UVA and UVB radiation from the sun can lead to two of the most feared and hated maladies: cancer and wrinkles.
Certain compounds in sunscreens that protect against harmful radiation can cause an allergic reaction, however.
Para-aminobenzoic acid (PABA)-based chemicals are the most common culprit, according to WebMD, which recommends switching to a PABA-free sunscreen if you develop an allergy.
Parents magazine cites the ingredient oxybenzone. For babies older than 6 months, the magazine recommends a broad-spectrum sunscreen with an SPF of at least 30 that’s made with naturally occurring minerals like titanium dioxide and zinc oxide, which are less likely to inflame skin or sting eyes.
