We observed five notable cases of acneiform eruptions linked to vitamin B12 in women aged 21 to 62. These eruptions manifested between one week and five months after starting vitamin B12 therapy.
The primary symptoms consisted of papules and pustules appearing mainly on the face. In three of the patients, these skin issues also extended to areas like the neck, shoulders, chest, and upper back, but interestingly, there were no signs of comedones or cysts.
Out of the five women, two had particularly high levels of vitamin B12 in their blood. A closer look at one patient's skin under a microscope revealed eosinophilic folliculitis, a type of inflammation in hair follicles. Fortunately, all patients experienced spontaneous and complete recovery within three to six weeks after stopping vitamin B12 treatment.
Overall, while vitamin B12 did not provide a benefit for acne treatment, it highlighted an unusual side effect of acne-like symptoms in these cases.
We observed a fascinating case involving a 47-year-old man who developed a skin condition after starting vitamin B12 treatment for pernicious anemia. Just six weeks into his weekly injections of hydroxocobalamin, he experienced a sudden and widespread outbreak of inflammatory acne-like bumps on his face and trunk. This skin eruption was not only extensive but also caused significant itching and included comedones, commonly known as blackheads, particularly on his chest.
Upon closer examination, the medical team diagnosed him with a vitamin B12-induced acneiform eruption, which is different from typical acne vulgaris. This distinction came from several unique factors, including the patient's age, the sudden onset of the condition, and the presence of pruritus (itching) alongside a uniform type of lesions across non-seborrheic areas.
After normalizing his vitamin B12 levels, the hydroxocobalamin injections were stopped, and lymecycline—a type of antibiotic—was introduced. Remarkably, this led to a complete resolution of his skin lesions within three months. This case highlights how vitamin B12 can have an unusual, but significant impact on skin health, demonstrating that its effects are not just limited to its role in blood health but can extend into dermatological issues as well.

Vitamin B12 affects acne mechanisms
Vitamin B12 modulates the transcriptome of the skin microbiota in acne pathogenesis.
We explored how vitamin B12 influences the skin microbiota and its potential connection to acne development. By analyzing the skin microbiota of acne patients and healthy individuals, we found that there are significant differences in the transcriptional profiles of these groups. Specifically, we noticed that the pathway responsible for vitamin B12 biosynthesis in a skin bacterium called Propionibacterium acnes was less active in those with acne.
To dive deeper, we conducted an experiment with healthy subjects who were given vitamin B12 supplements. Our findings showed that this supplementation suppressed the expression of vitamin B12 production genes in P. acnes and altered the overall activity of the skin microbiota. Interestingly, one participant developed acne just a week after starting the supplements, shedding light on a possible mechanism behind the observed connections.
Additionally, we identified that vitamin B12 supplemented P. acnes cultures led to an increased production of porphyrins, compounds known to trigger inflammation associated with acne. This suggests a novel pathway through which vitamin B12 may influence acne development, aligning with clinical observations that some individuals experience breakouts following vitamin B12 supplementation.
Overall, our study emphasizes the complex interplay between vitamin B12 and the skin microbiota, hinting at its pivotal role in acne pathogenesis.

Acne breakout resolved
By process of elimination, I realised that the itchy skin and resulting acne on my face and neck were due to a deficiency of B12. After discontinuing those vitamins and adding pantothenic acid, my acne stopped appearing within a day, and existing ones faded over the week. I've learned that the absorption might lead to an overdose risk, especially after switching from metformin to berberine.

The combination of B12 and Foliating didn't work for me. After taking it, I experienced a breakout of acne, and I never noticed any increase in energy. I had adverse effects for two days, which was disappointing. I suggest taking folic acid separately if you're considering this, as I ended up dividing the tablets to reduce the dosage. Now, the whole family takes them.

