INTRODUCTION & OBJECTIVES

Long-term studies dealing with the photoaging process are scarce, mostly for practical issues. This study was to assess, in reallife conditions, the effectiveness of a strong photoprotection (SPF 60, PPD=24 [UVA/UVB]>1/3) in counteracting the photoaging process of some facial signs over a one-year period of twice-daily applications.
