Ageing is a continuous dynamic chronological process. A person starts ageing from the time that he pops out of the womb. The baby’s age is recorded in days, then months, then years and in no time by the number of decades. Later in life, age is celebrated by various precious medal jubilees. Ageing is an inevitable part of life. According to the law of nature, everybody will age, but some quicker than others. The movie “The curious case of Benjamin Button” is partially correct, as conditions exist where one can age very quickly, however the reverse part is not possible. The condition that can make a ten year old child look like a sixty year old with very rapid ageing is called Progeria.
A person will age naturally as determined by his genes. Every time the cells in our skin replicates, certain DNA chromosomes become slightly shorter and this leads to us becoming older. However, there are many external factors that add to this process, making our skin look like that of a geriatric at a faster pace. These extrinsic factors include, UV radiation, temperature variation (global warming), wind, humidity, chemical pollutants and irritants, poor nutrition,physical and mental stress, excessive use of untested abrasive compounds on the face and poor social habits like smoking. Factors such as smoking are important both from the view of premature ageing, as well as its therapy.
The older skin is characterised by the following: dryness, loss of elasticity, deeper expression lines, wrinkles, irregular pigmentation as well as decreased healing from bruises. Associated with old age, there is a list of other unwelcomed skin disorders that are listed in the table.

For most people, wrinkles are the earliest and cosmetically most undesirable problem, which at times can be used as an indicator that one should start planning their pension policy in readiness for retirement. These wrinkles can appear in stages, getting deeper with time. Glyphic wrinkles are only accentuated normal skin creases, which are normal in young individuals with increased sun exposure. Thereafter linear furrows start appearing as long grooves, which are straight or curvy on the forehead. One can also encounter wrinkles that radiate as crow’s feet from the lateral side of the eyes. They can also extend as creases from the nose to the corner of the mouth. Finally, crinkles are very fine criss-cross wrinkles that occur even in the sun-protected areas of most elderly persons. Wrinkles are also classified as being static, when they follow facial expressions. They are regarded as dynamic, when they follow ageing and physical tension.
When a patient presents to a dermatologist, he can be classified on the basis of examination of wrinkles. The table below gives a brief summary:
Type I |
Age between 18-30 Early sun damage Very little pigment changes No keratoses No wrinkles |
Type II |
Patient in forth decade Moderate sun damage can be noted Keratoses can be felt as rough spots Crow’s feet and parallel smile lines visible Wrinkles in motion |
Type III |
Age 50 or older Significant amount of sun damage Obvious changes of thickness of the skin, with visible capillaries and mottled pigmentation Sebaceous hyperplasia Wrinkles at rest |
Type IV |
Above 60 yrs olds Severe sun damage Yellow-grey skin Prior skin malignancies Deep wrinkles |
Although several treatments are available for skin rejuvenation, prevention where possible is still the most important factor. The rejuvenation programme consists of the use of the following modalities alone or in combination. The choice of therapies to be instituted depends on the age of the patient, skin conditions, skill of the skin specialist, financial consideration and most importantly the expectation and desire of the patient.
- Prevention by protecting oneself from the sun. The use of sunscreens, hats, umbrellas and long sleeved shirts, tend to help. The choice of sunscreen is very important and should contain both SPF for UVB and UVA. Unlike what beauticians have been advising patients, a high SPF is better. Beauticians trying to sell sunscreens with low SPF at exorbitant prices have been spreading wrongful myths that high SPFs are detrimental to your skin. Good habits that help the skin are: Adequate sleep and fluid intake and no smoking. A reduction in alcohol consumption will also help.
- Proper nutrition with balanced diet, including all vitamins and antioxidants. Exercise increases blood flow and nutrition to the skin.
- Daily skin care: The use of gentle soaps and proper moisturising of the dull lustreless skin will help in giving the skin a healthy look.
- Cosmeceuticals: Alpha hydroxyl acids, retinoids and vitamin C. Retinoids prevent collagen breakdown and improve sun damaged epidermal atrophy, dysplasia, keratosis and dyspigmentation. Thus it helps reverse sun damage. Vitamin C helps in pigmentary problems, as well as helps in the synthesis of collagen.
- Non surgical therapy: Massage, facial masks, sonar, Iontophoresis, micro-current stimulation.
- Surgical therapy: Various chemical peels, dermabrasion, lasers, Botulinum toxin, fillers and surgical face lifts. There are many other surgical procedures, all with their pros and cons and the outcome of these procedures depend greatly on patient selection and the expertise of the specialist.
All these modalities can be combined and used to improve the appearance of the person.
In conclusion: One cannot prevent the aging process, however, one should try to age gracefully. Habits can play a big role and a Dermatologist or a Plastic surgeon can make a huge difference. Many simple procedures are available and should be chosen carefully. Whilst there are many treatment modalities offered by beauticians, procedure like colonic lavage, do not erase years from the skin.
