This is the one …
I am in love with this serum! I do not notice any scent and it hasn’t caused any irritation on my otherwise sensitive skin. This is my second purchase, the first bottle lasted about 4-months. It has been incredibly effective, for me, as there is a noticeable change in my hyperpigmentation/sunspots so I will continue using it. The texture of my skin also seems smoother and it does provide a beautiful glow without being greasy. I suffer from incredibly dry skin and I feel this has helped with that, as well. I have tried many, many products to target my dark spots and this is, by far, my favorite. I always it morning and night in my regular skincare routine. The only “con” I can address is the fact the dropper doesn’t catch the bottom of the bottle, so I just remove the dropper and tap some out on my fingers – this, I believe, is why it’s lasted as long as it has. I don’t use much, at all – 3-drops with each application. I am 52, spent years in the sun without sunscreen or otherwise daily skincare regime and this has really upped my game when it comes to brightening and smoothing. Not only is it repairing, it’s also preventative .. please always remember to use sunscreen with it. Love it.

High strength niacinamide – but also has retinol
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.

This product works so well I’m 40 years old and just started getting fine lines after using this product for a couple of weeks my skin looks so youthful

Nothing noticeable yet
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.

Disappointing
This serum is supposed to minimize large pores. I have been using this serum daily for a month and the large pores I was hoping to reduce still look exactly the same. It has not helped my skin texture at all, leaving me to believe it is not an effective formula for what it is advertised as. Also, the outside of the box says to thoroughly read the enclosed materials with the use and warnings. However, there was no little paper in the box. WHAT ARE THE WARNINGS? I looked up this brand on their website and everything directs you to Amazon. There is no more information for the product available online from what I could tell.

Creo que su relación calidad precio no es buena. Hay otros productos que me han gustado más con niacinamida. Lo he probado por varios meses y no me ha gustado su resultado
