This potent night serum will have you singing the blues — it won’t make you look like a Smurf, but it will smooth fine lines, repair damage, and strengthen the skin barrier while you sleep. Klairs’ tantalizingly named Midnight Blue Youth Activating Drop is formulated with powerful growth factors (EGF and FGF) to work not just on the surface of the skin but deep below to address the causes of fine lines. Featuring only 10 ingredients to give your skin only what it needs, this night serum fights free radicals, boosts collagen, and soothes skin irritated by UV rays, acne, and external stressors with blueberry extract, adenosine, and guaiazulene.

I got this Klairs drop about 3-3.5 weeks ago now, but I put off writing a review because for the first 2 weeks or so I wasn't seeing a change and I wanted to give it a chance.
