Wrinkles – what are they and why do they happen?
Wrinkles are creases, folds or ridges in the skin. Most commonly, wrinkles appear as
we get older. However, they may develop after our skin has been immersed in water
for a long time. The first wrinkles to appear on our face tend to occur as a result
of facial expressions. Sun damage, smoking, dehydration, some medications, as well
as a number of other factors may also cause wrinkles to develop.
Wrinkles are an inevitable part of the natural aging process. As we become older our
skin gets thinner, drier and less elastic. Our skin’s ability to protect itself from
damage is also reduced as we age. Eventually, wrinkles, creases and lines form on
our skin. Apart from the factors mentioned above, a person’s genetic makeup also
influences how wrinkly we become, and when and where wrinkles start appearing.
Even though wrinkles can give people an aspect of wisdom, most people do not welcome
them. Billions are spent globally on treatments to get rid of them. Some make great
claims but have no effect, while others either have moderate, significant or very
Most wrinkles tend to appear in the parts of the body which receive the most sun
exposure, including the:
Backs of hands
Tops of forearms.
The main types of wrinkles are Dynamic and Static.
Dynamic lines are fine lines and wrinkles that are visible only if the facial
muscles are contracted to form different expressions. There are 2 main types of
lines and wrinkles: dynamic and static.
The dynamic lines can form paths and permanent lines and wrinkles in time. The
forming of dynamic wrinkles can be stopped with cosmetic treatments, which will
hinder the formation of static wrinkles. Static wrinkles require more ample
Dynamic lines or wrinkles form when the face is contracted to form different
expressions while smiling or frowning. The skin gets wrinkled and paths will form.
The dynamic wrinkles are only temporary and if the skin is elastic, it will spring
right back to its normal position. The dynamic lines are more frequently formed in
the eye area (i.e. when smiling) or between the eye brows (when frowning).
Nasolabial folds also form when smiling, while some people form dimples in various
Static Lines and Wrinkles
Static wrinkles are different from dynamic lines or wrinkles, as they are visible
even if the facial muscles are not being used. When the face is at rest, the static
wrinkles will be noticeable. The most frequently seen static lines are around the
eyes (crow’s feet), nasolabial folds or wrinkles on the forehead.
However, dynamic wrinkles contribute to the formation of static wrinkles. As the
skin gets older and loses its elasticity, after smiling or frowning, the skin will
not spring back immediately. In time, static wrinkles can form, indicating where the
dynamic wrinkles typically form.
Static wrinkles form as the skin loses its elasticity and there is a lower
concentration of collagen, which keeps the skin tight and evenly surfaced.
Preventing Dynamic Wrinkles
While avoiding smiling or frowning can be a way to prevent the formation of dynamic
lines, it is difficult to control the muscles at all times. There are a few cosmetic
solutions to prevent the dynamic lines from forming, including BOTOX®
Most basic wrinkle treatments, if they have any effect, tend to help reduce the fine
lines. For deeper creases more aggressive techniques are required, such as plastic
surgery or injections (fillers). What are the main factors that cause wrinkles?
Apart from the normal aging process, the following factors are known to promote the
development of wrinkles:
Smoking – experts say that the link between regular smoking and the accelerated
aging of skin is due to a reduced blood supply to the skin.
Light skin – people with light skin tend to experience a higher level of sun
damage, which usually accelerates the development of wrinkles.
Genetic factors – if your parents developed wrinkles earlier than other people,
your chances of also doing so are significantly higher than somebody whose parents
developed wrinkles later than others.
Hair – some hairstyles provide more shade for the face than others.
Clothes – people who tend to wear hats and long sleeves usually develop wrinkles
later in life compared to other people of the same skin type.
Some jobs – people whose jobs expose them to more sunlight tend to become
wrinkly earlier than others. Examples include fishermen, farmers, sailors, golfers,
tanning booth employees (UV exposure), and gardeners.
Exposure to UV (ultraviolet light) – apart from those mentioned above who have
jobs that expose them to more sunlight, people who spend considerable time out in
the sun during their leisure hours are more likely to develop wrinkles earlier.
Facial expressions – people who repeatedly smile, frown, or squint will develop
fine lines and wrinkles earlier than other who do not do these facial expressions so
often. According to the Mayo Clinic, each time we use a facial muscle a groove forms
under the surface of the skin. When you are young the skin springs back, but as it
gets older and loses its flexibility springing back becomes harder and less
frequent, resulting in more permanent grooves.
What are the treatment options for wrinkles? Getting rid of wrinkles or taking steps
to postpone their development are nearly always optional measures, because wrinkles
are not usually considered as medical conditions or diseases – they are not
generally life-threatening or harmful to physical health. It is important for the
individual to bear this in mind when considering treatment options.
Topical retinoids – these are said to help reduce fine wrinkles, some
pigmentations and skin roughness. Topical renitoids are derived from vitamin A. As
this medication can make the skin more susceptible to burning from sunlight
exposure, the patient needs to use it with a skin-care program to protect the skin.
