One of the Most Useful Skincare Products I Own
Title: One of the Most Useful Products for Mature Skin — Smooths, Protects, and Works Beautifully Under Makeup At 52 with post-menopausal dry, mature skin, I’m always looking for products that don’t just sit on the surface, but actually improve how my skin looks and behaves throughout the day. This surprised me in the best way. This is not a treatment product, and it’s important to set that expectation upfront. This is a barrier-supporting, smoothing balm, and when you use it for what it is, it performs exceptionally well. The texture is where it really wins. It’s a solid balm stick, but it glides effortlessly without dragging or pulling on the skin, which is critical for more delicate, mature areas. It melts just enough on contact and leaves behind a smooth, lightweight, conditioned finish that feels nourishing without being greasy or heavy. From a formulation standpoint, this is built around silicones and emollients that give an immediate soft-focus effect, combined with oils and butters that help reinforce the moisture barrier. There’s also adenosine for long-term wrinkle support and collagen extract for conditioning, though this is not going to rebuild collagen or act like a corrective serum. What it does do extremely well is improve the appearance of the skin instantly. It softens fine lines, reduces that dry, crepey look that can show up midday, and adds just enough slip and hydration to make the skin look healthier and more refined. Where I really love this is under makeup. It creates a smooth, hydrated base that helps foundation sit better and prevents it from catching on dry areas. It doesn’t pill, it doesn’t break anything down, and it adds that subtle cushion that mature skin really benefits from. I’ve also used it over makeup for touch-ups, and it works just as well without disturbing what’s underneath. This has quickly become one of those products I keep within reach because it’s so practical. It’s not about transformation — it’s about maintenance, comfort, and immediate visual improvement, which, for mature skin, is often exactly what you need. No irritation for me, and it layers seamlessly with the rest of my routine.

Consistency is the key
This product is amazing. You have to keep in mind that it doesn’t give instant results. However, consistent use will reveal wonders. I use my whole stick before I started to see results. When my stick was gone, is when I looked in the mirror and I was shocked. My forehead was tighter and lifted. My under eye bags had disappeared, and my eyes looked tighter. My skin was just so youthful looking. So I was like OK!! I need to order another one, I swear I didn’t think it was working at all until the sticker was gone. And I just woke up one morning and noticed a huge difference. I wonder if the changes will last?

The balm stick needs to roll all the way to the top
Overall I like the product itself I think its very moisturizing and it does seem to help the appearance of wrinkles however I think for the cost its pretty wasteful in the application. The rollup stops and there is still a ton of product on the bottle. I had to dig it out with my finger for a good 2 weeks worth of product I dont understand why it doesnt roll all the way to the top..

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.
