Introduction
In general, scars refer to cicatrix. The time required for scar softening injections to take effect depends on the specific situation. If the patient has a good constitution, the effect can usually be seen within one week; however, for those with a scarring predisposition, it may take 2–3 weeks or even longer to observe results. Scar softening injections are not suitable for all types of scars, and long-term use may cause adverse reactions such as hypopigmentation.
Generally speaking, scars refer to cicatrix (fibrous tissue replacing normal skin after injury). The time required for scar-softening injections to take effect depends on the specific circumstances. If the individual has a good constitution, effects may be noticeable within one week; however, for individuals with a scar-prone constitution, it may take 2–3 weeks or even longer before any effects become visible. Detailed analysis is as follows:
Scar-softening injections usually refer to corticosteroid medications, such as dexamethasone sodium phosphate injection, triamcinolone acetonide acetic acid injection, and betamethasone sodium phosphate injection. These medications inhibit fibrous tissue proliferation, thereby softening and reducing the size of scars. For individuals with better physical condition and faster metabolism, effects may appear within about one week. This is because most people may feel localized changes in the scar 3–5 days after receiving the injection, and more noticeable softening effects may gradually appear within one week.
However, for individuals with a scar-prone constitution, it may take 2–3 weeks or even longer to observe effects. This is because individuals with such a constitution generally have weaker recovery abilities and slower metabolism, which results in longer time required for the treatment to show effects.
Scar-softening injections are not suitable for all types of scars, and long-term use may lead to adverse reactions such as hypopigmentation and telangiectasia (dilation of small blood vessels). Therefore, treatment must be conducted under the guidance of a doctor, and self-administration of medication should be avoided.
