Whenever the body is injured, scarring occurs. From formation to stabilization, keloid scars go through two phases: the proliferative phase and the mature phase. In the proliferative stage, the color of the scar gradually becomes red, the texture becomes hard, the thickness becomes thicker and higher than the skin, and there is often a combination of symptoms such as mild itching and pain. change and reach stability. For general surgical scars, this process takes about six months. For some deeper scars, scars with skin defects on the surface or scars with poor skin alignment, this process may take longer, usually 1-2 years, sometimes 3-4 years or longer. In order to make the scar as inconspicuous as possible, it is important to intervene early to inhibit scar growth. If you wait for the scar to stabilize after six months, it will basically have little effect. There are a lot of drugs that inhibit scar growth, and they are effective in the early stage of scar application, mainly MepiCare, Scar Enemy (Senka), Barker, and Kangrebo, of which the first two are for paste and the last two are for application. In terms of principle, MepiCare, Keloid Enemy and Barker are all silicone-containing dressings/oils that use the silica gel in them to produce the effect of inhibiting scar proliferation, which is the most commonly used at present; while Kangrebo contains onion extract, sodium heparin and allantoin, which have anti-inflammatory and scar-softening effects. These medications are usually started about a week after stitch removal. The wound must be clean and dry and completely healed at the time of use, without epidermal defects, oozing or crusting, and if there is a crust on the wound, you should wait for it to fall off on its own. Because most of the scabs underneath are not fully grown skin or trauma, picking off may affect the growth of the epidermis or even the wound healing. Due to the similarity of the principle, there is no need to reapply Mepore, ScarCure and Barker. The main difference is the color and thickness. The main difference is the color and thickness of the patch. The skin care is light-skinned and the thickness is about the same as a band-aid, while the scarring is colorless and transparent and the thickness is about 3mm. For exposed areas, it is recommended to use the skin care, which is not very obvious and has a sunscreen effect. For some more hidden parts, the advantage of the beauty skin care is thin and breathable, but it is a relatively short sticker time, generally 5-7 days there is no adhesion (can be fixed with tape to continue to use, but then there may not be attached very well); and the advantage of the scar enemy is a long sticker time, about 28 days, but the disadvantage is not enough breathable, the edge is easy to roll up. Barker has an applied ointment and also a spray, which will form a protective layer on the surface of the wound after drying, and can be used in some places where there is hair or this other not easy to stick; another advantage of it is that it can be used on the face, and you can do simple makeup outside the protective layer, but you must wait for it to dry and use something with a fine texture. Complan is relatively inexpensive compared to the first three. Its anti-inflammatory effect is good for promoting wound healing and reducing scar growth, while the sodium heparin component it contains has a certain depigmentation effect. In addition to medication, it is also very important to reduce the tension on both sides of the wound as much as possible, especially in some areas that are prone to scar growth (e.g. chest) or where the tension is relatively high (e.g. extremities). The wound that has just been opened, although it seems to have grown, but in fact, its tension resistance is less than 30% of normal, it is very easy to be pulled by the tension on both sides to widen or increase. Therefore, as long as the wound condition allows, the reduction of tension should start immediately after the removal of stitches, or even after the injury or surgery. Common methods include: after the stitches are removed, you can use adhesive tape to pull the two sides of the wound together for a period of time, do as little as possible or do not do sports that may pull the wound, such as facial wounds do not cry and laugh, do not chew hard; limb wounds to minimize the movement. You can also use a variety of elastic mesh or clothing to pressurize the wound, such as wrist and knee pads, lumbar seal, elastic stockings, etc. The chest wound position is higher can be pressurized with special elastic clothing. There needs to be a certain amount of pressure, as much as possible to do 24 hours of continuous pressure. For wounds on exposed areas, there is another important point to note: sun protection, otherwise wounds are more likely to be affected by ultraviolet rays leaving hyperpigmentation, so remember to wear sunscreen when you go out. All of these anti-scar treatments need to be adhered to for at least 3-6 months until the scar stabilizes.
