    Question about use

    Can this be used by pregnant/breastfeeding women? And can it be combined with lumene nordic c booster?

      Hey there 💕 Cosrx The Niacinamide 15 Serum contains niacinamide, which is a mild and effective ingredient known to help even out skin tone and strengthen the skin barrier. It is generally considered safe for both pregnant and breastfeeding individuals, but as always, we recommend consulting your doctor or a dermatologist to be completely sure, especially if you have specific skincare needs during pregnancy or breastfeeding. When it comes to combining this serum with Lumene Nordic C Booster, it is possible, but be aware that vitamin C and niacinamide can sometimes react with each other, although recent research suggests they can be used together without issues. For best results, you can test the products at different times of the day (for example, vitamin C in the morning and niacinamide in the evening) to see how your skin reacts. Also, always remember to use sunscreen in the morning when using products with vitamin C! ☀️🧴 Wishing you a great day ahead!

    Fridge or not?

    Hi! I just wanted to ask if this is good to keep in the fridge or if it can be stored normally in the bathroom cabinet? Thanks in advance!

    Torriden \u002B Cosrx?

    Can I combine this with Torriden Toner Pad and Balanceful Cream? I usually use these during the day with the serum from the same line. In the evening, I use Cosmica renewing face oil and Cosrx snail mucin cream. I tend to get pimples and bumps, and I have a few scars and dark spots that won't go away.

      Hi there Emely ✨ Yes, these can be combined, I'm attaching a suggestion for a skincare routine 🌼 Morning: Cleanser: Gentle cleanser (e.g. CeraVe Hydrating Cleanser). Toner: Torriden Toner Pad (moisturizing). Serum: Cosrx Niacinamide 15 Serum (every other day if irritation occurs). Moisturizer: Torriden Balanceful Cream. Sunscreen: SPF 50 (e.g. La Roche-Posay or COSRX Aloe Soothing). Evening: Cleanser: Double cleanse (oil cleanser + gel cleanser). Exfoliation: 1-2 times a week (e.g. The Ordinary Glycolic Acid). Serum: Cosmica Renewing Face Oil or retinol on some evenings. Moisturizer: Cosrx Snail Mucin Cream. Tips: Exfoliate 1-2 times a week for even skin texture. Vitamin C during the day for dark spots (e.g. Cosrx Vitamin C 23). Retinol in the evening can help with scars and bumps. Remember SPF every day to protect against dark spots. Wishing you a great day ahead!✨

    Combine

    Can you combine this with dr. althea 345 relief cream? Looks like the cream also contains niacinamide. And can you combine this with the vit c serum from cosrx? Or should you use one in the morning and the other in the evening?

      Hi Veronika! It should be totally fine to use this serum together with the cream 🥰 Since I don't know enough about your skin type and condition, I recommend starting by keeping the serums in separate routines. Use vitamin C serum in the morning, and niacinamide serum in the evening ✨ Wishing you a nice day!

    Cosrx niacinamide

    Can this be used with azelaic acid or would this alone help treat mild periorificial dermatitis (a rash around mouth)?

      Hello Kim, Thank you for contacting us! 🥰 I would recommend focusing on soothing and hydrating products for the issue you described. For example, Laponie's Calming Serum could be a great choice! 'It’s excellent for managing symptoms of rosacea and periorificial dermatitis (POD) and is a gentle option for hormonal breakouts.' lyko.com/fi/laponie-of-scandinavia/laponie-of-scandinavia-calming-serum-20-ml If you’d like to pair azelaic acid with another serum, I would recommend hyaluronic acid! 💦 You can also fill out our free skin test here to get more personalized recommendations: lyko.com/fi/beauty-scan/ihotesti Have a great week! 🌞

    Best

    I have used up the first bottle and have ordered a new one. I think it works very well on my skin. I use it in my evening routine together with their retinol.

    Combine

    Hi! Is it effective to combine this product with cosrx acne care products, or does it become too much product mixed together, and if so, which ones should be prioritized to get rid of acne as well as possible?

    Didn’t notice a difference?

    This lasted very short… didn’t notice any difference, but probably needs to be used longer. It is very good for the skin though :)

      Hey hey Malin This serum is very effective for reducing acne scars, but it's hard to say in advance how much it will reduce yours and if they will completely disappear ❤️ But considering all the incredibly positive reviews this niacinamide serum has received, I think you should give it a try Good luck and take care of yourself! 🌸
