COSRX - The Niacinamide 15 Serum - 20ml

I love Niacinamide. It's a proven ingredient in my skincare routine, so I was looking for a serum booster to add to whatever step I wanted. This one is the highest I found that works. It's a watery consistency that mixes well with toners and serums without disturbing them. I like to use it in my nighttime routine, I feel like it really softens my skin overnight and the zinc in it certainly helps clear up acne overnight. To me it's a far better formula than other Western brands that use the same Niacinamide+Zinc pairing and have the lab bottle feel (*hint hint*).

I received this product for free from CosRx and Influenster in exchange for my honest review. I think this is a good every day serum! I’m a huge fan of niacinamide in my routine and have been for years, as there are spots on my face that are an absolute oil slick if left to their own devices and I have massive pores in those areas as well. This serum is definitely in the top 5 niacinamide serums that I have used. I can definitely tell the difference in the oil production throughout the day on my skin on the days that I use this and on the days that I may miss this step in my routine. Even though I have not changed my moisturizer at all, I have found that my skin feels more hydrated since adding this serum into my routine.

Even though I have not changed my moisturizer at all, I have found that my skin feels more hydrated since adding this serum into my routine. I did some research and learned that was a benefit of niacinamide that I was unaware of (it helps create a lipid barrier to help retain moisture). This isn’t heavily scented, I could not really discern one which is a plus for me. And it absorbs into the skin quickly without leaving that tacky feeling. With its reasonable price point, I would say this is definitely worth purchasing if you are looking for a niacinamide serum or want to try one!

to gently exfoliate skin and fade hyperpigmentation, zinc PCA to balance skin’s oil-water levels and allantoin to promote collagen production.Even in my thirties, I still have moments of mild acne breakouts which can be frustrating. I do tend to have more sensitive skin which also leads to breakouts, and it can take a bit longer to heal and resolve completely. I loved using this niacinamide 15 product, especially in conjunction with the Cosrx Vitamin C serum. The combination together was so effective for my skin! My face was glowing and my skin felt so hydrated and smooth. I have been applying these to my skin at night for the past month and Im truly amazed at the transformation of my skin texture and appearance. I do not use these in my morning routine.

I had no sunburn, dryness or congestion issues whilst using these. Any acne I experience was minimal and resolved quicker than normal. I appreciated that a few drops go a long way. I like the bottles and the application syringe, they were easy to use. as I get to the bottom of the bottles it will be interesting to see if there are any issues getting the last drops of product out.
