Laser stands for ‘light amplification by stimulated emission of radiation’.
Dermatologists use lasers for various procedures. Lasers work by emitting high-intensity light with a single wavelength(with one colour )and unidirectional which target a particular tissue in the skin(called as chromophore).
The energy in the waves is absorbed by the chromophore in the skin and then destroys it. In case of Q switch Nd YAG laser ,the laser beam is absorbed by unwanted melanin pigment inside the skin cells and melanocytes in controlled manner which breaks into microfragments and then drained from the skin by lymphatics and thereby reducing it slowly .
Q switch ND-YAG laser is one of the most commonly used lasers.
However, laser treatment is contraindicated in conditions such as:
To sum up, laser session usually takes around 10 -15 min .
Moreover, it’s important to know that the effectiveness of the treatment is related to different factors. Such as:
In fact, you will require multiple treatment sessions at an interval of 2-8 weeks, depending on your indication for treatment.
Accordingly, the number of treatment sessions also varies. However, most patients require 4-5 sessions on an average.
Consequently, some patients will receive excellent results.
On the other hand, a few patients may receive minimal benefit from laser treatment.
However, most patients will fall between these extremes.
In short, it is important to understand that a range of results is possible. In fact, it is difficult to predict the clinical outcome of the procedure until treatment starts.
You should be aware of the risk of possible complications of laser treatment:
Transient Hypopigmentation: In most patients, the treated area loses pigmentation and becomes lighter in colour. This is temporary and may last up to 4 weeks.
Hyperpigmentation: There is some risk of increased pigmentation as a healing reaction. This is a very rare reaction with QSW Nd: YAG lasers. However, if it occurs, it may last up to 3 to 6 months.
Doctors advise you to use sunscreen and medicated creams before and after the procedure. This can help prevent and reduce it.
Allergic reactions to Q-switched laser treatment are also possible, but very rare. Usually these patients already has some allergy tendency who develop such reactions. In such cases, the procedure is contraindicated.
Your doctor will note and monitor for transient textural changes. However, they usually resolve within 5-7 days. Therefore, they are rarely permanent.
Consequently, longer treatment intervals are recommended if you are prone to textural or pigmentary changes.
In most cases, laser treatment provides positive results. However, at times some tattoo particles are located deep in the skin. Hence they may not be totally removed, even with repeated treatments.
As a result, these tattoos cannot normally be treated with a laser, or many repeated treatments may be needed to remove them.
Similarly, some pigmentary lesions, such as melasma, may also return after treatment.
Lasers work by emitting high-intensity light with a single wavelength(with one colour )and unidirectional which target a particular tissue in the skin(chromophore). These penetrate the uppermost layer of the skin. These light waves are absorbed into the skin. The energy in the waves destroys the desired tissue by heating it. As a result, it encourages new cells to replace the damaged cells. It stimulates new collagen formation; thereby producing new skin that is clear and smooth. Dermatologists use lasers for various procedures. Q switch ND-YAG laser is one of the most commonly used lasers.

You should visit a dermatologist if your skin condition is not responding to any kind of OTC or home remedy treatment and it is impacting your confidence. You can seek treatment for a number of conditions including acne, scars, pigmentation, melasma, unusual growths and more.
Typically, it takes 3 to 6 months for acne marks to disappear. However, if you have a scar, it means your skin is permanently damaged that requires medical attention. If acne has left raised spots or indentations, the damage has occurred even at a deeper level in the skin. A combination of treatments such as microdermabrasion, chemical peels, laser resurfacing, microneedling and fillers can be used to improve the appearance of your skin.
Before choosing any kind of skin products it is best to consult a dermatologist, this is especially important if you suffer from sensitive skin. If you have oily skin, look for skin products that contain alpha hydroxy acids such as glycolic acid or salicylic acid. For dry skin look for moisturizing agents such as shea butter. In case you have sensitive skin, go for products that are all natural such as aloe vera.
Your skin may take time to respond to the treatment. It may need multiple sessions of treatment to show any results. Consult with your dermatologist about how long you need to wait for results and do not discontinue treatment earlier.
Signs of aging can begin in your early 20s or 30s. You can consult a dermatologist for preventive measures. More often than not, anti-aging precautions should be adopted in the early years to retain the skin’s elasticity. This includes incorporating products that have retinoids and peptides that boost the skin’s turnover rate, promoting more collagen production. It helps in restoring the skin’s barrier and maintains its youth. Other methods for anti-aging include facial exercises, a balanced diet, and also special anti-aging treatments that include facials, dermal fillers, botox, chemical peels, and even non-ablative skin rejuvenation techniques. Depending upon your age and intensity of the signs of aging, a board-certified dermatologist will be able to recommend what’s best for you.
