At first glance, all skin breakouts may look the same. When you see a red bump on your face or body that hurts or is swollen, you probably think it's "just a pimple." But not all blemishes are the same. Some are small and go away in a few days, while others are deeply embedded in the skin and cause long-lasting pain, swelling, and even permanent scarring.
At OC MedDerm - Irvine dermatology clinic, we frequently see patients from across Orange County confused about whether their breakout is a cyst, pimple, or zit.
People often use the words "cyst," "zit," and "pimple" to mean the same thing. But they are different types of skin lesions that differ in depth, severity, cause, and suggested treatment. These differences go beyond just medical ones. Knowing what kind of breakout you have can help you treat it properly, keep it from getting worse, and stop new breakouts from forming in the same place.
We'll go over what each of these words means, how they are similar and different, and how to tell what kind of blemish you have in this section.
Are All Skin Bumps the Same?
No, not all breakouts are the same. Even though a lot of blemishes look the same on the surface, they are different in depth, severity, cause, and how they respond to treatment.
To start, let’s break down what each term actually means.
Zit
"Zit" is a slang word. People often use it to talk about any small red bump on the skin, especially a pimple that has gotten bigger or filled with pus. Even though it doesn't have a medical definition, people often use it to talk about acne on the surface, like whiteheads or pustules.
Pimple
"Pimple" is a general term for any kind of acne lesion that happens when pores get clogged. When dead skin cells, sebum (oil), and bacteria build up in a hair follicle, they can cause pimples. Pimples can be whiteheads, blackheads, papules, pustules, or nodules. They can be different depths, looks, and how they respond to treatment.
Cyst
A cyst is a severe type of acne. When a pore gets very clogged and infected, it causes a swollen, painful lump to form under the skin. Cysts are full of pus and other inflammatory substances, and they can last for weeks or even months. Cysts are different from regular pimples or zits in that they almost always need medical attention and have a high risk of leaving scars.
Key Difference between Zit, Pimple, and Cyst
Let’s compare these breakouts directly for clarity:
| Feature | Zit | Pimple | Cyst |
| Definition | Informal term for inflamed blemish | General acne lesion | Deep, infected lump under the skin |
| Depth | Surface-level | Surface or slightly below | Deep in dermis, under multiple skin layers |
| Pain Level | Mild or none | Mild to moderate | Moderate to severe, often throbbing |
| Appearance | Red bump, whitehead, or pus-filled | Can be red, white, or dark | Large, swollen lump; no head |
| Pus Presence | Often | Often | Usually thick pus; may not drain |
| Healing Time | A few days | Days to a week | Weeks or longer |
| Scarring Risk | Low | Low to moderate | High without treatment |
| Treatment Options | OTC creams, salicylic acid, spot care | OTC or mild prescriptions | Prescription meds, injections, drainage |
How to Identify What You Have
Knowing how these lesions act can help you avoid worsening this problem. Here's how to understand what's on your skin:
- Is it little, red, and gone in three to five days?
You probably had a regular zit or a surface pimple. These are often caused by pores that are clogged or mild inflammation, and topical acne treatments usually work on them.
- Is it swollen, painful, and hasn't come to a head yet?
That's a sign of a cystic lesion. When the infection goes deeper, cysts form. Unlike regular pimples, they don't usually drain. They can feel like hard or soft lumps under the skin and can take weeks to heal.
- Does it have a white or yellow center and break easily?
This is a classic pustule, which is a type of pimple that people often call a "zit." With the right care, they may heal quickly, but If you pop them they can get infected.
Types of Pimples and How to Identify Them
A pimple isn't just one kind of skin bump. Dermatologists put pimples into groups based on how they form, whether they are inflamed, and how deeply they affect the skin. Knowing what kind of pimple you have can help you treat it better and avoid making it worse or leaving scars.
Here are the six most common types of pimples, how they look, and what they might mean about the health of your skin.
1. Whiteheads
What they are: When a pore gets clogged with oil and dead skin cells but stays closed at the surface, it becomes a whitehead or closed comedone. The bump looks white or flesh-colored because the blockage is trapped under a thin layer of skin.
What they look like: Small, round bumps that are a little raised and have a white top. They don't hurt and aren't red.
Best treatment: Whiteheads usually respond well to salicylic acid, gentle exfoliation, and non-comedogenic skin care products. Don't pick at them, because this can push bacteria deeper into the skin.
2. Blackheads
What they are: Blackheads, or open comedones, form when oil and dirt get stuck in pores. But in this case, the pore stays open to the air. The dark look isn't because of dirt; it's because of oxidation, which happens when sebum comes into contact with oxygen.
What they look like: Flat or slightly raised dark spots that are most common on the forehead, chin, and nose.
Best treatment: The best treatment is to look for exfoliants that have glycolic acid or salicylic acid in them. Clay masks and pore strips can help loosen the plug for a short time, but long-term treatment works better.
3. Papules
What they are: Papules are inflamed pimples that form when bacteria, oil, and dead skin cells build up and break down the wall of a pore. This makes the bump red and swollen, but you can't see any pus in it.
