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...

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!
I have noticed an improvement in my skin tone.
I first received a sample size of this product for my birthday last year, and was impressed in the change to my skin with minimal use. It feels smoother and healthier, and there is a slight fading of my very significant dark spots. Thank you for the original sample!
Holy Grail
Whatever is in this stuff, it is like face crack. Meaning it is addicting. I bought this w very low expectations. And it was on sale for like $17. No lie, this is the best product in my face product arsenal and I have some pricy products. No offense to ordinary, but this is everything it claims to be, or at least for my skin. You wear it under whatever other face products you use, morning, night, whenever. I use primarily at night and noticed more supple looking skin in the morning. And I am exhausted, coming off a few months postpartum. This has been helping me fight the battles known as nightfeedings and sleep deprevation. Yes, I still look tired to a degree, BUT quality of skin is top tier. Get it, worth it. Love it.
I've finished so many bottles of this!
I've finished so many bottles of this peptide serum that I've literally lost count! This is a great, versatile formula, and I've been using it for the past 3 years. I have combination to oily skin and so many products seem too heavy for my skin and make it greasy, or they don't absorb at all. This serum is super lightweight - the consistency is almost like water. My skin drinks it up! It has no funky smells, it's not irritating at all, it plays well with other products, and it's quite affordable. My skin looks a lot more stable, healthier, and refreshed since I incorporated it into my routine. It's a keeper!
