Acne, a common skin problem, especially among teenagers and young adults, can be very bothersome to appearance and self-confidence. Understanding the various acne triggers is an important first step for effective prevention and treatment. This article will review some of the main acne triggers you need to watch out for.

One of the most frequent acne triggers is the overproduction of oil or sebum by the sebaceous glands in the skin. According to a report released by the British Association of Dermatologists on May 1, 2025, in London, increased androgen hormones during puberty are often the main cause of this excessive sebum production. Excess sebum can clog skin pores, creating an ideal environment for Propionibacterium acnes bacteria to thrive.

In addition, the buildup of dead skin cells also significantly contributes to the appearance of acne. Dead skin cells that do not shed properly can mix with sebum and clog hair follicles. A study published in the Journal of Investigative Dermatology in the April 2024 issue found that individuals with a tendency to develop acne have a slower rate of dead skin cell shedding compared to those without acne.

Another factor that is often an acne trigger is inflammation. When pores become clogged, P. acnes bacteria can multiply and trigger an inflammatory response in the skin. This inflammation is what causes the red, swollen, and painful bumps we often know as acne. Medical officers at the National Health Service (NHS) in the UK noted an increase in consultation cases related to skin inflammation due to acne during the summer of 2024, likely due to increased sweat and sebum production.

Although not directly causing acne, some external factors can also worsen the condition. The use of inappropriate skincare and cosmetic products or those containing comedogenic (pore-clogging) ingredients can be an acne trigger. Similarly, the habit of squeezing pimples can worsen inflammation and even leave scars. According to data from the “Dermacare London” beauty clinic collected on March 15, 2025, patients who have a habit of squeezing pimples tend to experience more severe inflammation and longer healing times.

Managing these acne triggers through a proper skincare routine, choosing non-comedogenic products, and avoiding the habit of squeezing pimples are important steps to maintain facial skin health and prevent acne breakouts. If acne problems persist, consulting a dermatologist is a wise step to get more specific treatment.

Potamogeton pectinatus, commonly known as sago pondweed or fennel pondweed, is a globally distributed submerged aquatic plant playing a vital role in freshwater and brackish ecosystems. Unlike some of its relatives, sago pondweed is often considered a beneficial species, particularly for wildlife.  

Identifying Sago Pondweed:

This perennial plant features slender, branching stems that arise from creeping rhizomes. Its leaves are long and very narrow, almost thread-like, typically ranging from 2 to 5 centimeters in length and less than 2 millimeters wide. These leaves are arranged alternately along the stem. Potamogeton pectinatus produces small, inconspicuous flowers on spikes that may emerge above the water surface. A key characteristic is the formation of nutritious tubers on its rhizomes.  

Ecological Significance: A Wildlife Powerhouse:

Sago pondweed is highly valued for its ecological contributions:

• Crucial Food Source for Waterfowl: Its tubers and seeds are a primary food source for numerous waterfowl species, including diving ducks, swans, and geese, especially during migration and staging periods.
• Habitat and Cover: The dense underwater foliage provides important habitat and cover for various fish, amphibians, reptiles, and invertebrates.
• Oxygen Production: Like other submerged aquatic plants, sago pondweed contributes to oxygenation of the water through photosynthesis.  
• Nutrient Cycling: It can absorb excess nutrients from the water column, potentially helping to improve water quality and suppress algal blooms.  
• Sediment Stabilization: The rhizomes and roots help stabilize bottom sediments.  

Sago Pondweed in Aquariums (With Caution):

While beneficial in natural ecosystems, sago pondweed can also be grown in aquariums. Its fine leaves offer a unique aesthetic, and it can contribute to oxygenation. However, its rapid growth potential means it can quickly overtake a tank if not managed properly. Regular trimming is essential.  

Potential for Overgrowth (Localized):

In some specific situations, particularly in nutrient-rich waters or managed systems like irrigation canals, sago pondweed can exhibit rapid growth and become a nuisance by impeding water flow. However, this is less common than with more aggressively invasive species
