What does hydroquinone free mean?

"Hydroquinone free" refers to products that do not contain hydroquinone, a skin-lightening agent often used to treat hyperpigmentation. The term is significant for individuals who may be sensitive to hydroquinone or prefer to avoid it due to potential side effects, such as skin irritation or long-term use risks. Many alternatives aim to achieve similar results without the use of hydroquinone, making them appealing to consumers seeking safer options.
