Q-SWITCH LASER

The length of the laser session and decision to use anaesthetic can vary depending on the condition being treated.

For photopigmentation, melasma, skin toning and skin staining anaesthetic is generally not required. For some birth marks and in certain other circumstances Dr Scott may decide to use either a topical or injectable anaesthetic.

Depending on the settings chosen, cold air may be used to cool the skin during treatment which protects the epidermis (the outer layer of the skin). Loud ‘snapping’ sounds may be heard during the treatment – a result of the photoacoustic effect that is unique to short-pulse lasers. At higher energies the sensation of a rubber band flicking the skin may be felt, followed by a slight sting & warm sensation. This generally subsides with the application of a soothing gel post- treatment.

Following the treatment session, the skin may be red, a little swollen and occasionally bruised. This generally lasts between 2-10 hours, depending on the settings used. The skin may feel rough & be more sensitive for 3-5 days – it is important to follow your post-treatment recommendation during this time. Pigmentation usually appears darker for 7-10 days, following which it begins to lighten.

Areas on the face tend to recover quicker than the neck & body. If treatment on the neck, hands or other part of the body is required, recovery may be longer than indicated above.

Recovery following treatment for birthmarks can be more significant and highly variable – Dr Scott will explain what to expect for your specific concern during your consultation.

Side effects associated with laser treatment are uncommon, but possible. These include:

- Infection of the treated area

- Unwanted pigmentation changes – darker (hyperpigmentation) or lighter (hypopigmentation). These changes may be temporary or, rarely, permanent.

- Burns to the skin, which may cause blistering, scabs or scars (rare)

Eye protection (provided) is required at all times during a laser treatment, as damage to the unprotected eye may otherwise occur.

The number of treatment sessions varies based on a person’s individual skin, the source of their pigment and their response to early laser sessions. As a general guide:

- Freckles & solar lentigines: 2-4 sessions

- Skin toning: 4-6 sessions

- Birthmarks & skin staining: 2-8 sessions

- Melasma: 4-6 sessions, followed by maintenance sessions (the number of which are guided by pigment recurrence rate)

It’s useful to think of in-clinic laser treatments like visiting a personal trainer. Even though you may visit once a month, what you do at home counts more - it’s super important to train in the interim to see results!

When undertaking laser treatment for pigmentation Dr Scott usually designs and prescribes a bespoke prescription skincare regimen to ensure the best results possible. The cream(s) are designed for your skin and compounded by our specialist pharmacy - specifically for you. You’ll receive information following your consultation on what’s in your formulation and how to use it in a safe & effective way.

Absolutely. Sun protection is always important for our skin, but is of paramount importance when undertaking laser treatments for pigmentation.

We should all wear a broad-spectrum sunscreen daily - even if working from the office (as UVA radiation passes through glass, creating damage to our skin even when indoors). We understand that many sunscreens are unpleasant to wear on a daily basis, and sunscreen preference is very individual - feel free to have a chat with us for some suggested sunscreens to try that are designed for daily wear (including under makeup!). Protective clothing (hats, long sleeves, sunglasses etc) and knowing when the UV index is high is useful for

minimising sun damage and further pigmentation - check out the SunSmart app (developed by the Cancer Council), which is a great tool to understand when the UV index is high in your area.

There are many causes of dermal pigmentation, some of which respond better to laser treatment than others. To assess whether Q-switch laser may be of benefit for your specific situation, Dr Ellis will complete a comprehensive assessment. During your consultation you will learn what may be contributing to your individual concerns, as well as what treatment options are reasonable for you to consider.
