One of the most important things to consider is how to get rid of the pimples
Grinding is also known as dermabrasion, which is a method of removing the epidermis and papillae of the lesions with an abrasive head to improve the appearance of the skin. This method can effectively treat small post-acne scars, large freckles, small pockmarks after smallpox or chicken pox, rosacea, milia, sebaceous nevus, lighter tattoos and pigmented dust in the skin, sweat duct tumors and other cosmetically disruptive dermatological conditions. Among them, the effect is most ideal for post-acne small scars, smallpox pits and freckles in people with white skin color.
The use of grinding cosmetic surgery to treat shallow acne scars and freckles, a time that can be more satisfactory results; but for smallpox, chicken pox scars and deeper acne scars need 2-3 treatments in order to have better results. Some people require a grinding, is unrealistic, because each grinding depth of the skin is limited, generally can not exceed 0.5-0.7 mm, or grinding too deep damage to the dermis, after the healing will still leave scars.
Cosmetic skin resurfacing is not as simple as people think, although there is no need for general anesthesia, but the operation must be carried out in a sterile operating room. In addition to wearing a surgical gown and cap and a mask, the doctor also needs to wear large square-framed eyeglasses to prevent the liquid that spins up when the machine is turned on from splashing into the eyes. There are a variety of instruments used for skin abrasion, the most commonly used being a dental drill with different types of steel grinding wheels. This type of machine is less laborious to use and can grind skin lesions to a considerable depth. This type of grinding is a delicate and precise skin procedure. While the grinding wheel is flying around, just like a milling machine turning and milling metal parts, the assistant needs to use a syringe of oil to take saline drops to the ground area to prevent localized skin from heating up and causing cellular damage. If it is after the explosion injury caused by the skin retained iron filings, cinders and other foreign objects, but also should be carefully picked out of the needle. Cosmetic resurfacing should both abrade the old skin lesions and protect the good skin. It is important that the depth of grinding should be taken into account, too shallow can not remove the skin lesions, pigment, and can not achieve the therapeutic purpose, too deep will damage the dermis, and scars will still appear in the future. Therefore, the skin should be smooth and beautiful through grinding.
After the skin grinding, the facial skin after grinding is usually wrapped with petroleum jelly oil gauze, sterile dressings, and stay in the sterilized ward for about 10 days. During this period there may be a noticeable itching sensation, which is a sign of skin healing. When the oil gauze is removed after 10 days. The skin then takes on a fine, moist, beautiful pink color.
Some people in the postoperative effect is very ideal, and in half a month, the face of the skin gradually turned light brown, this is the reaction of hyperpigmentation, the vast majority of people through the appropriate prevention and treatment can be in six months to a year to return to natural.
Because of the grinding surgery to remove the epidermis, like a skin abrasion, it will not leave a scar on the skin after the healing process; however, if there is an infection or the grinding is too deep, it will damage the dermis, which will cause different degrees of scars on the skin. Therefore, when doing this kind of surgery, you must choose an experienced doctor to carry out, so as to ensure the effect of the surgery.
Two, how long does it take to recover after grinding
After grinding, you have to wait for the newborn epithelium to completely cover the wound in order to heal, so the deeper the grinding, the longer the healing time, and in general, 8-9 days after the grinding operation can be healed.
Three, grinding should pay attention to what
Just after the grinding operation should pay attention to prevent infection, protect the wound and take antibacterial drugs. After healing should pay attention to sunscreen, can wear sun hat and apply sunscreen; do not contact photosensitizer or take photosensitive drugs (tetracyclines, certain hormones, etc.). In addition, a larger dose of vitamin C can be taken after surgery to reduce hyperpigmentation.
Four, grinding after the complications
Grinding after the common complications are: hyperpigmentation, keloid hyperplasia, secondary infection and cornrows.
1, hyperpigmentation should be prevented, but even with good protection, more than 70-90% of the Oriental people will still have hyperpigmentation, over time, the pigmentation will gradually fade, about 3-18 months after the basic subside.
2, non-keloid grinding may also appear after keloid hyperplasia, but the general area is small, if it appears, can be taken under the scar injection of drugs to make it atrophy, and again grinding can also achieve better results.
3, once the discovery of postoperative infection, available antibiotic-containing saline wet dressing, and strengthen the use of antimicrobial drugs, as long as timely measures to control, generally will not cause serious consequences, affecting the efficacy of treatment.
4, most of the cornu rashes can subside on their own, can not subside the feasibility of the second shallow grinding.