Tracnil™ improves acne in PCOS
Efficacy and Safety of Tracnil™ Administration in Patients with Dermatological Manifestations of PCOS: An Open-Label Single-Arm Study.
We evaluated the effectiveness of Tracnil™, a treatment combining myo-inositol, folic acid, and vitamin D3, specifically addressing acne in women with normal hormone levels who exhibit signs of polycystic ovary syndrome (PCOS). Conducting a single-arm study with 33 participants, we monitored acne symptoms, hirsutism, and menstrual irregularities over the course of eight weeks, along with hormone level assessments and safety evaluations.
Our findings suggested that Tracnil™ significantly reduced both inflammatory and non-inflammatory acne lesions. Additionally, it appeared to improve symptoms of hirsutism and help regulate menstrual cycles. While the exact mechanisms remain somewhat unclear, we believe that folic acid, in conjunction with the other components, plays a role in enhancing acne treatment responses, possibly by influencing receptor sensitivities to hormones.
Notably, throughout the study period, participants experienced minimal adverse reactions, and no severe side effects were identified. Even among those with normal hormonal levels, the combination therapy with myo-inositol and vitamin D3 underlined the potential benefits of Tracnil™ in managing dermatological signs associated with PCOS.
This research highlights the practicality of incorporating Tracnil™ into dermatological practice as a first-line approach for acne related to PCOS, broadening treatment options even in the absence of significant hormonal abnormalities.

Folate helps with isotretinoin pain
Successful Treatment of Isotretinoin Induced Musculoskeletal Pain by Vitamin B12 and Folic Acid.
We've discovered that folate supplementation may play a role in managing musculoskeletal pain associated with isotretinoin, a medication commonly used for acne treatment. In our investigation involving six patients suffering from nodulocystic acne, we closely observed their experiences after starting isotretinoin. Each patient reported developing pain in their muscles and joints, a side effect that can significantly affect quality of life.
The patients were treated with daily doses of folic acid and vitamin B12, leading to successful pain relief. This suggests that these supplements could be beneficial in alleviating discomfort without halting the use of isotretinoin itself. It’s important to note that while our findings are promising, extensive trials with larger sample sizes are still necessary to confirm these results.
As we move forward, we encourage our peers to consider offering B12 and folate to patients experiencing musculoskeletal pain from isotretinoin. This could help maintain treatment effectiveness while addressing uncomfortable side effects. Our study sheds light on an important aspect of acne treatment and patient care, urging further investigation into the benefits of these vitamins for overall treatment satisfaction.

