All Alexandr&Co. products contain an expiry date which is usually indicated on the back of the packaging. However, once opened all products should be stored covered in a room temperature such as a dressing table or bathroom and can last up to 12 months or until the stated expiry date, whichever occurs sooner. Exposure to light may cause Seriguard Moisturizer and Serishine Eye Cream to develop mild yellow discoloration, therefore we recommend keeping products sealed and away from sunlight at all times.
