Who has time to run to the drugstore, buy tiny bottles and fill them with your favorite beauty products, all the while being observant of the 3 oz. security rule? Not the busy TFS staff. And likely not you. This is why an all-in-one skincare kit could just be the thing. In exactly the right quantities, you get moisturizers and cleansers as well as shampoo and conditioner. With ingredients like grapefruit, peppermint, bergamot, Vitamin E, and cilantro, it's no surprise the SOHO Grand Hotel in NYC offers these in their room as amenities.
