I found a bottle of this ghost I realized I hadn't used yet, and wondering if it can be used without harming my skin, or will the efficacy of the product diminish ?

Thank you

Hello Michelle28,

It would help us greatly to know the Lot # and Manufacture date on the back label. Many of our products do not lose efficacy for 3-5 years. Is there a chance you could give us a bit more information? We would always welcome a call into our office. Our customer service line is toll free: 1.800.405.1912. We are open Monday - Friday 8:00 AM to 5:00 PM.

Keep Smiling,
