Chris Christensen Peace & Kindness Colloidal Silver Gel 8 oz

A: Hello Mary, all Chris Christensen liquid products are 'best before' 36 months after the manufacture date. A good rule of thumb is that any product without an expiration date (like cosmetics) is shelf stable for 3 years from the time of manufacture, as long as they are stored at room temperature in a dark location. Additionally, it is important to note that if products freeze or are exposed to extreme heat, it may alter their functionality and performance. May this serve you well in your endeavors!
