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.
