Background

Regulatory factor (IRF) family - IRF-3 is the key transcriptional regulator of type I interferon (IFN)-dependent immune responses which plays a critical role in the innate immune response against DNA and RNA viruses. IRF3 regulates the transcription of type I IFN genes (IFN-alpha and IFN-beta) and IFN-stimulated genes (ISG) by binding to an interferon-stimulated response element (ISRE) in their promoters. It acts as a more potent activator of the IFN-beta (IFNB) gene than the IFN-alpha (IFNA) gene and plays a critical role in both the early and late phases of the IFNA/B gene induction. IRF3found in an inactive form in the cytoplasm of uninfected cells and following viral infection, double-stranded RNA (dsRNA), or toll-like receptor (TLR) signaling, is phosphorylated by IKBKE and TBK1 kinases. This induces a conformational change, leading to its dimerization and nuclear localization and association with CREB binding protein (CREBBP) to form dsRNA-activated factor 1 (DRAF1), a complex which activates the transcription of the type I IFN and ISG genes. It can activate distinct gene expression programs in macrophages and can induce significant apoptosis in primary macrophages.

Good and Hydrated
Size: 1.01 Fl Oz (Pack of 1)
It’s very good and hydrates very well. Not a fast or much improvement on pores. But very good to hydrate your skin.

Just buy it
Size: 3.38 Fl Oz (Pack of 1)
I am not even sure I want to do this review because this might mean this product gets sold out. But I wont gate-keep. Get it. This has changed the game with my skin care. I use it twice a day and let me tell you, the compliments I get are incredible. It is not greasy at all, absorps quickly, super light weight and does not irritate my skin. My skin is glass smooth. I have bought this for everyone in my life. Male and Female. I use it, let it dry then add moisturizer or sunscreen.

Works well with others!
Size: 2.03 Fl Oz (Pack of 1)
Initially and by itself, I really didn’t see any changes to my face that made me confident with this product. But now that I have a skin routine, I think it works well! Now I like it and I see changes. But alone or with few products, I’m not sure how effective it is!

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.
