Fractional Laser]
I. What is fractional laser?
Fractional laser is also known as “beam laser” and “beam laser”, which is an image term. When these tiny laser beams are applied to the skin surface, the densely distributed dots look like imaging “pixels”, hence the name “pixel laser”.
Second, what is the principle of fractional laser?
The principle of fractional laser treatment is the “micro-trauma repair” theory. When the skin is damaged by trauma and stimulated by strong light energy, the skin can start its own healing and repair mechanism. Each tiny beam of light from the fractional laser is micro-traumatic to the tissue, and this micro-trauma is sufficient to initiate the regenerative repair function of the tissue, eventually leading to the remodeling and reconstruction of the entire skin layer, including the epidermis and dermis. Since the trauma is extremely small and the beam is surrounded by completely normal tissue structure, recovery is easy and no hyperpigmentation or scarring is formed, resulting in excellent treatment results.
Third, what problems can fractional laser solve?
The following problems can be solved.
1, skin wrinkles, sagging and enlarged pores.
2.Depressed scar caused by various reasons (acne scar, etc.)
3.Treatment of chloasma and atrophy lines.
4, skin photoaging.
IV. What are the advantages of fractional laser?
1.The treatment is easy to accept. There is only slight pain during the treatment, and topical anesthetic cream can relieve or even eliminate the pain during the treatment.
2. No or very short rest time is needed after treatment. The microscopic skin holes are difficult to see with the naked eye and therefore do not affect the aesthetics. Oozing, bleeding and infection rarely occur.
3, can be used for the full treatment of yellow people and no or very little pigmentation occurs.
V. What kind of reaction will occur after fractional laser treatment?
Generally speaking, fractional laser treatment may cause temporary and mild reactions.
1, pain: generally relieved in 10-60 minutes, the degree of pain caused by different equipment treatment may vary.
2. Erythema: The skin may be mildly red within 1 hour after treatment, and generally reduces significantly after 5-7 days.
3.Redness: When high energy treatment is chosen, it will cause mild edema of the skin, which will subside on its own in 1~3 days.
4, peeling: With further skin repair, the skin will show a slight peeling phenomenon, lasting about 2 weeks.
5.Inflammation of the skin: such as acne-like rash, pustular rash, etc.
6, Temporary hyperpigmentation: A single excessive dose on dark skin can easily lead to post-inflammatory hyperpigmentation, mainly related to fractional density, which often takes several months to resolve. Therefore, fractional laser treatment should be at least 2 weeks after sun protection, the application of fading cream can prevent or reduce the occurrence of hyperpigmentation.
Sixth, how should I deal with adverse reactions when fractional laser occurs?
The following treatment should be done in case of adverse reactions of fractional laser.
1, erythema: should avoid all kinds of stimulation, can be used topically levovitamin C to speed up the fading of erythema, can also be treated with pulsed dye laser or strong pulse light.
2.Pigmentation.
Light avoidance: sunscreen can be used externally, SPF should be above 30.
Discoloration agents: various discoloration agents can be used externally, such as arbutin, hydroquinone, etc.
3. Oral medication: including vitamin C, vitamin E and traditional Chinese medicine, etc.
Seven, what are the treatment principles of fractional laser?
For the treatment of deep wrinkles or scars, large energy, deep penetration and low density dots are required. Clinicians must adjust the parameters appropriately according to the patient’s disease characteristics, requirements and response to treatment to achieve the best results with minimal damage. For Asian populations prone to pigmentation complications, it is recommended to choose multiple treatments with small spots, slightly lower energy and low fractional density.
Eight, how many sessions of fractional laser treatment are needed? What are the intervals?
The number of fractional laser treatments is directly proportional to the severity of the lesion, and fractional laser treatment must be repeated several times, generally 3-5 times as a course of treatment. Each treatment interval is 4-8 weeks, and the best treatment effect is 3-6 months after treatment.
Nine, who is not suitable for fractional laser?
The following people are not suitable to do.
1.Keloid people.
2.People who are prone to hyperpigmentation or abnormalities.
3.Patients with mental illness and those who have high expectations for treatment.
4.People with active vitiligo and psoriasis.
5.Persons with active infection after surgery.
