It works
Size: 6.7 Fl Oz (Pack of 1)
Well this product works. At first I thought maybe the Caribbean sun wasn’t as bad as people said since I was in the sun for 4 days wearing this sunscreen and hardly had tan lines, then I tested my theory for 1 day with another brand and got a sunburn. I took star off (would really only do a half if it allowed) for when you go in the water or if you sweat there is a bit of white residue that it leaves.
But for sun purposes, if you want protection, I highly recommend.

A must have for superior sun protection!
Size: 6.7 Fl Oz (Pack of 1), Size: 6.7 Fl Oz (Pack of 1)
Neutrogena Beach Defense SPF 50 is an absolute game-changer when it comes to sun protection. Whether you're relaxing at the beach, swimming, or enjoying an outdoor adventure, this sunscreen provides broad-spectrum protection that effectively shields the skin from harmful UVA and UVB rays.
One of its standout features is its lightweight texture, it glides effortlessly onto the skin without feeling greasy or heavy. Unlike some sunscreens that leave a sticky residue, Beach Defense absorbs quickly and smoothly, making it ideal for both face and body application.
Another major plus? Water resistance! This formula stays put, even after swimming or sweating, ensuring continuous protection throughout the day. And despite its strong defense against the sun, it feels refreshing and comfortable on the skin, making reapplication a breeze.
I used it during a vacation in the Dominican Republic, and me and my family enjoyed it. My 5 years old girl has been protected from the sun all the time.
If you're looking for reliable, effective, and easy-to-use sun protection, this sunscreen is an excellent choice. Highly recommended! ☀️👌
