Eucerin Original lotion – recommended for Canister and Pusher lubrication. Available from many supermarkets or online drug stores. Contains lanolin derivatives.
Apply any lotion or occlusive when fresh out of the shower. Choose a brand that is fragrance-free and dermatologist recommended. Eucerin has a great consistency for not interfering with the gripping of tapless devices. Other brands like Aveeno, CeraVe, Cetaphil lotion, Lubriderm, etc. may be just fine.
