When staring at the wall of sun protection methods you should keep your family's needs in mind. General sunscreens provide normal protection and specialty ones cater to age and protection location. Some come with tanning agents or moisturizers to help with your skin health.
If you're looking for a one-stop convenient sunscreen for the whole family, spray sunscreens are a great choice. They come in various SPF strengths and are easy to use. Spray evenly on all exposed areas of skin and normally there's no rubbing necessary, just allow to air dry. Bullfrog's Marathon Mist is a great waterproof spray that doesn't require pumping and provides even coverage.
Many sunscreens now come in stick form much like deodorant. These can be very convenient, especially for travel, such as the Neutrogena Oil-Free Sunblock Sticks which are sized for TSA guidelines. This should be an individual option, as sharing stick sunscreen could be unsanitary.
Traditional lotion sunscreens come in many forms, including mosquito-repellant, tanning, and moisturizing. A slightly less common but highly rated brand, Blue Lizard, has been recommended as a top brand by the Environmental Working Group. Their lotion sunscreens come in regular, sport, baby, face and sensitive skin formulas.
