Unbeatable Value for the Price!!
I’m so impressed with the packaging of this kit! It came with the cutest little bag, perfect for the pool or beach. The product sizes are much larger than I expected, and the mitt is excellent quality. I haven’t tried everything yet, but I’m really excited to. For the price, this kit is a fantastic value considering how much you get! One small note: the “Gimme the Glow Down” spray could’ve been filled a bit more (see photo). I did test a quick spritz on my face, it felt refreshing, but did have that classic self-tanner scent and left a slight sticky residue. Nothing major, though. I’ll update once I see the full results on other products! UPDATE: I LOVE THESE PRODUCTS! The tan is so even and gives a great glow to my skin. I wash my face twice a day so I use the glow down spray to refresh the tan. I used this self tanner for my engagement photos and it looked like I just came from the beach! (See last photo)

Dark coloring but very streaky and stains easily.
Color: Medium Glow
While it does darken the skin one has to be VERY careful when putting it on. It does stain and it is very streaky and it does stink after wearing it a while so the smell is rather yucky and they advertise that it is not. I had streaks everywhere and unevenness so I ended up ordering a glove to apply it with hoping that will do a better job. I have not tried it yet but am probably going to return one of the 2 bottles I received and hope for a partial refund.

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.
