Imbalances in your gut bacteria can cause high estrogen levels—one of the major drivers of melasma.

The estrobolome, a particular group of gut bacteria excrete an enzyme (beta-glucuronidase) that converts estrogen into its active form for reabsorption. When estrobolome takes over, too much active estrogen is reabsorbed, which leads to increased estrogen [1].

If your melasma patches are on the forehead, gut health is something to explore. In traditional Chinese medicine (TCM), marks, redness and wrinkles on the forehead reflect imbalances in the gut.

There is plenty of evidence that melasma is an inflammatory skin condition. Studies have shown that patients have inflammatory markers in their blood and skin—indicators of an overactive immune system. In my book The Truth About Melasma, I share a wealth of information about the link between 

hyperpigmentation and inflammation and tell you what factors cause the immune system to be alert (including references).
