Background

Interferon lambda 2 (IFN-λ2), also known as IL-28A, is a member of the type III interferon family, which also includes IFN-λ1 and IFN-λ3. IFN-λ2 plays a crucial role in the innate immune response to viral infections and has been shown to exhibit antiviral activity against a variety of viruses, including hepatitis C virus, influenza virus, and others. It signals through the IFN-λ receptor complex, leading to the activation of JAK-STAT signaling pathways and the induction of interferon-stimulated genes (ISGs) that contribute to the antiviral defense mechanisms. IFN-λ2 is primarily produced by immune cells, such as dendritic cells and macrophages, in response to viral stimuli and functions as a key mediator of the host's defense against viral pathogens.

Perfect combo
Color: peach+urea
The perfect duo for soft, pretty feet. They are easy to apply, feel really good on the skin and actually work. The you're cream helps break down calluses and the cracked heel stick softens and moisturizes. It also smells nice!

Best Foot Cream I’ve Ever Used!
Item Package Quantity: 1
This is honestly the best foot cream I’ve ever used! My feet are incredibly smooth, and my heels look like they’ve never been cracked. I’ve struggled with dry heels before, and this made such a noticeable difference. Highly recommend!

Works great!! I have had dry, cracked heals for years because I don't wear shoes around the house. Even my manicurist says my heals look great!

Miracle
Item Package Quantity: 1
I wish I had before and after photos, my feet are in much better shape after using this. I still need to work on them more but I ran out pretty quickly but my feet were dry af. I used to “shave” my feet once a month this is the power of foot filing in a stick. I will never foot file again. I need to find a way to make it last longer but I think I will not need as much now that my feet are in better shape. Iykyk, get this. It’s greasy as all hell but it’s easy to apply and you can do it over a towel and then put socks on immediately before bed. I wish it was a bigger stick but it is not too pricy so it’s worth it.
