METHOD OF TREATMENT OF SKIN CONDMONS OF EYE LIDS
STATEMENT AT a: THE RICiTITS TO INVENTIONS MADE UNDER FEDERALLY
SPONSORED RESEARCH AND DEVELOPMENT
[00011 This invention was not made whit government support.
FIELD Of THE:INVENTION
100021 This invention relates to a method of the treatment eye lids with
non-
surgical blepharopla.sty by injection torevette.Skin tenting and upper eyelid
overhang and
lower lid laxity.
BACKGROUND
1Ø0031 Overhang:and tenting of the skin in the upper and lower lids of the
eyes are
uniqUe phenomena that can occur in individuals that are not of an advanced
age. The.
Skin in thenpPer: and tower lids of the eyes can be resistant to eye creams
for the
:reduction ofthe presentation of skin tenting, overhang and Way:: There are no
approved
or figoronsly evaluated non-surgical alternatives for treatment of these
conditions directly
at the 'So**, i.e. the. upper and lower lids. Surgical alternatives include
various forms Of
upper and lower lid blepharopIasties where incisions are made and fat is
surgically teased
out of candidates. All surgeries, however, are associated with the known risks
of
anesthesia, infection, bleeding, bruising, scarring, as well as the
possibility:Of:Nor
outcome and the expected discOnIfOrt and "doWn-time" for the patierit4
:Presently, there
are no injections for the upper and lOwer lids that reverse skin tenting,
laxitn overhang,
sag or puffiness. There has been hesitation in the market to date for
injections:into the:
tissue proximal to the orbits:of the eyes. Injections into this anatomical
sight Increase the
risk of causing blindness in the patient. None of the cosmetic substances
currently in the
cosmetic:injection market can be injected into the eye lids or the tissue
proximal to The
orbits of the eyes. There is a need in the market, therefore, for a non-
surgical alternative
to address *it) conditions of the eye lids which does not pose the risk of
causing
blindness. õA eitme solution however, could be used to successfully treat skin
eonditiOns
of thev.YellidS without the risk of causing blindness ill patients. The demand

surgical eye:Corr-000 iS: very highirt:0*vosmetic market.

100041Th spite of procedural risks, the growing appeal of cosmetic medical
treatment of
said PtoCedUres is a testament to the psychological importance of body image
and the
benefiCialoutcomes of these procedures, as perceived by the patients who seek
them.
However, the significance of a product that corrects signs of pen-orbital
aging with little
to no risk is significant.
BRIEF DESCRIPTION OF THE INVENTION
106051 The present in$41tWt:is directed to a method for the non-surgical
reduction of
Localized loose skin in the upper and. lower lids that is associated with the
normal aging
loss of the integrity of the derthiS-that supports the epidermis. The upper
lid tenting and
overhang and 16*g:11d:tenting, overhang and laxity can give the appearance of
one
looking tired when not in particular, a treatment for skin tenting, lid
laxity, sag and
overhang in the upper and lower lids Ofthe eyes with an aqueous solution of
citric acid
with a viscosity consistent with water at 26 to 25 C.
D.MAIUD DM:Rip-TM OF THE INVENTION
100061 The Invention provides a method fOr improvement of the tired look of
human skin
of the eye lids cOmprising administering citric acid or a salt thereof to a
patient in need
thereof; wherein the administering is a submitaneouS injection. The method
tightens
subcutaneous fat via strengthening of wall proteins:located in the hypodemils
of the skin
of the upper and IoWer eye lids to thereby enhance facial appearance. The
injection is,
for example, in the form of one or more large blebs or small boluses. The
method may
also include an additional step of measuring one or more improvements in the
appearance
of the skin with a measuring device. When the citric acid:or salt thereof is
placed in the
superficial plane or deep plains of sulxlermal fat, it causes skin tightening
by connective
tissue contractions, increase support of the subcutaneous tissue, and tensile
strength to
protein strands below the derinis. 'The citric acid or salt thereof may he

100071 The cOnlpositions, treatment schedules and methods of using said
compositions
discovered by the inventor effectively remove the effect of tenting or
impending tenting
of the upper and lower lids.. Generally speaking, tenting and impending
tenting and
tented skin ptosis of the upper and lower:lids of the eyes are a well-known
beauty
problems; problems that can progress to visual impairment if treatment to
reverse the
presentation of the tented and hanging skin is delayed. In addition, the
effect of
tightening tented and hanging skin with .subcutaneous injections repositions
fat and re-
compartmentaliz.es fatty tissue in its more anatOinically correct position.
[00081 Citrate constituted with isotonic water and dextrose can stimulate
elastin tensile
strength below the dermis and above and below the muscle to tighten skin,
decrease the
appearance of aging, and contour deficiencies, fine lines and wrinkles.
Citrate is found in
the serum of individuals. but also can be manufactured and processed,
[00091 The composition of the instant application is based on 100 volume
percent
calculations. In:particular, the composition of the instant application is
comprised of:
volume percent: 3.2 % sodiumeitrate buffer. In the preferred embodiment,
aPPr*irt1401Y-10911.410r$Odiurncitrate buffer is used. Citric acid, having the

trace electrolytes.
[00101 The invention also encompasses a kit. The kit includes the following
items 1),
sodium citrate powder. or a solution thereof, pre-loaded into a 20 cc
intravenous vial for.

sodium chloride, glycerol and trace electrolytes; and an injector device to
reconstitute'the
dry elements. The injector, mixes the Ingredients back and forth hetvveen two
10 cc
syringes until the formula is reconstituted to a dose of I Oml prior to
administration.
100111 The mixture should have a neutral pH priorloinjection. In addition, the
prepared
solution should exhibit the viscosity of water at 20.to 2C at the tiineof
injection.
OM The cOrtiPOsition attic instant application tor the subcutaneous reversal
of skin

competent
plastiesttrgeons, dermatologists or other medical doctors and their eligible
licensed staff.
Injections into the sub-dermal fat tissue in patients having skin tenting, sag
or lag of the
eye lids wilt tighten and thicken the subdermal fat bands and the hypodermis
thereby
reducing the appearance of fine lines, wrinkles, and pores of the eye lids.
190131 Formulations suitable for administration, conveniently comprise sterile
aqueous
solutions of the active ingredient(s). Preparations may be sterilized by, fOr
example,
filtration through a bacteria-retaining filter, by incorporating sterilizing
agents into the
compositions, by irradiating the compositions, or by heating the compositions.
Preparations can also be manufactured in the form' of sterile solid
compositions which
can be dissolved in sterile water or some other sterile injectable medium
immediately
before use. The formulation may be presented in Wit or multi-dose containers.

initial
treatment period involves up to 2 to 3 treatments involving an initial

usually two subsequent follow-up treatments, i.e. a follow-up treatment and a
follow-up

usually halted.
