Hydroquinone for Hyperpigmentation

For those of you who have not heard of hydroquinone, hydroquinone is a topical skin bleaching agent that is commonly used for hyperpigmentation such as age spots, lentigines, melasma, post inflammatory hyperpigmentation and freckles.

It can come in:
-Creams
-Emulsions
-Lotions
-Gels
-Solutions
How does Hydroquinone work for Hyperpigmentation?
Hydroquinone for hyperpigmentation works to lighten the skin by blocking melanin production. It prevents the enzyme tyrosine to Dopa (dihydroxyphenylalanine) resulting in reduction of pigment.
The result is a reduction in the number of melanocyte which then reduces the transfer of melanin leading to lighter skin.

Whenever you are using products to help lighten hyperpigmentation whether it is:
-Retin A or Retinol
-Glycolic Acid or other AHAs
-Hydroquinone
