Since incorporating this serum into my skincare routine, I noticed a significant purging phase after about a week of use. After Influenster posted about it on Instagram, I discovered that many others experienced similar purging effects. I have dry/combination skin, and to manage the purging, I switc...

My Favorite Serum
The fact that this serum is under $30 and outperforms serums that are $100+ will never cease to amaze me. Not to mention the amount of product you receive is unreal. This serum does it all and then some. My skin looks and feels so much better within minutes after application. I will never stop repurchasing this product. It's truly incredible.
CosRx Peptide Booster
Nice formulation. Goes on smoothly, leaving a bright, clear skintone. Sinks into skin quickly leaving no tackiness. I really prefer this product compared to other peptide serums I have tried. For reference: I am fair and generally wear sunscreen over the top of any serums. I am easily sensitized, but not with this product. I will be repurchasing.
One of my staples
Going on 3 years of using this morning and night. My skin definitely improved drastically. My routine - led dr dennis gross mask, then this then moisturizer then spf and same at night minus spf and add retinol/ aha alternating nights. I am 35 and according to an app that was very accurate at guessing ages i appear 26-28. This is a huge part of my routine. This must be my 10th bottle. I was about to buy and wanted to post a review first since this is one of the products i find actually worth buying.
Great serum!
I received a deluxe sample of this and used it for a few weeks Love it ao much I bought the full size. It is so hydrating and makes my skin feel good. I love all the benefits and ingredients in one serum. It streamlines my routine. Definitely recommended this!
swear by this stuff
I originally received this as a birthday present from Ulta last year, and I adored this product so much that I bought a full size the moment my mini was empty. I'm an oily faced woman who will soon be 41, so during the day it's essential that whatever moisturizer I put on my face has to be very light or I'll end up an oil slick. because of this, for many years, I simply skipped moisturizer and went straight for my primer. now that I'm a little older and my face needs that moisturizer step to soften lines, this is absolutely perfect!
