Frequently Asked Questions

Your questions answered about iS Clinical EDU and its resources for skincare professionals.

Chemical sunscreens absorb UV rays using organic compounds, while physical (mineral) sunscreens reflect them using minerals like zinc oxide and titanium dioxide. Both types can provide effective broad-spectrum protection when properly applied.

SPF, or Sun Protection Factor, measures how well a sunscreen protects against UVB rays, which cause sunburn. Higher SPF numbers indicate longer protection, but all sunscreens should be reapplied regularly for consistent defense.

A broad-spectrum sunscreen provides protection against both UVA and UVB rays. UVA rays contribute to visible signs of aging, while UVB rays primarily cause sunburn. Using broad-spectrum protection daily helps maintain healthy-looking skin.

The concept of double defense refers to the use of both antioxidants and sunscreen together as a combined approach to protecting the skin from the visible effects of environmental exposure. Antioxidants help defend against free radical damage that can occur even with sunscreen use, making the two work more effectively together than either would alone. This course explains the double defense philosophy and how to build it into client regimen recommendations.

Selecting the right sunscreen depends on skin type, lifestyle, and texture preference. For oily or acne-prone skin, lightweight matte finishes are ideal, while dry or mature skin benefits from hydrating formulations with antioxidants. Encourage consistent daily use and proper reapplication.
