When Prevage was introduced, I wanted to try the active ingredient at a reasonable price. This led me to purchase my first bottle of idebenone serum from True Radiance. The serum is light, pleasant, easily absorbed, and nongreasy. It is also very effective. Within a month, I noticed a difference in my skin. The fine lines around my eyes began to diminish. My skin became clearer and more even. I regularly receive complements about my skin from others, even strangers. Thank you for offering this high quality product at a fair price. I will be a customer for life.
