    More like a booster for your other serums

    [This review was collected as part of a promotion.] It's more of a feel good product. Didn't see any change in my face. I used them as a toner before using my other products. Consistency is more like thick water. Packaging is fine, easy to use pump. I have normal to dry skin.

    Amazing! I have been using

    [This review was collected as part of a promotion.] Amazing! I have been using this in combination with the Snail 92 all in one cream. I live in a dry climate so it helps keep my skin moisturized without feeling greasy.

    I will definitely keep using this!

    [This review was collected as part of a promotion.] I was supposed to receive this product from Influenster, but when I got the box it did not contain the product. So I was confused and deleted the app for a while. But, I have since tried the product and it is fantastic. It really takes the age out of your facial/neck skin. I’ve purchased it twice so far, and despite it being a wonderful product it is actually pretty affordable. I will definitely be buying this again.

    Fine lines GONE

    [This review was collected as part of a promotion.] This skincare was amazing. I had purchased it before and was so happy when I received it. The texture is not too sticky or thick. It is the perfect consistency for skin rather your skin be dry or combination skin. My fine lines had went away within a couple of runs of recurrent use daily.

    Works Well!

    [This review was collected as part of a promotion.] I still use this product almost daily! I was worried about my skin getting too dry, even though I have combination skin. It works to provide a natural moisture layer that won’t leave any residue.

    Highly Recommend

    [This review was collected as part of a promotion.] Has a really lightweight, almost watery texture that absorbs quickly and doesn’t leave any sticky feeling behind. Most importantly, it didn’t irritate my skin or cause any breakouts. After using it consistently my skin is starting to feel smoother. It has not been an overnight transformation, but I have noticed that my skin is looking healthier and more even as time goes on. It also layers really well with the rest of my skincare, which I appreciate. If you have sensitive skin this is a solid option. It’s gentle, effective, and easy to incorporate into your routine.

    Love this product! My second

    [This review was collected as part of a promotion.] Love this product! My second of many more purchases to come. It helps even out my skin tone and provides just the right amount of moisture to keep my combination skin hydrated but not oily. Hope they add some more anti-acne ingredients in the future though, as my chin congestion hasn't changed and I've been using the product for 6 months now.

    Not Much Difference Seen

    [This review was collected as part of a promotion.] I was excited to try the 6 Peptide Skin Booster and had high expectations for it. While it did feel nice and cool on my skin, I didn't really see a difference in my skin texture or discoloration.
