If soft tissue fillers are used for deeper rhytids or facial volume replacement the procedures should be performed two weeks to one month prior to peehng or resurfacing. The deeper fillers in subcutaneous tissue and below are too deep to be affected by peel or laser, but superficial dermal fillers should be performed after resurfacing. 

An organic material which occurs in the woody tissues of plants. It is a by-product in the preparation of cellulose for the manufacture of paper, rayon and the cellulose plastics, and its use has been proposed as a reinforcing filler for rubber. 

Starch is extensively used due to its adsorbing properties. In dissolved form, it is used as a skin emollient and as an antidote for iodine poisoning. Other applications include the use as a tablet filler and binder and disintegrant. Sterilized starch is used as a lubricant for surgeon gloves. Unlike talc, it is completely adsorbed by body tissues. Soluble starch is prepared by treating commercial potato starch with dilute hydrochloric acid until it forms an almost clear solution in hot water. 

The experiments documented in Tables 5 and 6 use confluent monolayers of pure bovine aonn endothelial ceiis thar were grown in tissue culture petri dishes, then seeded at high concentration on collagen-coated polycarbonate filters (pore diameter 0.8 im). The fillers were fitted onto millipore filter holders placed in a buffer compartment with separate access to both sides of the Biter... 

Block terpolymers prepared by Cheng [5] consisting of poly(A-isopropyl acrylamide-b-polyethyleneoxide-b-A-isopropyl acrylamide), (II), were effective as thermally reversible gels and used as subcutaneous implants, joint or tissue spacers, and biological filler for wrinkles or cosmetic implants. Methacrylamide analogues were prepared by Gutowska [6]. 

As the talc, cornstarch, and other insoluble tablet fillers embolize to the lungs, they become trapped within the pulmonary tissues and eventually cause pulmonary hypertension. This leads to the development of collateral vessels that allow part of the venous retmn to bypass the lungs and enter the left side of the heart, where the particles are further embolized to the eye and other organs of the body. The presence of talc particles in the eye indicates that substantial foreign body damage has occurred in the lungs.

The natural permeabilities of polymers vary over a wide range and this widens the choice, provided one can select a polymer which is compatible with the tissues with which it comes into contact. Once a polymer has been chosen that gives a flux of drug sufficient to provide adequate circulating levels, use of fillers and plasticisers can give fine control of permeability (Table 8.7).
