Pimples, Blackheads & Whiteheads: What’s The Difference?

Pimples, blackheads and whiteheads are common skin concerns, yet these terms are often used interchangeably. While they can all appear on blemish-prone skin, they form in slightly different ways.

Blackheads and whiteheads develop when pores become clogged with oil, dead skin cells and debris. Pimples can appear when a clogged pore becomes visibly irritated or inflamed. Understanding the differences can help you choose skincare ingredients that support clearer-looking skin.

What Causes Pimples, Blackheads and Whiteheads?

Breakouts can develop when pores become blocked with excess oil, also known as sebum, dead skin cells and debris. When these elements build up inside the pore, they can contribute to congestion, visible blemishes and uneven-looking skin.

The main contributors behind pimples, blackheads and whiteheads are often excess oil production, dead skin cell build-up, impurities becoming trapped inside congested pores and visible irritation. When these factors combine, blemishes can develop.

Hormonal fluctuations, genetics and certain skincare products can also influence how often breakouts occur.

Types of Blemishes: Understanding Different Breakouts

The type of blemish that forms depends on how the pore becomes clogged and whether visible irritation is present.

What Is a Pimple?

A pimple is a visible blemish that can develop when a clogged pore becomes irritated. Pimples often appear as red bumps or pus-filled spots and may feel tender to the touch.

What Are Whiteheads?

Whiteheads, also known as closed comedones, form when a pore becomes clogged but remains closed at the skin’s surface. The trapped oil and debris stay beneath the skin, creating a small white or flesh-coloured bump.

What Are Blackheads?

Blackheads, or open comedones, occur when the clogged pore remains open. The trapped oil inside the pore reacts with oxygen in the air, which causes the dark appearance associated with blackheads.

Blackheads commonly appear on the nose, chin and forehead, where oil production tends to be higher.

What Are Deep, Persistent Blemishes?

Some blemishes develop deeper beneath the skin and may appear as larger, more noticeable bumps. These can feel tender or uncomfortable and may take longer to settle than surface-level blemishes.

If breakouts are persistent, painful or leaving visible marks, it is best to speak to a dermatologist or healthcare professional for personalised advice.

Blackhead vs Whitehead: What’s the Difference?

Both blackheads and whiteheads develop from clogged pores. The difference is whether the pore stays open or closed.

Whiteheads form when the pore closes, trapping oil and dead skin beneath the surface. Blackheads occur when the pore remains open, allowing the material inside to oxidise when exposed to air.

In simple terms, a whitehead is a closed clogged pore, while a blackhead is an open clogged pore. The dark colour of a blackhead is not dirt; it is caused by oxidation.

Zit vs Pimple: Is There a Difference?

“Zit” is simply a slang term for pimple that became popular in the 1960s. In practice, the two terms refer to the same type of visible blemish.

How to Help Reduce the Appearance of Whiteheads and Blackheads

Avoid squeezing blemishes whenever possible, as this can increase irritation and raise the risk of visible marks.

Instead, maintain a consistent skincare routine designed to help keep pores clear. Ingredients commonly used in skincare for blemish-prone skin include salicylic acid, which helps exfoliate inside the pore, and retinoids, which support natural skin renewal, which helps to improve the appearance of skin texture overtime.

A non-comedogenic moisturiser can also help maintain hydration without clogging pores.

A Three-Tier Approach to Supporting Clearer-Looking Skin

Managing breakouts often involves more than one step. A balanced approach that includes diet, supplements and topical skincare can help support overall skin health.

Diet

What you eat may influence the appearance of your skin. Dr. Perricone has long advocated for an inside-out approach to skincare through nutrient-dense foods rich in antioxidants, healthy fats and high-quality proteins.

His 28-Day Anti-Inflammatory Diet focuses on foods that support overall skin wellness.

Supplements

Nutritional supplements can complement a balanced diet and consistent skincare routine by helping to support overall wellbeing and the visible health of the skin.

Ingredients such as antioxidants, essential fatty acids and key vitamins are often used in supplement formulas designed to support skin health from within. As with any supplement, follow the product directions and seek advice from a healthcare professional if you are unsure what is right for you.

Topical Skincare

Topical skincare is an essential part of caring for blemish-prone skin. Cleansers, treatments and moisturisers formulated for congestion can help keep pores clear while maintaining skin balance.

Our Blemish Relief collection includes targeted skincare designed to help refine the appearance of blemish-prone skin and support a clearer-looking complexion.

Together, these three elements can help support a balanced approach to clearer-looking skin.

If breakouts persist despite a consistent routine, consulting a dermatologist can help determine the most appropriate treatment approach.
