PICO Laser | Fractional Laser Treatment
PICO Laser treatment is based on the principle of selective photothermolysis. This is when the target skin chromophore absorbs photons, leading to its destruction by thermal energy.
So what is laser therapy?
What are the benefits of a Medical grade laser?
- Natural glow, healthy radiance
- Lightening blemishes and spots
- Firm and tighten pores
Lasers breach the epidermal barrier and reach the correct depth of penetration through varying the following factors:31
- Wavelength: longer wavelengths have deeper penetration
- Spot size: smaller spot size increases depth of penetration
- Energy: larger (higher) energy has deeper penetration
What is PICO LASER?
PICO laser procedure uses high speed, non-thermal pulsed energy to treat tattoos, melasma, age spots and unwanted freckles.
How does PICO LASER WORK?
PICO LASER works by using ultra-short laser pulses (PICOSECOND IN DURATION = 10 ¯ 12 seconds) of 2 wavelengths, photo-mechanical shockwaves. This selectively shatters the pigment and stimulates remodelling to skin simultaneously, requiring significantly fewer treatments compared to other lasers.
What are the results with PICO LASER?
- PICO laser produces instant results.
- Fairer, more radiant skin, with obvious lightening of skin pigmentation.
- Can be used to treat the face, neck, décolletage or anywhere of concern.
How is the PICO LASER TREATMENT?
- PICO Laser treatment is pain free, produces immediate results with no downtime.
- Treatment with PICO lasts 15 minutes – a genuine lunchtime laser.
- Suitable for all skin types, most notably darker/ Asian skin tones that have a higher risk of post inflammatory hyperpigmentation.
Lasers can be classified under two broad categories, namely ablative and non-ablative.
Ablative Fractional lasers
So what is skin resurfacing?
What can ablative fractional laser treatment treat?
- Acne Scars
- Moles, Milia, Skin lumps
What can ablative fractional laser treatment achieve?
- Texture improvement with pore refinement
- Smoother skin
- Clear and brilliant skin
Ablative treatment is in the form of CO2 and Erbium-YAG lasers. It involves the use of electromagnetic energy to induce damage to the entire epidermis and a portion of the upper dermis – the chromophore here is water. Their function lies in skin resurfacing. CO2 works at a 10600 nm wavelength, which targets water both intra- and extracellularly.
Erbium-YAG works on a 2940 nm wavelength, targeting water both intra- and extracellularly, but because it is more selective for water, its energy is mainly confined to the epidermis and superficial papillary dermis, hence there is less depth of penetration compared to CO2, so side effects are reduced, but peak efficacy is less rapid than the CO2 machine.
A subset of ablative lasers is fractional ablative lasers, namely the fractional CO2 and fractional Erbium lasers. They work through inducing microthermal zones, with healthy skin cells inbetween, therefore promoting faster healing and recovery. The potential for improvement in skin resurfacing is dependent on the depth and extent of tissue damage.14,15,16,17
Non-ablative resurfacing treatments target structures in the underlying dermis, while protecting the overlying epidermis. This is achieved through varying the wavelength, energy, pulse duration and spot size. Some examples include Pico Laser, Q-switched Nd:YAG laser, intense pulsed light (IPL) and light-emitting diode (LED).
PICO Lasers, Q Switched Nd:YAG and IPL can be used to treat pigmentation, pores and acne and, to a small degree, skin texture. Q-switched Nd:YAG 1064 nm lasers, through a process of selective photothermolysis, target the chromophore and melanin in the epidermis, hence reducing damage to the overlying epidermis.12 Long pulsed 1064 nm Nd:YAG lasers, through increasing pulse duration, protect the epidermis, while targeting chromophores, water and oxyhaemoglobin in the dermis. They work to stimulate collagen and reduce vascularity in deeper vessels.12
IPL via a broad-spectrum wavelength of 515 nm to 1200 nm is based on the principle of selective photothermolysis, selectively targeting melanin and haemoglobin in the superficial skin layer.11-14
What can non ablative laser treatment treat?
- Dull Skin
- Pimples, Acne
What can non ablative laser treatment achieve?
- Brightening, whitening effect
- Clean and clear skin
- Natural radiance
