Those problem dark spots, that are associated with getting older, could be a frustrating reminder of the aging process, although younger folks get them too. They’re linked to hormone therapy medication and pregnancy, as well as aging. Technically called “melasma”, the condition affects over five million people, mostly women. It’s caused by out-of-control pigment formation. Contrary to conventional wisdom it is not the result of sun exposure, but rather excess estrogen and the stress hormone cortisol.

One of the best ways to lower cortisol and keep skin clear and bright is to maintain stable blood sugar, which is always a good idea. Don’t indulge in high carb processed foods, especially desserts, cereals and snacks. Using cortisol balance and nutrients, like vitamins C and E and the mineral selenium, can be helpful. Likewise, use the B vitamins, lecithin capsules and pregnenolone. To balance estrogen, use progesterone cream, supplement with essential fatty acids and iodine, improve bowel function with fiber and probiotics.

Topically you can lighten dark spots with vitamin C and retinol. Alpha hydroxy acid toners can be effective, as can chemical peels done by a skincare professional. The drug hydroquinone works to lighten skin, but it’s pretty toxic stuff, and it’s probably best avoided. Although if you’re desperate, you might want to use it temporarily.
