Hi Crimbuki,
Most if not all of the common cream hair removals use as part of their formulation sodium hydroxide (caustic soda) low levels etc but. Sodium hydroxide is incredibly toxic to eyes. If you manage to alter a few chemical things with sodium hydroxide in your eye you will be blind, instantly. It is really good on body hair etc, but for Goddess sake DON"T USE SODIUM HYDROXIDE BY ITSELF, it is as powerful as any acid to burn you, sodium chloride is a very strong alkali reagent, similar to sulphuric acid but the other end of the pH scale. When in a cream it can be controlled for a few minutes, but remember hair removal creams are using chemicals to burn off your hair. Period.
If you want hair removal do it properly. If you can't afford laser or electrolysis buy an epilatior . I gave up and am having laser. I am 100000% pleased with the results.
Not all that expensive, but sometimes we have to save for our dreams
