See the Love Your Skin 2018 Event.
The Glowing Skin Event (which was a broader event introduced in 2016 from the smaller Love Your Skin Events in previous years) is once again called the Love Your Skin Event. From 01/08/17-01/28/17, the event will feature daily steals and promotions that run throughout the entire period. These 3-week long promotions are common for Ulta. Unlike The 21 Days of Beauty and the Gorgeous Hair Event (which are also 3-week long promotions), the Love Your Skin event only happens once a year. Every year, I hope they will offer this in July, but they have not done so yet. I have not given up hope that they will start offering this twice a year as they do with other major promotions. Although, winter skin does typically need more TLC, so I think January is the perfect month to host the event if it only happens once per year. An event schedule is available online.
