NO-AD is a line of sunblock lotion that I first found at Wal-Mart, it was cheaper than any of the other brands because they don't spend any money on advertising. I assume it is available in other stores as well, especially large discount stores. It is also available in Peru, but is much more expensive here.
It comes in the various common SPF ratings in a lotion, as well as I have some in "stick" form like a large lipstick tube. It also is available in various formulations, including for children and babies, as well as for sunless tanning.
It is waterproof and sweatproof, has a pleasant non-overpowering smell (not coconut!) and is non-greasy. According the the label, it retains its SPF rating up to 80 minutes of activity in the water or sweating. It contains aloe vera, cocoa butter and vitamin E, and provides a broad spectrum UVA and UVB protection for the skin. The active sunscreen ingredients are Octinoxate (Ethylhexyl Methoxycinnamate), Octisdalate (Ethylhexyl Salicylate) and Oxybenzone (Benzophenone-3).
