Both exfoliants contain Salicylic Acid, but each adds something the other doesn't. Here's where they overlap and where they split.

A high-strength weekly at-home peel combining 25% AHA and 2% BHA with soothing extracts. Strong resurfacing for experienced acid users; a once-weekly treatment only, with strict SPF the next day.
