Cos De Baha 2% Hydroquinone Brightening Serum

Hydroquinone bleaches your skin by decreasing the number of melanocytes present. Melanocytes make melanin, which is what produces your skin tone.

In cases of hyperpigmentation, more melanin is present due to an increase in melanocyte production. By controlling these melanocytes, your skin will become more evenly toned over time.

It takes about four weeks on average for the ingredient to take effect. It may take several months of consistent use before you see full results.
