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.

Eicosapentaenoic acid shows promiseAntibacterial activity of long-chain polyunsaturated fatty acids against Propionibacterium acnes and Staphylococcus aureus.
We aimed to explore the effectiveness of eicosapentaenoic acid (EPA) along with other long-chain polyunsaturated fatty acids (LC-PUFAs) in treating acne and superficial infections caused by the bacteria Propionibacterium acnes and Staphylococcus aureus. In our investigation, we found that these fatty acids exhibited antibacterial properties, with a range of effectiveness against the two types of bacteria.
The study revealed that P. acnes showed more sensitivity to the growth-inhibiting effects of LC-PUFAs compared to S. aureus. Interestingly, while these compounds were capable of stopping P. acnes growth, they were only bactericidal, meaning they could kill S. aureus. Our findings also included the discovery of the antibacterial activity in previously unreported fatty acids such as 15-hydroxyeicosapentaenoic acid (15-OHEPA) and 15-hydroxyeicosatrienoic acid (HETrE).
Additionally, we noted that when S. aureus was exposed to these fatty acids, the bacteria were effectively killed within a short timeframe, specifically between 15 to 30 minutes. Combining these LC-PUFAs with established treatments did not reduce their effectiveness and revealed potential potentiation of action, particularly in combinations with commonly used acne medications like benzoyl peroxide and neomycin.
In conclusion, our observations suggest that eicosapentaenoic acid and other LC-PUFAs may be valuable new options for treating skin infections caused by P. acnes and S. aureus, especially when used alongside conventional therapies. However, further studies are needed to fully understand their potential in clinical settings.
