Whiteheads, or closed comedones, are follicles blocked by sebum and dead skin cells where the pore remains closed. Because the plug is sealed under a thin layer of skin, treatment requires ingredients that promote cellular exfoliation (like AHAs) and regulate keratinization without causing barrier damage.

No. Because whiteheads are closed, squeezing them without a sterile opening tears the skin, pushing bacteria deeper, causing red painful pimples, and leading to permanent dark marks or scars.
Alpha-Hydroxy Acids (like Glycolic Acid or Lactic Acid) exfoliate the surface layer of dead skin, while Retinoids help normalize cell turnover to prevent the pore from getting sealed shut.
If a whitehead becomes infected with C. acnes bacteria or is irritated by touching/picking, the body responds with inflammation, turning the clogged pore into a red, pus-filled pimple.
