I’ve never used such a great pore minimizer for this reasonable of a price. I love how smooth and clean it makes my face feel. I’ve been using it twice a day after cleansing my skin. Noticeable difference in visible pores and decrease in black heads on my nose and chin. Highly recommend!! Come on with this price, you have nothing to lose.

Serum does not work to reduce pore size

Size: 1.01 Fl Oz (Pack of 1)

While this serum does somewhat smooth skin it does absolutely nothing to reduce pore size which is primarily genetic and is resistant to most products. Not worth the money.

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.
