Have you ever noticed that pimples seem to pop up at the worst possible times, like before a big event or an important day? Let’s explore why pimples happen and what we can do about them.
Your skin is covered with tiny openings called pores, which are actually hair follicles. Inside each follicle is a gland that produces an oily substance known as sebum. Sebum is important because it keeps your skin and hair moisturized. However, sometimes these follicles get clogged with dead skin cells and oils, creating a blockage. When this happens, sebum gets trapped inside, causing the follicle to swell.
Bacteria love to feed on the trapped sebum and dead skin, which can lead to an infection. Your body’s immune system responds by sending blood to the area, causing redness and swelling. White blood cells also rush in to fight the infection. When these cells die, they mix with dead skin and sebum, forming a pus-filled pimple.
If the blockage is under the skin, it forms a white bump called a whitehead. If it’s above the skin and turns black, it’s known as a blackhead. The black color isn’t dirt; it’s caused by melanin in the dead skin cells reacting with oxygen.
Pimples are most common during the teenage years because of increased androgen hormones like testosterone, which boost sebum production. However, pimples can appear at any age, often triggered by stress. The stress hormone cortisol can increase inflammation and suppress the immune system, making it harder to fight acne-causing bacteria.
For typical breakouts, washing your face to remove excess oil and exfoliating to clear dead skin can help prevent clogged pores. However, acne is often influenced by genetics and hormones, so these methods might not be enough.
There are various treatments available. Benzoyl peroxide targets acne-causing bacteria, salicylic acid helps clear blockages, and retinoids reduce sebum production. Some treatments might have side effects, especially for women. Oral contraceptives can sometimes help by reducing androgen hormone levels.
It’s always a good idea to consult a doctor to find the best treatment for you. Exciting new research is exploring how altering the skin’s bacteria might help cure pimples. Scientists have found that people who don’t get acne have a different strain of bacteria on their skin, which could lead to new therapies.
We also want to highlight the annual letter from the Bill and Melinda Gates Foundation, which discusses global issues. This year’s question is: What would your superpower for good be?

Using clay or playdough, create a 3D model of the skin, including pores, hair follicles, and sebaceous glands. This will help you visualize how pimples form. Present your model to the class and explain the process of pimple formation.
Conduct an experiment to test the effectiveness of different facial cleansers or treatments. Document your process and results over a week, and present your findings on which method was most effective in preventing pimples.
In groups, create a short skit that demonstrates how hormones and stress contribute to pimple formation. Use props and costumes to make it engaging, and perform it for your classmates to enhance understanding of these concepts.
Research the pros and cons of different acne treatments, such as benzoyl peroxide, salicylic acid, and retinoids. Hold a class debate on which treatment is most effective, considering side effects and long-term benefits.
Read about the latest research on acne treatment, such as altering skin bacteria. Write a short essay or create a presentation on how these new therapies could change the future of acne treatment and share your thoughts with the class.

Whether it’s the first day of school, a big interview, or your wedding day, pimples often appear at the most inconvenient times. But why do they occur, and how can we get rid of them?
The term “pore” refers to hair follicles, and your body is covered in them. Within each follicle is a gland that produces an oily substance called sebum, which helps keep your hair and skin moisturized. However, if a hair follicle becomes clogged with dead skin cells and oils, a blockage is created. As sebum continues to be produced, it becomes trapped within the follicle, causing it to enlarge. This is where bacteria come into play, feeding on the dead skin and sebum, which can lead to infection.
Your immune system responds by sending blood to the area, resulting in redness and inflammation. White blood cells also arrive to help clear the infection. When these white blood cells die, they combine with dead skin and sebum, forming a pus-filled pimple. If the blockage occurs under the skin, it creates a white bump known as a whitehead. If the blockage is above the skin and black discoloration occurs, it’s known as a blackhead. This discoloration is due to melanin in the dead skin cells reacting with oxygen, creating a black color; it is not dirt.
Most pimples occur during the teenage years due to increased levels of androgen hormones, such as testosterone, in the body. At the onset of puberty, testosterone boosts sebum production, leading to more blockages. However, breakouts can happen at any age, often triggered by stressful events. The stress hormone cortisol increases inflammation in the body, resulting in more red bumps on the face and can also suppress the immune system, making it harder for the body to fight the bacteria causing acne.
So, how can we combat pimples? For normal breakouts, cleaning your face to remove excess oil can help prevent pore blockage, and occasional exfoliation can remove dead skin. However, acne often cannot be resolved solely through these methods. It’s important to remember that cleanliness and diet do not play a major role in acne; rather, genetics and hormones are significant factors.
There are various treatments available, such as benzoyl peroxide, which targets acne-causing bacteria, salicylic acid, which helps remove dead skin blockages, and retinoids, which reduce sebum production. Some treatments may have side effects, particularly for women. Oral contraceptives have shown some success in decreasing androgen hormone production, thereby reducing sebum.
Consulting with a doctor to determine the best treatment regimen for you is always advisable. Exciting new therapies and cures may be on the horizon, thanks to scientific research. By studying individuals who do not experience acne, scientists have discovered that while the bacteria that typically causes acne still exists on their skin, it is a different strain. This suggests that future therapies may involve a closer examination of the bacterial levels on the skin and whether altering the skin’s microbiota could help cure pimples.
We are also pleased to support the annual letter from the Bill and Melinda Gates Foundation, which addresses global issues. This year’s question is: What would your superpower for good be? It could be more clean energy or more time, each having different implications for wealthy countries and the world’s poorest families.
