C.E.O. is Sunday Riley’s vitamin C heavy-hitter: 15% THD ascorbate (the fancy, stable form that absorbs beautifully) to brighten the look of dark spots and bring back bounce. It sinks in fast with no sticky finish, so it layers under moisturizer and makeup. (Mine is the mini from my Wake Up With Me set — the link goes to the 1 fl oz bottle, and the listing has other sizes to pick from too.)

Why We Like It:

  • 15% THD ascorbate — a stable form of vitamin C that absorbs beautifully
  • Brightens the look of dark spots and dullness
  • Sinks in fast with no sticky finish
  • Layers cleanly under moisturizer and makeup

Best For: Anyone chasing a brighter, more even look — especially if dullness and dark spots are the main complaints. Use it in the morning before moisturizer and SPF.
