Dermatologists Dr. Katie Rodan and Dr. Kathy Fields know that genetics, hormone levels, and stress can spike acne at any age. Acne occurs when sebum and dead skin cells block or clog pores, creating an environment where oxygen cannot get into the pore and bacteria can quickly reproduce. When your hormones fluctuate it can cause an increase in oil production that combines with dirt and dead skin cells to block your pores. Once that pore gets blocked it causes a decrease in the amount of oxygen into the skin which causes a surge in bad bacteria, throwing your microbiome out of whack. This imbalance causes your skin to react with inflammation, triggering the start of the acne cycle and the formation of acne beneath the surface of your skin. The result is inflammation and infection that leads to various levels of acne severity based on one’s unique skin.
Acne can take many forms such as:
- Blackheads – clogged pore that is open to the air and the oil becomes oxidised (causing it to turn “grey to black” or dark in appearance)
- Whiteheads – clogged pore that is closed with skin cells covering
- Papules and pustules (raised, red/yellow bumps) – closed, clogged pores where bacteria have entered and inflammation results and begins to spread
- Nodules (larger, deeper bumps) – closed, clogged pores where bacteria proliferates and inflammation is present
- Cystic acne (large, red, painful bumps that often spread; also, very deep in skin) – closed, clogged pores where bacteria proliferates and inflammation forms and often spreads.
