Skin Bio-Stimulation Techniques in Aesthetic Medicine: Part 1

Hyaluronic Acid: Deep hydration and plumping are strengthened, while collagen production is stimulated.

Hyaluronic acid is a naturally occurring component of the skin, playing a crucial role in its hydration and youthfulness. Its bio-stimulation mechanism is based on several synergistic actions:

1. Intense Hydration : Hyaluronic acid acts as a water reservoir, capable of retaining up to 1000 times its weight in water. When injected into the skin, it attracts and retains water, ensuring deep and long-lasting hydration. This increased hydration is essential to maintain the skin’s barrier function, its softness and radiance.
2. Tissue plumping : By retaining water within the skin tissues, hyaluronic acid generates a plumping effect. This makes treated areas appear plumper and fine lines and wrinkles appear reduced.
3. Collagen Stimulation : In addition to its moisturizing and plumping effects, hyaluronic acid can also act as an indirect trigger for collagen production. When the skin is well hydrated and plumped, it creates an environment conducive to the stimulation of fibroblasts, the collagen-producing cells. An increase in collagen production helps to improve the firmness and elasticity of the skin over time.

In short, hyaluronic acid exerts bio-stimulation by offering deep hydration, plumping up the tissues and promoting collagen regeneration. These combined effects help to revitalize the skin, minimize the visible signs of aging, and restore a more youthful, radiant appearance.

Poly-L-Lactic Acid: Promotes collagen regeneration for firmer, less wrinkled skin. Mechanism of action

Poly-L-Lactic Acid is a collagen stimulant used in aesthetic medicine to promote collagen regeneration in the skin, resulting in a firmer, less wrinkled appearance. Its mechanism of action is as follows:

1. Stimulation of Fibroblasts : Poly-L-Lactic Acid is injected into the deeper layers of the skin, where it comes into contact with fibroblasts, the cells responsible for collagen production. It acts as a stimulator, prompting fibroblasts to become more active and synthesize more collagen.
2. Gradual Collagen Production Process : Unlike other treatments that act immediately, Poly-L-Lactic Acid induces a gradual process of collagen production. Over time, fibroblasts stimulated by poly-L-lactic acid produce more collagen in the surrounding tissues.
3. Extracellular Matrix Renewal : Newly produced collagen strengthens the skin’s extracellular matrix. This improves its structure and firmness, which leads to a visible reduction in fine lines and wrinkles, as well as an overall smoother appearance.
4. Durability of Results : The stimulating effect of Poly-L-Lactic Acid lasts for several months. As new collagen forms, the improvements become more and more apparent. These results can persist for a year or more, depending on individual metabolism.

In summary, Poly-L-Lactic Acid works by stimulating fibroblasts to increase collagen production, which promotes the renewal of the skin’s extracellular matrix. This progressive action results in firmer, less wrinkled skin, with long-lasting, natural results.

Plant Extracts: Plant extracts stimulate cell regeneration and revive the skin.

Plant extracts used in aesthetic medicine act as skin bio-stimulation agents by stimulating cell regeneration and reviving the skin. The bio-stimulation mechanism of plant extracts is as follows:

1. Natural Active Ingredients : Plant extracts are rich in natural compounds such as polyphenols, flavonoids, vitamins, minerals, and other molecules that are beneficial to the skin. These active ingredients have antioxidant, anti-inflammatory, and regenerative properties.
2. Cell Stimulation : Plant extracts penetrate the upper layers of the skin thanks to their special formulation. Once applied, these extracts stimulate skin cells, including keratinocytes and fibroblasts, by activating different cellular processes.
3. Activation of Regenerative Processes : The bioactive compounds contained in plant extracts act on skin cells by activating regenerative processes. They can accelerate cell growth, promote collagen and elastin synthesis, as well as strengthen the skin barrier.
4. Improved Texture and Radiance : By stimulating cell regeneration, plant extracts help renew the top layer of the skin. This results in a smoother texture, a diminished appearance of spots and blemishes, and a more even, radiant complexion.
5. Soothing and Moisturizing Effect : Some plant extracts have soothing and moisturizing properties, which can help reduce inflammation and improve skin hydration. It can also contribute to a more radiant and revitalized look.
6. Skin Compatibility : Plant extracts are often chosen for their compatibility with the skin, thus minimizing the risk of irritation or adverse reactions.

In summary, plant extracts act as natural stimulators of cell regeneration by providing active ingredients that are beneficial to the skin. Their bio-stimulation mechanism promotes revitalized skin, improves texture and radiance, and can help reduce the signs of skin aging.

