🤩 It hasn't been long since I started using them, and I've already used up both the first bottle and the first tube 😅🫶🏻 I see such a big difference, and my skin has never looked or felt better. I have acne-prone and oily skin, and my skin doesn't react to these at all ❤️❤️ Highly recommended!😍✨❤️ #lykoreview2693 views - The user's roll: Lyko Creator.

My honest review: COSRX The Niacinamide 15 Serum
Are you looking for the best serum to shrink pores and reduce acne scars? COSRX The Niacinamide 15 Serum 20 ml is a real powerhouse that has worked wonders for my oily and acne-prone combination skin! What I like best is how quickly it calms redness and keeps stubborn blemishes and breakouts in check. Thanks to the extremely high concentration of 15% niacinamide, I’ve noticed my enlarged pores have tightened up and my stubborn acne scars have faded significantly. The serum regulates sebum production without drying out the skin, and it leaves a fantastic, subtle glow that doesn’t look greasy. It feels active on the skin upon application, so ease into it gently – but the results are definitely worth it! #lykocreator #beauty #lyko #lykoview #skincare123 views - The user's roll: Lyko Creator.

COSRX The Niacinamide 15 Serum 20 ml
Have been using this for a while now, I notice my enlarged pores have become smaller. Definitely think it will get even better over time. I use it in combination with Medicube Triple Collagen Cream. A nice glow that doesn’t look greasy. Works well with makeup. 👍🏼 Planning to buy retinol from the same line. Nothing negative to say about this, a good purchase. #cosrx #lykoreview377 views - The post was made 2 monthsRating: 5 out of 5verified customer
Perfect for uneven skin!
The product plumps the skin in a nice way. Works perfectly for me with sensitive acne-prone skin and leaves an evenly nice face that is usually very pitted from scars. Perfect under makeup!551 views - The post was made 2 months
Step in skincare routine
Hello, I have bought the following products from you Bioderma micellar cleansing gel Pyunkang Yul moisture ampule Jorgobe niacinamide serum 5% Corxs retinol 0.1 Klair fundamental eye butter P:rem safe me relief cream How should I best use these products together? I have combination skin with a shiny forehead and slightly larger pores around the nose as well as a tendency to redness. Thanks in advance 🙂395 views- The user's roll: Customer service at Lyko. The comment was made 2 monthsHey Alfred! 👋🏽 What wonderful products you’ve clicked home! 😍 Here is an easy way to use the products together 👇🏽 🌞 Morning Bioderma Micellar Cleansing Gel Pyunkang Yul Moisture Ampule Jorgobé Niacinamide Serum 5% Klairs Fundamental Eye Butter Make P:rem Safe Me Relief Cream ❗ Always finish with SPF during the day ❗ 🌙 Evening Cleansing Pyunkang Yul Moisture Ampule (2–3 evenings/week) COSRX Retinol 0.1 Klairs Eye Butter Make P Relief Cream Start gently with retinol (2–3 times/week) to avoid irritation and redness. Niacinamide is great for shiny forehead and pores. If the skin feels sensitive, skip retinol that day and focus on moisture. This is a balanced routine that works on pores, shine, and strengthens the skin. Have a lovely day! 🌞

Really good
Really effective product, thanks to this my acne scars have lightened🩷586 views 
Rating: 5 out of 5Such a good and pleasant serum
This is a really powerful serum for those who want to work on skin texture, enlarged pores, or shine. With a concentration of a whole 15% niacinamide, you quickly notice the difference in how the skin balances and gets a more even tone. What I especially like is that it also contains zinc, which really helps keep impurities in check. The formula is light and absorbs well, but since the concentration is so high, it can feel a bit "active" on the skin right upon application. It’s not for the most sensitive skin, and you should ease into it carefully. The bottle is quite small (20 ml), but since you only need a few drops, it still lasts a while. A top choice for those with combination to oily skin who want visible results!695 views- The post was made 3 months
Combine with
Hi, Can I combine this serum with torriden dive in hyaluronic serum? Thank you670 views- The user's roll: Employees at Lyko. The comment was made 3 monthsHello Jessa😊 Yes! You can safely combine COSRX The Niacinamide 15 Serum with Torriden DIVE‑IN Hyaluronic Acid Serum. Apply the niacinamide serum first on clean skin, then layer the hyaluronic acid serum for extra hydration. On days where your skin feels drier you can also reverse the layering order – they work well together and are gentle on the skin. Hope this helps and wishing you a great day💫1 likes

Full hit
This is one of the best serums I have tried! I think this is comparable to the serums I have tested from Medik8, even though the price differs significantly. As soon as I get tendencies for blemished skin, I use this for a few days and then there are no major breakouts 😁 it works well regardless of whether my skin is dry or oily. The serum has no scent, so it suits everyone regardless of preference in that way 🤭866 views - The post was made 7 months
Against acne
Hi! I use Niactil 4% from Elixir against acne and it works really well. Is this a good supplement to the routine, or will they do too much of the same? :))1433 views- The user's roll: Employees at Lyko. The comment was made 7 monthsHi there!💚 Since you are already using Niactil 4% with niacinamide, there’s no need to add COSRX The Niacinamide 15 Serum — it might be too much of the same.

Becoming a little dry
I have started testing this routine: First: The Niacinamide 15 Serum 20 ml Then: Advanced Snail 92 All In One Cream Tube 100 g I think the routine feels really good, but I experience that I am becoming a little dry. Is there anything you think I should add to the routine for more moisture?1963 views- The user's roll: Lyko Creator. The comment was made 8 monthsHey Julia, That sounds like a really great idea to add the Hyaluronic serum, and it works super well with the Niacinamide serum. You can use Niacinamide first and then Hyaluronic. Good luck 🩷
