Cumulative cosmetic product use (cocktail effect)
Overall cosmetic burden
Evidence level : Not studied BathroomMechanism : Hormonal disruption burden
🔴 The exposure is real and common, but no serious study has measured its effect on human fertility. It remains unknown.
- 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 — 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) — same reasoning applied to cosmetics.

Including a factor does not mean it causes infertility: it is simply worth monitoring, depending on its level of evidence.
