Discoloration correcting serum in a tinted glass dropper bottle. The liquid is white and unscented. The inside of the opening has something to remove any lingering liquid from the outside of the dropper so excess product isn’t wasted. I used the serum on areas of pih twice a day. I didn’t see any results and im almost done with one bottle. Sometimes i use too much product so i may have used too much and used it up too quickly. The improvements made to the product over time are listed on the box based on what people have recommended.
