Products that are 3.4 ounces (100 mL) or less are considered travel size. Travel size bottles and other containers that meet these weight and volume criteria can be brought onboard an airplane in a carry-on bag. However, it’s important to remember that passengers are often limited to one quart-sized plastic bag of liquids, creams, and other TSA size bottles of other personal-care products.

A majority of SkinCeuticals full-size products come in approved TSA size bottles. In fact, our serums, moisturizers, masks, and sunscreens all meet the U.S. Transportation Security Administration’s requirements for travel size products that can be packed in carry-on luggage. At this time the only SkinCeuticals products that are not available in travel size are our cleansers, toners, and body treatment lotions. However, you can decant your home-based products into TSA size bottles to avoid checking your luggage when you fly. You can do the same for your gym bag, or any other time you want to take your full SkinCeuticals regimen to go.

Yes, travel size products have expiration dates, and it’s important to be mindful if you don’t travel that often. However, if you are using your SkinCeuticals products daily (although they are technically travel size) this shouldn’t be a concern. Just remember that most skincare products (travel size or not) have a shelf life of 10 to 12 months after being opened, while our vitamin C antioxidant serums are best used within six months after opening.

For optimal UV protection, sunscreen should be reapplied every two hours, as well as after sweating. Our travel size sunscreen products take up minimal room in even the smallest bag, and allow you to reapply as recommended to maintain your sun protection throughout the day.
