      Amazing!
      Color: Cyano Pink Spicule
      This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.

      Brightens, doesn't firm
      Color: Cyano Pink Spicule
      I've been using this for about a month now, every night on my face and neck, hoping to reduce the appearance of wrinkles and tighten some of my skin in that area that seems to be losing elasticity. On my neck, I've honestly noticed no real difference in 4 weeks of continued, consistent daily use. The skin on my face does seem brighter and somewhat less textured than before, but I haven't noticed any change in the issues I was hoping this would resolve, based on the claims and how it was marketed. So... not a bad addition to my skincare, but not the solution I was looking for. Some have expressed concerns about it tingling or stinging... You can feel something when you apply it, it's almost like the feeling of static electricity, but it's very mild. I wouldn't let that stop you from giving it a try if you were concerned about it. It didn't cause my sensitive skin any breakouts or redness (although I was applying it at night before bed, so perhaps any redness was calmed overnight). I'm going to go ahead and finish the bottle, but based on these results, I probably won't repurchase.

      Love it get it girl!
      love this collagen balm stick—it really feels like a little “magic wand” for my skin! It’s so easy to apply and super convenient to use on the go for the eyes, neck, and face. The texture glides on smoothly without feeling greasy, and it gives an instant boost of hydration and a nice glow. I like that it helps my skin feel more plump and refreshed, especially on dry or tired areas. It’s become a quick step in my routine when I need a fast touch-up or extra moisture. Overall, very impressed with how effective and easy it is to use! ✨

      Surprised!
      I was really hesitant to get this product because of the very mixed reviews but I decided to give it a try. I was so completely surprised by this and its effectiveness and appearance. While I haven’t used it long enough to know if it has any effect on fine lines, the under eye effect is truly magical. I’ve yet to find any product that makes my bags go away, but I just put a light layer of this on and my bags go away in 10 minutes and I look like I slept twelve hours and aged in reverse. It is definitely a greasy product so if you are prone to oily skin, I’d say this may not be the product for you. For me, I put a light layer on under my eyes, my smile lines, and forehead. For me, it absorbs quite well and leaves my skin looking very shiny and glowy which I love. I have not had any issues with the texture of it, or had it leave any residue but I’m using quite a thin layer, which I think is what is intended. 10/10 would but again.
