About Fractional Resurfacing Laser Treatments

At Dermature we use Sharplight Omnimax S4 for Fractional Laser for clients concerned about wrinkles, fine lines, acne scars, and irregular skin texture.

Fractional laser treatments effectively tighten and reduce the signs of aging and damage caused by the environment and improve the skin's texture, resulting in smoother, younger looking skin where it counts - on the face, neck and hands. Our revolutionary Er:YAG laser produces a micro epidermal peel, which through a thermo-mechanical reaction, removes the problematic areas on the top layer of the skin. The fresh layer that grows has an improved texture, reduced or disappeared rhytids, wrinkles, scarring and spots and an overall renewed radiance.

Pre-Treatment information

Discontinue Accutane 6 months prior to treatment.

Discontinue use of Retinoic Acid products 2 weeks to treatment.

Avoid sun exposure or the use of tanning beds and self-tanners for at least 4-8 weeks, prior and/or between Laser treatments (dependant on skin type).

Do not exfoliate, use glycolic acid, benzyl peroxide or any other skin irritants one week, prior to treatment.

Avoid Microdermabrasion’s or peels for two weeks prior to treatment (notify treating practitioner if these kinds of treatments have been performed within 3 weeks prior to treatment). If the skin is red, irritated or sunburned, the Laser treatment must be rescheduled.

Avoid strenuous exercise for 24 hours prior to the clinical treatment.

Avoid alcohol 48 hours prior to treatment.

Post-Treatment Care

Until the skin has healed, wash face with a soap free cleanser.

If there are scabs or blisters, make-up should not be used for 4-5 days.

For at least three weeks post Laser, do not use harsh topical exfoliations, glycolic acid, benzyl
peroxide, acne creams etc.

Avoid touching, rubbing, peeling or picking of the skin, as this may cause hyper/hypo-pigmentation, infection or scaring.

Gently apply soothing creams/moisturizers on the following days.

For 1 week, avoid hot baths, showers, hot tubs and saunas. When showering and washing, gently pat dry and do not rub.

Avoid strenuous exercise for 48 hours following clinical treatment.

Avoid alcohol 48 hours post treatment.

Are the treatments safe and painless?

SharpLight's pulsed-light treatments are non-invasive and 100% safe.

A topical anaesthetic will be applied. Most patients find the treatment quite tolerable, experiencing more of a heat/prickly sensation rather than pain. To overcome this, we use a cool cold compres after the treatment.

Once treated, ointment will be applied and provided for home care.

How much downtime will I have?

With the fractional laser treatment there is downtime of 5-7 days after a treatment on the face. For off face areas, such as hands/arms, where healing is slower the process may take up to 2 weeks.

What is the diffrence between Fractional Laser and Carbon Laser Peel?

Fractional laser treatments use laser light to create microscopic wounds in the skin, which stimulates the body’s natural healing process and helps reduce wrinkles and other signs of aging.

Carbon laser peels use Nd:YAG Q Switched Laser and a carbon-based solution to remove the outermost layer of skin cells, resulting in a smoother, brighter complexion. Both treatments can be used to improve the appearance of wrinkles, acne scars, and pigmentation.

However, fractional laser treatments are typically more effective at treating deeper wrinkles and can also improve skin tone and texture. Carbon laser peels are generally better suited for treating superficial skin imperfections.

What is the difference between CO2 Ablative Laser and Fractional Non-Ablative Erbium Laser?

CO2 ablative lasers are used to remove the outer layers of skin, such as wrinkles and age spots. They also help to tighten underlying skin and stimulate collagen production, resulting in smoother skin. The laser energy is delivered in short pulses of high intensity, which vaporizes the top layer of the epidermis. This procedure requires several days of downtime for healing and can cause redness, swelling and discomfort.

Fractional non-ablative erbium lasers are used to treat mild cases of wrinkles, hyperpigmentation, acne scars and other signs of aging. Unlike CO2 ablative lasers, this type of laser does not remove any part of the outer layer of the skin; instead it creates tiny columns in the skin that penetrate deeper into the dermis without damaging surrounding tissue. This leads to a much quicker recovery time with minimal side effects such as redness or swelling. It also stimulates collagen production over a longer period of time than CO2 ablative lasers, resulting in long-term improvements in skin texture and appearance.

In the past, many physicians believed CO2 laser were the best way to treat acne scars, wrinkles, and other skin blemishes. However, more dermatologist, physicians and patients are choosing Fractional laser Erbium : Yag technology over CO2 laser thanks to its impressive results and safe, gentle treatments.