No acne issues
Magnificent product; it provides me with plenty of energy. The B complex is effective and does not cause acne, plus its rich flavour and chewy texture make it very practical.
Acne is a common skin condition that affects people of all ages, though it's especially prevalent among teenagers and young adults. It occurs when hair follicles become clogged with oil and dead skin cells, leading to the formation of pimples, blackheads, and cysts. The main factors contributing to acne include excess oil production, hormonal changes, and the presence of bacteria on the skin. Acne can manifest in various forms, from mild cases with just a few breakouts to more severe forms that can cause significant inflammation and scarring.
Treatment for acne varies depending on its severity and can range from over-the-counter topical treatments like benzoyl peroxide and salicylic acid to prescription medications including retinoids and antibiotics. Lifestyle adjustments, such as maintaining a balanced diet and proper skin hygiene, may also contribute to managing and reducing breakouts. Despite being a common skin issue, the psychological impact of acne should not be underestimated, as it can affect self-esteem and overall quality of life.
Vitamin B Complex refers to a group of water-soluble vitamins that play important roles in cell metabolism and overall health. This group typically includes eight essential vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). Each of these vitamins contributes uniquely to various bodily functions, such as energy production, red blood cell formation, and nervous system function. For instance, B12 and folate are crucial in preventing anemia, while B6 is vital for brain development and function.
Many people can obtain their daily requirements of B vitamins through a balanced diet that includes whole grains, meats, eggs, nuts, leafy greens, and dairy products. However, certain groups—like vegetarians, pregnant women, and older adults—may benefit from supplementation to meet their nutritional needs. It's important to consult with a healthcare professional before starting any supplement regimen, as excessive intake of certain B vitamins can lead to adverse effects. Overall, ensuring adequate intake of Vitamin B Complex is vital for maintaining energy levels and supporting overall health.
While the relationship between Vitamin B Complex and acne is not definitively established, some evidence suggests that certain B vitamins may contribute to skin health. Vitamins B3 (niacinamide) and B5 (pantothenic acid), in particular, have been studied for their potential to improve skin barrier function and reduce acne severity. Niacinamide is known for its anti-inflammatory properties and can help regulate oil production, while pantothenic acid may assist in reducing inflammation and promoting skin repair.
That said, it's essential to approach vitamin supplementation with care. Taking high doses of certain B vitamins can sometimes lead to skin reactions or exacerbate acne for some individuals. Therefore, while incorporating Vitamin B Complex into your diet or skincare routine might improve overall skin health, it's best to consult a healthcare professional for personalized advice, especially if you're dealing with persistent acne issues.
Based on user reviews, the timeframe to see results from taking the supplement can vary significantly. For some individuals, positive effects on acne appeared relatively quickly; one user noted that their acne disappeared after just a month of use Read Review. Others experienced even faster relief, with one reviewer reporting that their acne stopped appearing within a day after switching to pantothenic acid Read Review.
However, it's important to consider that individual responses can differ, and some users noted adverse effects, including breakouts Read Review. A few reviewers indicated that caution might be needed, as increasing dosages exacerbated their acne Read Review. Therefore, while some may see improvement within a month or even a day, others may need to adjust their intake to prevent worsening symptoms. As always, consulting with a healthcare provider before starting any new supplement is advisable.
The scientific evidence surrounding supplements for acne is distinctly varied. Notably, the study on Tracnil™, a combination of myo-inositol, folic acid, and vitamin D3, demonstrated significant reductions in acne lesions among women with polycystic ovary syndrome (PCOS) [4]. Participants in the study experienced improvements in both inflammatory and non-inflammatory acne, suggesting that this supplement could be a valuable approach in managing acne linked to hormonal issues. Furthermore, the panthenol-enriched mask showed promising results in enhancing skin barrier function and reducing redness specifically for oily acne-prone skin [1].
On the other hand, research regarding vitamin B12 presents a more complex picture. While there's evidence of a correlation between vitamin B12 deficiency and the severity of acne in some populations [7], its supplementation has also been associated with acne flare-ups in certain cases [8]. This dual role indicates that while some individuals may benefit from certain supplements, others might experience adverse effects. Therefore, it is essential for individuals considering supplements to consult a healthcare professional, as the effectiveness can differ widely based on individual circumstances.
Users have reported significant improvements in their acne symptoms after incorporating pantothenic acid into their regimen. One reviewer noted that their acne completely disappeared within a month of use, attributing the success to a recommendation from their endocrinologist Read Review. Another individual experienced an even quicker turnaround, as they claimed their acne stopped appearing within just a day after switching to pantothenic acid, with existing blemishes fading over the following week Read Review.
On the other hand, not all experiences have been positive. Some users reported experiencing breakouts after taking similar vitamin combinations, leading them to adjust their dosages to manage the adverse effects Read Review. Additionally, a few noted that despite trying B12 alongside folic acid, they still encountered painful acne spots Read Review. Therefore, while many users saw demonstrable benefits, such as improved skin clarity and energy levels, individual responses can vary widely, highlighting the importance of careful dosage management.
Users have shared mixed experiences when combining this supplement with other vitamins for managing acne. Some individuals reported positive results, such as one reviewer who noted that switching to pantothenic acid eliminated their acne within a day, while another experienced complete resolution of their acne after a month of use following a healthcare professional's recommendation (review id='9cf2824f-326f-4985-9a14-3b65345f6648'; review id='48c12651-6896-441e-8448-8fb159461762'). However, other users experienced adverse effects when combining supplements. For instance, one user reported breakouts after taking a combination of B12 and folic acid, leading them to suggest taking these vitamins separately to mitigate acne flare-ups Read Review.
Furthermore, some reported recurring acne even with the use of supplements like B12, indicating a need for careful dosage management Read Review. While a few found certain combinations effective and well-tolerated, it's clear that individual responses vary significantly, and those prone to acne should consider their specific reactions when choosing to mix supplements.
Based on user reviews, the right dose of Vitamin B Complex for treating acne appears to vary significantly among individuals. Some users reported positive results with no acne side effects after taking B vitamins as prescribed, stating that their skin improved over time (see review-id: '9cf2824f-326f-4985-9a14-3b65345f6648', 'a00b4c17-be46-491c-ad19-b7bac94d5ccf'). However, others experienced adverse effects, including breakouts, when taking certain combinations of B vitamins, particularly B12 and folic acid. One user noted that reducing their B12 intake to once a week seemed to lessen the frequency of breakouts (review-id: '6af2c8ae-91fb-45b9-b942-17d1179e0634').
Moreover, several users recommend cautious usage, indicating that a daily high dose might cause issues for those already prone to acne. For example, one user suggested limiting intake to once weekly to prevent acne flare-ups (review-id: 'f511422b-41c1-4ab3-92f9-0096698e5018'). Overall, while some users found Vitamin B complex beneficial for their skin, others advised that adjusting the dosage might be necessary to avoid complications. Thus, it's clear that individuals may need to experiment with their dosing or consult a healthcare professional to determine the right balance for their skin health.

