Hyperpigmentation is a common, usually harmless condition in which patches of skin become darker in color than the normal surrounding skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.
What causes dark circles?
Oversleeping, extreme fatigue, or just staying up a few hours past your normal bedtime can cause dark circles to form under your eyes. Sleep deprivation can cause your skin to become dull and pale, allowing for dark tissues and blood vessels beneath your skin to show.
For the face use saffron gold on clean skin. You only need a small amount 1-2 drops, then let it absorb before applying another elixir to moisturise. This is a must. Our entire saffron range has been developed for hyperpigmentation issues. 
For cleansing the skin we highly recommend saffron complexion bar and saffron powder cleanser
For the body use saffron body bar daily and then moisturise with the saffron body oil.
