Guest guest Posted July 18, 2002 Report Share Posted July 18, 2002 Hi Group: I dont know if i am not getting the question but to my knowledge lasers do not have afinity to an artery or a vein, the energy gets absorved by Hemoglobin wich acts as a cromophore of course the succes or the irreversable destruccion of the vessels depends on wavelenght,parameter,pulse-exposure,duration and fluence (selective photothermolisis) the choice of the wavelenght dependes in the capacity of the vessel to absorve the energy in wich hemoglobin is targeted, in case of IPL also melanin is targeted, heat is produced by every zap and absorved by the target, the wall of the vessel coagulates with the heat and breaks down like any protein (desnaturalization) it is not like an Hemangioma in wich there is a perforant vessel wich should be destroyed, besides lets suppose that we can see depper vessels how are you going to feed or nuirish the surrounding dermal vascular dermal tissue because the epi is avascular not the dermal layers, i dont understand? the conective tissue that sorrounds the capilars is weak but not the capilars if both tissues are conective why one is weak and the other is not. Matija or Majorie or all! why Dr Sy chooses cimetidine to avoid flushing and not any other h2 blocker since cimetidine has many interaccions and may cause ginecomastia in men. Adalactone is used in rosacea not that much because of its antiandrogenic properties but because it lowers the sensibility to noradrenaline, sometimes it works sometimes it doesnt just stop it. Mazzy hace mucho no te escucho, que mala onda nadamas encuentras tus suplementos y te olvidas de los amigos escribeme para saber como estas y te mando un abrazo. Marie sorry i had been very busy i respond as soon as posible, take care you all and have a great day, for those with seborrheicdermatitis dis you try ketoconazol or naftifine can be very helpfull.
