The skin is composed of the epidermis and the dermis. Within the dermis are two layers, both of which are constructed of collagen, long fibers that loosen and stretch with age and sun damage. If the deepest layer, the reticular layer, is damaged, scars result, while the upper layer of the dermis, the papillary layer, heals from injuries without scarring.
Laser skin rejuvenation is used to resurface facial skin with wrinkles caused by excess sun exposure, “crow’s feet,” and acne scarring. The high energy, amplified light wave of laser vaporize the top layer of skin instantly, with no beeding and minimal trauma to the surrounding skin.
Laser resurfacing can be done with:
Ablative laser. This is a wounding laser, which removes thin layers of skin. Types of ablative treatments include the carbon dioxide (CO2) laser and the erbium laser.
Nonablative laser. This is a nonwounding laser, which stimulates collagen growth and tightens underlying skin. This includes many types of lasers as well as intense pulsed light (IPL) devices.
Immediately following Laser skin rejuvenation we apply a dressing to your skin. Swelling and “crusting” of the skin are normal, and ointments to keep the skin supple will be applied for seven to 10 days following surgery. The redness of skin that persists after the initial healing phase will usually fade in about one month.
In one to two weeks after surgery, new skin will emerge that is pinker, finer, and free of many wrinkles. But it will take several weeks for all the redness to vanish. Follow-up care involves using sunblock in order to protect the skin while new pigment is created. Patients will notice that the skin remains lighter for a long time after surgery, but that condition will usually subside when the skin’s pigment level has been restored.
Ablative laser resurfacing can cause various side effects, including:
Scarring :Ablative laser resurfacing poses a slight risk of scarring.
Redness, swelling and itchin: After ablative laser resurfacing, treated skin will be itchy, swollen and red. Redness can be intense and might last for 6 months. The aggravation of a previously existing skin condition, such as rosacea, can contribute to redness.
Changes in skin color : Ablative laser resurfacing can cause treated skin to become darker than normal or lighter than normal). Hyperpigmentation is more common in people who have darker skin. Topical retinoic acid or glycolic acid can help treat hyperpigmentation after the treated area has healed. Use of sunscreen during the healing process also is important.
Infection: Ablative laser resurfacing can lead to a bacterial, viral or fungal infection. The most common infection is a flare-up of the herpes virus.
Nonablative laser resurfacing also can cause side effects, including:
Changes in skin color: If you have tanned or darker skin, nonablative laser resurfacing can cause your skin to become temporarily darker.
Mild swelling and redness. last only hours or days.
Infection : Nonablative laser resurfacing can cause a flare-up of the herpes virus.
In general, we apply the necessary anesthetic and then passes the hand-held wand or paddle that transmits the laser light beam over the skin to be treated. Once the procedure is over, we apply antibiotic cream to the treated skin. The whole procedure takes between 30 and 60 minutes.
This will depend on your unique needs, goals, and skin condition, although non-ablative lasers generally do require more than one treatment session for maximum results . This is something that you should discuss with the doctor during your consultation to give you a better idea of your comprehensive treatment plan.
You may notice some redness or peeling following your laser skin rejuvenation session, but these symptoms should diminish on their own within a few days. Following each treatment session, you should begin to see your final results taking shape .
Not usually. Scarring is not typical with laser resurfacing if the procedure is performed by an experienced surgeon. However, people with a tendency to form keloids or excessive scarring may not be good candidates for laser resurfacing.
Laser resurfacing can be done at almost any age on people with skin damage from aging, sun exposure and acne scars, or those wishing to get rid of birthmarks, lesions and tattoos .
