Which ones do we use?
At L’Oréal, we only use 4 ingredients at the nanometric scale.
- Nano titanium dioxide
- Nano zinc oxide
- Nano carbon black
- Nano silica
What are they used for?
Nanoparticles are used safely for their unique cosmetic benefits:
Increase the level of sun protection and avoid white marks on skin (nano titanium dioxide & nano zinc oxide)
Deliver the best product texture and provide a matte finish on skin (nano silica)
Increase the black intensity in mascara (nano carbon black)
Why are they questioned?
Nanoparticles are subject to controversy due to their possible impact when applied on damaged skin, and their potential toxicity in the event where they are ingested or inhaled (due to their small size).
Nanomaterials are deemed safe for cosmetic use by the EU’s Scientific Committee for Consumer Safety (SCCS).

Why and how do we use them?
We only use nanoparticles when they enhance product performance: provide a higher quality and comfort, a better texture, or a greater colour intensity.
The nanoparticles we use are safe, and their safety is confirmed by the SCCS.
We use nanoparticles in products that are not inhaled. They are not used in aerosols.
When nanoparticles are present in our cosmetic products, we always inform our consumers in a transparent way by labelling nanoparticles as [nano.] in the ingredients list.
We apply the highest regulations everywhere in the world where our products are sold.
