Irritated skin and too expensive
Size: 1.7 Ounce (Pack of 1)
It’s a good sunscreen. I like the smell and the consistency. However, I live in Denver, CO and it didn’t seem to protect my skin as much as I would like. It also eventually started drying out my skin and gave me a small rash that cleared up as soon as I stopped using it. This could be my personal experience, but it was too expensive and too small of a tube for me to justify continuing use.

Dewy and Effective Finish
Size: 1.7 Ounce (Pack of 1)
I recently started using the Cocoonkind SPF, and I’m really impressed with this product! It provides excellent sun protection without the greasy or heavy feeling that some sunscreens can leave behind. The formula is lightweight and absorbs quickly into my skin, leaving it feeling soft and hydrated. I also love that it’s made with clean, natural ingredients—knowing that it’s cruelty-free and free of harmful chemicals gives me peace of mind. The finish is dewy but not shiny, making it perfect for daily use under makeup or on its own. I’ve been using it every day, and it’s become a staple in my skincare routine. If you’re looking for a clean, effective sunscreen that provides great protection while nourishing your skin, I highly recommend Cocoonkind SPF! It’s gentle, effective, and perfect for all skin types.
