TIRTIR Niacinamide 20% Serum 30ml

I ordered this on a Black Friday deal but I hesitated using it as I was a little worried about the strength being 20% -- but I was almost out of my Cosrx 15% niacinamide and wanted to try TirTir's. I have their milk ampoule and vitamin c, which I really love.I apply this after cleansing and my vitamin c, or sometimes just the niacinamide alone. I was very happy that this higher strength did not irritate or redden my type 1 rosacea-prone skin.Just know that niacinamide serums can be a little sticky or tacky but give it time to absorb. I cleanse, tone, and then wait a little while before applying my vitamin c, then I wait again before I apply niacinamide, then another wait before my serum(s). How long you wait is up to you but I give anywhere from 5 to 15 minutes between these first steps. I think even just a minute or two would be fine - to give the serums time to absorb before applying another one.TirTir has some beautiful skincare products and my skin loves the formulas - I also love Beauty of Joseon, Cosrx, and Gangnam Glow.Niacinamide in the correct formula and strength, as this one is, gives my face a really nice glow.The only thing I wish it didn't have is the retinol - that would have me not reordering this and going for the CosRx instead for my reorder of niacinamide. But if you like blends like this, this is a very nice brand to try.

If you want a product that will give you that glow, help with wrinkles, reduce pores, then TirTir Korean skin care line is top notch. Bye it, try it, you won't regret it.

Love this brand. I went to Seoul found the store and went nuts!!! All products are outstanding. Makes you skin feel so moisturized and fresh.

I have used TirTir Rice Tone on my face & neckr for a year now and my skin looks better than ever ! I actually have recieved compliments on my skin. I buy TirTir Rice Toner from Amazon because of the price. Watch for the price breaks !!

Very happy I tried this serum. Makes your skin feel great. I purchased this serum and the milk toner. Will definitely purchase again.

I've only been using this for a few weeks now and although nothing is noticeable yet, I am in a rhythm using it and it doesn't smell horrible of feel weird. I'm a guy and these things matter. I'm hoping that with continued use, it'll help with my oily forehead.

I have a oily T- Zone in the Summer and a Dry T- Zone in the winter. I am trying to target my fine lines and wrinkles.I apply this at night before bed! Is it a little tacky, YEP, does it bother me, nope lol, it does go away. Does it do everything it claims, ABSOLUTELY. It has no scent. My skin is bright & firmer. I use tirtir ceramic cream for moisturizing after this! Great Quality.. Love the bottle and the dropper for a thin product like this! I will be repurchasing if it's still the same price!

I’m that product irritated my skin
