In brief
cosmetics and fertility: this page reviews Cumulative cosmetic product use (cocktail effect) (Overall cosmetic burden) โ documented mechanism, everyday exposure situations and possible alternatives. Level of evidence: Not studied.
- Where it's found
- Total number of cosmetic products used daily (cream, makeup, perfume, hair care, deodorant...), beyond each product considered in isolation.
- Suspected mechanism
- Each cosmetic product is assessed separately under regulation; actual exposure combines several products each containing a bit of different endocrine disruptors, whose combined effect is not measured as such โ the same blind spot as with food additives.
- Suggested alternative
- Reduce the total number of products used each day rather than seeking a single "perfect" product: that's the action that affects cumulative burden.
- Source
- ANSES, report on substance mixtures (2021) โ same reasoning applied to cosmetics.
