Polynucleotide Theory First NameSurnameEmail Please pick one answer per question. Question 1 - Why wouldn't you use a blended HA and PN product in the peri-orbital zone? a) Due to Botox being better b) Due to the risk of haematoma c) Due to product licensing issues d) Due to HA being hydrophilic and the potential for the superficial placement to cause unwanted swelling Question 2 - What depth is an intradermal injection? a) At least 1cm b) A bevel up injection or 2-3mm c) A bevel down injection of 5mm d) More than 1mm but less than 5mm Question 3 - What angles are intradermal & subdermal injections given respectively? a) Intradermal 10-15 degrees, subdermal - below the dermal layer b) Intradermal >45 degrees, subdermal <75 degrees c) Intradermal 90 degrees, subdermal 10-15 degrees d) Intradermal 25 degrees, subdermal 90 degrees Question 4 - What is a fibroblast? a) A cell in connective tissue that produces melanin b) An osteoblast c) A cell in connective tissue which produces collagen & other fibres d) A malignant cell that must be destroyed Question 5 - How can you minimise discomfort when injecting polynucleotides? a) By using topical anesthetic, cold packs, a facial vibrating tool and changing the needle every 3-4 injections b) By using Clinisept prior to injection c) By avoiding patients who are sensitive to discomfort and sending them somewhere else d) By only using 30 gauge needles Question 6 - Polynucleotides are derived from? a) Salmon and tuna spermatozoa b) Trout and tuna spermatozoa c) Salmon and trout eggs d) Trout and salmon spermatozoa Question 7 - The biological effects of polynucleotides include? a) Increase of fibroblasts, melanocytes and glycosaminoglycans b) Reduction of redness & inflammation, stabilising of melanocytes, improved angiogenesis c) Reduction of elastase, collagen and other fibres in the skin d) Increase in trans-epidermal water-loss Question 8 - The longevity of a course of 3-4 polynucleotide treatments is how long? a) 12 months if the patient is under 45 years old b) 6-8 weeks for non-smokers c) It depends on genetics, age, lifestyle and environmental factors of the patient, but approximately 6-8 months d) It depends on the brand of polynucleotide Question 9 - What interval should there be (in general) between polynucleotide treatments? a) 4 - 6 days b) 2 - 4 weeks c) 72 hours d) 24 days Question 10 - Why are so many aesthetic treatments focused on increasing collagen production in the skin? a) Collagen is responsible for preventing skin cancer. b) Collagen is the main structural component of connective tissue, and its degradation is a pivotal process in the development, morphogenesis, tissue remodelling and repair of skin. c) Collagen prevents the skin from sweating. d) Collagen is the main structural component of connective tissue, and it will prevent pigmentation and discoloration of the skin.
