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…

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.

Arrived quickly, well packaged. Haven’t used the products for long yet, but so far so good. No negative reactions. The peptide serum stings on open skin but once the small acne spots healed, it feels nice on the skin. No super obvious smell, no artificial coloring. Happy so far.
