Decrease in black heads. Smoother skin!
Size: 1.01 Fl Oz (Pack of 1), Size: 1.01 Fl Oz (Pack of 1)
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.

Pleasantly surprised
I’m two jars in and love it. I do use Botox, retinol, a good face wash, wash moisturize twice daily, etc etc. I struggle with moisturizer because I’m prone to breakouts. Idk what it is about this one but my skin loves it. It feels refreshed and soft. Added bonus, my eyebrows and lashes have gotten longer and darker quick! Obviously we all respond differently to products but I’ll be keeping this in my rotation

A thick and rich cream that smooths on nicely!
So I jumped on the Korean skincare bandwagon and decided to purchase some of the DR MELAXIN Products to try! I read many good reviews and decided it was worth the money. This first product is the Dr Melaxin Calcium cemenrete calcium volume cream. It comes in a 1.76 ounce glass jar. On the label there is a lot of word descriptions so I will add a few: Ex volume firming, rebornic 10,000 ppm hydrolyzed elastin and collagen extract. I have photographed label for viewing. The directions indicate to "apply a small amount of cream onto your face especially around the under-eye area". I found the cream thick and rich and I used it in addition to another Dr Melaxin neck and face product so I concentrated on only neck and under eye area. It is neutral in scent and is very thick so it feels like it is absorbing nicely. I have been using it for about a month now and have definitely noticed some improvement in the neck area so i will continue to use and layer with other products. I do recommend this line as the ingredients seem effective so far!

Good product for face.
Great product. Works well with decreasing lines in face after half is used and with the serum. It does leave somewhat of a sticky (not grimy) texture which is uncomfortable if using at night.
