Background

MARCO (macrophage receptor with collagenous structure), also known as SCARA2, is an 80 kDa type II transmembrane glycoprotein that belongs to the class A scavenger receptor family. MARCO is constitutively expressed on the surface of splenic and lymph node macrophages. Its expression is induced on Kupffer cells and alveolar macrophages by microbial infection, chemical irritants, and Th1 polarizing factors. MARCO binds LPS, lipoteichoic acid, and other determinants on Gram positive and negative bacteria. It also binds modified LDL, CpG oligonucleotides, UGRP1, silica, and TiO2. MARCO is required for the organization of the splenic marginal zone and the interaction of local macrophages and B cells.

A rich moisturizer that doesn’t feel heavy!
Size: 13.5 Ounce (Pack of 1)
I bought this because the skin on my face is very reactive and has also been very dry and I wanted to try something that was a little more rich than the moisturizer I was using. I liked that this is for face and body so it comes in a bigger size than typical face moisturizers come in. I have been using it for about a week and have noticed a reduction in flakiness and my sensitive skin does not get irritated by it. It absorbs really well and doesn’t feel heavy or make my skin feel sticky. I definitely feel it is worth the price since you get so much in the bottle and it will last a very long time!

The best eczema cream I’ve used !!!
Size: 6.76 Ounce (Pack of 1)
I will give 10 stars if it were available!! Used most of the eczema creams out there, including prescribed ointments, but given the fact you can’t avoid using water on your hands throughout the day, the eczema was only getting worse for the past couple of months! I am glad I didn’t give up and found this cream!!! The second I put this cream on my hands, it immediately moisturized the itching and flaking skin without drying or being greasy unlike other creams I’ve used before. It’s very calming, soothing, and deeply moisturizing! So I had to write this review for those who are suffering the similar symptoms. This may help you as much as it is helping me as I speak!

Seems to work for damaged barrier (accidental damage as well as eczema and rosacea).
Size: 6.76 Ounce (Pack of 1)
SO I am currently tryign to repair a damaged skin barrier. I have both rosacea and eczema so it's nearly impossible to find a product that makes both conditions happy. I started out using the cream version of this but my face always felt dry with it. I decided to try this since a balm usually helps keep in moisture much better. I am only using a gentle cleanser and this, planning on adding in a toner at some point. At first I thought I was sent the cream again because this comes out like their cream version but as you rub it to spread, you can tell it has a thicker feel to it. It spreads easily and doesn't tug at my skin. Seems to sink in pretty quickly but it does leave a sticky film until it completely absorbs. I can feel my eyelids stick while waiting. Not sure how long it takes to fully absorb because once it does on my eyelids, I forget. But the stickiness does go away and leaves a soft texture behind. I do find some itching in places I normally get when my skin dislikes an ingredient. But I'm not sure if it's my normal or current damaged barrier. It helps with the dry feeling and I would say I only feel a slight tightness. But so far, the best moisturizer I have used. And I love that there is NO NIACINAMIDE, NO HYALURONIC ACID, no oat, no shea butter, and no cica/centella asiatica. These ingredients wreak havoc on my skin and everybody is adding this to everything. It's been so hard to find a moisturizer.

Works quickly to calm itch
Size: 6.76 Ounce (Pack of 1)
I had an itchy outbreak on the back of my hand the day this product arrived. Perfect timing. Applied Avene and within a short time the itch calmed almost 100%. Slept through the night and this morning, the red rash is about 95% healed. So glad I bought this. Just another old age issue to deal with.
