Much of the discoloration will fade or disappear once hormones stabilize and you stay out of the sun. It’s the portion of the Moon that is permanently turned away from the Earth.

The longest of these UV rays that reach the Earth’s surface are called UVA rays. The Moon that we see is very bright from the sunlight reflecting off it. The patches gradually fade over many months.

The most important factor in the development of melasma is exposure to sunlight. The larger part of a shadow, less dark than the umbra, is called the _____ During the moon's first-quarter and third-quarter phases, the line between Earth and the sun … It has one of the largest craters in the Solar System, the South Pole–Aitken basin.

Rarely, these dark patches may appear on other sun-exposed areas of the body. The term Black Sun (German Schwarze Sonne), also referred to as the Sonnenrad (the German for "Sun Wheel"), is a symbol of esoteric or occult significance. The Moon is tidally locked to Earth, so it rotates only once every 29.5 days—one complete orbit of Earth. An object that has albedo of 0 does not reflect sunlight and is perfectly dark.

The best way to prevent melasma is to limit skin exposure to the sun. It typically occurs on the face, particularly the forehead, cheeks and above the upper lip. They are equipped with sensors that measure the speed, direction and composition of the solar wind; receivers that pick up radio emissions from explosions and shock waves in the sun's atmosphere; telescopes that image the solar surface and all the tempests that rage there; and coronagraphs to monitor events in the sun's outer atmosphere. The far side barely has any. Subscribe to Drugs.com newsletters for the latest medication news, new drug approvals, alerts and updates.
