Wang-Michelitsch and Michelitsch propose a hypothesis inspired by their misrepair-accumulation aging theory [12] for the development of age spots. [13]
To prevent AC from developing, protective measures could be undertaken such as avoiding mid-day sun, [2] or use of a broad-brimmed hat, [2] lip balm with anti UVA and UVB ingredients (e.g. para-aminobenzoic acid), [7] or sun blocking agents (e.g. zinc oxide, titanium oxide) [7] prior to sun exposure.
