Name: Silk Fibroin Methacryloyl

Product Overview

Silk Fibroin (SF) is a polymer polypeptide consisting of multiple amino acids derived from the degumming process of silkworm silk.SF molecule consists of a hydrophobic peptide chain (H chain) and a hydrophilic peptide chain (L chain).The special amino acid sequence of the H chain and the L chain enables it to form a variety of protein secondary conformations. It is possible to control the secondary structure of filipin proteins to effectively control various properties of filipin materials, including the preparation of high-strength and high-orientation materials. Because of its biocompatibility, biodegradability, high tensile strength, etc., it has been used in various biomedical fields, including wound dressings, artificial blood vessels, cell culture, etc., and it has been certified by the U.S. Food and Drug Administration (FDA), which makes it a very promising biomaterial.

Silk proteins cannot be dissolved in water due to their own high degree of crystallinity, and this hydrophobic property makes it difficult to obtain a homogeneous structure when compounded with hydrophilic systems such as hydrogels. In order to improve the dispersibility of filipin, filipin solutions are often obtained by salt dissolution and dialysis, followed by the preparation of the corresponding composite materials. The preparation process of silk protein solution is cumbersome, with poor stability and easy spontaneous gelation, which limits its biological applications.

In order to meet different application requirements, XFNANO team selects high-quality mulberry cocoons, and through a series of processes, we have obtained the silk protein products with good water solubility, stability, and material extensibility, which can be quickly dissolved in water, and can be used in conjunction with a variety of types of hydrogels, such as GelMA, HAMA and so on, in order to adapt to the needs of different application fields.

It’s just OK
Size: 1.1 Fl Oz (Pack of 1), Size: 1.1 Fl Oz (Pack of 1)
It’s a perfect match to my skin tone although the coverage is so light that I’m sure it doesn’t matter too much. It takes a minute to blend in like most other sunscreens. It’s not my favorite but it’s not the worst. I have oily acne prone skin and after using AI to research ingredients in SPF I went with this one bc it was less likely to break me out compared to others. It is pretty greasy and makes my face look more oily than dewy so I just use Paula’s choice shine stopper on my t zone and that handles that issue so that I don’t have to just throw this out. $20 for 1 oz is pretty steep I’d rather just get the Australian gold that has a more matte finish and is easier to blend

Good finish; but slow dry down, runny, stains clothes.
Size: 1.1 Fl Oz (Pack of 1)
I use this in the lightest shade. It's runny, and it takes about 15 minutes to dry down. It also transfers and sometimes stains my clothes if I'm not careful. The stains do come out, but meanwhile I'm walking around with a dirty shirt. So WHY have I purchased it repeatedly? Once it does dry down, the finish is beautiful. It's radiant, but not overly glowy. On my normal (not oily or dry) skin, I don't need a moisturizer with it. Most importantly, the color is the perfect shade for me. I get compliments on how good I look every time I wear it. I wish I could find a skin tint or balm in this color, so I could use it over a clear sunscreen. Until I find one, I'll have to keep fighting the Purescreen Tinted. Anyone have any suggestions?

Nice tinted anti-aging sunscreen
Size: 1.1 Fl Oz (Pack of 1)
I really, really like this sunscreen. I got the light color, and it fits close to my skin color. It has 21.6% zinc oxide which protects against UVA rays, and it has 30 spf for UVB rays. It has a dewy, shiny look and oily texture. Zinc oxide is a photo stable mineral UVA ray blocker, so this sunscreen doesn't degrade over time when you're in the sun. And this product has one of the highest concentrations on the market of zinc oxide (21.6%). I'll probably keep buying more in the future when I run out of this bottle. I bought a matte primer to apply first so that it mattifies this sunscreen when I put it on. Great product. I recommend.

One of the best affordable tinted minerals
Size: 1.1 Fl Oz (Pack of 1)
So I have tried many , many mineral sunscreens and chemical sunscreens. I prefer mineral for my face to prevent / treat hyperpigmentation. My favorite holy Grail is skinceuticals tinted mineral , but it's very expensive. I'm always on the hunt for a more affordable option. When I first got this I almost returned because it's not a tinted mineral in the sense that it evens out skin tone or hides anything (it's a peachy color to cover the white cast ) However , I like the ease of application and no white cast. It works great under my makeup and looks flawless. I've even done just concealer and bronzer and it still looks good. It's very hydrating / shiny though so if you don't have dry skin like me , you will not like it. If you skipped moisturizer it could be perfect. This is even a good one to wear to the beach and reapply without worrying you look like Casper. Lastly my bottle has NOT leaked like some other reviews have stated. I close the cap tight and when I apply it I hold it upright so it won't leak out ( it's a more liquid fluid to help it apply easily). I recommend !
