Skin Care Laser:
Today you have a variety of options when it comes to rejuvenating your appearance. One of the newest is laser resurfacing, which can reduce facial wrinkles, scars and blemishes. Newer laser technologies give your physician a new level of control in laser surfacing, permitting extreme precision, especially in delicate areas.
It's all about using beams of light. Laser skin resurfacing is also known as a laser peel, laser vaporization or lasabrasion. Your physician uses the laser to send short, concentrated pulsating beams of light at irregular skin. This removes unwanted, damaged skin in a very precise manner one layer at a time. This targeted approach means there are fewer problems with hypo pigmentation, or a lightening of skin for procedures such as laser acne scar removal.
The laser beam used in laser resurfacing will remove your outer layer of skin, called the epidermis. It simultaneously heats the underlying skin, called the dermis. This action works to stimulate growth of new collagen fibers. As the treated area heals, the new skin that forms is smoother and firmer.
Laser resurfacing can improve minor facial flaws, such as:
- Fine lines or wrinkles around or under your eyes, forehead or mouth
- Scars from acne or chickenpox
- Non-responsive skin after a facelift
- Aged or sun-damaged skin
- Liver spots
- Improve your complexion if you have yellowish or grayish skin tones
- Birthmarks such as linear epidermal nevi
- Enlarged oil glands on the nose
Laser Hair removal:
If you're not happy with shaving, tweezing, or waxing to remove unwanted hair, laser hair removal may be an option worth considering.
Laser hair removal is one of the most commonly done cosmetic procedures in the U.S. It beams highly concentrated light into hair follicles. Pigment in the follicles absorb the light. That destroys the hair.
Benefits of Laser Hair Removal
Lasers are useful for removing unwanted hair from the face, leg, arm, underarm, bikini line, and other areas.
Benefits of laser hair removal include:
Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.
Speed. Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour.
Predictability. Ninety percent of patients have permanent hair loss after an average of three to five sessions.
Multiple treatments depending on the type of hair and skin color have been shown to provide long-term reduction of hair. Most patients need a minimum of seven treatments. Current parameters differ from device to device but manufacturers and clinicians generally recommend waiting from three to eight weeks between sessions, depending on the area being treated. The number of sessions depends on various parameters, including the area of the body being treated, skin color, coarseness of hair, reason for hirsutism, and sex. Coarse dark hair on light skin is easiest to treat. Certain areas (notably men's faces) may require considerably more treatments to achieve desired results.
Laser does not work well on light-colored hair, red hair, grey hair, white hair, as well as fine hair of any color, such as vellus. For darker skin patients with black hair, the long-pulsed Nd:YAG laserwith a cooling tip can be safe and effective when used by an experienced practitioner.
Typically the shedding of the treated hairs takes about two to three weeks. These hairs should be allowed to fall out on their own and should not be manipulated by the patient.
Laser tattoo removal:
Today, "laser tattoo removal" usually refers to the non-invasive removal of tattoo pigments using Q-switched lasers.
Tattoo removal is most commonly performed using lasers that break down the ink in the tattoo. The broken-down ink is then absorbed by the body, mimicking the natural fading that time or sun exposure would create. All tattoo pigments have specific light absorption spectra. A tattoo laser must be capable of emitting adequate energy within the given absorption spectrum of the pigment to provide an effective treatment. Certain tattoo pigments, such as yellows, greens and fluorescent inks are more challenging to treat than darker blacks and blues, because they have absorption spectra that fall outside or on the edge of the emission spectra available in the tattoo removal laser.
