I tried out this sunscreen stick before spending a whole day walking outside and it kept me from burning. I was a little red at the end of the day but that's entirely my fault as I didn't re-apply once, considering how long I spent out (6+ hours), I'm impressed at its ability to keep me from burning. Personally this isn't a favourite of mine but it's a great size to keep in your purse for reapplication or for those times you don't expect to be outside and suddenly are. My reason for giving 4 stars instead of 5 is primarily the scent, I strongly prefer my products to not have a scent and this has a pretty strong scent. That being said, it isn't a bad scent or the typical sunscreen scent you get from Western products, kinda floral. Another factor for me was that it didn't come with a foil seal the way most products do so I can't be as sure of the freshness of the product. Overall happy with it and will keep it on hand when going out.
