What you recommend for a liver detoxification?

Stop the bad habits: there's no magic bullet to detox a liver. but you can consider reducing any insults to it e.g. alcohol, otc meds.

No such thing: exists. Lots of fake /bogus/phony info out there about cleanses. What does cleanse mean anyway?! Is your liver dirty? The liver is the organ that actually does the "cleansing " of the body by metabolizing and detoxifying the nutrients and non nutrient substance (chemicals) we consume / take in. Be very wary of commercial products claiming to detoxify. You place your body at risk doing so.
