Sun Bum Baby Bum Mineral SPF 50 Sunscreen Lotion review

Sun Bum Baby Bum Mineral SPF 50 Sunscreen Lotion is the value pick among the verified prices. It costs $16.49 for 3 oz on sunbum.com, about $5.50 an ounce, the lowest per-ounce price we could confirm. The active ingredient is zinc oxide at 20%, in a base of water, coconut oil, shea butter and cocoa butter. Sun Bum lists it as fragrance free, pediatrician tested, water resistant for 80 minutes, vegan, gluten free, cruelty free, made without parabens, and Hawaii Act 104 compliant, meaning no oxybenzone or octinoxate. The same Baby Bum formula is sold as a spray and a roll-on at $16.49 and as a face stick at $13.49, and a spray and stick bundle costs $26.98. It is labeled for babies, but nothing on the page limits it to babies, so it works for toddlers and young kids too. The main limits are bottle size and shipping: Sun Bum says it cannot ship regulated items such as aerosols to Hawaii, Alaska or PO boxes.
