1.What is the difference between the first eyebrow tattoo removal and the second?
The second brow tattoo removal is done with close focus energy, farther away than the first and with more energy than the first.
2.What is the reason for the black and blue coloring of coffee eyebrows?
Coffee eyebrow is a blending pigment, which contains iron and lead ions, and it is easy to produce pigmentation in the epidermal layer of the skin. It is recommended to wash with 1064nm wavelength and then with 532nm wavelength. After a month and a half of observation, if the blue color returns, use 1064nm wash, if the red color returns, use 532nm wash.
3.Why do some red eyebrows have no reaction at all after eyebrow removal tattoo?
The red material is chemical coloring material, not plant coloring material, iron ions have reached the dermis layer to produce pigmentation, it is difficult to wash. For pure red eyebrow, it should be washed with 1064nm wavelength first, and then with 532nm wavelength after the color material is broken up by the focus energy to beat out the blood seepage point.
4.How to treat facial spots?
For southern liver spots (e.g. butterfly spots), the treatment effect is good; for shallow acquired freckles, the effect of washing is good; for hereditary deep freckles, the effect of washing is not good; for age spots, the focus washing can be used to break up and beat out the oozing blood, and the general treatment period is three courses of treatment with an interval of 45 days.
5.What is the treatment method for moles?
Just use the focus energy to beat the moles out of the blood seepage point.
6.Can I wash my “scarred body”?
Very few “scars” can be washed, and those that can be tattooed can be washed, but the results are not as good as normal skin. But the result is not as good as normal skin. Try to use large spots and small energy in the process of washing, and prohibit the use of focused energy washing.
7.Can pregnant women have eyebrow laser removal?
Pregnant women cannot have their eyebrows laser washed.
8.How and to what extent can I wash my redness?
It is not recommended to wash the red blood filaments because the hemoglobin in the blood absorbs the light of 532nm wavelength, and if it is not diffused in time, it will form “purpura” and cause the failure of the procedure.
9.What is removery tattoo removal?
Lasers can produce high-energy, focused and precise monochromatic light with certain penetration and targeting, which acts on the diseased tissues of the human body to produce high heat locally without destroying the surrounding normal tissues. Laser cosmetology makes use of this characteristic to remove or destroy the target tissues and achieve the purpose of cosmetology treatment.
10.What is the superiority of permanent eyebrow removal?
Compared with the traditional method, laser eyebrow cleaning has less bleeding, less pain, high quality of operation, short operation time, less scars and less recurrence. The laser beam is fine, not easy to hurt the surrounding normal tissues, the blood vessels have “thermal welding” effect; thermal coagulation effect makes the nerve endings lose pain, less damage to the surrounding tissues; bloodless surgical field of vision is clear; the energy is large and centralized; follow the “principle of selective absorption effect”, does not cause irreversible damage to normal tissues, and the treatment of lesions is thorough.
11.What is “selective photothermal effect”?
When the laser reaches the lesion site through the normal tissues of the human body, so that the absorption coefficient of the lesion tissue to the laser is greater than that of the normal tissue, and the greater the contrast, the better, and at the same time, the laser pulse width is less than the thermal relaxation time of the lesion target, so that it does not injure the normal tissues when destroying the lesion tissues, i.e., it achieves the therapeutic purpose through the appropriate pulse width, wavelength and energy.
12.What is “thermal relaxation time”?
It is also called “thermal dissipation time”, which indicates the time required for a substance to drop from the highest temperature to half after it has been transformed into heat by energy input, and it can be interpreted as the shortest time required when the skin is subjected to heat and burns in terms of skin.
13.How to grasp the energy density of a laser?
Laser energy density E = laser energy Q/0.787 × spot size D. Energy density E is inversely proportional to spot diameter. In practice, the dosage should be adjusted from small to large according to the skin condition (skin color, thickness, roughness, etc.), with the large spot followed by the small spot; pay close attention to the change of skin color in normal parts, and it is appropriate to make the epidermis appear pink when laser irradiation is applied to the treatment of vascular dermatosis; change the dosage according to the color depth of the pigment; and the laser beam must be perpendicularly directed to the epidermis at all times.