Vitamin B12 deficiency linked to acne
The Relationship Between Nutritional Anemia and Acne: A Case-Control Study.
We delved into the relationship between nutritional anemia, specifically vitamin B12 deficiency, and acne among young individuals in the Qassim Region of Saudi Arabia. Utilizing a case-control study design, we compared a group of people with acne to a control group of similar age and demographics. Our research involved Electronic Health Records from a local outpatient department, which allowed us to analyze a broad set of data.
Throughout our investigation, we found that those suffering from acne had a noticeably higher rate of vitamin B12 deficiency—38.6% in the acne group compared to the control group. However, while we saw this correlation, we did not establish a significant relationship between overall vitamin B12 levels and various blood parameters related to anemia. This means that although vitamin B12 deficiency was more prevalent in those with acne, it doesn’t necessarily imply that treating acne specifically with vitamin B12 will yield positive results.
Ultimately, our findings open the door for further investigation into how nutritional factors, particularly vitamin B12, might influence acne severity or development. We believe additional studies are necessary to confirm the possible connections we've observed and to explore potential treatment pathways.
We observed a fascinating case involving a 47-year-old man who developed a skin condition after starting vitamin B12 treatment for pernicious anemia. Just six weeks into his weekly injections of hydroxocobalamin, he experienced a sudden and widespread outbreak of inflammatory acne-like bumps on his face and trunk. This skin eruption was not only extensive but also caused significant itching and included comedones, commonly known as blackheads, particularly on his chest.
Upon closer examination, the medical team diagnosed him with a vitamin B12-induced acneiform eruption, which is different from typical acne vulgaris. This distinction came from several unique factors, including the patient's age, the sudden onset of the condition, and the presence of pruritus (itching) alongside a uniform type of lesions across non-seborrheic areas.
After normalizing his vitamin B12 levels, the hydroxocobalamin injections were stopped, and lymecycline—a type of antibiotic—was introduced. Remarkably, this led to a complete resolution of his skin lesions within three months. This case highlights how vitamin B12 can have an unusual, but significant impact on skin health, demonstrating that its effects are not just limited to its role in blood health but can extend into dermatological issues as well.
