It usually takes about 3 months to recover from the black marks left after facial picking. After facial gouging, post-inflammatory hyperpigmentation can be formed at a later stage due to the formation of local traumatic inflammation, reduction of local traumatic tissue sulfur hydrogen group, upregulation of melanocyte activity by cytokines, certain inflammatory cells, and prostaglandins, and increase of complexinase activity. There are natural melanin metabolizing enzymes in the body, which can convert melanin into amino acids, and amino acids form carbon dioxide and water under the action of amino acid oxidase, so that melanin is gradually metabolized in the body, and the black marks will gradually fade in about 3 months under normal circumstances. For the black marks left after facial gouging, you can choose to systematically use vitamin C, vitamin E, or topical hydroquinone, nonanedioic acid, and if necessary, you can choose photoelectric therapy, chemical peeling, etc., which will help accelerate the fading of the black marks.