Topical retinoids may sometimes cause dryness, itching, a burning sensation, a
tingling sensation and redness.
OTC (over the counter, no prescription required) wrinkle creams – the
effectiveness of OTC wrinkle creams varies considerably, and depends mainly on what
its active ingredient is.
Slight to modest results may sometimes be obtained from retinol, alpha
hydroxy acids, kinetin, coenzyme Q10, copper peptides and antioxidants. The active
ingredient concentration in an OTC wrinkle cream will be significantly lower than a
prescription one. In most cases if any results are noticed, they do not usually last
Surgery and other medical procedures
Dermabrasion – a surgical procedure involving the controlled wearing away
(abrasion) of the upper layers of skin with sandpaper or some other mechanical
means. Dermabrasion is used for the removal of fine wrinkles, tattoos, nevi (moles),
and scars (such as acne ones). There will be some scabbing, swelling and redness,
which generally go away after a couple of weeks. The pinkness may take several
months to fade. Desired results are not immediate and may take several months too.
Microdermabrasion – a powerful vacuum is used to spray microcrystals of
aluminum oxide across the surface of the skin. The procedure removes the outermost
layers of skin cells – part of the stratum corneum – as well as stimulating cell
growth in the underlying dermis. Microdermabrasion is said to help give a fresher
and smoother appearance to the skin, as well as diminishing the appearance of lines
and wrinkles, enlarged pores, coarse skin, and sun damage. The patient may have
slight redness in the areas of treated skin. Repeated treatments are required
because results are temporary.
Laser, light source and radiofrequency – in wounding (ablative) laser
resurfacing, the epidermis (the outer layer of skin) is destroyed by a laser beam,
while the dermis (underlying skin) is heated up – this stimulates the development of
new collagen fibers. When the wound heals, new smoother and tighter skin is formed.
Ablative laser resurfacing can take several months to heal up. Newer therapies using
laser technology may result in faster healing times. Non-ablative lasers,
radiofrequency devices and pulsed light sources do not damage the epidermis – the
dermis is heated, triggering the formation of new collagen and elastin. The skin
feels firmer and appears refreshed after several treatments, resulting in faster
recovery times; while at the same time more treatments are required and results are
Botox – (Botulinum Toxin Type A) – Botox blocks the chemical signals that
cause muscles to contract. It is injected in small doses into targeted muscles. If
the muscles can no longer tighten the skin flattens, giving a less wrinkled and
smoother appearance. Botox is effective for lines on the forehead and between the
eyes (frown lines), as well as crow’s feet (around the corners of the eyes). As
treatments generally last about three to four months, repeated injections are
Chemical peel – a chemical solution is applied to wrinkly areas, causing
dead skin to slough off and eventually peel off, hence the name. The regenerated
skin is generally smoother and less wrinkled than the old skin. Some types of
chemical peels can be bought and administered without a medical license. However,
patients are advised have a medical health care professional perform the treatment.
Face lift – also known as a rhytidectomy, this is a type of cosmetic surgery
aimed at giving a more youthful appearance. A rhytidectomy usually involves removal
of excess facial skin and fat, with or without tightening of underlying tissues. The
skin of the patient’s face and/or neck is redraped. According to the Mayo Clinic,
USA, treatments usually last from 5 to 10 years. Healing times may be lengthy and
the patient will experience bruising and swelling for a few weeks after surgery.
Soft tissue fillers – these may include collagen, hyaluronic acid, or fat.
They are injected into deeper face wrinkles, plumping and smoothing them out, giving
the skin more volume. Patients may sometimes experience swelling, redness and
bruising in the treated areas for a short period. As with Botox treatment, for
lasting results the treatments will need to be repeated every few months.
How good the results are depend on several factors, including where the wrinkles
are, as well as their depth. There is no current treatment that can stop the ageing
process. Preventing wrinkles and lines There is nothing we can do to stop the ageing
process; eventually everybody will have wrinkles and lines, which become more
prominent over time. However, the following steps may help slow the process down:
The skin and sunlight – the more the skin is exposed to the sun the faster it
will age. Protecting your skin by wearing hats, protective clothing and sun screens
will reduce sunlight damage, and consequent developing of wrinkles. Remember that
sunlight is a vital source of vitamin D for humans. A growing number of experts
today are recommending a healthy balance of some sunlight skin exposure, while at
the same time avoiding excess.
Moisturizers – these will not prevent the wrinkling process, but may help
temporarily make tiny lines and creases less evident.
Smoking – smoking accelerates the ageing of skin. Even if you have been a long-
term heavy smoker, giving up will help slow down the current ageing rate of your
Sleep – although this has not been extensively clinically proven, many experts
say that people who get at least 7 hours good quality sleep each day will over the
long-term enjoy better physical and mental health, as well as protecting the quality
of their skin.
