The Tower 28 SOS Daily Rescue Facial Spray ($28) is Liu's only skin-care product and the one she's most proud of. With a seal of approval from the National Eczema Association in the US, "the exciting part about that product is that because it's antibacterial and anti-inflammatory it has honestly been the one product that has calmed down my chronic eczema," said Liu, adding that "we named it SOS because it's literally saved my skin."
