Examples of physical sunscreen include which of the following?

• A. Avobenzone and octisalate
• B. Octocrylene and homosalate
• C. Titanium dioxide and zinc oxide
• D. Oxybenzone and ecamsule

Answer: (C)

Physical sunscreens, also known as mineral sunscreens, primarily use mineral-based ingredients to create a barrier on the skin that reflects and scatters UV radiation. Titanium dioxide and zinc oxide are the two key active ingredients in physical sunscreens. They are recognized for their efficacy in shielding the skin from both UVA and UVB rays, making them popular choices for individuals seeking broad-spectrum protection. Titanium dioxide works by absorbing some UV light and reflecting a portion of it away from the skin, while zinc oxide provides a broader spectrum of protection due to its ability to block a wide range of UVA and UVB rays. Both ingredients are considered safe and effective, particularly for sensitive skin types, as they are less likely to cause irritation compared to chemical sunscreens. The other choices listed in the question consist of chemical sunscreen ingredients that absorb UV radiation, rather than reflecting it, which differentiates them from physical sunscreens. Understanding the role of these active ingredients is crucial for estheticians, as they guide clients in selecting appropriate sun protection based on their skin types and concerns.
