TIRTIRNiacinamide 20% Serum 30ml

The best product I have used. After 6 months I look 10 years younger!!!

Excelente product to care of your face skin. It works really good and it has all the components you need for a clear and glowing skin. Will recommend it

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 !!

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.

Tirtir products are amazing skin care products. Korean skincare is the best

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.

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.

Used this for a month morning and night. I haven't noticed any improvement. I wasn't expecting it to be a miracle, but I'm disappointed that I haven't seen any lightening.
