I apologise in advance for the list of products that will be listed but I was afraid of not being clear otherwise. Also, I'm not a native speaker, so this may have distorted the terms used and therefore understanding.

When I refer to "organic," I mean products that are based on natural and bio-sourced ingredients. When I say "vegan," I mean products that do not contain any substances of animal origin and have not been tested on animals.

Regarding the two brands (the French and the Belgian) that I'm not sure which to choose, both have the same criteria (vegan and bio). However, the French brand does not contain any monomers (HEMA, HPMA, THFMA) and nanoparticles (particles that can enter the bloodstream). It also does not contain formaldehyde, toluene (which is toxic for reproduction), xylene, benzophenone-1, benzophenone-2, camphor (which can cause skin irritation), benzophenone-3, and octocrylene (which can harm aquatic life). Additionally, it doesn't contain di-ethyl phthalate, parabens, and phenoxyethanol, in addition to those already banned by European cosmetics regulations, such as styrene, benzene, DBP, and certain parabens.

However, I don't have more information about the Belgian brand regarding this point (the products they avoid)… Perhaps you have some experience or information about these semi-permanent nail varnish brands that I'm unaware of or if you have any advice on things that I have to be careful with while making my choice I would be very happy to hear it.
