What is the primary function of enzymes in skincare?

1. Moisturizing the skin

2. Exfoliating dead skin cells

3. Proteolytic (protein dissolving)

4. Increasing blood circulation

The correct answer is: Proteolytic (protein dissolving)

Enzymes play a crucial role in skincare primarily through their proteolytic function, which means they help in the breakdown of proteins. This process is essential for various skin functions, including the removal of dead skin cells. By dissolving proteins that hold these dead cells together, enzymes facilitate a gentle exfoliation process, allowing for a smoother and more radiant complexion. Additionally, this enzymatic action can enhance the penetration of other active ingredients in skincare products, making them more effective. While moisturizing the skin and increasing blood circulation are important aspects of skincare, they are not the primary functions of enzymes. The focus on the proteolytic property highlights the unique role of enzymes in promoting skin renewal and maintaining overall skin health.
