Is It Common to Develop More Pimples After Starting La Roche-Posay Gel?
Hello everyone! I’m a 27-year-old woman who struggled with significant facial acne until about a year ago. My situation improved dramatically, about 90%, due to medication I took for pneumonia. However, I’ve recently noticed that I'm occasionally breaking out in new blemishes and experiencing some histamine bumps on my body, which typically vanish within a day. For the past three days, I’ve introduced La Roche-Posay gel into my skincare routine targeting my facial acne. Initially, I applied it incorrectly by directly rubbing the gel onto my skin, followed by rinsing it off. This method caused a slight burning sensation. However, after switching to the proper application technique—mixing the gel with water to create a foam before applying—it seems there’s no burning, and while my acne has shown some improvement, I've also noticed new pimples surfacing in areas that were previously clear, particularly on my cheeks that had only minor redness before. I came across the term ‘purging phase’ online, which suggests that this could be normal when starting with a new acne treatment, as it indicates the product is effectively cleansing the skin. I wanted to check with all of you before reaching out to my dermatologist to determine if this is a cause for concern. Additionally, I've been experiencing some itchiness on my face and body, and this facial itchiness appears to be new, which does make me anxious. I tend to be a bit of a hypochondriac, but I’m striving to be objective about the product's effects to accurately determine if these sensations are legitimate side effects or simply manifestations of my anxiety. I’m not certain if I have any allergies to the ingredients. Has anyone else encountered this purging phase or experienced itchiness after starting La Roche-Posay gel? This is my first endeavor into acne products, so I appreciate your patience as I navigate through this learning process. Thanks for taking the time to read my post, and I apologize if my grammar isn't perfect; English isn't my native language.

It's understandable to feel concerned when introducing a new skincare product, especially when it comes to acne treatments. The experience of noticing new blemishes after starting La Roche-Posay gel could be a common reaction as your skin adjusts, but it's important to monitor your symptoms closely.
Explanation
When starting a new acne treatment, some individuals may experience a "purging phase." This phase can occur because the product might accelerate the skin's cell turnover, bringing underlying impurities to the surface before they clear. However, not all new breakouts are due to purging; they could also result from irritation or an allergic reaction to the product's ingredients.
It's also worth noting that the itchiness you're experiencing could indicate a reaction to the gel. Given your description of the burning sensation you felt initially, it’s good to be cautious and observant, especially if you're prone to anxiety about your health.
Next Steps
-
Monitor Symptoms: Keep a diary of your skin’s response:
- Document when new blemishes appear, any changes in the itching, and how often it occurs.
- Note any other products coming into contact with your skin.
-
Continue Proper Application: Stick with the correct application method you’ve found comfortable (mixing with water) to minimize irritation.
-
Reduce Irritants: Avoid using other potential irritants during this period (e.g., exfoliating scrubs or products containing alcohol).
-
Patch Test: If you haven't already, consider patch testing the gel on a small area of skin for a couple of days to check for any allergic reactions.
-
Consult a Dermatologist: If the itchiness persists or worsens, or if new breakouts become concerning, it's wise to reach out to your dermatologist. They can provide professional insight and adjust your skincare regimen as needed.
Remember, it's normal to feel anxious during this adjustment phase, but maintaining a clear perspective through observation can help you differentiate between typical reactions and potential cause for concern. Take care, and don't hesitate to seek professional advice as you navigate this new treatment.

Could I be experiencing a Hiatal Hernia? Breathing difficulties and abdominal pain consuming my life.
F20, 5'8", 150 lbs. For nearly two years, my life has been plagued by a constant sense of distress and discomfort. The situation has become so unbearable that I feel lost and unsure of what to do next. To explain my situation, I should mention that my anxiety is so severe it prevents me from seeking medical help—at times, my heart races to 180 beats per minute, accompanied by nausea, trembling, tingling sensations, faintness, and significant chest pain. This intense anxiety has kept me confined to my home for the past three years. I am at a loss about what is happening with my stomach and abdomen, but the sensations are dreadful and unlike anything I've encountered before. It feels as if an invisible barrier is present in my upper abdomen, either constricting or obstructing it in some way. Describing this sensation is challenging; when I sit quietly, it can feel as though something is compressing my abdomen. The most concerning symptom I face is the difficulty in breathing. My breathing has become a conscious effort—I have to actively think about each breath rather than it occurring naturally. Exhaling poses the greatest challenge for me; I often feel unable to release my breath completely. Inhaling is somewhat of a struggle too, but it pales in comparison to the difficulty I experience while trying to exhale. I find myself unable to laugh, cry, or engage in activities that require full exhalation. After just a few seconds of trying to exhale completely, it feels as if my abdomen is excessively contracting, causing significant discomfort. These breathing difficulties have become a relentless companion for the past eighteen months, persisting around the clock. I feel utterly trapped and am desperate for relief. The ongoing abnormality of my breathing prevents me from finding peace, as my upper abdomen remains consistently painful. This sudden onset of distress has left me in a state of confusion and deep troubling anxiety, where I struggle to manage my heart rate, especially in moments of panic; my breath barely supports me while sitting still, let alone during an anxiety attack. Despite my efforts to diagnose this unsettling condition, I am thoroughly perplexed and uncertain about what it could be. There’s a possibility that I might be dealing with a hiatal hernia, yet the absence of additional symptoms makes it difficult to draw a conclusion. Every day, I grapple with this relentless turmoil, worrying that something serious could be at play, especially since this has been ongoing for almost two years. I don’t feel like my true self anymore; instead, it feels as if I am caught in a nightmare I can’t escape.
