| Laser pulses triggered at the surface layer of the skin, vaporizing water and the skin’s surface without touching deeper layers. A new surface layer will then grow back – a layer that is soft, wrinkle-free, and younger looking. The heat produced during the process also shortens the collagen fibers in the skin, which re-establishes some of its elasticity. Different Types of Lasers are Accessible
They differ according to their wavelength and pulse duration. These differences depend on the depth at which they target the skin, the level of heat generated, and the likelihood of affecting surrounding tissues. 1) Carbon Dioxide (CO2) lasers – the most powerful laser, used for deep wrinkles. Note: CO2 lasers may be unsafe for people who have had silicone injections, as the laser can burn and scar the skin over implanted areas. 2) Erbium: YAG (Er: YAG) laser – is gentlier than the CO2 laser and helpful for mild wrinkles. It targets tissue more exactly than the CO2 laser and causes less damage to surrounding tissue. Recovery after Er: YAG laser treatment is shorter than that after CO2 laser treatment. Whilst used at sufficient depth, some surgeons can eliminate deep wrinkles with the CO2as effectively as this laser is more powerful, but with fewer side effects. The multy-functional Pulse YAG laser is an alternative between pulses that destroy tissue with pulses that heat the skin, and this process also resurfaces the skin as effectively as CO2 but with fewer side effects. 3) A combination of CO2 and Er: YAG laser treatments are now getting popularity. In this treatment, the Er: YAG laser is first used to remove the epidermis, followed by use of the CO2 laser to achieve tightening of underlying collagen. This produces the collagen-tightening benefits of CO2 therapy but with minimal harm to surrounding tissues. 4) NLite – Non-ablative laser resurfacing, also called Photorejuvenation, uses light energy to encourage the new growth of collagen without removing skin tissue. Even as it is less powerful at removing wrinkles than other resurfacing methods, it may be used for delicate areas such as the eyes and neck, and causes little irritation
In addition to laser procedures, many resurfacing methods are available, including botox injections, chemical peels, injectible fillers, and surgical procedures (e.g. facelift, browlift, blepharoplasty). Individuals looking to rejuvenate their skin should consider factors such as the ease, effectiveness, and safety of the procedure; post-procedural effects; potential for complications; length of recovery; and duration of benefits.
