Docosahexaenoic acid reduces acne riskThe causal association between polyunsaturated fatty acids and acne: A two-sample Mendelian randomization study.
We investigated the relationship between docosahexaenoic acid (DHA), a type of polyunsaturated fatty acid (PUFA), and the occurrence of acne. Using a method called Mendelian randomization, we looked at how genetic variations associated with DHA might influence acne development in large groups of participants, including over 115,000 individuals from the UK and nearly 364,000 of Finnish ancestry.
Our findings revealed that higher levels of DHA are actually linked to a lower risk of developing acne. Specifically, we found that a significant increase in DHA levels or its proportion compared to total fatty acids corresponded with a reduced likelihood of acne. In contrast, higher levels of linoleic acid (LA), another type of PUFA, were associated with an increased acne risk.
This suggests that balancing our intake of these fatty acids might be important for skin health. Notably, the results pointed towards a genetic connection involving the FADS1 gene, which appears to play a role in how these fatty acids affect our skin.
In conclusion, increasing DHA could be beneficial in protecting against acne, while excessive linoleic acid might have the opposite effect. Overall, our study highlights the importance of these fatty acids in understanding acne risk better.

DHA improves acne severityExploring the potential of omega-3 fatty acids in acne patients: A prospective intervention study.
We explored the potential benefits of docosahexaenoic acid (DHA), a type of omega-3 fatty acid, in treating acne. Over 16 weeks, 60 participants followed a Mediterranean diet paired with algae-derived DHA and eicosapentaenoic acid (EPA) supplementation. We aimed to boost their omega-3 levels and observe any changes in their acne severity.
Remarkably, our study found that nearly all participants started with a deficiency in omega-3 fatty acids. After the dietary and supplementation intervention, the average omega-3 index rose significantly, indicating improved levels of DHA and EPA. More importantly, participants experienced notable reductions in both inflammatory and non-inflammatory acne lesions.
While a few individuals reported that their skin appearance worsened, the collective quality of life among participants improved, especially for those with papulopustular acne. They also became more aware of dietary triggers and made healthier choices, like reducing cow's milk and dairy intake. Overall, we saw a promising link between increased omega-3 levels and improved acne outcomes.

Omega-3's effect on acneThe adjuvant treatment role of ω-3 fatty acids by regulating gut microbiota positively in the acne vulgaris.
We aimed to understand how omega-3 fatty acids could help manage acne by potentially changing our gut bacteria. In our study, we grouped untreated acne patients and saw how those who received omega-3 supplements fared compared to those who did not over the course of 12 weeks.
Additionally, we worked with rats that had an acne model. We treated these rats with isotretinoin, omega-3 fatty acids, or a combination of both. Afterward, we transferred the colonic contents from the treated rats to a separate group of rats with acne to further assess the impact.
By using the Global Acne Grading System to evaluate the patients, we found that omega-3 fatty acids improved the diversity of gut microbiota and positively influenced the strains of bacteria present. This resulted in decreased inflammation and fewer comedones in rats, while in patients, we noticed an increase in beneficial gut bacteria that produce butyric acid and an overall improvement in acne severity.
Our findings suggest that omega-3 fatty acids may play a role in alleviating acne symptoms by modifying gut bacteria, but more research is needed to isolate their specific effects from other treatments like isotretinoin.

Docosahexaenoic acid aids acne treatmentEffect of dietary supplementation with omega-3 fatty acid and gamma-linolenic acid on acne vulgaris: a randomised, double-blind, controlled trial.
We conducted an interesting study to understand how docosahexaenoic acid (a type of omega-3 fatty acid) influences acne treatment. Over 10 weeks, 45 participants with mild to moderate acne were divided into three groups: one receiving omega-3 fatty acids, another taking gamma-linoleic acid, and a control group.
Remarkably, those who received omega-3 and gamma-linoleic acid experienced significant reductions in both inflammatory and non-inflammatory acne lesions. This improvement was reflected in participants’ personal assessments, highlighting their positive experiences with the treatment.
Additionally, we observed that laboratory tests showed decreased inflammation and a reduction in levels of interleukin-8, a marker linked to acne inflammation. Importantly, there were no serious side effects reported, which is encouraging for considering these supplements as adjunct treatments for acne.
Overall, our findings suggest that incorporating omega-3 fatty acids, like docosahexaenoic acid, may be beneficial for individuals struggling with acne, providing a natural option alongside conventional treatments.

Omega-3's unclear acne effectivenessThe role of vitamins and nutrients in rosacea.
We examined the effects of omega-3 fatty acids on acne, particularly through its role in managing symptoms related to ocular rosacea. Our investigation revealed that while omega-3 showed promising results for alleviating dryness and discomfort in those with ocular rosacea, its direct impact on acne itself remains unclear.
Interestingly, we found that 64% of patients with ocular rosacea benefited greatly from omega-3 supplementation during the study. However, since the focus was primarily on ocular symptoms rather than acne lesions, we couldn't definitively conclude that omega-3 is effective for acne treatment. Further research is needed to fully understand how omega-3 may influence acne symptoms and whether it could be a valuable addition to acne treatment regimens.
Overall, it seems omega-3 has potential for specific skin concerns, but it hasn't directly proven its effectiveness for acne. This is something we'd like to explore more in the future to help those seeking alternative treatment options.
