This is hands down the BEST serum I have ever used! Immediately after putting it on my skin felt amazing, but withheld judgement until the morning in case it was just the serum itself that felt nice... The next day my skin was as smooth and much more even in tone and texture than it ever has been! I tried leaving my skin for a few days after an application (no cleansing at all) and my skin is STILL at the best it has ever been! Definitely worth the price tag! Applies well. Even using a very small amount it spreads evenly and effectively across the face.
