We examined how vitamin D levels relate to acne and the potential connection with acne severity. By analyzing data from various studies, we found that 1,362 individuals with acne were compared against 1,081 healthy controls.
Our findings revealed that those with acne had significantly lower vitamin D levels compared to the healthy participants. Additionally, vitamin D deficiency was more prevalent among acne sufferers. Interestingly, we also observed a negative correlation between vitamin D levels and acne severity, suggesting that lower levels of this vitamin might be associated with more severe acne.
This evidence points to the possibility that vitamin D plays a role in acne development. However, while our results are compelling, they encourage further investigation into how vitamin D might influence acne severity and whether its supplementation could be beneficial for those affected by this condition.

We sought to understand the connection between vitamin D levels and acne, along with how vitamin D supplementation might help those suffering from this common skin condition. Our investigation included various studies from a range of databases, focusing on the serum levels of a specific form of vitamin D—25(OH)D—and the effectiveness of vitamin D supplements for acne patients.
In our findings, we discovered that individuals with acne generally had lower serum levels of vitamin D. Specifically, the data revealed a significant difference, with acne patients showing a standardized mean difference of -7.66 ng/ml in vitamin D levels compared to those without the condition. Importantly, the articles we reviewed also pointed out the potential for vitamin D supplements to serve as a therapeutic option for improving acne.
Overall, this research contributes valuable insights into how vitamin D may play a role in managing acne, suggesting that addressing vitamin D deficiency in patients could have positive outcomes for their skin health.

We investigated the intriguing link between vitamin D receptor (VDR) gene variations and acne in women experiencing polycystic ovary syndrome (PCOS). This study involved a careful comparison of 46 women with PCOS and 39 controls that matched in age and body mass index. We focused on acne and other skin conditions, along with measuring hormones and oxidative stress levels to understand their interplay.
The findings revealed that certain genetic variations in the VDR gene, particularly the FokI CC genotype, seemed to play a protective role against acne development. Women with this genotype were significantly less likely to experience acne compared to those with different genotypes. Moreover, we noticed that the TaqI dominant genotype also appeared to reduce oxidative stress levels in these patients.
Overall, our research provides compelling evidence suggesting that vitamin D’s influence, particularly through its receptor, could be an important factor in managing acne for women with PCOS. It's an exciting step towards understanding how our genes and environment can affect our skin health.

Finally a cure for my acne!!! After struggling with acne and scars for ages and trying numerous treatments, I decided to give this a go. By the third week, my face looked clearer than ever. Initially, the under-skin acne emerged quickly but then faded into whiteheads. For the first time, I have no active acne. Along with vitamin A, zinc, burdock root, and maca root capsules, I believe this vitamin D has had the most impact! I've even reduced my topical treatments, relying on a simple cleanse and moisturiser!

We investigated the effectiveness of Tracnil™, which combines myo-inositol, folic acid, and vitamin D3, on acne and other dermatological issues in overweight women with conditions related to Polycystic Ovary Syndrome (PCOS). Our findings showed that participants experienced a significant reduction in both inflammatory and non-inflammatory acne lesions within just eight weeks.
Notably, alongside improvements in acne, we observed positive changes in hirsutism—excess hair growth—and menstrual irregularities. Throughout the study, participants' safety was closely monitored, showing minimal adverse effects, while hormone levels remained stable despite our subjects initially having normal readings.
This leads us to believe that Tracnil™ may help regulate the body's response to sex hormones or perform other essential functions in managing PCOS symptoms, even when hormonal levels are not significantly abnormal. Therefore, we suggest that Tracnil™ could be an effective first-line treatment option for addressing dermatological concerns related to PCOS, simplifying treatment for those affected.

Vitamin D reduces acne inflammation
We conducted a double-blind, randomized controlled trial to explore how topical vitamin D affects acne vulgaris (AV). Our study involved 64 participants, who were split into two groups—one receiving a vitamin D treatment and the other a placebo. After 8 weeks, we observed significant changes in the inflammatory markers, specifically a reduction in interleukin-1 beta (IL-1β) levels, which plays a role in acne inflammation.
Participants in the vitamin D group showed a noticeable reduction in the number of inflammatory acne lesions compared to those using the placebo. This indicates that topical vitamin D can effectively lower inflammation associated with acne lesions.
It's essential to note that all participants also received topical adapalene, an established acne treatment. This could make it challenging to determine the exact effect of vitamin D alone. Nonetheless, the findings suggest that vitamin D has potential benefits in managing acne when included as part of a treatment regimen.

