Final answer:
Exfoliating chemicals that dissolve or loosen dead cell buildup are primarily acids and enzymes, used in skincare to promote cell turnover for healthier skin.
Step-by-step explanation:
Exfoliating chemicals that dissolve or loosen dead cell buildup are commonly known as acids and enzymes. These substances aid in skincare by promoting the removal of the outer layer of dead skin cells, revealing fresher and healthier skin underneath. Acids, such as alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs), work by breaking down the substance that holds dead skin cells together, allowing them to be washed away. Enzymes, on the other hand, work by breaking down the keratin protein in the dead skin cells, effectively digesting them so they can be easily removed. Both acids and enzymes are used in various skincare products to help achieve smooth and clear skin.
To answer the student's question directly, the exfoliating chemicals that dissolve or loosen dead cell buildup are c. Acids and b. Enzymes.
