This is a multifunction product, because it is useful as a base, top, strengthener and preventing nail-biting.
If applied before nail polish, it makes the polish last longer.
If applied after nail polish, it accentuates its brightness with an extraordinary glossy effect.
If used regularly on clean and dry nails, it protects brittle nails that exfoliate or chip easily.
Its rather bitter taste prevents nail biting.
In addition, it is enriched with a special additive derived from methionine, an amino acid that is part of the keratin chain of the nails. It is recommended for fragile fingernails that split or chip easily; when used regularly on clean, dry nails, it is an excellent protection against damaging agents.
