LASERS FOR REJUVENATION
(LASERS FOR ANTIAGING / LASER TREATMENT FOR AGING SKIN)
Signs of intrinsic aging include:
Aging is a continuous and irreversible process. Prevalence of aging-related conditions is increasing due to increase in life expectancy. Skin aging is an irreversible and inevitable process, caused by a number of intrinsic mechanisms and extrinsic factors. Genetic predisposition to aging also plays an important role in determining the time and place of aging. The process of aging can be retarded to some extent, by protecting skin from harmful environmental factors, for example UV Radiation.
Wrinkles, xerosis, laxity, slackness, pigmentary changes, and benign - lesions - e.g. seborrheic keratoses and cherry angiomas. Intrinsic aging occurs as a result of cumulative endogenous damage due to continuous formation of reactive oxygen species, which cause damage to cellular membranes, enzymes, and DNA. Other factors that play a role in aging include genetic determination and changes in hormone levels. Skin aging is also affected by decrease in the levels of oestrogen, testosterone, and DHEAS etc. Other hormones such as Thyroxin, Insulin, Cortisol, Growth hormone, and Melatonin also decline with age and contribute to skin aging.
Signs of extrinsic aging include:
Solar elastosis, actinic keratosis, and dyschromias. Extrinsic aging develops due to various factors such as UV radiation [sun exposure], stress, poor nutrition, air pollution, smoking, alcohol abuse, and ionizing radiation etc. UV radiation is a major factor for extrinsic aging, also known as photo aging. The skin's response to UV radiation depends on the genetic predisposition to this kind of damage. Of late, there has been a change in the attitude towards aging and aging is no longer accepted as a natural phenomenon. There is a desire for looking young and also seeking treatments for looking young.
Several new advances in different antiaging technologies has led to the development of various antiaging therapies which aim at reduction or reversal or removal orrepair the effects of aging and photo aging. Lasers are also used to remove signs of aging.
Management of aging skin would mean avoiding risk factors which contribute to aging. Some of the methods suggested to reduce the risks of aging include:
- Avoiding stress
- Avoiding smoking and excess alcohol
- Avoiding strong sun and wind
- Eating plenty of fresh fruits and vegetables
- Regular exercise
- Adequate sleep
- Regular use of sunscreens
- Use of moisturizers to prevent dryness of skin
Aging skin management involves medical and surgical interventions. There are various medications, both topical and systemic, which help in delaying aging or repairing the aging process: e.g. topical retinoid, moisturizers, antioxidants etc.
Like laser acne scar removal treatment, there are laser as well as various surgical modalities of treatmentavailable for skin rejuvenation. These include non-invasive laser treatment for anti-aging such as:
- Low energy non-ablative lasers
- Intense pulse light treatment
- Nd - yag laser etc.
Other treatment modalities that are useful in skin rejuvenation include chemical peels, laser treatment for rejuvenation, anti-aging laser treatments, laser skin rejuvenation, and resurfacing procedure, microdermabrasion, filler treatment etc. The types of laser treatment modalities can be combined to achieve maximum benefits with minimal risk. A single patient may have multiple signs of skin aging, so treating them simultaneously with appropriate treatment modality gives a total new look to the patient.
