Young Face essential facial serum is essential to add to your skincare ritual. Once you try this product you will not be able to live without it, just ask my husband. Use on a clean face. If you use toner add the serum after this step and before your moisturizer. Some like to use this for their moisturizer others still enjoy using a moisturizer after the serum. Either way you will still reap all the benefits this amazing serum has to offer!
