Final answer:
To stop the action of a chemical exfoliant, a neutralizing agent is used. This helps restore the skin's normal pH and prevents over-exfoliation. Gentle aftercare using alcohol-free products and lukewarm water is also crucial.
Step-by-step explanation:
The product used to stop the action of a chemical exfoliant is commonly referred to as a neutralizing agent or neutralizer. After the application of a chemical exfoliant, such as a glycolic acid or a salicylic acid peel, it is important to halt the acid's effect to prevent over-exfoliation and damage to the skin. This can be done using a neutralizer which often contains an alkaline substance to balance the pH and restore the skin's normal pH. It is crucial to carefully follow the instructions for the exfoliant and the neutralizing agent, including using lukewarm water for rinsing and avoiding products that may further irritate the skin.
Failure to neutralize a chemical exfoliant can result in excessive peeling, redness, or even burns. Therefore, it's important to use only alcohol-free products and to avoid harsh astringents or additional exfoliants during the healing process. Post-exfoliation care is critical. In this period, it's recommended to reduce microbial load on the skin through gentle techniques and the use of mild chemicals, avoiding extreme temperatures in water, and ensuring all products used are suitable for post-exfoliation care.
