What Causes Cystic Acne? Comprehensive Insights

Understanding the Basics of Cystic Acne

Cystic acne stands out as the most intense type of acne, marked by large, deep, painful cysts buried beneath the skin's surface. 

Unlike other acne forms, cystic variations stem from a combination of bacteria, oil, and dry skin cells that trap within the hair follicle, leading to inflammation. This deep-rooted inflammation can result in long-lasting and often scarring blemishes.


The Primary Causes of Cystic Acne

Cystic acne, a severe form of acne, develops when cysts form deep beneath the skin due to a combination of causes:
  • Bacterial Growth: The skin is home to various bacteria, including Propionibacterium acnes. While typically harmless, in certain conditions, they can multiply, leading to an inflamed blemish. The depth and severity of the inflammation dictate whether a blemish evolves into a cystic lesion.
  • Excess Oil Production: Sebaceous glands produce oil (sebum) to keep our skin hydrated. However, factors like hormonal imbalances can stimulate these glands to produce excessive amounts, creating an ideal environment for acne to thrive.
  • Dead Skin Cell Accumulation: Regular shedding of skin cells is natural. But, sometimes, they don't shed completely and can clog pores. This blockage can cause oil to accumulate beneath the skin, providing fertile ground for cystic acne formation.
  • Hormonal Fluctuations: As mentioned earlier, hormonal changes, especially elevated levels of androgens, can contribute to excess oil production, which is a significant factor in cystic acne formation.


Hormonal Imbalances and Cystic Acne

Hormones, particularly androgens, play a pivotal role in the formation of cystic acne. Elevated levels of these hormones, which rise during events like puberty, pregnancy, and specific menstrual phases, amplify the skin's oil production. 

Overproduction of this oil provides a fertile environment for acne-causing bacteria. Moreover, conditions like Polycystic Ovary Syndrome (PCOS) can exacerbate hormonal imbalances, further increasing the risk of cystic acne.


Lifestyle Factors Contributing to Cystic Acne

While internal factors like hormones and genetics play a role in cystic acne development, external, or lifestyle, factors can exacerbate or even instigate flare-ups:
  1. Diet: Studies have indicated a potential link between certain foods and acne. Foods with a high glycemic index, dairy products, and diets rich in refined sugars have been associated with an increased risk of developing acne.
  2. Stress: Chronic stress can lead to hormonal imbalances, which can subsequently impact oil production and inflammation—two primary components of cystic acne.
  3. Poor Skincare Routine: Not cleaning the skin thoroughly can result in the accumulation of oil, dirt, and dead skin cells. Additionally, over-exfoliating or using harsh products can irritate the skin and disrupt its barrier, making it more susceptible to acne.
  4. Medication Side Effects: Some medications, including specific steroids, hormonal treatments, or even certain birth control pills, can lead to the development or exacerbation of cystic acne.
  5. Environmental Factors: Excessive humidity or pollution can clog pores and intensify skin oiliness. On the other hand, extremely dry conditions can cause the skin to overproduce oil as a compensatory mechanism, again contributing to acne development.
  6. Cosmetics: Oil-based or comedogenic makeup can block pores, leading to outbreaks. It's crucial to choose non-comedogenic and hypoallergenic products if one is prone to acne.

Which sunscreen should I use, Inorganic or Organic?

Overview There are mainly two types of sunscreen: Physical and Chemical.  Inorganic sunscreens are also called Physical Sunscreen or Mineral Sunscreen. Organic sunscreens are also called Chemical Sunscreens. A term Inorganic and organic are derived from chemistry. * Organic Chemistry: The Study of Molecules Based on Carbon, Hydrogen, and Nitrogen * Inorganic Chemistry: The study of compounds other than organic chemicals A sunscreen can, of course, have both of these functions. It is called a Mixed sunscreen or a Combined sunscreen, and these days, many brands are developing products like this. Through this post, let's find out what inorganic and organic sunscreens are, and what sunscreens are most suitable for one to use. The difference between inorganic and organic sunscreen. Inorganic sunscreen is a sunscreen that forms a protective layer on the surface of the skin to block ultraviolet rays before they penetrate into the skin. Most product contains titanium dioxide and zinc oxid...

Misleading Claims in Microneedle Skincare Products: 82 Cases Identified

     Recently, microneedle skincare products have gained significant popularity, but Korea’s Ministry of Food and Drug Safety (MFDS) has uncovered that over 80% of these products being sold online are making false or exaggerated claims. After reviewing 100 online posts, the MFDS found that 82 of them violated Korea’s cosmetics regulations, leading to requests for the posts to be blocked by the Korea Communications Standards Commission. The misleading advertisements primarily claimed that microneedles could penetrate deep into the skin layers or promised immediate pore reduction, both of which are not scientifically validated for general cosmetic products. Microneedles are a medical technology designed to deliver substances into the deeper layers of the skin, typically used in drugs and medical devices. However, in the cosmetics industry, these products generally do not have the same capabilities. Some companies falsely advertised their products as having effects similar t...

Korean Beauty Trends & Industry News: 24-05-08

Cosmax Leads in Cosmetics with New Hair Loss Evaluation Technology      Cosmax, a South Korean cosmetics company, has announced the development of a novel hair loss evaluation method using "hair and follicle mimicking organoids." This technology was showcased at the 2024 Organoid Developer Conference in Seongnam, Gyeonggi Province last month.  Organoids, made from stem cells, excellently replicate human cellular structure and function. In collaboration with OrganoidScience, Cosmax has successfully recreated androgenetic hair loss symptoms by introducing growth factors into reprogrammed stem cells to create a scalp mimic.  Furthermore, their proprietary ingredient "Soyact" has been validated for its effectiveness in suppressing male pattern baldness and received non-prescription functional certification from the Korean Ministry of Food and Drug Safety. Cosmax sees this technology not only advancing hair loss treatment materials but also setting a new standard in ...
