Healed my acne

This serum saved my face and I've recommended it to friends, who have also used it.

Buy it!

Tried & true! My skin stays clear and glowing when this is consistently in my routine. If you are acne prone, this is an absolute MUST.

One of the favorites

Great treatment. I've used it on and off for a few years and can definitely tell my skin loves it. Quality ingredients.

Excellent for clearing up and exfoliating skin

This is a great treatment for congested, spotty, combo skin. Do not use any exfoliators or acid toners in the same routine - it would be too aggressive. I apply this serum after cleansing at night and follow with night cream. I do not use this on the nights when I use prescription tretinoin, too much for skin to handle.

Life saver

So honestly this product has been life changing for me. I've struggled with acne pretty much my entire life and have spent thousands of dollars looking for "that" product to help. It took two weeks for this product to transform my skin. It is still not perfect after a month of use but still improving daily. I'm so grateful for this product and company.
