Researchers compared photoaging in men and women from Australia over a four year period between and Photoaging is associated with coarser and slack skin, increased wrinkling and dryness, an increase in visible small blood vessels and white and blackheads on the face. The adults, who were all under age 55, were randomly assigned to two groups. They were instructed to apply it to their head, neck, arms and hands every morning, and to reapply after heavy sweating, swimming, or spending more than a few hours outdoors.

By the end of the study, 77 percent of the participants told to use sunscreen every day were applying sunscreen at least 3 to 4 days per week, compared to 33 percent of discretionary users.
Compared with discretionary sunscreen users, those assigned to daily sunscreen use were 24 percent less likely to show increased aging. The skin-saving effect of sunscreen was observed in all daily-use participants, regardless of age.
