The Science Behind Our Treatments

TECAR Therapy

Transfer of Capacitive and Resistive Energy (448 kHz Radiofrequency)

TECAR therapy delivers high-frequency radiofrequency energy into the tissues, producing deep therapeutic warming and stimulating cellular metabolism. This process enhances circulation, lymphatic drainage, collagen activity, and tissue repair while promoting lifting, firming, and improved skin quality.

Scientific Effects:
  • Increased microcirculation
  • Enhanced fibroblast activity
  • Improved lymphatic drainage
  • Collagen and elastin stimulation
  • Accelerated tissue repair

Pico Laser

Pico laser technology delivers ultra-short pulses measured in picoseconds (trillionths of a second). The extremely brief energy pulses create a photoacoustic effect that shatters pigment particles while stimulating collagen production with minimal thermal injury.

Scientific Effects:
  • Photoacoustic fragmentation of pigment
  • Collagen induction
  • Reduction of pigmentation and acne scarring
  • Skin rejuvenation
  • Improved texture and tone

Tattoo Removal

Q-Switched and Pico lasers selectively target tattoo pigments using the principle of Selective Photothermolysis, first described by Anderson and Parrish. The laser energy breaks pigment particles into microscopic fragments which are gradually removed by the body's lymphatic and immune systems.

Scientific Effects:
  • Pigment fragmentation
  • Progressive clearance by macrophages
  • Minimal injury to surrounding tissue
  • Gradual fading over multiple treatments

HIFU

High Intensity Focused Ultrasound

HIFU concentrates ultrasound energy beneath the skin, producing precise thermal coagulation points at selected depths. These microthermal zones stimulate neocollagenesis and tissue contraction.

Scientific Effects:
  • Collagen remodelling
  • SMAS tightening
  • Tissue contraction
  • Progressive lifting and firming

Plasma Fibroblast

Plasma energy creates controlled superficial micro-trauma, triggering the body's natural wound-healing cascade. Fibroblast activity increases, resulting in collagen remodelling and skin tightening.

Scientific Effects:
  • Controlled epidermal stimulation
  • Fibroblast activation
  • Collagen and elastin production
  • Tissue contraction

Fractional Radiofrequency (RF)

Fractional RF combines thermal energy with controlled tissue stimulation to remodel collagen and improve skin texture. Microthermal zones initiate healing responses while preserving surrounding tissue.

Scientific Effects:
  • Collagen remodelling
  • Skin tightening
  • Scar improvement
  • Reduced wrinkles and enlarged pores

CO₂ Fractional Resurfacing

Fractional CO₂ laser creates microscopic treatment zones within the skin while leaving surrounding tissue intact to promote faster healing. This controlled injury stimulates neocollagenesis and tissue regeneration.

Scientific Effects:
  • Epidermal renewal
  • Collagen synthesis
  • Scar remodelling
  • Improved wrinkles and texture
  • Skin rejuvenation

Cryolipolysis

Cryolipolysis selectively exposes fat cells to controlled cooling temperatures. Adipocytes are more sensitive to cold than surrounding tissues and undergo apoptosis (programmed cell death).

Scientific Effects:
  • Selective adipocyte destruction
  • Gradual fat reduction
  • Natural lymphatic elimination
  • Body contour improvement

Exosomes

Exosomes are extracellular vesicles containing signalling molecules, proteins, growth factors and messenger RNA. They facilitate intercellular communication and support regenerative processes.

Scientific Effects:
  • Cellular signalling
  • Collagen stimulation
  • Tissue repair support
  • Reduced inflammation
  • Enhanced healing

Microdermabrasion

Microdermabrasion provides controlled mechanical exfoliation of the stratum corneum, promoting epidermal renewal and improving the penetration of active ingredients.

Scientific Effects:
  • Increased epidermal turnover
  • Smoother skin texture
  • Improved luminosity
  • Enhanced absorption of skincare ingredients

Laser Hair Reduction

Laser energy targets melanin within the hair follicle according to the principle of selective photothermolysis. Thermal injury inhibits future hair growth while preserving surrounding tissue.

Scientific Effects:
  • Follicular destruction
  • Reduction in hair density
  • Progressive long-term hair reduction

Scar Therapy

Scar treatments stimulate controlled wound healing and collagen remodelling to improve texture, thickness and pliability.

Scientific Effects:
  • Collagen reorganisation
  • Improved tissue elasticity
  • Reduced scar thickness
  • Enhanced skin appearance

Exilis Elite®

Exilis Elite combines monopolar radiofrequency and targeted ultrasound energy to safely heat tissues at multiple depths. This thermal stimulation activates fibroblasts and promotes collagen remodelling while supporting body contouring.

Scientific Effects:
  • Collagen and elastin synthesis
  • Skin tightening
  • Tissue contraction
  • Body contour enhancement
  • Improved skin laxity

Key Scientific Principles

Neocollagenesis

The formation of new collagen fibres responsible for firmness and structural support.

Elastogenesis

The production of elastin fibres which contribute to skin elasticity.

Angiogenesis

The development of new blood vessels, improving oxygen and nutrient delivery.

Fibroblast Activation

Stimulation of the cells responsible for collagen and extracellular matrix production.

Selective Photo-thermolysis

The selective destruction of target structures using laser energy while preserving surrounding tissues.

Apoptosis

Programmed cell death—a natural biological process used in fat reduction and tissue renewal.

Lymphatic Drainage

The removal of waste products and cellular debris through the body's lymphatic system.
