Salicylic acid resurfacing works on the surface of the skin by exfoliating the epidermis and inducing the reconstruction of the skin’s surface and dermal structure, so salicylic acid resurfacing is able to shrink pores. Salicylic acid is a weak, fat-soluble acid that penetrates deep into the pores through the oil-secreting sebaceous glands, dissolving the old stratum corneum inside the pores, improving pore clogging, and inhibiting sebaceous gland secretion. Therefore, salicylic acid resurfacing can make the skin firmer and achieve the purpose of shrinking pores. It is important to note that people with sensitive skin may experience adverse reactions such as redness, tingling, pulling and burning sensations when undergoing salicylic acid skin resurfacing. Patients with salicylic acid skin resurfacing needs should go to the dermatology department of a regular hospital and under the guidance of a specialist for standardized treatment.
