Putting on sunscreen every day can stop your skin from getting worse from sun damage, and might even help fix some of the wrinkles and spots you already have.

Assessment Explanation
The claim uses 'may induce,' which correctly reflects uncertainty in reversal effects. Prevention of photoaging progression is supported by robust RCTs (e.g., N Engl J Med 2013), but reversal of existing damage is less certain and observed only in limited studies with modest effects. The phrasing balances established prevention with tentative reversal, avoiding overstatement. 'May induce' is the correct verb strength for the reversal component, while 'prevents' is justified for progression based on longitudinal evidence.
More Accurate Statement
“Daily application of broad-spectrum sunscreen prevents the progression of photoaging and may partially reverse some existing signs of sun-induced skin damage.”

Sunscreen and Prevention of Skin Aging
People who used sunscreen every day for almost five years had much less skin aging than those who used it only sometimes, meaning daily sunscreen helps stop sun damage from getting worse — and may even help fix some of it.
People who used sunscreen every day for a year saw their sun-damaged skin get noticeably better—not just protected from more damage, but actually healing in ways like smoother texture and fewer dark spots.
This study found that using sunscreen every day helps stop skin from aging too fast from the sun—and even helps fix some of the damage already done, like wrinkles and dark spots.

This study says using sunscreen every day helps stop sun damage from getting worse, and some ingredients in sunscreens might even help fix some of the damage already done.
