Acne

 Acne is a common skin condition that causes pimples to form. It develops when hair follicles become clogged with oil and dead skin cells. Bacteria can then thrive in this environment, causing inflammation and infection.

Here's a breakdown of the cause and effect of acne:

Causes

• Excess oil production: Androgens, hormones that increase during puberty, stimulate the oil glands in your skin to produce more sebum (oil). This can clog pores.
• Hair follicles clogged by oil and dead skin cells: When sebum mixes with dead skin cells on the surface of the skin, it can form a plug that blocks the hair follicle.
• Bacteria: A type of bacteria called Propionibacterium acnes (P. acnes) lives on the skin. When the pores become clogged, P. acnes bacteria can multiply and worsen inflammation.

Effects

• Whiteheads: These are small, white bumps that form under the surface of the skin.

• Blackheads: These occur when the clogged pore opens to the surface and the sebum plugs are exposed to air, oxidizing and turning black.

• Papules: These are small, red bumps that feel tender to the touch.

• Pustules: These are similar to papules but have pus at their tips, which is a white or yellow collection of white blood cells and dead skin cells.

• Nodules: These are large, solid, painful bumps that lie deep within the skin.

• Cysts: These are the most severe form of acne. They are large, pus-filled lesions that can cause scarring.

Scars

Acne itself doesn't cause scars, but severe acne, especially cystic acne, can lead to scarring. This happens when inflammation damages the deeper layers of your skin.

Other effects

Acne can have a significant impact on a person's self-esteem and quality of life. It can cause emotional distress, social anxiety, and depression.
