White particles on the face, such particles are likely to be whitehead acne, or papulopustular acne. This reaction is generally due to the secretion of sebum by the sebaceous glands. Due to the hyperkeratosis of the skin’s follicle opening or sebaceous gland opening, the sebum cannot be effectively discharged from the skin surface, resulting in the formation of concentrated, so that white particles may appear, so this white particle is also called fatty grains. For this symptom, appropriate topical medication is usually sufficient. Generally most of them can be applied topically with adapalene gel 2 times/day, or 5%-10% sulfur ointment can be used. If it is very stubborn, you can also use an acne squeezer to squeeze out these white particles.
