Final answer:
A gentle, non-abrasive all-purpose cleanser that is free from alcohol is used to de-grease the skin prior to chemical exfoliation. It effectively removes oils and dirt without causing irritation, ensuring that the skin is optimally prepped for the exfoliation process.
Step-by-step explanation:
Before a chemical exfoliation procedure, it is important to properly de-grease the skin to optimize the effects of the exfoliation and prevent any adverse reactions. A type of cleanser that is often used for this purpose is a mild, non-abrasive cleanser that does not contain alcohol, as using products with alcohol or other irritants can lead to skin irritation.
When de-greasing skin prior to a chemical peel all-purpose cleansers are favorable due to their neutral or weakly alkaline solutions, which are safe for use on skin and are effective in removing common kinds of dirt including oils and grease without over-drying the skin or causing irritation.
The act of degerming, such as handwashing with mild chemicals like soap, is a form of cleansing that significantly reduces microbial numbers on the skin's surface. Similarly, for pre-chemical exfoliation, the skin should be gently and thoroughly cleansed without scrubbing, which can aggravate conditions such as acne. Ingredients such as surfactants in the cleansers can help dissolve grease without the need for harsh scrubbing.
