Review title is Very Poor Design [SEP] Unfortunately, I cannot comment on the efficacy of this product because both bottles that I purchased had a faulty dispenser.  No lotion passed through them despite the fact that they appeared intact. I requested a refund and received it after shipping them back. Better quality control is necessary! I decided to try my 30% Vitamin C serum with Hyaluronic Acid on the scar and, to my astonishment, within a couple of weeks, the scar tissue was replaced with healthy new skin.
