Hawaiian Tropics highly recommended for sensitive skin.
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Love this product. This is my first summer using it. I was not disappointed. I have super sensitive skin, and can’t use most products. One thing I did notice was a few times I would get a small pimple or blackhead along the lip line. The dermatologist said it was clogged pores, but no reason not to continue using it. I have tried a few other brands and had more breakouts/ blackheads. So I keep going back to Hawaiian Tropics.

Extremely Reliable Sun Protection for Active Days — A Must‑Have for Outdoor Sports
Style: SPF 70, Size: 2.5 Fl Oz (Pack of 1)
Summary:
This Neutrogena Sport Face Sunscreen SPF 70+ is powerful, long‑lasting, and perfect for intense outdoor activity. It stays put through sweat and heat, provides excellent protection, and prevents sunburn even under harsh Texas sun.
Details:
I’ve been using this sunscreen for about a year, and it has become an essential part of my sports routine. Since I play outdoor games in the afternoon, having a dependable sunscreen is non‑negotiable — and this one truly delivers. Even after long hours outside in the Texas heat, I’ve never experienced sunburn while using it.
The formula is designed specifically for active lifestyles. It’s sweat‑resistant and water‑resistant for up to 80 minutes, so it doesn’t wear off easily when you’re running, sweating, or wiping your face. Unlike many high‑SPF sunscreens that feel heavy, this one is oil‑free, non‑greasy, and doesn’t clog pores. It absorbs quickly and doesn’t leave a sticky or shiny finish, which is a huge plus when you’re active.
The Helioplex technology provides strong broad‑spectrum UVA and UVB protection, helping to prevent both burning and long‑term sun damage. It’s also oxybenzone‑free and octinoxate‑free, making it compliant with Hawaii Act 104 and suitable for people who avoid certain chemical filters.
Another great feature is its travel‑friendly 2.5 oz size, which is convenient to keep in your sports bag or backpack. You can reapply easily between matches or during outdoor activities.
If there’s anything to improve, a fully fragrance‑free version would be nice for those sensitive to scents — although the current light scent isn’t bothersome.
Overall, this is a dependable, high‑performance sunscreen for anyone who spends significant time outdoors.
What I liked
• Excellent sun protection — prevented sunburn even in intense heat
• Sweat‑ and water‑resistant for up to 80 minutes
• Oil‑free and non‑comedogenic — doesn’t cause breakouts
• Lightweight, non‑greasy texture
• Broad‑spectrum UVA/UVB protection with Helioplex
• Oxybenzone‑free and Hawaii Act 104 compliant
• Perfect travel size for sports or daily activities
What could be better
• A fragrance‑free option would be a nice addition

Solid sunscreen for active use
Style: SPF 70, Size: 2.5 Fl Oz (Pack of 1)
I’ve been using this sunscreen for outdoor workouts and beach days, and it works really well. It provides strong sun protection, goes on fairly lightweight, and doesn’t feel too greasy for a high SPF product. I also like that it holds up against sweat and water, so I don’t have to constantly reapply.
The only downside is that it can sting my eyes if I start sweating a lot, and it may leave a slight white cast if not blended in fully.
Overall, it’s a dependable sunscreen for sports and outdoor activities, especially for the price.
