#5: Collagen occurs in many places throughout the body. The 29 types of collagen have thus far been identified and described in literature. Over 90% of the collagen in the body, however, are of type I, II, III, and IV.
Collagen One: skin, tendon, vascular, ligature, organs, bone (main component of bone)
Collagen Two: cartilage (main component of cartilage)
Collagen Three: reticulate (main component of reticular fibers), commonly found alongside type I.
Collagen Four: forms bases of cell basement membrane
Collagen Five: Cells surfaces, hair and placenta
#8: Skin aging cannot be prevented. The following measures may help slow down and minimize the aging process.
Photothermal effect by IPL/Lasers + RF may improve lesions, but may also postpone skin aging due to collagen depletion by stimulating new collagen fibers.
#9: new collagen synthesis is on the structure of the mass of denatured fibers.
#12: Wrinkle reduction is based on collagen shrinkage and denaturation all over the dermis superficial and deep.
In order for it to be homogeneous, the heating should not be focused, but rather spread all over.
Since water and blood vessels are all over the dermis, they heat up by IR and RF and conduct the heat to the collagen fibers.
#14: Vector zones should be sized for 10-30 pulses: if they are too large (>30 pulses) the heat will not accumulate, if too small (<10 pulses) the heat will accumulate too fast with a burn hazard.
Vectors could be marked with a white eyeliner.
#17: The areas to be treated should not be too large (>30 pulses) so that the heat will accumulate.
At the same time, the area should not be too small (<10 pulses), as heat will accumulate too fast with a burn hazard.
Since the ST treatment is mild and safe, it is advised to do up to 50% overlap.
#27: As the body ages, the appearance and characteristics of the skin change. Collagen forms the structural network of our skin. As we age, it is believed that collagen and elastin deteriorate and cause the skin to become thinner and eventually sag.
#32: Tissue between the electode pins is heated and fibroblast stimulation is initiated = healing reservoir for low-downtime recovery.
#34: Heating/stimulation: Activatiand reversible damage, Metabolic effects (>42.5属C) collagenesis
Coagulation: Reversible to irreversible damage. Destruction of chemical bonds, proteins denaturizing
Metabolic effects skin tightening.
Ablation: Irreversible damage, evaporation of tissue. Metabolic effect skin resurfacing
