Chapter 7: Vascular & Pigmented Lesions Dual

Question 1

The green VP Dual hand piece emits two ranges of wavelengths:

Answer 1

1. 535-680nm

2. 860-1200nm

Question 2

Which chromophore does the VP hand piece target?

Answer 2

-both melanin and hemoglobin

Question 3

What is essential to ensure an efficient and safe treatment?

Answer 3

When treating vascular and pigmented lesions, it is essential to tailor the spectrum in order to achieve an efficient and safe treatment

Question 4

What happens at the 680-860nm spectrum of the VP hand piece?

Answer 4

• oxy&deoxyhemoglobin is relatively weak
• absorption of melanin is still somewhat significant
• therefore this band of spectrum is blocked to increase epidermal protection.

Question 5

Describe the 535-680nm spectrum of the VP hand piece:

Answer 5

• this spectrum specializes in targeting vascular lesions

- it is also well absorbed by melanin, making this spectrum efficient in treating pigmented lesions

Question 6

Describe the 860-1200nm spectrum of the VP hand piece:

Answer 6

• 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

Question 7

What skin types can be treated with the VP hand piece?

Answer 7

I-IV (1-4)

Question 8

List some indications for VP treatment:

Answer 8

• spot treatment for both vascular and pigmented lesions

- may be used on vascular lesions around the nasal area

Question 9

Describe how vascular and pigmented lesions will react after the treatment:

Answer 9

• vascular lesions will lighten or disappear

- pigmented lesions will darken and the progressively be sloughed away

Question 10

Indications: Pigmented Lesions Diagram:

Answer 10

Question 11

List the indications for vascular lesions of the VP hand piece:

Answer 11

-specializes in treating vascular lesions on skin type I-IV:
—telangiectasia 
—erythema
—rosacea & couperose
—broken capillaries
—poikiloderma
—spider veins

Question 12

What are VP treatments not indicated for?

Answer 12

*only effective on small, superficial blood vessels and not on large deep vessels such as leg veins

Question 13

Treatment protocol diagram:

Answer 13

Pg 62-63 of manual

Question 14

Contraindications:

Answer 14

Refer to chapter 3: the consultation

Question 15

When seeking approval from a physician:

Answer 15

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

Question 16

What is the immediate response of the VP treatment?:

Answer 16

• immediate darkening of pigmented lesion

- immediate darkening or lightening of vascular lesions

Question 17

Home care recommendations:

Answer 17

• 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

Question 18

Treatment of Adverse Effects:

Answer 18

• 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

Question 19

Treatment schedule and application:

Answer 19

• 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

Question 20

Describe proper application:

Answer 20

• 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
