Acne marks caused by mites can be understood as hyperpigmentation or scarring left behind after the mite-induced localized skin tissue infection heals. Some of the hyperpigmentation usually lasts for a few months and then disappears, while some of it, along with the scarring, is permanent but can be improved by acid brushing, lasers, and other means. Inflammatory hyperpigmentation and scarring have significant individual differences in the time it takes for them to fade. Generally, some of the hyperpigmentation will fade away with normal skin metabolism in about 3 to 6 months. For those who can’t fade away, the symptoms can be improved by acid brushing and laser treatment. 1. Acid brushing treatment: Choose weak acidic chemicals such as salicylic acid and fruit acid to brush the local skin, which will help to lighten the pigmentation patches on the skin surface. 2. Laser treatment: Using the heat energy generated by laser treatment to cause thermal damage to local tissues and break down melanin particles to accelerate metabolism, and at the same time, promote the rearrangement of scar tissue structure, so as to achieve the purpose of fading hyperpigmentation and improve the appearance of keloid scars. Due to individual differences, it is recommended that patients who wish to undergo treatment go to a regular medical institution for consultation, and for specific cases, they need to consult a specialist before choosing an appropriate treatment plan.
