The spacing on the one on the right is problematic; have a look at the salicylic acid on the front; the letters are too near to one another. Just a little bit of different writing appears all over the front. The front “Paula’s” also has poor kerning. The three emblems at the bottom on the back are likewise positioned differently. The top shouldn’t be that strange flip-top thing; it should just be the hole. In my opinion, it is phony.
Yes, it is excellent stuff. Paula started her work by reviewing other products/brands and providing honest reviews based on the legitimate scientific basis for the substances they included. She was always unbiased and discovered “great” things, “not so-great” products, and “terrible” products all under the same brand name.