We embarked on a journey to understand how vitamin D might help with acne, particularly when combined with the standard treatment of benzoyl peroxide. Our study involved a well-structured approach, including a randomized, double-blind, placebo-controlled trial. This involved subjects diagnosed with mild to moderate acne, all applying benzoyl peroxide twice daily for 12 weeks.
During this time, participants were split into two groups—one receiving a weekly dose of 40,000 IU of vitamin D2, while the other group received a placebo. All subjects had low levels of vitamin D at the onset of the study, allowing us to investigate whether supplementation could make a difference.
As we analyzed the results, we noticed significant improvements in acne conditions for both groups. However, what stood out was the vitamin D2 group, which showed a statistically significant reduction in inflammatory lesions during the follow-up phase. Importantly, no adverse effects or unwanted biochemical changes were reported, highlighting the safety of this treatment.
Overall, our findings suggest that adding weekly vitamin D2 to a topical benzoyl peroxide regime could effectively reduce the likelihood of acne flare-ups in those with mild to moderate acne. While more extensive studies are needed to fully understand vitamin D's role in acne treatment, this adjunctive approach shows promise.

We conducted a study to explore the effectiveness of calcipotriol, a vitamin D analogue, in treating acne vulgaris. The research involved forty participants who received topical calcipotriol cream on one side of their face and adapalene gel on the other. This split-face approach allowed us to directly compare the effects of each treatment.
After two months, we observed a significant reduction in acne lesions on both sides of the face, with improvements noted in both physician and patient assessments. Interestingly, the density of inflammatory cells in the skin showed a notable decrease with calcipotriol, hinting at its potential anti-inflammatory properties.
While both treatments were effective, the results suggest that calcipotriol can be a valuable addition to acne therapy, providing similar benefits to adapalene but with a slightly different mechanism of action. Overall, this study opens new avenues for utilizing vitamin D in acne management.

We examined the effects of vitamin D levels on acne severity in our study, which included 50 acne patients and 30 healthy volunteers for comparison. Using the Global Acne Grading System, we graded the severity of acne in participants and measured body mass index (BMI) alongside serum 25(OH)D3 levels.
Our findings revealed that vitamin D deficiency was notably more common among those with acne—28% of acne patients were deficient, compared to only 6.7% of healthy individuals. While there wasn't a significant difference in average vitamin D levels between the two groups, we did observe a concerning trend. In particular, 60% of patients with very severe acne were deficient in vitamin D, which suggests a potential link between low vitamin D and increased acne severity.
Additionally, we noted that a high body mass index was also prevalent among those with severe forms of acne, highlighting a possible relationship between weight and skin health. However, the correlation between vitamin D levels and BMI was only statistically significant in very severe acne cases, indicating that further research is needed to clarify this relationship.
Ultimately, while we do see a connection between vitamin D deficiency and acne severity, the lack of a clear, consistent benefit requires more investigation before we can conclude that vitamin D treatment is an effective solution for acne.

We explored the relationship between vitamin D levels and acne by comparing 80 acne patients with 80 healthy individuals. Through our analysis, we found that vitamin D deficiency was noticeably more common among those with acne, highlighting a potential avenue for treatment. Almost 49% of the acne group was found to have low vitamin D levels, compared to just 22.5% in the control group.
Moreover, we observed a clear connection between the severity of acne and vitamin D levels. Specifically, lower vitamin D levels seemed to correlate with more severe inflammatory acne lesions. This prompted us to examine whether supplementing with vitamin D could lead to improvement. We treated participants with a vitamin D supplement for two months, and many reported a positive change in their skin condition.
However, it's important to note that our study had limitations, such as a small sample size for the supplementation group and the natural variability of acne. Overall, while there appears to be a link between vitamin D deficiency and acne severity, and some positive effects from supplementation, further research is needed to better understand and confirm these findings.
