Great Sunblock
Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
I've been using this sunscreen on my kids and even myself! It's been a great addition to our diaper bag. I like that the formula isn't runny, which makes application much less messy than some liquid sunscreens we've tried. It glides onto the skin easily. Most importantly, it works well and has provided reliable sun protection during outdoor activities, and I don't have to worry about it leaking in my bag. The only downside would be I still need to rub it in with my hands to get even coverage, but that's a small trade-off for how easy and convenient it is to use. I would recommend this to all my friends!

You will be bright white but not get burnt!
Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
I have sensitive and dry skin so most common to find products are just way too harsh for my skin. I didn't want to go the chemical route as my face would feel like it was on fire if I was in the sun with those chemical sunscreens. I also didn't like that the chemical sunscreens were not reef friendly and endocrine disrupters. Since our skin is the biggest organ, whatever you slather on is going to get absorbed into the body and system--I try to minimize the risk.
I knew I had to go the physical sunblock route and avoiding titanium oxide which isn't as safe as zinc oxide. Once you get all your requirements of what you want to avoid to stay healthy and safe (what's the point of sun protection to avoid burning and skin cancer but you end up getting other health issues by what you put on your skin anyways....defeats the purpose).
I was looking for a sunblock that had at least 20% non-nano zinc oxide, small ingredient list, and water resistant. This sunblock checked all the boxes. Sure it is small but it makes it easier to keep in your purse so you can reapply it as needed. You definitely will look quite white but I solved that by mixing it with a tinted sunblock or you can put in some foundation as others do to reduce the mime/clown/dead person look. It lasted well and I was not burnt in full Florida sun-even with some sweat it didn't burn or go in my eyes and the little stick made it easy to apply when I did smear some off my face on accident. When it came time to wash my face off, even with my mild cleanser, I just needed to make sure I really got my soap frothy and gently massaged my face to get it all off. My face was not red or irritated and no burns so it's a win!
There are a lot of sunscreens out there but with the chemicals that they use to 'absorb' the UVA/UVB rays...you are trading off for other health issues. So I know a lot of people prefer the chemical ones because they absorb better and blend in sheer but just remember that it is absorbing straight into your body and will give you other issues. There are enough additives and junk in everything else, let's be careful about what we put on our skin.

Kid Friendly Sensitive Mineral Sunscreen – Vegan and FSA Eligible (2026)!
Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz., Size: 0.5 Ounce (Pack of 1), Set name: Stick - 0.5 oz.
Kid friendly mineral sunscreen! I used this last year and repurchased it this year in the travel size for my toddler as she likes to apply sunscreen herself. The travel size is super easy and goes on well. Also does not make a huge mess when my toddler applies it herself. As you can see in the video, it doesn’t leave a very noticeable white cast, which is helpful when you have tan skin. Can easily reapply and not a hassle for a busy toddler. No sensitivity or rash after applying. It’s made for sensitive skin. I highly recommend for anyone who is looking for a good sunscreen for toddlers.

Best formula for Suntan Lotion.
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
I had this in regular formula and didn’t like it. The childrens one I love! Believe me, you need sunscreen, you’ll be glad you did as your sun loving girl friends wrinkle up and look older for not using it. It looks good on, not a white cast, not oily shining, or other awful things other sunlotion does. Doesn’t stink, actually makes your face look better as gives a better lighting to wrinkles (oddly, but woman have used mineral for generations for that very reason.) kids won’t skirm away, because it does sting.
