Skin ageing is an unstoppable progressive biological event affecting all living creatures. It is strongly dependent on an individual’s genetic background, as characteristics differ from population to population.
Personal lifestyle, cultural habits, economic status, and environmental exposure can enfluence the effects of ageing.
Premature skin ageing results when natural ageing is combined with environmental factors. The effects of ageing differs between genders since post-menopausal women lose up to 21% of skin collagen.
Skin rejuvenation aims to decrease the many negative effects produced by factors linked to natural and environmental ageing, as well as stimulate positive cellular responses induced by controlled stressor exposures.
Thermal stress on the skin seems to be an effective anti-ageing and rejuvenation treatment. Fibroblasts is the skin have been shown to react to pulsed, non-lethal thermal exposures.
Radiofrequency,light sources and ultrasound, can all generate controlled heating within living tissues when properly administered.
Laser and Light sources as Anti-Ageing Devices Lasers and medical light sources can generate highly specific light emissions. Temperature increases are related to laser and medical light parameters as well as tissue characteristics.
Different tissue responses can be generated by controlled temperature increases to the original sites of light absorption.
Fractional laser treatment is a non-invasive treatment that uses a device to deliver a laser beam divided into thousands of microscopic treatment zones that target a fraction of the skin at a time. This is analogous to a photographic image being enhanced or altered pixel by pixel.
Fractional laser treatment has bridged the gap between the ablative and non-ablative laser techniques used to treat sun-damaged and aging skin.
Whilst ablative laser treatments work mainly on the epidermis and non-ablative treatments work solely on dermal collagen only, fractional laser treatment works at both the epidermal and dermal layers of the skin.
Fractional laser treatment works by targeting both the epidermis and dermis. It does this by delivering a laser beam that is divided into thousands of tiny but deep columns of treatment into the skin.
This fractional treatment results in a faster healing process than if all tissue in the treatment area was exposed to the laser. Ultra-short pulsed lasers Ultra-short pulsed lasers e.g. quality-switched and Picosecond systems, can generate highly specific photo-thermal responses within living tissues due to the unique way they deliver high peaks of light energy during extremely short time periods within the range of nanoseconds and picoseconds.
Laser systems can also deliver their light energy in full-beam mode or fractional-mode to produce highly controlled cellular stimulation. Intense pulsed light Intense pulsed light is commonly abbreviated as IPL.
Various cutoff filters are commonly used to filter out lower wavelengths, especially potentially damaging ultra violet light. The resulting light has a spectral range that targets specific structures and chromophores that are heated to destruction and reabsorbed by the body. IPL shares some similarities with laser treatments, in that they both use light to heat and destroy their targets.
But unlike lasers that use a single wavelength of light which typically matches only one chromophore, and hence only one condition, IPL uses a broad spectrum that when used with filters, allows it to be used against several conditions. This can be achieved when the IPL technician selects the appropriate filter that matches a specific chromophore.
Ageing prevention with laser and light sources
Age prevention is a popular concept that is becoming more accepted by people in the early stages of their ageing process. Further prevention is encouraged in patients that have already undergone some sort of anti-ageing skin treatment aimed at rejuvenating their skin.
Primary age prevention focuses on slowing down the signs of ageing, mostly on sun-exposed areas such as the face, neck and hands.
Secondary age prevention tries to keep clinical improvements achieved after personalized treatments aimed at correcting already evident ageing signs, for as long as possible.
Primary and secondary age prevention should have a common strategic approach, which is aimed at achieving an ‘elegant’ ageing process. Just the right amount of technology provided by experienced physicians dealing with complex skin ageing is what people desire.
Dr Ayham Al-Ayoubi: The skin ages spontaneously through natural ageing. Natural skin ageing is deeply affected by environmental factors, where sun exposure, tobacco smoking and nutrition play important roles.
Age prevention and rejunevation techniques are constantly evolving. Proper prevention can be obtained through periodic, personalised, minimally invasive treatments associated with short downtime and minimal side-effects, to allow the stimulation and production of collagen.
The beneficial effects of laser and medical light sources to temporarily reverse, slow down and prevent clinical signs of ageing has individuals seeking specialized anti-ageing advice to take maximum advantage of these continuously evolving technologies.
At the London Medical & Aesthetic Clinic, Dr Ayham Al-Ayoubi uses the most advanced lasers and light technologies to create the most effective anti-aging and age prevention treatments. Dr Ayham Al-Ayoubi may use a combination of treatment options in order to maximise the aesthetic result.
