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.

The 6 peptide skin booster

[This review was collected as part of a promotion.] The 6 peptide skin booster serum is amazing 👏. It hydrates and illuminates the skin, giving it a plump and radiant look. My skin has improved a whole lot from what it used to be.

Great feel on skin!

[This review was collected as part of a promotion.] Love how light it feels! No harsh smell and did help my skin a lot! A great amount for the price, and helped my redness a lot! Easy to store, the cap just falls off quite easily sometimes

I've noticed my skin is

[This review was collected as part of a promotion.] I've noticed my skin is more hydrated. I use before the alpha arbutin serum and I like the effect. I haven't used it long enough to notice any additional benefits towards helping my hyperpigmentation, but my skin feels much better with less breakouts.

An effective skincare product that is comfortable for everyday use.

[This review was collected as part of a promotion.] This skin booster serum applies smoothly and absorbs well with no residue and hardly any stickiness. It's easy to apply under skincare and makeup and left my skin with a moisturized glow. It also did not irritate my sensitive skin.

I purchased these product due

[This review was collected as part of a promotion.] I purchased these product due to all the hype, but did not notice a significant improvement to my skin. I applied this product nightly prior to the snail mucin essence and moisturizer which I have used for years (and enjoyed), but I did not feel that this product added value to my skincare regiment considering the price. It did't make my skin worse, but I will not be repurchasing. Photo shows that I used about 1/3 of this bottle prior to determining my review.
