After one full year of using the product twice daily, I’ve noticed less redness and a subtle plumping effect that’s smoothed fine lines, particularly on my forehead and around my eyes." — <em>WWD Shop Senior Beauty and Lifestyle Commerce Editor Claire Sullivan </em><br><br><strong>Price upon publish date of this article: </strong>$12.99
