Leptin

Also called "satiety hormone", leptin is a digestive hormone that regulates appetite.

It influences the feeling of satiety, which tells the brain (hypothalamus) that the meal is over.

Its action is regulated according to the fat stores in the body.

It is secreted not only by white adipocytes but also in the stomach, in red skeletal muscles or in the bone marrow.

Lymph

Lymph is the whitish liquid that drips when you have a scratch that abrades your skin without going so far as to bleed.

This liquid is present throughout our body. It is found between our cells, our organs and our fascias. Its composition is similar to that of the cerebrospinal fluid that bathes our central nervous system.

It comes from the blood plasma that seeps through blood capillaries. Its colour is almost white because it does not contain red blood cells. On the other hand, it contains cells such as lymphocytes (lymph cells), which are part of the white blood cells that are responsible for protecting our body.

The lymph takes on waste and toxins that are in the body and evacuates them through a system of vessels, lymph nodes and channels that converge toward the heart. This is where the lymphatic fluid returns to the bloodstream, through which waste will be eliminated.

The lymphatic system transports a variable amount of lymph between 2 and 4 litres per day. It is interesting to compare this value to the nearly 5 litres of blood that the heart mobilises every minute. We understand that this liquid moves slowly, and that lymphatic drainage is a specific technique that requires slow and precise movements.

However, a properly performed lymphatic drainage can move as much lymph during a 45-minute session as it does during a whole day. The client can very clearly feel the movement of this fluid during the session.

It is important to make sure to stay close to the person when they stand up again after the session because they may feel a little dizzy.

It is also essential to offer them a drink. A large infusion with some draining plants will be the perfect drink.

Muscle relaxants

Drugs aiming at reducing the excessive intensity of muscle contractions that do not relax at rest alone and that can persist over very long periods of time.

They are used in painful contraction states that can have diverse origins: traumas, joint disorders or diseases, long-lasting postures, etc. This medical indication concerns people suffering from intense muscle tension, especially in the back and neck. 

Their effectiveness is discussed, in particular because they can lead to habituation or even dependence. There are two types of muscle relaxants. Some specifically target muscle activity and others, the muscle relaxation action of which is secondary, lead to a more general reduction in stress and/or anxiety (benzodiazepines, for example).

Muscle relaxants should exclusively be taken on medical prescription and for short periods of time. It is strongly recommended not to drive or do any activity requiring sustained attention after taking this type of medication, which may cause drowsiness.

In any case, consult your doctor.

Melanoma

A melanoma is a malignant cancerous tumor, quite rare but potentially serious, if it is not cured quickly.
It develops from pigment cells in the skin: melanocytes, the cells that produce melanin.

In 70 to 90% of cases, the cause is too much exposure to the sun and/or UV radiation, on a potentially high-risk skin type and with individual factors (e. g. genetics). Being exposed to the sun without protection in childhood increases the risk of developing melanoma.

Most skin melanomas appear on healthy skin. A melanoma initially appears as an irregularly shaped pigmented spot, which may look like a moleskin. It can also start from a pre-existing mole whose shape or color change can be observed.

If you see these types of skin signs on yourself or on the skin of regular customers, or not, the only effective way is to seek medical advice.

Organoleptic

Substances are called organoleptic if they are capable of stimulating our sensory receptors, whether those for sight, for smell, fpr taste, etc...

The visual appearance as well as the smell, taste or consistency of a food or a drink are organoleptic qualities.

Lucas Championnière

This device is named after its inventor, Dr. Lucas-Championnière.

It allows to spray on the face water vapour to which is added a lotion chosen according to the type of skin and the expected effect.

Depending not only on the distance between the device and the face, but also on the lotion chosen, the effects will be different:

  • a distance of more than 30 cm will give you a feeling of invigorating coolness;
  • placed at about 25 cm, the action will be emollient and hydrating on the surface;
  • a distance of only 15 to 20 cm will give you a feeling of warmth that will dilate the ostia (the pores of the skin).

This device is mainly used for aesthetic services such as facial care, skin cleaning before removing blackheads or after applying a mask. 

The use of this device requires significant vigilance not only in terms of safety for both the client and the practitioner, but also because of possible contraindications (heat, products).

Hygiene and maintenance of the device are essential for a professional and efficient use.
