Each Nourish London product features a 'period after opening' logo on the packaging, which tells you how quickly you should use it up after first use - it is generally 6 months.Left unopened, the products will last from 24 to 30 months from the date of manufacture even with the natural preservative systems we use. The date of manufacture is a 6 figure code stamped on the side of your product and its packaging.To make sure they don't go off quicker, we advice to store them out of direct sunlight and in a cool and dry area.
