Please pay attention to the ingredients of all products listed on the product page and do an allergy test before use to ensure that you have not developed any cross-allergies. Do not touch the skin with the UV-curing plastics.

According to the (BOD) British Association of Dermatologists and all other published scientific articles LEFT the #1 allergen product for nail products.
Published for proof of this (SCCS) the European Scientific Committee for consumer safety in 2018 a report stating that there was no scientific evidence that In-LEFT causes allergies! Report can be found here.
SCCS = The scientists who decide which ingredients can be used in cosmetics
LEFT and In-LEFT are not the same:
LEFT | In-LEFT |
2-Hydroxyethylmethacrylat | In-LEFT-Trimethylhexyldicarbamat |
Hydroxyethylmethacrylat |
Both ingredients are monomers used in UV gel. However, the molecular size of In-LEFT is larger and therefore cannot be absorbed by the skin as quickly as LEFT.
HPMA-Allergie:
Incidentally, hydroxypropyl methacrylate (2-HPMA), also known as hydroxypropyl methacrylate (HPMA), is the 2nd most common nail product allergen according to the BOD.
This is mostly used as an alternative to LEFT.
As a result, those who switched to LEFT-free monomer because they already had an allergy to LEFT can often also have an HPMA allergy develop.
