Thanks for posting your query. There are many skin lighteners. The stronger ones contain hydroquinone
. The formula you have mentioned contains a mixture of various ingredients. It should be good.
But, do remember that any lightening agent has to be used as long you want a good effect. All treatment are reversible which means if you stop medications you will go back to your original color in six months. Hence it is better to choose lighter and medium potent agents only.
Do remember to avoid sun exposure or to take an umbrella always when you go out in sun light.
