    Retinol at 0.5-1%. In my opinion, it’s more effective than 2% Hydroquinone (I tried both). 
    But it causes a lot of issues such as peeling, redness, irritation and many consumers wouldn’t like it. It is also very hard to stabilise and it’s very very prone to oxidation.
    If you are looking for something that wouldn’t cause a lot of problems AHAs is your best bet.

    The only thing proven save and effective to the satisfaction of the FDA is hydroquinone.

    Hydroquinone on black skin causes ochronosis on the long term, I’ve heard a few formulators here adding benzene and mequinol crystals plus fermented kojic dipalmitate to make a “cocktail ” that’s added to base cream at a ph of 5, but I’ve been reading on benzene and found it controversial but really most lightening agents are controversial. 

    I recently found out some bleaching creams contains actual bleach for washing clothes, hair relaxer, fungicide for killing weed and many shocking things

    Benzene is a recognised carcinogen. Strange that some people would add it to skin-lightening applications.

    @Majman - which formulators on here have advocated using benzene?  That is not a good idea but I don’t think I’ve ever read that here before.

    By “here ” I mean in my country, I’ve seen some add it and claim it’s healthier than using bleach and other toxic material or hydrogen peroxide.

    Ah, that makes more sense.  Text is sometimes an inefficient way to communicate.
