Why Does Comedonal Acne Cause Blackheads?

A pore contains a hair follicle and an oil-producing gland. In comedonal acne, sticky oil and dead cells collect inside the follicle instead of moving out normally. When the pore opening stays exposed, the plug meets air and darkens through oxidation. The dark colour is not simply dirt, so scrubbing harder does not remove the underlying tendency to form plugs. Blackheads often appear on the nose, forehead, chin, chest, or back, where oil production may be higher.

Wash gently and avoid rough scrubs, squeezing, or using several strong products at once. Non-comedogenic moisturiser and sunscreen can support the skin barrier without adding a heavy oil layer. A clinician may recommend a topical retinoid or another pore-unblocking treatment; these products work gradually and can irritate skin if introduced too quickly. Follow the product directions and give one routine time to show whether it suits you.

Seek medical advice if blackheads are widespread, leave marks, occur with painful inflamed spots, or have not improved with a consistent gentle routine. Professional assessment can distinguish comedonal acne from conditions that resemble clogged pores and can help choose treatment for sensitive, dry, or eczema-prone skin.

Which product is appropriate for my skin type? How often should I use it? Could my hair, makeup, or skincare products be contributing to blocked pores?
