Why do pimples appear overnight

The change of environment — the sun, heat, and humidity — can trigger acne. Sunscreens have two types of active ingredients. Chemical agents that absorb into the skin and protect against harmful ultraviolet rays, and physical agents also called mineral sunscreens that sit on the surface to create a sun shield.

Acne vulgaris manifests as various types of skin blemishes, including whiteheads, blackheads, papules, and pustules.

Whiteheads occur when skin cells, oil, and bacteria combine to create a white tip of oil-skin mixture. A whitehead looks like a small pimple, but the area around it will not be inflamed and red.

Blackheads are also not inflamed. They form when the plug that clogs the pore sits at the top surface of the skin. Blackheads are not dirt stuck in your pores. A pimple is a clogged pore that has become infected. The infection makes a white pus-filled tip on top of the affected pore. The area around the infected pore can become inflamed, red, and sensitive.

Your skin is covered in millions of tiny little wells, or pores, that sit at your hair follicles. Pores connect the surface of your skin to an underlying gland called the sebaceous gland. This gland produces an oily substance called sebum. Sebum is released continually, in small amounts, into the hair follicles and skin. Dead skin cells are also carried up with the sebum so they can be washed away. Occasionally, the sebaceous gland produces too much sebum.

The overflow of oil can clog the pore. The excess oil and dead skin cells form a plug in the gland. This pore becomes clogged with sebum, oil, and possibly bacteria. The bacteria can multiply. These bacteria can lead to an infection, swelling, and inflammation around the clogged pore.

A white tip of pus will sometimes form at the top of the clogged pore. This creates a pimple. The American Academy of Dermatology says that blemishes fall into categories: pimples, which are small bumps with pus at the tip also known as pustules or without that pus also known as papules ; whiteheads, which are clogged pores that look white or fleshy; blackheads , clogged pores filled with debris not to be confused with dirt ; and cysts and nodules, which are those large painful lumps under the skin.
