I see a lot of posting on Witch Hazel in which Dickinson's is mentioned.

I never used Witch Hazel myself, but I remember when I was a kid my dad always did.

The CVS product specs for regular Witch Hazel read: USP. Gently tones skin. Astringent for face & body. Cleans & refreshes. CVS pharmacist recommended. Square bottle uses less plastic than a similarly sized round bottle. Recyclable (if available in your area).

I also looked up Dickinson's Witch Hazel All Natural Astringent: 100% All natural botanical. Deep cleaning. Our unique 100% natural formula gently removes excess oils, makeup and impurities from your skin without disturbing its natural moisture balance - leaving it soft, smooth, and refreshed! The Benefits of Witch Hazel: Gentle, non-drying; 100% All natural; Cools & refreshes; Dermatologist tested & recommended. No animal testing. Made in USA.

Is there any real difference between Dickinson's and just plain old Witch Hazel?

And, why use it?
