Background

Granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as colony-stimulating factor 2 (CSF2), is a monomeric glycoprotein secreted by macrophages, T cells, mast cells, natural killer cells, endothelial cells and fibroblasts that functions as a cytokine. GM-CSF was first described as a growth factor that induces the differentiation and proliferation of myeloid progenitors in the bone marrow, which also has an important cytokine effect in chronic inflammatory diseases by stimulating the activation and migration of myeloid cells to inflammation sites, promoting survival of target cells and stimulating the renewal of effector granulocytes and macrophages. GM-CSF receptor is composed of one α chain and one β chain with low and high-affinity binding to GM-CSF, respectively, and the β chain is shared with IL-3 and IL-5 receptor. GM-CSF signals via signal transducer and activator of transcription, STAT5. In macrophages, it has also been shown to signal via STAT3. The cytokine activates macrophages to inhibit fungal survival.

Don’t rub, break it down between your fingers and dab!!
Style: 4 Fl Oz (Pack of 1)
Great sunscreen. The first time I applied it, i made the mistake of rubbing it in so it gave me a white cast. I learned my mistake the second time, spreading it in between my fingers and than dabbing it on my face, it gives a cast at first but after a few minutes it went away. And it feels so good. like I’m not wearing anything. I tried the tinted sunscreen it feels good but it made me look orange. I used to wear the Eucerin Daily Lotion spf 30 but they discontinued so I had to look for a replacement and after trying other sunscreens they were all terrible; greasy, allergic reactions and too creamy! This one’s perfect, it’s definitely my new go to!!

The Only SPF My Skin Will Tolerate!
Style: 4 Fl Oz (Pack of 1)
After 20 rounds of radiation, I was given a list of exactly four things I could put on my face--things like water and Vaseline. Of course, I was also instructed to wear SPF in "all visible light." However, finding a sunscreen my skin could tolerate proved to be a challenge, as even those made with clean ingredients, marketed for babies, and/ or claiming to be hypoallergenic resulted in hot, angry rashes. Price point also didn't matter; I tried everything from drugstore to premium brands. Thankfully, when this product came on the market, my dermatologist suggested I try it. I've been wearing it ever since. It IS thick so I usually rub any remaining face moisturizer into my palms and then add the Sunscreen, rubbing and warming it between my palms to make it more easily spreadable. Then I press it onto the skin on my face with my palms and fingers--I don't like to pull or tug too much at the skin on my face. At first, there is a visible white cast, but it disappears within a couple of minutes. If I'm really in a hurry, now I can mix a tiny bit of my foundation into the sunscreen so that it spreads faster and I can move on from the white cast faster--I know I lose some sun protection factor that way, but my derm says I also gain some protection in the tinting, so it's okay. The important thing is that I get it on in whatever time I have. I'm just grateful to have found something that doesn't upset my crazy-sensitive skin! Wishing all you sensitive beauties protected fun in the sun...

Good sun protection without chemicals, without a high price.
Style: 4 Fl Oz (Pack of 1)
I've bought this a couple of times. I feel like it gives excellent sun protection at a reasonable price. I mostly use it on my face. When I first apply it, it looks a little white and pasty, but it doesn't take long for that to go away. It's a little greasy at first , but I have dry skin, so I it absorbs in. I like using a sunscreen that doesn't have a lot of chemicals. This works well while using ingredients I feel good about putting on my skin.

A very effective sunscreen at a very reasonable price
Style: 4 Fl Oz (Pack of 1)
This sunscreen is very reasonably priced but would I love about this product more than anything is how effective it is at protecting your skin and will be my first go to when purchasing a sunscreen, and for a man, it is best to be clean shaven when using, and not to put on too much as it will make you look like Casper the ghost if you do

No scent and blends in surprisingly well.
Style: 4 Fl Oz (Pack of 1)
Eucerin 50 (Sensitive Mineral - Zinc Oxide) Expiration date: Sept. 2026 Purchase date: May 2025 The most noticeable ingredients in the sunscreen are zinc oxide, mineral oil, and a yellow tint. The sunscreen is not scented which is always a plus. The yellow tint was not noticeable on my deep bronze skin. My skin is sensitive to many chemical products but not this one. The product blended in well into my skin both when dry and when using a moisturizing toner. There was not a white cast after giving it a few minutes to be absorbed by the skin. Most oil-based sunscreens leave my skin feeling greasy when perspiring but the Eucerin 50 was a pleasant surprise. The perspiration felt normal and not greasy. Overall, I am very pleased with the product. It is great for active people who normally sweat away sunscreen. Eucerin 50 left my skin feeling very soft after washing it off. This is the first mineral oil-based sunscreen that I have found to be satisfactory. I believe it to be a good value at the twenty-dollar or less price range. Warning!: It can stain your clothing. Do not store oil-based sunscreens in a hot environment like your automobile. The ingredients will separate.
