In fact, skin darkening caused by taking Hydroquinone can occur because this compound can’t really get rid of it, it only inhibits the production of melanin pigment in the skin.

When melanocytes die, their accumulation on the skin is inevitable (like any other dead skin cell). However, melanocytes will of course contain more pigment, so their accumulation on the surface of the skin can temporarily make the skin look darker than before. Depending on the severity of the pigment spots, hydroquinone-induced tanning can persist for a period of time (possibly several weeks) before users actually notice an improvement in their skin.

Although darkening from hydroquinone is normal and only temporary, if used improperly, hydroquinone compounds can still cause severe and long-lasting darkening and hyperpigmentation. Some common reasons for skin darkening from prolonged use of hydroquinone:

Hydroquinone’s skin lightening action is most effective when used in cycles, at least 4-8 weeks per cycle to give skin cells a chance to repair and repair, limiting resistance to its conditioning properties treatment of Hydroquinone;

 • Use a product containing poor quality hydroquinone: This compound works best when it is well-formulated, needs to be combined with other pigment-reducing ingredients and ingredients that soothe the skin and reduce irritation.
