What is it?

The Gemini is an FDA-approved, state-of-the-art laser system providing treatment for a variety of vascular and benign pigmented lesions.

The Gemini has two wavelengths. There is the KTP (532nm wavelength) that treats vascular lesions and the Nd:Yag (1064 wavelength) which treats deeper vascular structures and reduces unwanted hair on the face and the body.


What Conditions Does Gemini Treat?

  • Angiomas – small “drops of red” that can appear anywhere on the body and are often more common on the chest.

  • Benign pigmented (brown) skin lesions

  • Haemangiomas

  • Facial telangiectasia (“broken” capillaries commonly found on the nose and cheeks).

  • Leg veins (small veins on the legs)

  • Rosacea – treats diffuse redness to reduce facial flushing

  • Spider veins on the face, legs and ankles

  • Sebaceous hyperplasia (dilated oil glands)

  • Venous lake (dark blue vascular lesion usually on the lip, but sometimes on the face or the ear).

How Many Treatments are Needed?

 The number of treatments depends on various parameters, including the size, thickness and colour of the vascular or pigmented lesion(s). Since individual results vary, ask your laser dermatologist about your specific condition.

Are There Any Other Laser Treatment Options Available for These Conditions?

Yes, there are numerous laser treatments available for skin conditions, depending whether it is vascular or pigmentation. The challenge associated with laser treatments is tailoring the treatment to precisely match the patient’s skin condition. The Skin Specialist Centre is unique in that it provides the widest range in New Zealand of lasers and light devices for the management of pigmentation and vascular conditions.

What are the Possible Side-Effects?

Although many patients report few, if any, side-effects, those most commonly noticed are slight reddening and local swelling of the treated skin. Some patients may experience bruising and, in rare instances, blistering may occur.

  • Soreness and redness – in rare instances, soreness and redness may occur.

  • Swelling – this is common, especially on the upper cheeks and forehead, and usually subsides within a few days. A cold pack is applied following treatment to limit swelling. Sleeping more upright for extensive procedures is recommended for the first two nights to reduce swelling.

  • Pain – there may be some pain during the procedure, but this is significantly reduced with the use of topical anaesthesia.

  • Pigment loss – in the majority of patients, the risk of pigment loss would be small.

  • Hyperpigmentation – there may be an increased risk of pigmentation as the healing reaction occurs in darker-skinned individuals. If this occurs, the increased pigmentation (post-inflammatory hyperpigmentation) usually fades over a period of months and may rarely require the use of a bleaching cream.

  • Scarring – given the specificity of the laser, there is a very small incidence of scarring.

  • Incomplete result – the condition being treated may not be completely or effectively treated with one treatment and may require a further session or sessions of the same or a different modality.

Recovery Time

There is usually significant swelling for the first 24 – 48 hours and it is recommended that patients have at least two days off work. Treatments are usually scheduled on a Thursday or a Friday to avoid this as a problem for working patients.

Does it Hurt?

We minimise the amount of discomfort the patient experiences through the use of a Zimmer cold air machine, for which cold air is directed to the skin in the regions we are lasering. All patients for facial lasering are always given the option of a topical anaesthetic cream applied to the pre-treated area 30 – 45 minutes prior to treatment.

Pre-Treatment Instructions

  • Do not wear make-up on the day of treatment.

  • No sun-tanning or self-tanners four weeks prior to treatment.

  • Some medications or supplements should be avoided due to increasing the risk of bruising (Omega-3 fatty acid, flaxseed oil).

  • Avoid treatments that may irritate the skin for 1 – 2 weeks prior to treatment (waxing).

  • History of cold sores may require an anti-viral prescription prior to treatment.

Vascular and Pigmented Lesion Post-Treatment Instructions

  • Ice-packs should be applied to the area for the first 48 hours.

  • To reduce redness, a mild topical steroid will be prescribed.

  • The area should be washed with a liquid soap and gently patted dry. Vigorous cleaning and rubbing of the area should be avoided. If scab(s) develop, they usually last around a week. Vaseline should be applied to those sites.

  • Once the redness has settled down, make-up can be used, as well as an effective sunscreen.

  • Avoid heat and hot tubs for 1 – 2 days.

  • Avoid irritants a few days post-treatment: products containing tretinoin, retinol, benzoyl peroxide and glycolic/salicylic acids.

  • It is important to avoid sunlight and solariums in the healing phase.

  • Leg vein treatments only: Compression stockings are optional. Avoid high impact exercise for 3 – 5 days. Hemosiderin staining (brown staining) may occur after a treatment and usually resolves with time.
