If you are afraid of scarring after skin trauma, it is best not to eat some spicy and irritating foods and avoid contact with water. Eating spicy and irritating food will lead to poor wound healing, and contact with water will lead to scarring, so it must be avoided. You can use topical recombinant human epidermal growth factor gel to promote rapid skin healing, and after healing, you can give Conrad Paste topical with Xyrtec cream to inhibit the proliferation of scar. Sunlight exposure can cause post-inflammatory hyperpigmentation or post-inflammatory hypopigmentation in the healing area. If an augmented scar is formed, topical retinoic acid cream or glucocorticoids can be given topically in small amounts to inhibit the augmentation of the scar.
