Acne begins inside the tiny openings in the skin from which hair grows. Under hormonal influence the oil glands attached to these openings produce more oil, dead skin cells fail to shed properly and block the opening, and bacteria that normally live on the skin multiply in this blocked, oily space. The body reacts with inflammation, and the result is the range of spots people call pimples: blackheads and whiteheads, small red tender bumps, pus-filled spots, and in more severe cases deep painful lumps that sit under the skin for weeks. Acne is not a hygiene problem and it is not caused by a single food. It affects the face most often, but the chest, upper back and shoulders are also common sites.
Acne is extremely common in the teenage years, but it is not only a teenage problem. Many adults, particularly women in their twenties and thirties, get spots along the jawline and chin that flare before their periods. What makes acne worth treating properly rather than waiting out is what it leaves behind. Deep and repeatedly inflamed spots can leave pitted scars that are far harder to treat than the acne itself, and even mild spots often leave dark marks that take months to fade on Indian skin. People frequently delay because they are told it will settle on its own with age. In the meantime many turn to fairness creams, so-called instant glow creams and steroid creams bought without a prescription or recommended by a friend or a shop. These may clear the skin briefly and then cause a rebound of severe acne, redness, burning and visible blood vessels that takes a long time to repair. Acne responds well to properly chosen medical treatment, and the earlier that starts, the less there is to repair later.
Signs & Symptoms
- Blackheads and whiteheads appear on the nose, forehead and chin, on skin that turns oily and shiny within a few hours of washing.
- Small red, tender bumps come up on the face, and some develop a white or yellow head.
- Deep, painful lumps form under the skin and last for weeks before settling.
- Dark brown marks remain for months where the pimples have healed.
- Pitted or raised scars are forming, most often on the cheeks, temples and jawline.
- Spots flare in the week before periods, often along the jawline and chin.
- Similar spots appear on the upper back, chest or shoulders.
- The face burns, turns red or breaks out badly after using or after stopping a fairness or steroid cream.
Causes & Triggers
- Increased oil production driven by normal hormonal activity at puberty and in adult life.
- Blockage of the pore by dead skin cells that do not shed properly.
- Multiplication of Cutibacterium acnes bacteria in the blocked pore, followed by inflammation.
- Hormonal conditions such as polycystic ovarian syndrome, suggested by irregular periods, unwanted facial hair or hair thinning along with acne.
- A family history of acne, which affects both how early it starts and how severe it becomes.
- Pore-blocking cosmetics, heavy hair oils reaching the forehead, sweat, friction from helmet straps and masks, and hot humid weather.
- Steroid creams, unregulated fairness or glow creams, and certain medicines and supplements, including some protein and bodybuilding preparations.
Diagnosis & Treatment
Treatment starts with assessing what kind of acne you have and what has been done to it already. The doctor will look at the types of spots present, how deep and inflamed they are, how much of the face and body is involved, whether marks or scars have started forming, and what your skin type is. Just as important is the history: how long it has been going on, which creams, tablets, home remedies, salon treatments and cosmetics you have used, whether any steroid or fairness cream has been applied to the face, what medicines or supplements you take, and for women, whether periods are regular. Blood tests and hormonal tests are not needed for most patients but may be advised for selected women with irregular cycles, excess facial hair or sudden severe acne, and monitoring tests are required before and during certain oral treatments.
Treatment is then chosen to match the severity. Mild acne is usually managed with topical therapy applied to the whole affected area rather than dabbed on individual spots, using medicines that unblock pores, reduce bacteria and calm inflammation. Moderate to severe acne generally needs oral medication as well, which may mean a limited course of antibiotics, hormonal treatment in selected women, or, for severe, nodular or scarring acne, a course of the strong oral retinoid isotretinoin, which is highly effective but must be taken under supervision with counselling, monitoring and strict avoidance of pregnancy during and after the course. In-clinic procedures are used in some cases where indicated, and their suitability is decided after examination. Realistic timelines help enormously. Acne treatment does not work overnight, because it works on the spots that are still forming beneath the surface. Early improvement is usually seen at about six to eight weeks, and good control commonly takes three to six months. Once the skin is clear, maintenance treatment is usually continued for a period to stop new spots forming. Dark marks fade slowly over months with sun protection and treatment, and true pitted scars are addressed only after the active acne is properly controlled.
What you do at home decides much of the outcome. Expect some dryness, mild peeling or a brief worsening in the first few weeks with some treatments, and use a simple non-comedogenic moisturiser and daily sunscreen alongside, since sun exposure darkens marks and some acne medicines make the skin more sun sensitive. The most common mistakes are changing products every two or three weeks, using several strong products together, scrubbing the face, washing it many times a day, and squeezing spots, all of which increase inflammation and scarring. Avoid fairness creams, steroid creams and any unlabelled cream recommended by a shop, a salon or a relative, and tell your doctor honestly if you have used one, because that changes the treatment plan. Stopping treatment the moment the face clears is the single most frequent reason acne comes back. Follow the plan for the full duration, keep review appointments, and raise side effects with the doctor rather than quietly stopping.
When to See a Doctor
- You have deep, painful lumps or cysts, or pitted scars and long-lasting dark marks are already forming.
- There is no clear improvement after six to eight weeks of over-the-counter products used properly.
- You have used a fairness cream, steroid cream or unlabelled cream and your skin now burns, stays red, or breaks out badly when you stop it.
- Acne comes with irregular periods, unwanted facial hair or hair thinning, or has appeared suddenly and severely in adult life.
- The acne is affecting your confidence, sleep, studies, work or willingness to meet people.
Common Questions
Will pimples go away on their own as I get older?
Acne often does improve with age, but that can take years, and many people continue to get spots into their twenties and thirties. The problem with waiting is that deep or repeatedly inflamed spots can leave pitted scars, which are much harder and more expensive to treat than the acne itself. Treating early is mainly about preventing permanent marks and scars.
Do oily food, chocolate and sweets cause pimples?
Eating a samosa or a bar of chocolate does not directly cause a pimple, and greasy food on the plate is not the same as oil in the skin. There is reasonable evidence that a diet very high in sugar and refined carbohydrates, and in some people large amounts of skimmed milk or certain protein supplements, can worsen acne, so a balanced diet helps, but diet is a minor factor compared with hormones, oil production and pore blockage. Acne is also not a sign of poor washing, and scrubbing or washing many times a day usually makes it worse.
Will the marks and scars go away?
Flat brown or dark marks left after a pimple usually fade on their own over several months, and this is faster with sun protection and appropriate treatment. Pitted or depressed scars are permanent changes in the skin structure and do not disappear on their own, though their appearance can often be improved with treatment planned after the active acne is controlled. The best way to deal with scars is to prevent them by treating acne early and not squeezing spots.
Is isotretinoin dangerous? I have heard frightening things about it.
Isotretinoin is a strong and very effective medicine for severe, nodular or scarring acne, and it has been used for decades. It does have real side effects, most commonly dry lips, dry skin and dry eyes, it requires blood tests before and during the course, and it must never be taken during pregnancy or without reliable contraception in women who could become pregnant. It should only be taken on a doctor's prescription with proper counselling and follow-up, and never bought over the counter or copied from someone else's prescription.
What will treatment cost and how many visits will I need?
A clinic consultation in Vidyadhar Nagar is Rs 300 and an online consultation is Rs 500, with medicines and any tests charged separately. Acne is usually reviewed after about four to six weeks initially so the plan can be adjusted, and then less often once the skin is settling. Consultations are available in Hindi and English.
