Starting January 2026, Switzerland will enforce stricter limits on furocoumarins in cosmetic products, marking a significant regulatory shift. These naturally occurring compounds, commonly found in essential oils like bergamot, grapefruit, and lemon, are known for their phototoxic effects, which can lead to skin burns, pigmentation, and even genotoxicity when exposed to sunlight.
Under the new Swiss regulation, all cosmetics that remain on the skin and may be exposed to sunlight must contain less than 1 mg/kg (1 ppm) of furocoumarins. This limit will now apply not only to domestically produced goods but also to imported cosmetics, ending the previous leniency under the Cassis de Dijon principle 1.
This move sets Switzerland apart from the European Union, where furocoumarins are also restricted but with a narrower scope. In the EU, the 1 mg/kg limit applies only to sun care and tanning products, and furocoumarins are otherwise tolerated if they occur naturally in plant extracts 2.
The Swiss approach reflects a more precautionary stance, aiming to protect consumers from cumulative sun exposure risks across a broader range of products, including perfumes, creams, and aftershaves. Brands exporting to Switzerland will need to reassess formulations and ensure compliance well ahead of the 2026 deadline.
For cosmetic companies, this is more than a regulatory update, it's a call to innovate safer, sun-smart formulations.
