Derma-E Ultra Lift DMAE Serum

Derma-E Ultra Lift DMAE Concentrated Serum. Tightens and tones. I use other Derma-E products and decided to try this one. I'm highly sensitive to any products that has anti-aging properties. I used this product once and although it felt great on my skin, there is an ingredient in it that I'm allergic to. I only used this product once. 1 fl. oz.
