      More than expected
      Color: Cyano Pink Spicule
      Love, love and recommended to friends. Leaves my skin feeling and looking great. At 69 I don't expect miracles but can definitely see an improvement in texture, glow and line minimizing. I'm hooked and will never be without!

      Micro-needling effect!
      Color: Cyano Pink Spicule
      Love how you can feel the micro-needling effect. I use this is my first application after toning and follow up with my serum and moisturizing routine. I do believe it gives my face a plump feeling, especially after gua sha. Will continue to use in my daily!

      Helps my moisturizer absorb better
      Color: Cyano Pink Spicule
      I’m not quite sure if the product is fully working the way it is supposed to but I do like that when I use this and the apply moisturizer, it absorbs into my skin better and leaves my skin smoother and a lot less greasy. It’s easy to throw in my travel bag because of the size and you really only just need a little for each use so it goes a long way got the cost.

      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.
