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...

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!

Bottom Line Yes, I would recommend to a friend

This caused me to break out and wasn't noticeably hydrating. Do not understand the hype.

Love it and have purchased it over and over

I LOVE this stuff! I use it as the first step in my skincare regimen after I wash. It absorbs quickly and you don't need a ton of it, so a bottle lasts quite a while. Great value for the money. It's easy to layer under other skincare and under SPF, so I use it morning and night. I am 41 and I've been using this on my face, neck, and the backs of my hands for over a year. During that time, I've noticed my skin looking brighter and more even. I keep repurchasing multiple bottles of this when it goes on sale, just so I don't run out.

Bottom Line Yes, I would recommend to a friend
