What is the Difference Between Papules and Pustules?
🆚 Go to Comparative Table 🆚The main difference between papules and pustules lies in their appearance and the presence of pus. Both are inflammatory forms of acne, but they have distinct characteristics:
- Papules: These are solid, inflamed bumps in the skin that do not have a white or yellow pus-filled tip. They are usually cone-shaped, smaller than one centimeter, and may be the same color as your skin or red, brown, or purple. Papules are caused by excess oil in the skin, bacteria, hormones, and some medications.
- Pustules: These are inflammatory pimples that have a white or yellow pus-filled tip. Pustules form when a papule becomes infected, causing the body's immune response to send white blood cells to fight the infection. As the white blood cells die, they turn into pus and protrude from the pore.
Papules can develop into pustules, and both are considered moderate to severe forms of acne when they occur in significant numbers. Treatments for papules and pustules include over-the-counter and prescription medications, but if these do not work after a few weeks of use or if other symptoms arise, a dermatologist's consultation may be necessary.
Comparative Table: Papules vs Pustules
Papules and pustules are both types of inflammatory acne, but they have some differences in their characteristics:
Feature | Papules | Pustules |
---|---|---|
Definition | Small, inflamed bumps without a pus-filled tip (raised bumps, closed pore, small size, inflamed skin on/around bump) |
Raised bumps with a white or yellow pus-filled tip, formed when a papule comes to a head (raised bumps with a white/yellowish center, closed or open pore) |
Size | Typically less than 5mm | Varies, but generally larger than papules |
Pain | Painful | Painful or tender |
Causes | Excess oil in the skin, bacteria, hormones, and some medications | Excess oil in the skin, bacteria, hormones, and some medications |
Treatment | Over-the-counter and prescription medications | Over-the-counter and prescription medications |
Papules are usually considered mild acne, while frequent clusters of papules may be classified as moderate or severe acne. Pustules, on the other hand, are a more advanced stage of acne, forming when a papule develops a pus-filled tip. Both papules and pustules are treated with similar medications, and it is essential not to pick or pop them to avoid spreading bacteria.
