Avobenzone
Avobenzone is a chemical UV filter that absorbs across the full UVA spectrum — the range most responsible for pigmentation and premature aging — but it's chemically unstable on its own and breaks down under sunlight unless a formulation pairs it with a stabilizing co-filter.
How it works
An organic UV filter that absorbs across the UVA spectrum by undergoing a reversible photochemical shift, though it degrades on UV exposure unless stabilized with photostabilizing co-filters.
In practice, whether a sunscreen containing it actually performs as labeled depends on that stabilization — not something to evaluate from the ingredient list alone.
How to introduce it
No wait needed — apply the next step right away. Judging Avobenzone before week 1 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
- Every morning, no exceptions — this is what makes every other active safe to use.
- Reapply after 2+ hours of direct sun exposure.
Who should be careful
Avobenzone is rated moderate risk. Patch test on your inner forearm 48 hours before first facial use, especially if your skin reacts easily to new products.
