It is done three or more times at one to two week intervals. Shine and small clogged bumps tidy up over two to four weeks, because it takes time for accumulated oil to clear and for new output to fall. It does not finish in one go — it is repeated on a regular schedule.

Downtime is mild at one to three days, and slight flaking can occur — a natural response as the surface tidies up while dead skin is cleared. It dissolves rather than scrubs, so it is relatively gentle even on skin with inflammation.

Aquapeel physically draws debris out of pores with water jets and suction. Black Peel uses an oil-soluble ingredient and charcoal to regulate the oil itself, which suits shine as the main concern. If a lot is already hardened and blocked, Aquapeel comes first.
