No White Cast
Size: 1.7 Fl Oz (Pack of 1)
No white cast. I use the 2 finger method and have medium-deep skin tone. I have slightly oily skin and it does not leave my skin with a greasy, shiny or sticky either. I will definitely buy this again.

Best sunscreen in the market
Size: 1.7 Fl Oz (Pack of 1)
Very good quality sunscreen. Doesn't cause break outs. Good for sensitive skin. Invisible and blends into skin well but does leave a slight white dew to your face. This is okay with me though

Lightweight, Protective and Perfect for Everyday Use
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
Hawaiian Tropic Everyday Active SPF 50 sunscreen has quickly become my go-to for daily sun protection. The lotion feels light and non-greasy on the skin, which makes it easy to apply and absorb. There is no sticky residue or heavy feeling at all. I love that it’s broad-spectrum and water-resistant so I feel confident that it’s protecting me during outdoor activities, whether I’m at the beach, hiking or just running errands. Plus, being oxybenzone-free is a huge bonus for anyone mindful of ingredients. The scent is subtle and pleasant while not being overpowering like some sunscreens and the 8 fl oz size is perfect for keeping at home or in my bag. Overall, it’s effective, easy to use and keeps my skin safe and hydrated. Highly recommend for daily sun protection!

Lightweight and Smells Amazing
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
I was really impressed with how lightweight this sunscreen feels on the skin. It absorbs quickly and does not leave a greasy or heavy feeling behind. The scent is honestly one of my favorite parts because it smells so good and reminds me of being on vacation. I only used it on my body and not my face, and it worked perfectly for everyday sun protection. Overall it is such an easy, pleasant sunscreen to wear and I would definitely buy it again.