Experiencing Dizziness on the Toilet?
Age: 33 Male Apologies for the graphic details, but I just went through a troubling experience and I'm currently trying to recover. As someone who has epilepsy, I am anxious about triggering a seizure. This isn't the first time I've encountered this, and it's genuinely alarming. When I head to the restroom for a number two, I'm not one to rush through it. I often deal with digestive issues, notably IBS, which I believe might be linked to my medication. Initially, everything seemed normal as I had smaller, solid bowel movements, but then the discomfort in my lower abdomen began. I noticed that I was also passing gas intermittently. There comes a point when I need to pause between each push; otherwise, I risk overexerting myself. However, it feels like there’s still more to come, and the pain is quite intense. Suddenly, I started to feel light-headed, which signaled to me that something was off. Before long, I found myself nearly toppling off the toilet, grappling with severe dizziness and weakness. I even felt nauseous, along with numbness and tingling in my hands. Despite still attempting to relieve myself, the consistency changed; although it wasn't completely liquid, it was far from solid. Eventually, I had to abandon the toilet and lie down on the bathroom floor because I couldn't hold myself up anymore. When the urge returned, I managed to get back on the toilet, but once everything was finally expelled, the pain subsided, and I began to feel a bit better. This occurred about thirty minutes ago, yet I'm still not feeling quite myself. I'm curious about why this happens. I have experienced some constipation in the past few days, but I didn’t expect it to escalate to this extent. What I ultimately expelled was an unusually large amount, more than I’ve ever seen. I'm reaching out to see if anyone has insights into why these episodes occur. It's been a distressing experience, and I would appreciate any thoughts on the matter. Thank you.
Exploring the Causes of My Gastrointestinal Issues: Seeking Guidance
For the past half-year, I have been enduring chronic constipation that has led to a small fissure and hemorrhoids, along with persistent abdominal bloating. Regardless of what I consume, I experience significant distension, leaving me looking as if I am pregnant. This bloating occurs immediately after eating, and even when I don’t eat, I still feel some level of discomfort, albeit less intense. Despite attempting a gluten-free and dairy-free diet, I noticed little improvement. My symptoms also include frequent burping, an overwhelming sense of fullness after minimal meals, and a general fatigue that clouds my daily life. Additionally, I am experiencing mood fluctuations, increased hair shedding, shallow breathing, and very noticeable dark circles under my eyes. I have a constant itch in my throat, dust allergies, and my dermatitis has flared up recently, though it remains manageable. Six months ago, I also dealt with Eustachian Tube Dysfunction (ETD). In terms of blood work, my ferritin level is at 18, vitamin B12 is 178, hemoglobin (HB) is 13.5, and vitamin D is measured at 35. My typical diet consists of two varieties of vegetables, two types of fruits, nuts, dates, egg whites, chicken or fish, and either rice or wheat. Despite this seemingly balanced intake, my nutrient levels remain low. I'm left pondering whether I could have methane-dominant SIBO. After consulting with two separate gastroenterologists, SIBO was never mentioned as a possibility. Being from India, I also question whether local healthcare facilities test for this condition. I often wonder if I am simply overthinking my health issues and experiencing heightened anxiety. The results from an endoscopy indicated antral gastritis, and the colonoscopy showed terminal ileitis; the biopsy confirmed chronic ileitis. Unfortunately, nothing has alleviated the bloating, and the only effective combination for regular bowel movements has been a laxative, Lactifibre, and Purease. The treatment plan from my gastroenterologist included three months of proton pump inhibitors (PPIs), Purease, two weeks of digestive enzymes, one week of Rifagut, probiotics, Lactifibre, and a laxative. My doctor stated that my symptoms are attributed to mild inflammation, suggesting that I should incorporate more vegetables into my diet after the third month of treatment. Ironically, even though I love vegetables and consumed them abundantly before my bloating began, they often exacerbate my symptoms. While I experienced hope on the first two days of Rifagut, from day three onward, the bloating returned. The only inquiry from my gastroenterologist was regarding my anxiety levels. My job isn’t particularly stressful, and outside of these gastrointestinal issues, I don’t currently face major anxieties. I had a period of depression between 2020 and 2022, but I’ve returned to my usual self, despite occasional mood swings. I sought a second opinion from another gastroenterologist, who concluded that nothing seemed wrong, and they were unsure about the source of the inflammation, suggesting it could be tied to psychological factors. They recommended exercise, weight loss, and a diet rich in probiotics—changes I have rigorously adhered to for the past four months, yet my symptoms persist unabated. In general, I maintain a healthy lifestyle, consuming whole foods and avoiding junk food, while hydrating with 2-3 liters of water and engaging in strength training and cardio sessions four to five times a week. As a bit of background, I have polycystic ovary syndrome (PCOS), which predisposes me to quick weight gain if I cease working out. I consistently exercised for two years, shedding 22 pounds, but upon taking a break, I regained all that weight within six months. Recently, I have resumed a regular gym routine for the last four months. I apologize for the lengthy account; I was uncertain about what details to leave out. Thank you in advance for any insights you may have.
