Chapter 7: Vascular & Pigmented Lesions Dual Flashcards
The green VP Dual hand piece emits two ranges of wavelengths:
- 535-680nm
2. 860-1200nm
Which chromophore does the VP hand piece target?
-both melanin and hemoglobin
What is essential to ensure an efficient and safe treatment?
When treating vascular and pigmented lesions, it is essential to tailor the spectrum in order to achieve an efficient and safe treatment
What happens at the 680-860nm spectrum of the VP hand piece?
- oxy&deoxyhemoglobin is relatively weak
- absorption of melanin is still somewhat significant
- therefore this band of spectrum is blocked to increase epidermal protection.
Describe the 535-680nm spectrum of the VP hand piece:
- this spectrum specializes in targeting vascular lesions
- it is also well absorbed by melanin, making this spectrum efficient in treating pigmented lesions
Describe the 860-1200nm spectrum of the VP hand piece:
- this spectrum covers medium absorption of melanin and hemoglobin, thus enhancing their heating
- since higher nm penetrates deeper, this band enhances heating efficiency of larger, deeper lesions
What skin types can be treated with the VP hand piece?
I-IV (1-4)
List some indications for VP treatment:
- spot treatment for both vascular and pigmented lesions
- may be used on vascular lesions around the nasal area
Describe how vascular and pigmented lesions will react after the treatment:
- vascular lesions will lighten or disappear
- pigmented lesions will darken and the progressively be sloughed away
Indications: Pigmented Lesions Diagram:
List the indications for vascular lesions of the VP hand piece:
-specializes in treating vascular lesions on skin type I-IV: —telangiectasia —erythema —rosacea & couperose —broken capillaries —poikiloderma —spider veins
What are VP treatments not indicated for?
*only effective on small, superficial blood vessels and not on large deep vessels such as leg veins
Treatment protocol diagram:
Pg 62-63 of manual
Contraindications:
Refer to chapter 3: the consultation
When seeking approval from a physician:
If unsure the physicians permission should be in writing and include:
- the patients specific condition
- details of the intended treatment
- permission to perform the treatment, taking into account the patients medical condition
- the permission should be documented in the patients records
What is the immediate response of the VP treatment?:
- immediate darkening of pigmented lesion
- immediate darkening or lightening of vascular lesions
Home care recommendations:
- immediate cooling
- sun protection SPF 30
- avoidance of exposure to sun, artificial tanning, dirt/debris
- cleaning and moistening during following days is important
- any redness and irritation should resolve in 24hrs
- tanning after treatment can result in enhanced regeneration, which may result in hyper-pigmentation
Treatment of Adverse Effects:
- treatment should be discontinued until treatment site has healed
- patient should return for examination after 3 weeks
- if results are observed after site has healed, increase skin type// select a darker skin type OR longer pulse duration and smooth pulse mode AND/OR lower fluence for the following treatment
- if adverse effects are observed without results, the patient should wait another 2-4 weeks and return for an additional examination
Treatment schedule and application:
- spot treatments with VP hand piece may consist of 1 treatment every 2-4 weeks
- remember healing may take 4-8 weeks depending on the age and condition of the skin
Describe proper application:
- always spot treat the lesion of choice first
- spot treat up to 2 times on each lesion adjusting perameters ONLY if necessary
- always asses the skin response to each pulse before continuing
- when mapping over the entire face be aware of the areas that have been spot treated
- if there is any erythema or edema present be cautious to avoid the area that was spot treated
