Skin Rejuvenation is Simple and Complex Part II
Before we understand how lasers can produce miracle results we must look at the process of aging skin. Skin ages as a result of 2 phenomena: chronologic aging (some of you, me too? are getting older and sun damage). Chronologic aging produces a loss of all of the tissue layers in the face including bone, muscle, fat, and skin. The collapsing (shrinking) head makes the envelope (the skin) redundant and it tends to hang down. The loss of elastic tissue makes the skin less likely to hold its shape. Sun damage causes degenerative changes in the skin which lead to changes in skin color, “broken blood vessels”, and various growths on the skin.
Without a good skin care regime as alluded to in Part I, no rejuvenation system will provide more than temporary results. Given that such a system is in place lasers can help restore skin integrity, skin appearance, and skin tightness. A laser is a beam of light. It has many wavelengths and can use the visible spectrum with all the colors of the rainbow as well as the heating rays produced by the sun and which we call infrared radiation. It can be absorbed by color, water, collagen, hemoglobin to name the most common targets in the skin. Lastly, lasers can destroy tissue or they can induce wound healing and formation of new tissue and that is the basis of how we regenerated skin with lasers.
Today patients do not want downtime and lasers have had to adapt. They produce lower energy now, they produce less swelling and inflammation, and they can be used in combination to produce the best results. Today fractional lasers are the most advanced product to produce skin tightening. The can produce up to 1000 non-visible, microscopic spots of injury in a square ½” X ½”. Downtime is limited to 12-24 hours of redness. The downside is that patients need up to 6 treatments given every 2-3 weeks to produce desired results. The upside is that patients enjoy their results for years to come and they have had a minimal interruption in their daily schedule.
Next blog must talk about why light gives life and how lasers can give quality to life.
