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...

Pleasantly surprised!
I've been using this for about a month now and I'm so sad I didn't buy this sooner! By far one of my favorite staples in my skincare routine and I'm a very cystic acne-prone sensitive skin girlie. when I initially started using this, I thought the texture was quite "watery" and I didn't think it would actually hydrate my skin, but I was VERY wrong. Do not let the texture fool you. I use this right after cleansing my skin before I put on my toner, and then follow up with my serums and moisturizer. My skin has never been softer and I definitely think it helped with my makeup not looking cakey or dry. 10/10 highly recommend.
Irritated My Skin
Made my face itchy & I had random red spots in various places on my face after using. I used the gel cleanser, mucin power essence and this immediately after for 5 days straight and experienced the same reaction each day. Not using this brand again
Really good product!
I was given a travel size awhile back and just finished it, let me say my skin has never been clearer! I have oily acne prone skin which has gotten more sensitive over the years (I am over 20). Even though this isn't really its intended purpose I use it similarly to a moisturizer for my night routine, the moisturizers I was using just felt too heavy for me. It has been working for the past two months now so definitely recommend giving it a try!
I will never stop buying this product.
This peptide serum is the ONLY thing that keeps my skin hydrated like actually hydrated. Not just a product that sits on top of your skin and doesn't absorb, this does the work and then some. My skin looks like glass and just feels better with it.

Didn't work for my skin
I know skin care is super personal but i had a nad reaction to this, was fine for a few days but then i started breaking out with tiny little bumps :( so sad had to return
