How deep can a peel penetrate?

Peels differ in how deep they reach. This page starts from one source and turns its depth language into questions you can ask.
What the source says about depth
my.clevelandclinic.org states: "The different types of chemicals cause a controlled injury, each penetrating through to a different skin depth, then peeling away to reveal a new layer of skin."
It adds: "Different chemicals determine the depth of your peel and type of skin condition treated."
What those passages ask of you
Two points follow. Depth depends on the chemical used, and the chemical is matched to the skin condition. So never ask only how deep. Ask which chemical, and for which condition.
Steps for your consultation
- Say which skin condition you want treated.
- Ask which chemical the provider would use for it.
- Ask how deep that chemical goes, in the provider's words.
- Ask what a controlled injury looks like while the skin peels away, so you can plan around it.

If a term is unclear
Ask the provider to define depth words in plain terms. Readers around Saline can bring this page along as a checklist.