Concerns for Friend Facing Mysterious Gastrointestinal Issues
A close friend of mine, a 28-year-old woman, has been enduring intense gastrointestinal problems for the last week. This is unprecedented for her, and the symptoms are so severe that she has had to visit the emergency room several times this week. It all began last Saturday when she spent time with a friend, shopping and grabbing some food before heading home. During her journey back, she began to experience significant itching that lasted throughout the night. This discomfort was further exacerbated by twitching in her legs, and the only relief she could find came from taking numerous showers. The following morning, she sought medical attention at the ER, where the staff recommended taking Benadryl, which did successfully alleviate the itching. However, the next day, she developed intense pain in her chest and back. Another emergency room visit yielded normal test results, with the sole abnormality noted during her cardiac ultrasound being excessive gas accumulation. After receiving a GI cocktail containing lidocaine, her gastrointestinal symptoms improved enough for her to finally get some rest and leave the hospital. Although the doctors prescribed Pepcid, it failed to provide relief. On Tuesday night, she returned to the ER due to a resurgence of severe gas pain in her chest and back. They administered morphine to manage her pain and advised her to follow a liquid diet for several days. Despite her efforts, her symptoms persisted, compelling her to go back to the emergency room on Wednesday night. She was admitted and remained under observation until Friday morning. Again, her tests returned normal results, and even after an endoscopy and colonoscopy, no issues were identified. As if this were not enough, she was readmitted on Saturday night due to widespread pain and a headache and remains hospitalized as of this Sunday morning. To date, the emergency room staff have been unable to diagnose her condition, and my worry continues to grow. She does not consume alcohol or smoke and generally maintains an active and healthy lifestyle. Has anyone else encountered something like this? Is there any reason for optimism regarding her recovery? My concern for her is immense, and all I'm seeking is reassurance about her condition and possible treatments for what she is going through.
Health Concerns Following Viral Illness
I am a 33-year-old assigned female at birth, currently on a daily regimen of 2mg estradiol and 100mg spironolactone, with a childhood diagnosis of HSV-1. Recently, I've been experiencing persistent dull pain in the upper central region of my abdomen, along with joint pain, fatigue, and intermittent facial flushing following a recent illness that I suspect could have been COVID-19. During what I refer to as the "COVID phase," which lasted approximately a week beginning in early to mid-May, I encountered a range of symptoms. These included joint and muscle discomfort, overwhelming fatigue, episodes of a hot face that would appear and fade throughout the day, outbreaks of cold sores, and a fever that persisted during that period. Post-illness, the flushing on my face has continued, and along with it, the dull ache in my upper abdomen persists in the epigastric area. For the past few weeks, I’ve had this slight aching sensation in the upper midsection of my stomach. It’s not a sharp pain but rather a lingering dull discomfort. I’ve noticed that it doesn’t correlate with my meals or specific foods, and I haven't pinpointed any factors that seem to exacerbate or alleviate it. My partner and I fell ill a few weeks back with what seemed like a viral infection (possibly COVID or one of its variants). I initially felt considerable fatigue and a general sense of discomfort. During this illness, I also experienced the recurring hot face phenomenon but haven’t experienced any fever since. Interestingly, while consuming alcoholic beverages one day, I noticed my facial flushing intensified after drinking. Considering these symptoms, I am curious whether the abdominal discomfort could be associated with my recent viral infection or the stress it induced. Could it possibly signal indigestion, gastritis, or acid reflux? Or might it be indicating something deeper related to my digestive health? Could it even be linked to long COVID?
