Is Avobenzone safe on skin (left on)?
Personal care1 use researched6 sourced claims
Where it turns up: chemical uva filter in sunscreens. Detox My Life researched avobenzone under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.
Level by use and lens
| Use | Mainstream | Cautious (default) | Based | Concerns · favour · fringe |

| On skin, left on | Watch | Watch | Watch | 5 · 1 |
Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.
Safer swaps: the app's swap catalog has no entry tied to this ingredient yet. When you scan a product that contains it, the app suggests cleaner alternative types for that product; the swap categories list what the catalog covers today.

Sourced concerns (5)
ConsensusRestrictedconfidence 50%
The European Union approves avobenzone at up to 5% concentration and has no current restrictions, though it is under review for potential endocrine effects, and recent SCCS evaluations have led to reduced limits for some filters including avobenzone.
- Why here
- This is the current regulatory stance for leave-on sunscreen products in the EU.
- What would have to be true
- Dermal application of avobenzone-containing products at approved concentrations (up to 5% in EU).

ConsensusEndocrineconfidence 50%
Comprehensive toxicology reviews, including a September 2025 review, and regulatory bodies have found no effects on the estrogen, androgen, or thyroid systems at real-world human exposure levels, concluding that avobenzone does not disrupt the endocrine system at typical use concentrations. The EU Scientific Committee has not confirmed any risk to human health from typical topical use.
- Why here
- Comprehensive reviews of avobenzone's effects after dermal absorption from leave-on products indicate no endocrine disruption at relevant human exposure levels.
- What would have to be true
- Dermal application of avobenzone-containing products at approved concentrations (up to 3% in US/Canada, 5% in EU).
Sources the engine cites:
EmergingEndocrineconfidence 50%
Emerging research suggests avobenzone may have endocrine-disrupting properties, with studies finding it can affect androgen and progesterone receptors, though at lower potency than other chemical filters, and some cellular studies showing it can block testosterone effects at low doses in vitro.
- Why here
- Avobenzone is absorbed through the skin into the bloodstream from leave-on products, potentially leading to systemic effects.
- What would have to be true
- Dermal application of avobenzone-containing products, leading to systemic absorption.
Sources the engine cites:
EmergingIrritant · allergenconfidence 50%
Some individuals may experience skin sensitivity, irritation (redness, itching, burning sensation), or allergic/photoallergic contact dermatitis to avobenzone, particularly its degradation products, especially those with sensitive skin.
- Why here
- Direct contact of the leave-on product with the skin can cause irritation or allergic reactions.
- What would have to be true
- Dermal application of avobenzone-containing products, especially for individuals with sensitive skin or a history of allergies, and sometimes exacerbated by sun exposure (photoallergy).
Sources the engine cites:
EmergingEnvironmentalconfidence 50%
Avobenzone can accumulate in marine ecosystems, negatively impacting marine life and coral reefs, and has been detected in surface waters and wastewater treatment plants.
- Why here
- The ingredient is washed off the skin into aquatic environments from leave-on sunscreen products.
- What would have to be true
- Dermal application of avobenzone-containing sunscreen, followed by water exposure (e.g., swimming).

In its favour (1)
ConsensusClearedconfidence 50%
The FDA classifies avobenzone in the "insufficient data" category for Generally Recognized As Safe and Effective (GRASE) status, not due to findings of unsafety, but because manufacturers have not submitted all requested safety data, though it is approved for use up to 3% concentration in the US.
- Why here
- This is the current regulatory stance for leave-on sunscreen products in the US.
- What would have to be true
- Dermal application of avobenzone-containing products at approved concentrations (up to 3% in US).

Not researched here
The engine has no dossier for avobenzone when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
