C.O. Bigelow, makers of the beloved Ultra Mentha Lip Shine (one of my personal favorites) is turning 180 years old this year. To celebrate, they're pulling their retro Airstream trailer stocked with activities and beauty treats into Los Angeles, Tempe, Ariz., Dallas and Atlanta. If you live in or near one of those cities, you'll definitely want to check this out. The festivities will take place from 11a.m. to 5 p.m. on the dates below. Here's what you can expect to see/do per the company:

Design your own C.O. Bigelow "Honest. Genuine. Trustworthy." (the company's motto) T-shirt

Receive a problem/solution skincare consultation from a C.O. Bigelow expert to create a personalized Bigelow skincare regimen

See how Lemon Body Cream (one of their best sellers, and so delish) is created and walk away with a FREE sample from a fresh-blended batch.
