After the re-invention of the cutaneous laser in the 1980’s, physicians were able to pursue laser skin rejuvenation in lieu of some chemical peels and mechanical abrasion techniques. Carbon dioxide lasers were used for skin resurfacing, but that technique was not used widely, since the thermal damage resulted in excessive scarring.
Now surgeons are able to use high energy, short-pulsed lasers and other systems that limit the amount of heat transferred to the skin. These safer lasers can remove layers of damaged skin in a very precise way, with only a bit of thermal necrosis.
For the effects to be felt in the skin, lasers must be absorbed by the targeted area. Two types of lasers are used most widely for skin resurfacing. The first uses pulsed carbon dioxide and the second uses a flash scanner in conjunction with a continuous wave carbon dioxide laser.
Similar to dermabrasion and chemical peels, the complete removal of the epidermis and a bit of the dermis results in a wound that elastin and collagen will help to heal, with tighter, firmer and healthier skin. There is some collagen shrinkage caused by heat, but it is not known whether the shrinkage will persist and lead to collagen tightening.
Your skin must be classified as a certain type before it can be determined if you are a good candidate for laser skin rejuvenation. Carbon laser resurfacing isn’t recommended for people with skin color that is not brunette, white or light white. If you have very thin or thick skin, you will not usually be accepted for this procedure. Skin firmness (lax versus firm) and skin fragility (fragile versus tough) and your skin type (dry, normal or oily) will all be taken into account before you will undergo any resurfacing.
In addition, your surgeon will assess the degree to which your skin is photoaged, by judging your wrinkling degree, and other facets of your skin. If you have allergies to the systemic or local anesthesia, you will probably not receive laser skin rejuvenation. Patients should also have a realistic outlook as to what degree of improvement will be achieved. Patients who demonstrate instability psychologically may not receive the treatments, as they will find it difficult to withstand the course of post-treatment care and the potential complications.
The surgeon will recognize whether you are a suitable candidate after answering these and other questions. Taking only suitable candidates will help maintain desired outcomes. As a rule, patients from forty to sixty-five years of age, with moderate wrinkles and fair skin are the best candidates. You should also realize that laser skin rejuvenation will not magically erase all scars or wrinkles, but rather will improve the overall appearance of your face.
Laser resurfacing with a carbon dioxide laser will enable you to have good results if your skin surface changes are from mild to moderate, and if you have wrinkles but not deep furrows. Your health care provider may also combine laser skin rejuvenation with Botox injections, for a better look after the treatments.
