Nambour study from Australia is the first randomized controlled study to prove that daily sunscreen usage can help prevent premature photoaging of skin. The participants were divided into two groups, daily use vs discretionary use of sunscreen. The daily sunscreen group showed no detectable increase in skin aging after 4.5 years! Skin aging from baseline to the end of the trial was 24% less in the daily sunscreen group than in the discretionary sunscreen group (relative odds, 0.76 (95% CI, 0.59 to 0.98]).
Remember to use a sunscreen with at least a SPF of 15 daily to prevent premature aging of your skin.
