I just got back from The beautiful island of St Thomas USVI and used this product all throughout my vacation. I’m really picky about sunscreen formula and having dark combination skin, it’s pretty important that I find one I can work with. This was great! It was hydrating but didn’t feel too oily, the smell was subtle and not overwhelming, and I didn’t burn all week especially when I was on a different beach in different areas of the island it worked beautiful for me
