V Laser

The V Laser is a KTP laser used for vascular and pigment removal. A KTP laser is a solid-state laser that uses a potassium titanyl phosphate crystal to produce a laser wavelength of 532 nm.

The Science

The KTP laser works on the principle of selective photothermolysis.

This means that the selected wavelength of laser light (532 nm) is highly absorbed by the target structure (chromophore) and less absorbed by surrounding tissue.

The skin chromophores targeted by the KTP laser are melanin (pigment) oxyhemoglobin (red blood cells) and red tattoo pigment, making it effective in treating pigmentation and vascular lesions.

When KTP laser light hits the skin, it is reflected, transmitted, or absorbed.

Absorbed light energy is converted to thermal energy (heat) by the intended targets (chromophores), thereby destroying the target cells.

What it treats

Superficial port wine stains (vascular malformations)
Acquired cutaneous vascular lesions, including telangiectasia, cherry angiomas, and poikiloderma of Civatte
Rosacea
Freckles
Epidermal melasma
Sun damage

Suitability

V Laser is NOT suitable for individuals who meet one or more of these criteria:

Dermal melasma
Low contrast pigment (little colour differentiation between the baseline skin tone and the pigmented lesion)
Patients requesting pigment treatment to large surface areas
Sunburnt, sun-exposed, or fake-tanned skin
Pregnancy and breast feeding
Active cutaneous infections (bacterial and viral)
Using light-sensitizing medications
Recent Roaccutane use
Recent injectable treatments with botulinum toxin, dermal fillers and threads (2 weeks)
Recent skin or laser treatments (2-4 weeks)

What's Involved

The patient will wear protective goggles throughout the treatment. The treatment involves placing a handpiece against the skin surface and activating the laser. Many patients describe each pulse as feeling like the snapping of a rubber band against the skin.

Topical anesthetic or forced air cooling may be applied to the area, but it is not necessary if there is a cooling system.

Immediately following treatment, a cool pack may be applied to soothe the treated area.

Pre and Post Procedure Care

Pre-Procedure Care:

2-4 weeks prior to having a laser treatment, we recommend that the skin is primed with active ingredients such as depigmentation agents like hydroquinone, exfoliating agents like BHA or AHA, vitamin A, and vitamin C. This reduces the risk of post-laser complications like post-inflammatory hyperpigmentation (especially in patients with darker skin types), maximizes peel outcomes, and assists in speeding the healing time.

Post-Procedure Care:

For the next 5-7 days, avoid using moisturizers or lotions containing active ingredients such as retinol, glycolic acids, perfumes, and colors. Please use the moisturizer recommended to you for 3-7 days or until your skin is no longer sensitive. Thereafter, continue with your usual moisturizers unless advised otherwise. Your skin will be a little more sensitive to the sun, so keep sun exposure to a minimum. Please wear a hat and sunscreen daily. This should be a regular routine for you anyway! Apply foundation as you wish. Slight crusting and/or scabbing in particular areas may develop. If so, please do not rub or pick the skin as this may lead to scarring.
