Absolutely Love!!
Love it .. it's as delicious on the skin as salmon is to eat .. feels like a healthy fat for your skin ! Pleasantly surprised Blind buy , incredible product for the price , very quality .. goes on greasy initially like an oil ( In a good way ! ) .. but absorbs fast feels light , like a light watery grease , so much fun to apply , feels so good youll want to bathe in it .. I find myself applying to elbows and hands .. my skin Does have a hydrated glow throughout the day but stays light ,, doesn't get heavy, doesn't feel like I'm wearing anything .. works better as a primer too light to really be a moisturizer

not medical‑grade PDRN
it is not medical‑grade PDRN, the brand is small and new, and the product is more hydrating/firming than the dramatic “skin repair” claims suggest. It is not dangerous, but it is also not the miracle it markets itself to be. bHydrates deeply, , Makes skin look plumper and bouncier, • Helps dryness and dullness, Gives a temporary “glass skin” glow

Glow & texture focus
Really good serum! Helps calm redness and dryness, especially after microneedling. Lightweight, non-sticky, and absorbs fast. My skin feels softer and more balanced since I started using it. Worth trying if you want soothing and healing-focused skincare.

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!
