Skin Rejuvenation Made Easier
Aging is a beautiful, terrifying thing. While the added wisdom and experiences are good for the mind, its signs are not very welcome otherwise – for instance as wrinkles and spots on the skin. Till the age of thirty, cell regeneration rate is faster than the rate of damage, thereby eliminating the need for excessive invasive treatments – unless any alteration in existing features are needed. But after a point of time, the rate of damage increases, making its signs very visible, especially on the skin that needs additional treatments for rejuvenation to keep it young.
Facial rejuvenation is a broad term used to classify a set of treatments, cosmetic in nature, that are aimed at restoring the youthful appearance to the human facial skin. There are both types of options – surgical and non surgical. The surgical part focuses on facial alteration to restore facial symmetry, and the surgery has to be performed by a qualified surgeon only. Other non invasive treatments focus on the areas like wrinkles, scars, hyperpigmentation etc.
Photo rejuvenation is a common solution to most skin problems. It is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds on the skin using lasers, prompting it to heal itself by creating new cells. This process reverses the signs of photoaging to a certain extent by removing appearances of damage.
Laser Resurfacing is a laser surgery technique that works by dissociating the molecular bonds. Usually used to treat wrinkles, sun damage, scarring (acne and surgical scars), stretch marks etc, it can be done using ablative laser (vaporizing tissues and creating wounds) or non ablative lasers (keeping the skin intact). Compared to other forms of treatment, laser surgery gives an option for the surgeon to customize the surgery based on each patient and focus on the exact area, however small, that requires attention.
Types Of Laser Rejuvenation Treatments
An Erbium laser (Er.YAG laser) is usually used for laser resurfacing skin treatment. Alternatively, a carbon dioxide laser is also equally popular and it was used for the first complete resurfacing treatment. Er YAG laser and carbon dioxide laser are used when the damage is due to exposure to the sun (sun damage) or age spots. The dermis is heated and fibroblasts are simulated to form new collagen and elastin, making the skin thicker.
The carbon dioxide laser resurfacing was related with hyperpigmentation and scarring due to the heat production and high degree of coagulation. While the Er YAG laser does not have these effects too, the Nd Yag lasers were developed for more efficient treatment and surgery for skin related diseases.
Nd YAG lasers, based on Neodymium, are also used extensively in the field of cosmetic medicine for laser hair removal and the treatment of minor vascular defects such as spider veins on the face and legs. Double frequency Nd YAG lasers are created using higher output bands and the frequency changes from 1064 to 532 for normal Nd YAG lasers and double frequency Nd YAG lasers. For superficial skin lesions, the easier Double frequency Nd YAG lasers are preferred.
Holmium lasers are used surgically based on the advantages of its wavelength. At a wavelength of 2.1 Microns, holmium laser has a very shallow penetration depth, greatly reducing the coagulation zone and collateral damage to the sensitive skin. Holmium lasers are used in ablative laser treatment.
Intense pulsed light (IPL) uses flashlamps and produces high intensity light over broad visible and infrared wavelengths. It uses filters to choose the desired range. Intense pulsed light (IPL) is usually used to treat acne, photodamange, vascular lesions, melasma etc. A lot of debates about its effectiveness in skin rejuvenation treatments, especially resurfacing are going on. It is a non ablative method with almost no side effects. Intense pulsed light(IPL) has become a popular treatment for pigmentation. It is safe and quick.
A pulsed dye laser uses an organic dye mixed in a solvent as a medium. Selective thermolysis is applied when a pulsed dye laser is used for skin treatment. Due to the target structure’s thermal relaxation time, the pulsed dye laser is preferred because the target cools to 50% of its peak temperature, limiting the impact from surrounding tissues.
Pigment lasers are used to treat pigmented lesions that include birthmarks, freckles and other pigmentation defects. Pigmented lasers surgery is an ablative laser surgery to be performed with trained laser surgeon with a lot of experience for dark skinned people due to the high risk of permanent hypopigmentation.
Dr. Debraj Shome is a trained surgeon who has many laser surgeries to his credit. He is a world renowned surgeon who specialises in both ablative laser and non ablative laser treatments. His treatment methods are intensely focused and are effective for all the skin types. When looking for Skin rejuvenation, you know whom to
