Acne, medically known as acne vulgaris, is an extremely common inflammatory skin condition. It develops when pores on your face, which are tiny openings for hair follicles, become clogged with a mixture of oil and dead skin cells. This blockage can result in various types of blemishes, from small pimples to deeper, more painful lumps. It's helpful to remember that acne is a medical condition and not a reflection of personal hygiene.

In healthy skin, a natural oil called sebum is produced to keep the skin lubricated and protected. With acne, the glands produce too much oil. This excess sebum, combined with dead skin cells that haven't shed properly, creates a plug in the follicle. Bacteria that normally reside on the skin, known as Cutibacterium acnes, can thrive in this environment. The body’s immune system responds to this bacterial overgrowth, causing inflammation that leads to the redness, swelling, and discomfort associated with pimples. While the face is the most common site, acne can also affect the chest, back, and shoulders.

While a clogged pore is the immediate trigger for acne, a variety of factors contribute to this process. The development of acne is typically linked to one or more of the following core causes:

• Excess Oil (Sebum) Production: Glands that produce too much sebum make pores more likely to become clogged. This is often driven by hormonal changes, especially during puberty.
• Buildup of Dead Skin Cells: If your skin doesn't shed its dead cells efficiently, they can accumulate and bind with oil, forming a plug within the follicle.
• Bacteria: The proliferation of C. acnes bacteria inside a plugged follicle can activate an inflammatory response, leading to swollen, red blemishes.

In addition to these primary causes, several other factors can increase the risk of acne or trigger flare-ups:

• Hormonal Fluctuations: Androgens, hormones present in both men and women, are a major catalyst. Surges during puberty, menstrual cycles, pregnancy, or from conditions like polycystic ovary syndrome (PCOS), can stimulate oil production.
• Genetics: Acne often runs in families. If your parents or siblings had significant acne, you have a higher likelihood of developing it. Genetic predispositions can influence oil production, cell turnover, and inflammatory responses.
• Certain Medications: Some prescription drugs, including corticosteroids, can cause or worsen acne breakouts.
• Skincare and Cosmetics: Using heavy, oily products that are "comedogenic" (pore-clogging) can contribute to breakouts. Choosing products labeled "non-comedogenic" can help reduce this risk.
• Lifestyle and Environment: High levels of stress can affect hormone levels, which may worsen acne. Friction from items like helmets or tight straps can also cause a specific type of acne. While research is ongoing, some people find that high-glycemic diets or dairy products may influence their breakouts.

Acne can manifest as several different kinds of blemishes, and it's common to have more than one type at once.

• Whiteheads: These are clogged pores that are closed at the surface of the skin. They appear as small, flesh-colored or white bumps.
• Blackheads: These are clogged pores that remain open at the surface. The dark color is not dirt; it's the result of the trapped oil and skin cells oxidizing upon exposure to air.
• Papules: These are small, firm, pink or red bumps. They are inflamed follicles that can be tender to the touch but do not contain pus.
• Pustules: Often referred to as "pimples," these are inflamed bumps with a visible white or yellow center filled with pus.
• Nodules: These are large, solid, and often painful lumps that form deep within the skin. They are considered a more severe form of acne.
• Cysts: These are deep, painful, pus-filled lesions that can feel soft. Cystic acne is a severe form that has a high risk of leading to scarring.

Acne Severity Categories:

• Mild Acne: Primarily consists of whiteheads and blackheads with a few scattered papules or pustules.
• Moderate Acne: Involves more widespread breakouts, with a noticeable number of inflamed papules and pustules.
• Severe Acne: Is characterized by numerous inflamed blemishes, including painful nodules or cysts.

The primary symptom of acne is the appearance of the blemishes listed above on the face, particularly the forehead, nose, chin, cheeks, and jawline. Other related signs and symptoms can include:

• Skin that appears oily or shiny.
• Tenderness or pain, especially with deeper lesions like nodules and cysts.
• Dark spots or patches (post-inflammatory hyperpigmentation) that linger after a pimple heals. This is more common in individuals with darker skin tones.
• Permanent textural changes, such as indented pits or raised bumps, which are true acne scars and can result from more severe or untreated breakouts.

In addition to the physical symptoms, acne can have a significant emotional impact. Many people experience feelings of self-consciousness, anxiety, or low self-esteem because of their skin, and these feelings are a valid part of dealing with the condition.

While some mild cases of acne can be managed at home, it is a good idea to consult an esthetician for professional guidance in several situations. Consider making an appointment if:

• Your acne is severe, featuring deep, painful cysts or nodules.
• Your breakouts are resulting in scars or persistent dark spots.
• You have tried various over-the-counter products for several weeks without any noticeable improvement.
• The condition is causing you significant emotional distress, affecting your confidence or social life.
• You are an adult and have developed acne suddenly for the first time, as this could indicate an underlying medical condition.

A healthcare professional can provide an accurate diagnosis, help identify potential triggers, and discuss effective ways to manage the condition.
