Skin's changing condition throughout the day has been studied by SK-II, who recently revealed the result of its breakthrough research on the occasion of World Pitera Day.
For over six weeks, the Pitera 24/7 Skin Fluctuation Study monitored the skin of young women, in terms of texture, pores, redness, dullness, hydration and barrier function. The research found the skin fluctuates greatly within a day, even looking up to almost 10 years older due to multiple daily stressors. In addition, the facial complexion looks worst late at night.
