Scarring after a fall, i.e. post-traumatic scarring, can be intervened through general treatment, medication, medical aesthetic means and surgical treatment. 1. General treatment: strengthen sunscreen to reduce hyperpigmentation; balanced diet and nutrition, eat more food rich in vitamins and high quality protein to promote collagen regeneration. 2. Medication: If proliferative scarring can be treated with local injection of glucocorticoids such as Triamcinolone acetonide, which can reduce inflammatory mediators as well as promote scar tissue atrophy, thus achieving the effect of fading scars. After the use of drugs, some patients may have local skin atrophy, capillary dilation and other adverse reactions. 3. Medical aesthetic means: such as photorejuvenation, fractional laser, micro-needle and other measures, which are also helpful in removing scar. 4. Surgical treatment: If the scar is large in size and more serious in degree, surgical excision treatment can also be considered. If you have a scar after a fall, you should go to the dermatologist in time and follow the doctor’s instructions for appropriate treatment.
