Is Hydroquinone safe?

Hydroquinone is prohibited in cosmetic products in the EU (CosIng Annex II), with documented concerns: cancer concern, irritation.

In plain language

A potent skin-bleaching agent banned from cosmetics in the EU and moved to prescription-only in the US. Unsupervised use risks paradoxical darkening (ochronosis). Beware of unregulated imported lightening creams.
