Avobenzone

What it does

Avobenzone is a chemical sunscreen filter that absorbs UVA radiation (320-400nm) and converts it into heat, providing broad-spectrum protection. It is photounstable on its own and degrades when exposed to sunlight, which is why it is typically stabilized with other ingredients like octocrylene or photostabilizing agents in formulations.

Benefits

• Protects against long-wave UVA rays that cause photoaging and skin damage
• Broad-spectrum coverage when combined with UVB filters
• Cosmetically elegant; less visible white cast than mineral filters
• Approved globally for sun protection (FDA, EU, others)

Who it suits

• All skin types
• Those seeking chemical sunscreen options
• Sensitive skin (when properly stabilized and formulated)

Safety & cautions

Avobenzone is photounstable and degrades in sunlight, requiring stabilizer ingredients to maintain efficacy; higher concentrations and proper stabilization ensure effectiveness. Some individuals may experience sensitivity; patch test if prone to fragrance or chemical sensitivities.
