This is a procedure of using laser light to
remove surface imperfections, and dramatically reduce lines and
wrinkles. It can gently remove sun damaged, ageing skin, layer
by layer helping to protect and stimulate the rejuvenation of
the deeper healthy skin. The CO2 laser energies are absorbed by
water and the skin contains approximately 70% water, the laser
beam actually vaporizes the top layer of the skin, or epidermis
and causes contraction of the papillary dermis, or the second
layer of the skin. The combined effect creates a smoother, tighter
surface, on the top of which a rejuvenated surface grows. The
laser light penetrates to a very precise controlled depth, making
the procedure safer and predictable and reducing the risk of scarring
or pigmentation problems. Laser surfacing is bloodless and is
performed either under general anaesthesia or local anaesthesia
with sedation depending on the individual requirements. Because
laser is gentle, the discomfort both during and after the procedure
is improved, and helps give you a more rapid return to your normal
routine. Prior to the laser treatment, you will be on a programme
of Retin A for two weeks. Patients who are prone to hyper pigmentation
(dark spots), can be treated with a bleaching cream. If you have
a history of herpes simplex, a treatment of Zovirax will be prescribed
before and after your treatment. Sun tanning should be avoided
before and for three months after the laser treatment. It is better
to mention any history of taking Acutane for acne for the last
12 months, as this has a detrimental effect on the healing of
the skin after laser treatment.
Many facial conditions such as fine wrinkling around the eyes,
forehead, nose and mouth can be smoothed out with laser resurfacing.
Deep wrinkles and frown lines can be minimized, along with acne
scars and irregular surgical scars, can be successfully treated
with CO2 laser.
In the first few days following laser treatment, your skin will
produce some oozing as the new collagen is formed by the dermal
layer to rebuild the skin from the bottom up. You will then go
through a period of crusting for 3-4 days, after the resurfacing
procedure a scab may form at the treatment site which usually
disappears within 7-10 days and may easily be covered with make
up. Complete healing usually takes place in 3-4 weeks. In some
cases, redness may persist, but usually you will be red for around
2-6 weeks which is easily camouflaged with make up, which can
usually be applied in 4-7 days depending on your skin response
to the treatment.
Post procedure discomfort is minimal, and after your skin resurfacing
it is important to use a sunscreen with SPF 25 protection against
both UV-A and UV-B rays. It is important to realize whilst laser
resurfacing is a wonderful opportunity to look youthful, it will
not completely stop the clock. The results do get better in time
with rejuvenation of collagen but new lines will appear as you
age. Some people require more that one treatment to reach their
expectations. Repeat treatment can be done within three months
of your first treatment. Others can get their expected result
with one treatment.
Complications
For the most part, lasers are very safe, however,
as with any medical procedure there are risks and benefits. A
patient may have an allergic reaction to topical ointments used
post-operatively.
Post operative outbreak of herpes virus infection can lead to
scarring and therefore it is paramount to continue taking anti-viral
medication. The wound should be kept dressed and moist because
a dry undressed wound is more likely to result in scarring. Most
patients will be pink for 2-3 months and some for as long as 6
months. Many patients will experience excessive tightness between
3-8 weeks following the treatment, others including melia, itching,
transient hyperpigmentation for 6 weeks, or hypertrophic scarring
are possible but rare and these and any other possible complications
will be discussed carefully during your consultation.
Clearly there are many options for skin rejuvenation
and the different methods available have to be chosen according
to the individual needs. These will be assessed to define an individualized
treatment plan during consultation.
