Beef Tallow Sunscreen
That dry, stretched sensation that I sometimes get from using other sunscreens was not something that I experienced with this one. On the contrary, I had the impression that my skin remained supple and pleasant throughout the morning. I used it prior to going about my errands, having a drive, going for a stroll outdoors, and spending time at the park. To my satisfaction, I did not feel the need to quickly apply another moisturizing lotion on top of the one I was using in order to restore the natural feel of my skin. Simply said, it made it simpler for me to utilize on a daily basis. When I wore it for a longer period of time, I also paid attention to how it felt on my face. Even though I wore it on a number of days when the temperature was high, I did not experience any discomfort as the day progressed. Despite the fact that I was aware that I was wearing sunscreen, I did not feel any discomfort or want to wash my face straight away with it. Because I am quite particular about the products that I use on my face, I found that to be really helpful. In addition to having a sunscreen that is dependable, I want it to be something that I can really endure for a considerable amount of time.

The Best Way to Keep My Skin Happy Under the Sun
I am so happy that I found this special white cream because it is the best helper for my face and arms when I am playing outside in the big bright sun. I keep the bottle right near my sink so I can put it on before I go out to play, and it is very easy to use because the cream feels very smooth and soft like butter when I rub it on my skin. Sometimes other white creams feel very chalky or yucky like flour, but this one is a great deal for the price because it blends in so well and it does not leave a big white ghost face on me once I rub it in. It feels very simple and clean on my skin and it does not have a scary or strong smell, which makes me very happy because it does not feel greasy or oily like a piece of pizza. Even when I put more on later in the day, it does not clog up my skin or feel heavy like a thick blanket, so it is a wonderful value because I can use it all day long and stay comfortable. The tube is a perfect size to throw in my backpack or my travel bag when we go on a trip, and it feels very strong and tough like it will last a long time without the cap breaking off. It is a very practical and smart tool for my skin because it forms a strong layer that I can see at first to make sure I am safe, and it feels much better and more dependable than thin lotions that disappear too fast. I think everyone who likes to be outdoors should get this because it is durable, it works perfectly to keep me safe, and it is so simple and easy to use that it never gets in the way of my fun!

Comfortable to Wear and Easy to Use Every Day
The texture was the first thing I felt. First application feels rather rich but unexpectedly distributes easily throughout the skin. I was worried it would feel heavy, but it blended in more readily than I thought and didn’t leave my skin feeling too oily afterwards. I love that you can use it on the body and face too. One product for the entire family is easier and saves room when packing for trips or holidays. I have used it on myself and my kids when we go out and it has been comfy for all of us to wear. Another thing I appreciate is my skin feels hydrated after using it. Love things that make my mornings easier on hectic mornings. The mixture is smooth and pleasant to wear all day long and does not feel sticky. The container is functional and simple to throw in a beach bag or handbag. I have brought it to soccer games, trips to the playground, family picnics and it has been no problem.

Less cast and the zinc scent is mild.
I use sunscreen regularly. One of the aspects I do not like is the white cast I get from zinc-based SPFs. This one is zinc-based but it has tallow and PDRN. I want to see if they make any difference when it comes application and feel. MY EXPERIENCE WITH THE PRODUCT 1. I received Mystic Orchard’s beef tallow sunscreen with PDRN. Comparing its value, I think the volume is pretty good. I received 2.8 ounces. 2. When it comes to scent, I smell the metallic scent but it is not as bad as the one I have been using for swimming. It is there, but pretty faint. 3. You can tell by the sheen that it is zinc-based. It has the same consistency. 4. What I noticed though is that the white cast is not too bad. It blends fast with the tallow. 5. I like tallows because they contain fat-soluble vitamins like vitamin E for some antioxidants. 6. The cica is nice too for those who need a calming ingredient with their sunscreen. 7. I think this would be good for when going out. I do not think I will be using it for swimming since it is mild in scent and cast. Better to use it elsewhere than just for swimming. OVERALL IMPRESSION: I think that this SPF sunscreen with tallow and PDRN is cost-effective and worth its value if you want a zinc-based sunscreen with less cast and milder scent.
