http://www.krserum.com/beauty-and-personal-care-products/face-cleanser/ Blackheads are mainly caused by excessive keratinization at the openings of the sebaceous glands and hair follicles, which block the pores. After puberty, the patient鈥檚 increased levels of androgens lead to increased sebum secretion, and the increased sebum secretion will cause a large amount of free fatty acids to be produced under the action of bacteria. Free fatty acids will further stimulate the hyperkeratosis of the hair follicle sebaceous gland opening, and eventually the channel at the hair follicle sebaceous gland opening will be blocked, and the contents of the hair follicle sebaceous gland opening will not be easily discharged, so blackheads are formed. The wrong way removing blackhead will finally damage skin. 1:Rub with salt: it is difficult to control while affecting skin to result in large pores. 2: Squeeze with hands:Unsanitary ,easy to cause the mark; 3:Needle-prickling: it is more likely to damage your skin.
