COSRX Niacinamide 15%, Peptide Booster Serum Set, Pore Care & Hydration

The booster set is great for restoring my color, and it is quite gentle on the skin. It works well with my sensitive skin.

The 6 Peptide Booster has been a staple in my skincare routine for well over a year now. Plenty of other products have been rotated in and out, but this one you’ll have to pry from my cold, dead hands. I initially bought this set because of the 6 Peptide Booster, of course. Since COSRX is a brand I trust, I figured I’d give the niacinamide serum a try as well. It feels great going on, and my skin feels smooth and moisturized afterward, but I haven’t noticed a huge difference compared to the other niacinamide serum I use. Their labeled concentrations differ by only 2%, and they seem to have about the same efficacy. The real value here is the bundle itself. I can pay about the same price for a single niacinamide serum elsewhere, or I can get this one from a brand I already trust, along with the Peptide Booster. Don’t get me wrong—not noticing a huge difference doesn’t mean it isn’t working. If I stop using either serum (or forget to pack one for a trip), I definitely notice the difference. Together, they really do help reduce the appearance of my cavernous pores. I’ve even been told I’m glowing, though I’m not entirely sure whether that’s this skincare routine or perimenopause…

This makes your skin beautiful, Highly recommended.

The Niacinamide got rid of my nose piercing bump quicker than anything else i tried. For almost a year i had the bump and it would get bigger or smaller but not fully go away. I started using the niacinamide and i swear it was gone in a week. My pores are less apparent and my skin overall is smoother when using both of these products. I swear by the niacinamide though.

tried this brand on a whim, trying to find clean, cheap, k-beauty facial products and this was the winner. after using the peptide booster and essence and niacinamide for about 3-4 weeks now day and night i am completely sold. I have acne prone and combination skin, oily t-zone, drier on the cheek area, and sensitive around the nose, these products have not made me break out at all and ive even noticed significantly less breakouts. my red marks seem to be slowly fading too...i now use their other products as well and get a nice "glass skin" effect after using. My favorite part ,though, is the poor shrinkage this stuff is capable of! my only slightly downside of this, is that, in my opinion this stuff can be slightly drying, but as long as you pair it with a nice moisturizer your in the clear

Great quality products for the price! The peptide serum tightens skin and the Niacinamide helps tackle large pores. There is no smell and the product soaks into the skin nicely.

My older skin was SUPER dry and had been for a couple of years and my dermatologist was no help! I had heard (online) that Niacinamide is really good for all skin types so I tried this. OMG what a HUGE difference using this in conjunction with La Roche-Posay Lipikar AP+ Triple Repair Moisturizing Cream which I was already using. It took a week or two to see the results, but it works great! The two of these together did away with my super dry skin, thank God! You don't get a lot in the little bottle, but it works so well, it's worth it!

So I have tried lots of face creams, lotions, serums over the years. I am 42 and noticed my pores are large, and some lines on my forehead. I love my No. 7 products for basic face moisturizer. But it was not doing what I needed it to do. I came across this product after researching a lot! I would say within 2 weeks I noticed a huge difference immediately! My pores on my nose can’t even see anymore. My face looks really nice, feels great! There was a little burn when I used it the first 2-3 times, but not anymore. Probably because my pores are much smaller. I love this stuff, the best I have ever used. I am actually going to buy some for Christmas gifts. I also use this two times a day after I was my face. The only thing I wish the bottle would list the ingredients and it shows nothing. I would love to know what is in it, just to compare why this is the only stuff out of dozens of other products that actually work. Also, the price is very affordable. They will have it on sale too!

I’m so happy with this set. It even brought back a healthy colour to my face and my skin feels so smooth.

Ideal pour ma petite routine du soir 👍👍👍

Kann das Set jedem wärmsten empfehlen, der wie ich große Poren im Gesicht hat. Nach 3 wöchiger, abendlichen Anwendung im Gesicht bemerke ich bereits eine sichtbare Verbesserung an meinen Nasenflügeln. Abends verwende ich nach meiner Gesichtsreinigung Niacinamide 15% Serum und jeden 3. Tag Feuchtigkeitscreme hinterher. Bei meinen Pigmentflecken hat sich bis jetzt leider noch nichts getan. Bin Mitte 40. In der Früh trage ich den Peptide Booster auf gefolgt von LSF 50 (um weiteren Pigmentflecken bestmöglich vorzubeugen)
