Overview:

99-04 Mustang Long Tube 4.6L Raw 409

    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.

    Helped Tighten My Skin & Minimize Pores
    Color: Cyano Pink Spicule, Color: Cyano Pink Spicule
    I’ve loved the Dr. Melaxin Cyano Pink Spicule Serum! The bottle is small, but it lasted me around 6 months since I only use one pump every other night. When I first started using it, I noticed a tingling sensation, but over time my skin adjusted and I barely notice it now. I’ve definitely seen my pores appear smaller and my skin feels tighter and smoother after using it.

    Great for pore reduction
    Color: Cyano Pink Spicule
    This product works great!! it almost feels like an exfoliator. It reduced the pours on my nose, which were very big and now you can barely see them. I would recommend this product if you have large pores also make skin look firmer and smoother more for a night cream though.
