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.

Really enjoying this product - Big confidence boost
Size: 2.02 Fl Oz (Pack of 1)
I was a little skeptical at first.. I saw a different brand of cyperusrotundus oil circulating on tik tok and was super interested in a natural remedy to treat facial hair. I did some digging and tested this one. I’ve been using it for about a month and I have to say I notice such a big difference in the texture of the skin on my face. I’ve seen some significant improvement in facial hair growth overall!! Im hoping with prolonged use, it will make an even bigger impact - but so far I am very pleased! I use it 2x a day and I’ve been feeling more confident! Would definitely suggest trying this!
