Sunblock:

• Mechanism: Physically blocks and reflects UV rays from the skin using mineral ingredients like zinc oxide or titanium dioxide.
• Characteristics: Typically thicker, may leave a white cast on the skin. Provides broad-spectrum protection immediately.
• Best For: Sensitive skin; those seeking a natural, less irritating option.

Sunscreen:

• Mechanism: Absorbs UV rays and converts them into heat using chemical ingredients like avobenzone or octocrylene.
• Characteristics: Lighter and often more transparent than sunblock. Available in various formulations like lotions, gels, and sprays.
• Best For: Daily use; those preferring a lightweight feel and less visible residue.

Both sunblock and sunscreen protect against UV damage, but the choice depends on skin type, texture preference, and specific needs.
