The lymphatic system is a complex network of lymph nodes, lymph ducts, lymph capillaries and lymph vessels that produce and transport lymph from tissues to the circulatory system.

Lymph begins as blood plasma that leaks from the capillaries of the circulatory system, becoming interstitial fluid, and filling the space between individual cells of tissue. Plasma is forced out of the capillaries and forced back in due to interactions of hydrostatic pressure and oncotic pressure. While out of the capillaries, the fluid mixes with the interstitial fluid, causing a gradual increase in the volume of fluid. Most of the fluid is returned to the capillaries. The proportion of interstitial fluid that is returned to the circulatory system is about 90%, with about 10% accumulating as excess.

The excess interstitial fluid is collected by the lymphatic system into lymph capillaries, and is processed by lymph nodes prior to being returned to the circulatory system. This excess is what can build up to cause fluid retention. Once within the lymphatic system the fluid is called lymph, and has almost the same composition as the original interstitial fluid.

Unlike the blood system which has a heart, the lymphatic system has no pump. Lymph movement occurs slowly with low pressure due to the pumping action of skeletal muscles. Like veins, lymph travels through vessels in one way only, due to valves. This depends mainly on the movement of muscles to squeeze fluid through them, especially near the joints. Exercise is encouraged in conjunction with Lumologie, as it promotes the movement of lymph. By being active you are less likely to have fluid retention. Thus, the signs of cellulite will be less obvious. Tight clothing can restrict lymphatic movement, reducing the removal of toxins, allowing them to accumulate.

As the circular path through the body's system continues, the fluid is then transported to progressively larger lymphatic vessels ending in the right lymphatic duct (for lymph from the right upper body) and the thoracic duct (for the rest of the body); both ducts drain back into the circulatory system at the right and left subclavian veins.

As lymph flows through the lymphatic system, it passes through lymph nodes. Lymph nodes are small organs of about 1-2 cm that filter large particles and remove foreign substances before lymph enters the veins. They may be oval, round, elongated, or bean shaped. Lymph nodes are usually found in subcutaneous tissue. Lymph nodes are often found in clusters, especially in the axilla, groin, sides of the neck, thorax and abdomen. The lymph nodes are located along the lymph vessels that lead from the tissue to the larger ducts.

Cellulite can be a result of poor lymphatic circulation. Sometimes when fat cells press against connective tissue, there is little room for lymphatic drainage and thus there is a build-up of fluids, fat and toxins. Fluid retention can appear to make the visible signs of cellulite more un-slightly.

Lumologie works at reducing the appearance of cellulite by stimulating lymph nodes and helping speed up the movement lymph and reduce 'fluid retention'. This has the effect of 'detoxification'.
