How acne is caused?
Acne. It’s one of the most common skin concerns in the world—yet also one of the most misunderstood.
Whether you’re facing the occasional breakout or living with persistent acne, understanding the what, why, and how of acne is the first step toward healing your skin with the right care. At HiPer Skin, we specialize in high-performance, biotic-powered skincare designed specifically for acne-prone skin—and we believe knowledge is the first step toward transformation.
What is Acne?
Acne is a chronic inflammatory skin condition that occurs when your pores become clogged with oil, dead skin cells, and bacteria. It commonly appears as:
- Whiteheads
- Blackheads
- Papules (small red bumps)
- Pustules (bumps with pus)
- Nodules or cysts (painful, deep lumps under the skin)
Acne most often affects the face, but can also appear on the chest, back, shoulders, and neck.
What Causes Acne?
1. Excess Sebum Production - Your skin naturally produces oil (sebum) to stay hydrated. But overproduction—triggered by hormones, genetics, or lifestyle—can clog pores and feed acne-causing bacteria.
2. Clogged Pores - Dead skin cells that aren’t properly shed can mix with sebum and block pores. This creates the perfect environment for breakouts to develop.
3. Bacteria (Cutibacterium acnes) - This bacteria lives on everyone’s skin. But when pores get clogged, it multiplies rapidly, leading to inflammation and pus-filled pimples.
4. Hormonal Imbalances - Fluctuations in hormones—especially androgens—can trigger more oil production and worsen acne. That’s why acne often flares during puberty, menstruation, pregnancy, or due to conditions like PCOS.
5. Inflammation - Even before you see a pimple, inflammation may already be brewing beneath the skin. Acne is, at its core, an inflammatory condition.
Types of Acne
Knowing your acne type helps you treat it effectively. Here’s a quick breakdown:
Type | Appearance | Cause |
Whiteheads | Closed clogged pores | Oil + dead skin |
Blackheads | Open clogged pores (black) | Oxidized sebum |
Papules | Small red bumps | Inflammation |
Pustules | Red bumps with white pus | Bacteria + inflammation |
Nodules | Large, painful lumps | Deep pore blockage |
Cysts | Painful, pus-filled lumps | Severe inflammation, often hormonal |
Common Acne Triggers
- Stress
- Poor sleep
- Diet high in dairy, sugar, or processed foods
- Using comedogenic skincare or makeup
- Not removing makeup properly
- Sweat and friction (hello, maskne!)
- Environmental pollutants

How is Acne Caused? The Science Behind Breakouts | HiPer Skin
We’ve all experienced it—a pimple that shows up the night before a big day, or a sudden breakout that feels like it came out of nowhere. But acne isn’t random. Every breakout has a trigger, and understanding how acne is caused is the first step to controlling it.
At HiPer Skin, we go beyond surface-level fixes. We dive into the root causes of acne so we can formulate science-led, biotic-powered solutions that actually work.
Here’s everything you need to know about what causes acne, step by step.
The Acne Formation Process: What Happens Beneath the Skin
Acne isn’t just a skin-deep issue. It begins below the surface, in a tiny structure called the pilosebaceous unit—which includes your hair follicle, oil gland (sebaceous gland), and pore.
Here’s how acne develops in 4 key steps:
🔹 Step 1: Excess Sebum Production
Your skin naturally produces oil (called sebum) to stay soft and hydrated. But in acne-prone skin, this process goes into overdrive. The sebaceous glands become overstimulated—often due to hormones—and produce too much oil.
🧬 Hormones, especially androgens (like testosterone), are a major trigger here. That’s why acne is so common during puberty, menstrual cycles, PCOS, or stress.
🔹 Step 2: Dead Skin Cells Get Trapped
Normally, dead skin cells shed off the surface of your skin. But in acne-prone skin, these cells don’t shed properly. Instead, they stick together and mix with the excess sebum, forming a sticky plug that blocks the pore.
This is how whiteheads and blackheads (comedones) are born.
🔹 Step 3: Bacteria Multiply
Once your pores are clogged, they create the perfect oxygen-free environment for a common skin bacterium:
Cutibacterium acnes (C. acnes).
This bacteria lives harmlessly on everyone’s skin—but when trapped in a clogged pore, it multiplies rapidly and triggers an immune response, leading to redness, swelling, and pus.
🔹 Step 4: Inflammation Kicks In
As your body reacts to the overgrowth of bacteria, it sends white blood cells to fight back. This immune response causes inflammation—the hallmark of acne.
Depending on how deep and severe the inflammation is, you may get:
- Papules (small red bumps)
- Pustules (pimples with white pus)
- Nodules or cysts (deep, painful lumps under the skin)
What Triggers This Process?
While the basic acne cycle is the same, various internal and external triggers can worsen or accelerate it. Here are the most common ones:
1. Hormonal Imbalances
- Puberty
- Menstrual cycle
- PCOS
- Pregnancy
- Stopping or starting birth control
- Hormones stimulate oil production. More oil = more clogged pores.
2. Stress
Stress doesn’t directly cause acne, but it raises cortisol levels, which can spike oil production and inflammation. It can also disrupt your microbiome and slow skin healing.
3. Genetics
If your parents had acne, chances are you will too. Genetics influence:
- Oil production
- Inflammatory response
- Skin cell turnover
- Hormonal sensitivity
4. Diet
Emerging research links high-glycemic diets (sugar, white carbs, junk food) and dairy (especially skim milk) to increased acne. These can influence insulin and androgen levels.
5. Skincare & Lifestyle
- Using comedogenic (pore-clogging) products
- Not removing makeup properly
- Harsh or drying cleansers that damage the skin barrier
- Wearing tight clothing or helmets (causing frictional acne or “acne mechanica”)
- Hot, humid weather or pollution
- Over-exfoliation, which can damage skin and trigger more oil production
So, Can Acne Be Prevented?
In many cases, yes—acne can be managed and reduced with the right approach.
At HiPer Skin, we design products to interrupt this acne cycle at every stage:
Control oil production with ingredients like niacinamide & salicylic acid
Prevent clogged pores with gentle exfoliators and barrier-supporting ingredients
Balance the skin microbiome with prebiotics, postbiotics, and biotic complexes