What they look like: Bumps that are firm, red, and often tender that stick out from the skin but don't have a head.
Best treatment: Don't try to pop papules. Use topical retinoids or benzoyl peroxide instead. These are both anti-inflammatory. If your papules don't go away, you might need to use prescription creams to reduce swelling and stop scarring.
4. Pustules
What they are: When inflammation keeps going and pus builds up inside the pimple, pustules form. This is what most people think of when they hear the word "zit."
What they look like: The bottom is red and the middle is white or yellow. They can hurt, but not as much as cysts.
Best treatment: Benzoyl peroxide or sulfur spot treatments can help dry up the pus. If you keep getting pustules, a dermatologist may suggest a short course of topical antibiotics.
5. Nodules
What they are: Nodules are big, painful pimples that form deep under the skin. Nodules don't have pus in them and don't usually come to a visible head like pustules or whiteheads do. Hormonal changes or severe bacterial infections are common causes of them.
What they look like: Lumps that are hard and round and feel like marbles under the skin. They are usually red and hurt, and there is no opening on the surface.
Best treatment: Over-the-counter products don't work well on nodules, so the best treatment is usually treatment involving taking prescription oral medication or seeing a dermatologist. If you don't treat them, you are more likely to get scars.
6. Cysts
What they are: Cysts are like nodules in terms of depth and severity, but they are usually softer and have pus in them. When a pore gets clogged and infected deep in the skin, it causes a strong inflammatory response that leads to these.
What they look like: Big, red, swollen bumps under the skin. They might hurt or feel tender, and unlike pustules, they don't usually break open on their own.
Best treatment: The best way to treat cysts is to see a professional. Dermatologists can give them corticosteroids through an injection to reduce swelling, drain them in a clean way, or give them antibiotics to take by mouth. Isotretinoin may be needed for severe or recurring cystic acne.
How These Types Fit Together
People often call any breakout a "pimple" or "zit," but the six types listed above are very different in the severity they are and how they need to be treated.
Here's a quick breakdown:
| Pimple Type | Inflamed? | Contains Pus? | Depth in Skin | Risk of Scarring |
| Whitehead | No | No | Surface (epidermis) | Low |
| Blackhead | No | No | Surface | Low |
| Papule | Yes | No | Mid-layer | Moderate |
| Pustule | Yes | Yes | Mid to upper layer | Moderate |
| Nodule | Yes | No | Deep (dermis) | High |
| Cyst | Yes | Yes (thick pus) | Deep (dermis + subcut.) | Very high |
When to See a Dermatologist
Many patients in Irvine and Orange County seek treatment when painful cysts do not respond to over-the-counter acne products.
If home remedies and over-the-counter treatments aren't working for your skin, professional cystic acne treatment in Irvine can help prevent scarring and lower the emotional stress that comes with living with acne for a long time.
Consider Seeing a Dermatologist If:
- If you often have painful, deep breakouts, you might want to see a dermatologist.
- Your skin has scars or spots that are different colors.
- The lesions last longer than ten to fon urteen days.

Dermatologists can help with a lot of different things, like topical retinoids, antibiotics, hormonal treatments, chemical peels, light therapy, and more personalized care.
Final Thoughts
Skin breakouts are frustrating, but understanding what you are dealing with gives you the power to treat it effectively. Zits and minor pimples are often short-term and manageable. Cysts, however, are deeper, more painful, and carry a higher risk of scarring. They require a different level of care and often benefit from professional treatment.
Instead of guessing or self-diagnosing, speak with an expert who understands the differences and can help you heal your skin without making things worse.
Skin breakouts are frustrating, but understanding what you are dealing with gives you the power to treat it effectively. Most of the time, zits and small pimples go away on their own. Cysts, on the other hand, are deeper, hurt more, and are more likely to leave scars. They need a different level of care and often do better with professional help.

Frequently Asked Questions (FAQs)
What is the difference between cystic acne and a pimple?
Cystic acne and pimples differ in depth and severity.
A pimple forms near the surface of the skin when pores clog with oil and bacteria. Cystic acne develops deep beneath the skin, forming large, painful lumps that may not come to a head. In Irvine and Orange County patients, cystic acne is more likely to scar and often requires dermatologist treatment.
Are cystic acne cysts harder to treat than pimples?
Yes, cystic acne is much harder to treat than regular pimples.
Over-the-counter products often help mild acne but are usually ineffective for deep acne cysts. Cystic acne treatment in Irvine typically requires prescription medications or in-office procedures performed by a dermatologist to reduce inflammation and prevent scarring.
Can cystic acne cause permanent scars?
Yes, untreated cystic acne can cause permanent scars.
Because cysts damage deeper layers of skin, they frequently lead to pitted scars, dark spots, or uneven texture. Early treatment by a dermatologist in Orange County significantly reduces scarring risk and improves long-term skin health.
When should I see a dermatologist for acne in Irvine?
You should see a dermatologist for acne in Irvine if:
- Acne is painful or deep
