Hyperpigmentation by definition is the excessive pigmentation of the skin. Visually, it can be recognised as patches of the skin appear darker than the skin surrounding. It is a typically harmless condition, being a more aesthetic concern than anything else. A frustrating aesthetic concern, for sure. While the different types of hyperpigmentation may vary in origin, the science of why hyperpigmentation occurs stays relatively similar. Essentially, it appears due to an overproduction of melanin, stimulated by a number of different triggers such as UV exposure, hormones, genetics and even medical conditions and certain medications. The Secret uses intense, prescription ingredients that work tirelessly to fade existing pigmentation from the surface of the skin and prevent further pigmentation from forming.
