What is BDDE?
Acronym. Definition. BDDE. Body Dysmorphic Disorder Examination (psychological assessment)
What is residual BDDE?
Residual, or unreacted, BDDE is considered nontoxic when it is <2 parts per million (ppm); therefore, the quantification of residual BDDE in the final dermal filler is mandatory to ensure the safety of the patients.
What is cross linking in fillers?
The cross-link is a process that allows linear hyaluronic acid molecules to be linked together, to obtain new structures consisting of several hyaluronic acid filaments with a higher molecular weight.
Is BDDE in fillers safe?
A literature search revealed that, in more than 50 studies conducted over the past 15 years in more than 9,000 patients, BDDE-crosslinked HA fillers have been reported to have a favorable safety profile and be generally well tolerated.
What is G Prime filler?
G prime – also written as G’ – is one of the key rheological properties of dermal filler. It refers to the viscosity and elasticity of the product. Essentially, it’s a rating that indicates how runny and pliable a filler is.
What is Profhilo?
Profhilo Treatment is a highly purified injectable hyaluronic acid skin booster. With special patented NAHYCO® technology, Profhilo functions to hydrate the skin from inside, like an internal moisturiser, and stimulates the production of elastin and collagen.
What is non cross linked hyaluronic acid?
Non-cross-linked hyaluronic acid ‘flows’ in the dermis, plumping up the skin and softening lines. Non-cross-linked HA fillers demonstrate excellent efficacy and tolerance results in sustainably improving the level of skin elasticity and complexion radiance.
What are the majority of HA products now Synthesised from?
Currently, large scale production of HA involves extraction from animal tissues as well as the use of bacterial expression systems in Streptococci.
Is Juvederm cross linked?
Juvéderm™ Ultra and Ultra Plus are smooth, malleable gels with a homologous consistency that use a new technology called “Hylacross™ technology”. They have a high concentration of cross-linked HAs, which accounts for its longevity.
What fillers are not cross linked?
Hyaluronic acid fillers are used for facial rejuvenation and are classified as non-cross-linked or cross-linked (monophasic mono- or polydensified).
What filler has the highest G prime?
Rheometric measurements at an oscil- lation frequency of 5 Hz showed Restylane and Perlane to have higher elastic modulus (G prime) than Prevelle Silk and Juvéderm Ultra Plus (Fig.
Can Profhilo go wrong?
When Profhilo is administered by someone who is appropriately qualified, trained and experienced the risks of something going wrong are very, very low. However, in inexperienced hands, Profhilo injections can be dangerous.
Can I inject Profhilo myself?
Answer: ABSOLUTELY NOT. Profhilo is developed using a patented technology resulting in hybrid cooperative complexes between high molecular weight HA and low molecular HA without the use of any chemical cross-linking compounds. These complexes increase the stability of HA to enzymatic and mechanical degradation.
What’s the difference between cross-linked and non cross-linked hyaluronic acid?
Native noncross-linked HA and chemically cross-linked HA show a rather modest proliferative effect and on fibroblasts only, whereas noncross-linked HA with added glycerol in high concentrations provokes a rather antiproliferative effect.
What is the difference between monophasic and biphasic fillers?
Cross-linked fillers are classified as monophasic or biphasic. Monophasic fillers consist of a homogeneous mixture of high- and low-molecular-weight HA, making their application easier. Biphasic fillers have cross-linked particles of HA dispersed in a non-cross-linked HA vehicle; therefore, the HA is heterogeneous.
Who invented hyaluronic acid?
biochemist Karl Meyer
In 1934, the German biochemist Karl Meyer and his colleague John Palmer isolated a previously unknown chemical substance from cows’ eyes. Because the substance contained uronic acid, one of the two sugar molecules found in large quantities in the vitreous humour, they named it “hyaluronic acid”.
Is hyaluronic acid Haram?
Also the vast majority of hyaluronic acid fillers do not contain anything which could be deemed haram i.e not permissible. It is important that you check this with your practitioner if you have any concerns.
What country is juvederm made?
Nestled in the beautiful, sleepy hamlet of Pringy in South Eastern France, 30 minutes’ drive south of Geneva, amidst breath taking views of mountainous terrain is the Allergan manufacturing facility.
Is it OK to use expired Juvederm?
Answer: Expired Juvederm We never use expired products on our patients. Expiration dates are put in place to indicate when a product may start to lose its efficacy.
How can we calculate the density of water?
To work out density: p = m/V
What does ‘density of water’ mean?
What Does Density Mean? (in Water) 1 Answers Anonymous answered It means 1g/cm3 or 1000kg/m3. Also the density of other liquid can be calculated using ; weight of liquid displaced / weight of water displaced.

How can you tell the density of water?
The density of liquid water is approximately 1.0 g/mL. The chart at right give the density in kg/m 3. Divide by 10 3 to get the density in g/mL. Let’s look at the density of water at 25 deg C and compare that to a higher temperature, 80 deg C. The density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is
