The erbium laser is a emits a wavelength of 2940 nanometres (nm). This laser wavelength is primarily attracted to the water in skin. This attraction to water causes controlled ablation of a very fine layer of skin. This laser can therefore be used to resurface the skin and help to reduce wrinkles, acne scarring, and pigmentation. The laser can also be used to remove various skin lesions (skin lumps and bumps).
Water is a primary constituent of the skin and the erbium laser has an extremely high affinity to the water in the skin. Therefore, as soon as the laser energy reaches the skin, it immediately vapourises the skin on contact due to its high affinity to the water in the skin. The erbium laser has a very shallow penetration depth, as once it hits the skin's surface the energy is immediately absorbed by the skin water. There is therefore very little heat energy transmitted to the deeper layers of skin.
In comparison, the carbon dioxide laser is also attracted to the water in the skin, but not as strongly as the erbium laser. Therefore, some of its energy continues to penetrate deeper into the skin's surface, as not all of the energy is absorbed immediately in the top layers. This deeper heating of the skin leads to tissue tightening and contraction, something that is not seen with the erbium laser. When resurfacing skin, often a combination of the two lasers are used to exploit both their properties.
As the erbium laser is used to remove very fine layers of the skin, it is used primarily to resurface skin for;
A consultation with one of our doctors is the first step to assess if you are a suitable candidate for erbium laser treatment. Depending on the skin type, you may require preparation with certain skin care products such as topical retinoids or hydroquinone for a month or two to help flush out excessive skin melanin and even out skin thickness to reduce the incidence of possible complications such as post-inflammatory hyperpigmentation or an uneven response to the laser.
For resurfacing of the full face, usually some form of sedation is required to make the procedure a comfortable one. We usually use intravenous sedation to achieve a level of sedation where you are still able to respond to verbal stimuli, but usually have very little memory of the procedure. After sedation is administered, local anaesthetic is injected into the face to numb the skin completely. Note that for treatment of smaller areas, it is possible not to use sedation, but when treating the full face, sedation is required due to the number of local anaesthetic injections required.
The erbium laser is suited for resurfacing skin on people who have mild to moderate wrinkles, sun damage, or acne scarring. It is best suited to fairer skin types. Those who have darker skin types are more likely to have complications from treatment (see below). It is not suited to those who are pregnant or breast-feeding, have a history of keloid scarring, and those who have had Roaccutane in the past 6 months.
The erbium laser, when used for skin resurfacing, usually takes approximately 1 to 2 weeks to recover from. The skin usually appears red, swollen, and then crusts over this period. There may be some residual redness that can persist for 1 to 2 months in some cases, depending on the severity of the treatment.
Infection with the herpes (the cold sore virus) or bacterial infection are possible after erbium laser resurfacing, and prophylatic medication for these conditions needs to be taken before and after treatment.
There is a small risk of skin pigment changes after erbium laser treatments. Especially if the patient's skin type is olive or darker, the risk of hyperpigmentation (increased skin pigmentation) or hypopigmentation (decreased skin pigmentation) is possible. Hence, we usually restrict erbium laser treatments to those with lighter skin types.
Rarely, scarring can occur with erbium laser treatments. This occurs when the depth of the resurfacing/treatment exceeds a level where the skin is able to regenerate completely.
Having a wide range of lasers to choose from helps us to provide you with the laser treatment that is most suited to your skin and skin concerns. The erbium laser is one of the tools we use, and after a consultation with one of our doctors, we will be able to decide which laser is the best one to use on your skin.
The first step is simply contacting us for your initial laser skin rejuvenation consultation, where we will discuss with you what is a realistic and achievable outcome, and what to expect from your laser treatment.
Making that first phone call about any cosmetic procedure can be a confronting task - many of our patients have preferred filling out our online enquiry form. We can then contact you with an understanding of the results you are hopeful of achieving and ensure the treatment is appropriate.
