Worth it!!
These are my favorite eye patches because they stay put, blend well so you don’t look freaky if you’re wearing them during the day etc. and they work! They’re my go to when my under eyes need some extra help, which in my mid 50’s is almost all the time!! Worth the money!!

Beef Tallow Sunscreen Stick (Kid-Friendly)
Our family absolutely loves this beef tallow sunscreen stick! It’s become a must-have for park days, sports, vacations, and everyday outdoor activities. The stick format makes application quick and easy, especially when applying sunscreen to active kids who don’t like standing still. The formula glides on smoothly and feels moisturizing without being greasy. I love that it’s made with simple, skin-friendly ingredients and mineral sun protection, making it gentle enough for sensitive skin. My kids haven’t experienced any irritation, and it helps keep their skin soft and protected even during long days outside. One of the biggest benefits is how convenient it is to reapply. The stick fits easily in a backpack, diaper bag, or purse, and there’s no messy lotion to spill. It works great on faces, noses, ears, and shoulders, which are often the areas most exposed to the sun. Why We Love It: - Kid-friendly and easy to apply - Gentle on sensitive skin - Moisturizing with nourishing beef tallow - Convenient, mess-free stick format - Great for outdoor adventures and travel - Mineral-based sun protection Overall, this sunscreen stick provides reliable protection while keeping skin moisturized and comfortable. It’s a fantastic option for families looking for a simple, natural, and kid-friendly sunscreen that makes sun protection easy for everyone. Highly recommended!

Obsessed with this sunscreen stick!
Just got this Beef Tallow Sunscreen Stick and I'm honestly really impressed! I wasn't sure what to expect since I've never used a tallow based sunscreen before, but it feels so nice on my skin. It glides on super smoothly, doesn't leave a weird sticky feeling, and makes my skin feel moisturized instead of dry like some sunscreens do. I also love how easy it is to throw in my bag and just reapply throughout my day. The ingredients are a huge plus for me too ofc! I like that it's made with beef tallow, honey, and beeswax instead of a bunch of stuff I can't pronounce. I've worn it outside for a few hours already and it held up great. No irritation, no white cast, and my skin felt really soft afterward. Definitely happy with this purchase and I'll be keeping it in my daily routine. Highly recommend if you're looking for a more natural sunscreen option!
