All in 1 serum

[This review was collected as part of a promotion.] This does not leave a film on your face like other ones do! I have a breakout on my cheek and this did not disappoint, not only put moisture back in my face it took all the puffy irritation and discoloration out!

Great hydration

[This review was collected as part of a promotion.] I used this whole bottle. It was great for my face and hands to produce supple skin ready for makeup or just for moisture. I would buy again. The texture is wonderful and the package is easy to use.

Holy grail staple for clear skin!

[This review was collected as part of a promotion.] This product is my holy girl strapless in my skincare routine! Not only is it affordable but you only need a bit after washing your face and I have seen wonders to my skin! As you can see, I have used nearly half the bottle and you only need one pump! I makes me feel clean and has cleared my skin concerns the best way possible. Give this product a try and you won't be let down!

I ran out of this

[This review was collected as part of a promotion.] I ran out of this and thought I’d just use the cleanser, snail musin, and spray mist cream to save money; however, adding this prior to the snail musin makes my skin glow. I am 51 and see a difference when using it. Less visible lines also.

Glow!

[This review was collected as part of a promotion.] Made my skin seriously glow! Such a huge bottle for the price too! My makeup layered great too because this is such a rich but thin consistency. Love it!

Overall, great product

[This review was collected as part of a promotion.] I tried this via influencer and have repurchased since as I feel like it did what it was supposed to. I find I would use this towards the end of my skin care routine to lock in products and moisture. I liked it a lot and would reccomend

Glassy skin and smaller pores

[This review was collected as part of a promotion.] This has been in my regular rotation since before anyone was ever talking about peptides. Makes my skin so glassy and soft and my pores smaller. I’m such a big fan.
