This recent field is a real revolution in cosmetic surgery to treat skin and skin aging in a completely natural and sustainable way. It is one of Dr. Quinodoz’ main recent passions. Regenerative medicine, also known as regenerative medicine or surgery, is “a field of research and clinical applications focused on the repair, replacement or regeneration of cells, tissues or organs to restore impaired function” of the human body. Regenerative medicine (or surgery) is applied to many fields, such as cosmetic surgery, degenerative diseases, trauma or congenital malformations, notably through the use of stem cells (see link below).

The stem cells or “mother cells” that interest us in plastic and aesthetic surgery are present around the fat cells in certain special areas of the body. These stem cells have the unique ability to transform into any other cell line depending on local needs or stimulation. Stem cells, if injected into the skin, can be transformed into all of its components, such as elastin, collagen, etc. Moreover, by a mechanism that is still not well understood, the injection of stem cells can reduce brown spots associated with aging. In practice, in the operating room, the cells are taken from the fat of certain specific areas of the body by gentle liposuction, without great pressure, using a mini cannula connected to a syringe.

The fat removal and stem cell injections are normally performed under
anesthesia with sedation on an outpatient basis, but often during a similar blepharoplasty or facelift procedure in order to take advantage of the anesthesia. The fat sample is then worked on: first we mechanically fragment the fat cells by moving back and forth between two syringes connected by two microfilters in order to emulsify and selectively destroy them. The stem cells are located around the fat cells but are very small in size, so they pass through the filter without being damaged and it is only the fat cells that are affected and destroyed and are separated from the stem cells.

The stem cells are then injected all over the face and in certain parts of the body using a mesotherapy-type device, but in a sterile manner. This technique makes it possible to use our own body cells to rejuvenate the skin and remove brown spots related to aging. This treatment is totally natural since everything comes from the patient himself without any added chemicals.

The isolation of stem cells by chemical means is prohibited.

LINK FOR STEM CELLS

In cell biology, a stem cell is an undifferentiated cell capable of both generating specialized cells by cellular differentiation and maintaining itself in the organism by symmetric or asymmetric division. Stem cells are present in all multicellular living beings. They play a central role in the development of organisms as well as in the maintenance of their integrity throughout life.

The study of animal stem cells is a very active field of research, particularly because of their applications in medicine. This field of study has recently undergone a rapid expansion with the development of techniques allowing the generation, in culture, of pluripotent stem cells from any cell of the body, these stem cells are called induced[1]. However, stem cells are also present in other forms of multicellular life such as in the meristems of plants.

EXOSOMES

Exosomes are small extracellular vesicles, around 30 to 150 nanometers in diameter, produced by almost every cell in the body. They are essential for cellular communication, as they contain various molecules such as proteins, lipids, RNA and even DNA, which they can transport from one cell to another.In aesthetic medicine, particularly for facial skin care, exosomes are exploited for their regenerative and reparative properties. They can promote wound healing, tissue regeneration and reduce inflammation, making them useful for treatments such as skin rejuvenation, wrinkle reduction, and improving skin elasticity and texture.These exosomes can be obtained from a variety of sources, including stem cells, and are often applied topically or injected into the skin. They work by stimulating skin cells to repair and regenerate themselves, which can lead to improved skin appearance and health.However, it’s important to note that exosome research, while advanced, is still in development, and their use in aesthetic medicine continues to evolve with new discoveries.

Exosomes are small vesicles that facilitates the transport of important substances between cell. Their content is essential, and it’s crucial to ask your doctor about the type of exosome concerned. In fact, the term “exosome” is generic, a bit like “red wine”, which covers various types of wine. Although the container, often made of glass, is identical, the contents can vary from the best to the worst. It’s important not to neglect this aspect when it comes to your health!
