All massage lubricants have a limited shelf life and each type and brand comes with its recommendations. While not exactly an expiration date, shelf life can range from as little as 6 months up to 2 years, and it is important to take it into account to prevent allergic reactions. Salt and sugar scrubs also come with limited-time usage recommendations — usually, 18 months at room temperature. Bath bombs, bath salts, body washes, and facial cleansers have a similar shelf life but make sure to check the packaging and write down the opening date. To help them last longer, store essential oils, skin care products, lubricants, and other related massage supplies in a cool, dry place, away from direct sunlight.
