How Blackheads Really Form — And Why Washing Doesn't Help

The most common misconception in skincare: Blackheads are caused by dirty skin. Wrong. Comedones are the result of a biochemical process — and understanding it allows you to specifically interrupt it.

What is a Blackhead anyway?

A blackhead (open comedone) forms when a pore becomes clogged with a mixture of sebum, dead skin cells, and bacterial residue. The dark color does not come from dirt — it is caused by oxidation: When the sebum plug comes into contact with oxygen, the melanin oxidizes and turns black.

The 4 Biochemical Causes

• 1
  Sebum Overproduction (Seborrhea) Triggered by hormones (androgens), stress (cortisol), and diet (sugar, dairy products). More sebum = more material for blockages.
• 2
  Slowed Cell Regeneration Dead skin cells are not shed quickly enough and mix with sebum in the pore.
• 3
  Weakened Skin Barrier A damaged barrier increases susceptibility to inflammation — pores react with increased sebum production as a protective reaction.
• 4
  Oxidation at the Pore Opening The sebum plug oxidizes in the air — that's the black color. Not dirt. Chemistry.

Why Washing and Squeezing Don't Work

Aggressive cleansing removes sebum from the surface — but at the same time stimulates the sebaceous glands to overproduce as a compensatory reaction. Squeezing empties the pore short-term, but leaves behind micro-inflammations that accelerate the next blockage.

The Right Solution: BHA + Niacinamide

The DERMAROOT BHA + Niacinamide Serum specifically combines both active ingredients:

• ✓
  Salicylic Acid (BHA) — dissolves blockages in the pore, exfoliates from within, reduces existing blackheads from week 1.
• ✓
  Niacinamide — regulates sebum production, reduces pore size, strengthens the barrier against new blockages.
