How does the scar left after the operation fade?
1. External use medicine The general public is looking forward to a magical scar-removing ointment that can make scars disappear without a trace. However, because scar is a normal connective tissue used to heal wounds, it will inevitably form and exist at any wound. The external ointment applied to the scar can only slightly moisturize, soften, stop the scar, diminish inflammation and dilute the pigment, thus improving and beautifying the appearance of the scar, but it can't really "remove the scar". Scar ointment can be divided into ordinary moisturizing ointment, anti-inflammatory ointment containing steroids, moisturizing and softening ointment containing silica gel, and melanin-removing ointment used to dilute pigmentation. As for the fruit acid for beauty, since it can improve the skin, can it smooth the acne scar on the ugly face? In fact, fruit acid, especially at high concentration (10%), has the characteristics of stimulating dermal collagen proliferation and restoring skin elasticity, thus flattening the uneven scars of acne, but it will only have an effect after several months of continuous use, and it is limited to shallow scars and has no effect on deep scars. 2. Scar grinding operation The principle of scar grinding operation is to smooth the uneven scar epidermis, and then grow a new epidermis through the process of wound healing, so that the scar becomes blurred and the appearance is improved. However, the scar can only be limited to a safe depth, and there is nothing you can do about it if it is too deep. Other methods are needed to improve scars or comprehensive treatment. Scar grinding operation is also divided into depth. The advantages of shallow scar grinding are that it does not need anesthesia, the wound recovers quickly, and the side effects are small, but it can only improve the shallow scar, and it must be carried out many times to have an effect. It is a common method to polish scars by high-speed jet of crystal sand. Deep scar grinding is suitable for improving deep scars. Use a high-speed rotating metal brush or diamond grinding to smooth the scar. Or use CO2 laser to heat and evaporate the scar tissue to make the scar fade. However, the wound care after deep scar abrasion is troublesome and takes a long time to recover. In the recovery period, there may be a few months of scar redness or pigmentation. If the deep grinding scar is not done well, it may aggravate and worsen the scar, so be prepared psychologically before proceeding. 3. Laser treatment There are two kinds of lasers used in scar treatment: growth scar and depression scar. Growing scars are large, convex and often reddish. For the growing scar, heme laser with a wavelength of 585nm or colored light with a wavelength of about 585nm can be used to shrink the microfilament blood vessels in the scar. Repeated treatment can shrink the scar and reduce the red mark. The sunken scar is caused by the reduction and disorder of collagen and elastin under the skin, and the concave-convex hole on the face is the best representative. In the past, the improvement methods were inseparable from peeling and fruit acid treatment, and the effect was often unsatisfactory. At present, the latest method is to stimulate the regeneration and rearrangement of collagen under dermis by non-invasive long-wave 1320nm laser or colored light, so as to fade the concave-convex surface of scar. The treatment is divided into several times, and because there will be no epidermal wounds, there is no need to take time off to rest and recover. 4. Surgery According to personal circumstances, plastic surgeons will choose cutting, suturing or skin grafting to improve and correct scars. Cutting method is suitable for small concave-convex scars, such as chicken pox scars, ice cone pockmarks, too thick or sunken scars. The surgical method is to remove the scar first, then peel off the skin from the subcutaneous tissue to reduce the tension of the wound, and then sew it carefully to make it a beautiful and young linear scar. In some cases, you can also change the method of scar or zigzag suture to make scar more difficult to find. It is better to cooperate with scar grinding around after operation.
