Must try!

[This review was collected as part of a promotion.] The bottle of the product is so nice, no problem dispensing. For the serum itself, it’s lightweight and feels cool on the skin. It’s really hydrating and not oily at all. My makeup applies great on top. It also has no strong scent.

Not For My Sensitive Skin

[This review was collected as part of a promotion.] I was very interested in trying this product because I’m looking for a serum that will help me achieve more plump skin and reduce the appearance of my forehead lines. My skin is extremely sensitive so unfortunately, the various botanical oils in this weren’t a good fit for me. There is an essential oil type scent to the product along with a vibrant pink color. The color was fun. I think the camphor in this was what I was smelling and possibly what caused the irritation/itching. I wish products with new skin technology would formulate for all skin types including for those that are more reactive. The serum was a bit tacky at first but dried down nicely. I wasn’t able to determine if this met the stated claims if plumping due to irritation. *I received this product for testing purpose in exchange for my review. My opinion is my own and based on my personal experience trying the product.

I used to LOVE this company and their products however I went cruelty free.

Lightweight, easy to layer daily skincare staple!

[This review was collected as part of a promotion.] Love this serum! Using in the morning and evening consistently, I have seen noticeable improvement in my overall skin hydration and plumpness. The gel-like formula is light and easily absorbed, and layers well with other products as well as makeup. Will definitely be refilling!

Great product

[This review was collected as part of a promotion.] I have been loving this serum. It leaves my skin filling soft, hydrated, and looking more plum and refreshed. Definitely a great addition to my skin care routine.

Extremely Hydrating!!

[This review was collected as part of a promotion.] My skin feels noticeably more hydrated, smooth, and plump after using it. I’ve also noticed that my fine lines look softer and less noticeable. It leaves my skin feeling really hydrated without being heavy or sticky.

Skin is glowing!

[This review was collected as part of a promotion.] I love how this feels on my skin. My skin felt so hydrated and plump after using it. I like that it doesn’t have a strong scent and that it has a cooling feeling when applied. I have pro acne skin and so far this product hasn’t made me break out, so that’s a win! I will definitely keep using this after seeing how glowy my skin looks even without makeup.
