Lightweight, Effective & Smells Great
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
This sunscreen works amazing! The Neutrogena Beach Defense SPF 70 gives excellent sun protection without feeling too heavy or greasy on the skin. I really like that it doesn’t have a strong overpowering smell like many other sunscreens. It’s lightweight, absorbs quickly, and feels comfortable for everyday wear or beach days. The water resistance is great and it protects well even during long hours outside. Perfect for the whole family and definitely worth buying again!

Affordable and reliable sunscreen
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1), Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
This sunscreen is a great everyday option, especially for the price. It provides strong sun protection without feeling heavy or greasy. I like that it works well for both face and body, which makes it convenient to carry just one product. It also has a nice moisturizing effect, so my skin doesn’t feel dry after applying. The lotion spreads easily and absorbs quickly, which is perfect for busy mornings or beach days.

Good product! Weird smell.
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
I love the smell of sunscreen. Banana boat, Coppertone, it doesn't matter. So I'm not bothered by "sunscreen smell." But this isn't sunscreen smell. It's more chemically than that. It's not even necessarily "bad" per se, it doesn't stink, but it's not something I would personally choose to smell like in other circumstances. Almost a little plasticky. Besides that, it's extremely wearable. Blends in to my skin no problem, leaves a moisturized but not greasy feel on the skin. If you can deal with that strange smell, which seems to fade after a little