Peptides: These chains of amino acids stimulate the production of collagen and elastin.

The peptides used in aesthetic medicine act as skin bio-stimulation agents by stimulating the production of collagen and elastin. Here’s how peptides work to promote bio-stimulation:

1. Amino Acid Composition : Peptides are chains of amino acids, the building blocks of proteins. They are formulated to have a similar structure to the natural proteins found in the skin, such as collagen and elastin.
2. Cell Reception : Once applied to the skin or injected, peptides are absorbed by skin cells. Cells recognize peptides as biological signals, which trigger specific cellular responses.
3. Stimulation of Fibroblasts : Peptides act as messengers for fibroblasts, the cells responsible for the production of collagen and elastin. They send signals to fibroblasts to increase their activity and produce more of these structural proteins.
4. Increased Production : By activating fibroblasts, peptides stimulate the synthesis of new collagen and elastin molecules. These proteins are essential for maintaining the firmness, elasticity and youthfulness of the skin.
5. Skin Regeneration : Increased collagen and elastin production promotes skin regeneration. This can help to reduce the appearance of fine lines and wrinkles, improve skin texture, and restore firmness.
6. Gradual Effects : The effects of peptides can be gradual, as the production of new skin proteins takes time. As the weeks and months go by, the improvements can become more and more visible.

In short, peptides act as cellular messengers to encourage the production of collagen and elastin, thus promoting skin bio-stimulation. These proteins play a key role in maintaining the skin’s youthful and healthy appearance.

Growth Factors: Promote cell multiplication and tissue regeneration.

Growth factors are skin bio-stimulation agents that play an essential role in tissue regeneration and stimulation of cell multiplication. Here’s how growth factors work to promote bio-stimulation:

1. Signaling Proteins : Growth factors are proteins that occur naturally in the body. They act as communication signals between cells, triggering various cellular responses.
2. Cellular Response : When a growth factor binds to a specific receptor on the surface of a skin cell, it triggers a series of biochemical reactions inside the cell.
3. Cell Multiplication : Certain growth factors stimulate cell division, which promotes the multiplication of skin cells. This can help regenerate damaged or aging tissue and repair areas of skin affected by wrinkles, scars, or blemishes.
4. Collagen and Elastin : Growth factors can also encourage the production of collagen and elastin by fibroblasts. These proteins are essential for the firmness and elasticity of the skin.
5. Tissue Repair : By stimulating cell regeneration, growth factors contribute to the repair of damaged or weakened skin tissue, improving the texture and overall appearance of the skin.
6. Healing and Recovery : Growth factors play a crucial role in the healing of wounds and skin lesions. They help speed up the healing process by stimulating cell regeneration.

Growth factors are often used in aesthetic medicine to improve skin quality, reduce the signs of aging, and promote skin bio-stimulation. Their targeted action on cell multiplication and tissue regeneration contributes to achieving more youthful and revitalizing results.

Microcurrents: They stimulate blood circulation and cell renewal.

Microcurrents are a skin bio-stimulation technique that uses weak electrical currents to stimulate the skin and promote various beneficial effects. Here’s how microcurrents work for bio-stimulation:

1. Gentle Electrical Stimulation : The microcurrents used in skin bio-stimulation treatments are very weak and painless. They are usually imperceptible to the patient.
2. Increased Blood Circulation : The application of microcurrents to the skin causes a slight contraction of the underlying muscles. This can help increase blood flow to the treated area, which helps bring more oxygen and nutrients to the skin cells.
3. Improved Cellular Metabolism : Increased blood circulation and microcurrent-induced muscle activation can accelerate cellular metabolism. This promotes cell turnover and helps eliminate toxins.
4. Cell Regeneration : By stimulating metabolism and circulation, microcurrents can encourage the regeneration of skin cells. This can improve skin texture, reduce wrinkles and blemishes, and give a fresher, more youthful appearance.
5. Collagen Stimulation : Microcurrents can also play a role in stimulating collagen production. Strengthening collagen is essential for maintaining skin firmness and elasticity.
6. Absorption of Topical Products : During microcurrent treatment, special topical products may be applied to the skin. Microcurrents can help improve the absorption of these products, which can potentiate the results of bio-stimulation.

Microcurrent skin bio-stimulation treatments are non-invasive and can be used to improve the overall appearance of the skin, reduce the signs of aging, and revive natural radiance. Microcurrents work in harmony with the skin’s natural mechanisms to promote regeneration and vitality.
