We explored the effectiveness of vitamin E alongside isotretinoin, a common treatment for severe acne. In an investigator-blinded, randomized study involving 82 patients, participants were divided into two groups. One group received isotretinoin alone, while the other combined it with 800 IU of vitamin E, over a period of 16 weeks.
Our main goal was to determine whether vitamin E could reduce the side-effects associated with isotretinoin, which are often bothersome for patients. Throughout the study, we assessed various mucocutaneous side effects, such as facial dryness and redness, as well as changes in serum lipid and liver enzyme levels.
Ultimately, we found no significant difference in the incidence or severity of side effects between the two treatment groups. This indicates that vitamin E did not provide any noticeable benefit when added to isotretinoin therapy for acne vulgaris.
While vitamin E is often suggested as a remedy to lighten the side effects of medications, our findings suggest that its use alongside isotretinoin may not be helpful.

Vitamin E ineffective for acne therapy
Concomitant administration of vitamin E does not change the side effects of isotretinoin as used in acne vulgaris: a randomized trial.
We conducted a study to assess whether vitamin E could help reduce the side effects associated with isotretinoin, a common treatment for severe acne. In this double-blind, randomized trial, we assigned 140 participants to receive either isotretinoin paired with a daily dose of 800 IU of vitamin E or a placebo over 20 weeks.
We closely monitored the participants for any side effects such as dry eyes and dry lips. Despite our hopes, the addition of vitamin E did not show any significant improvement in the side effects experienced by those taking isotretinoin. In essence, we found that vitamin E had little to no effect in alleviating the discomfort associated with isotretinoin treatment for acne.
This study thoroughly evaluated the potential benefits of combining vitamin E with isotretinoin but ultimately concluded that the vitamin does not mitigate the adverse side effects of the medication. It’s clear that vitamin E alone might not be the miracle solution for easing isotretinoin side effects as some had hoped.

Vitamin E may reduce acne lesions
Addressing Free Radical Oxidation in Acne Vulgaris.
We explored the effects of vitamin E on acne by conducting an open-label study with 17 patients who had mild to moderate acne vulgaris. Over eight weeks, these patients followed a standard regimen involving salicylic acid and benzoyl peroxide, with the addition of topical vitamin E in sunflower seed oil.
Throughout the study, we observed that all participants experienced clinical improvements, including a reduction in the number of acne lesions. Interestingly, significant improvements were noted as early as Week 2, indicating that vitamin E may play a beneficial role in managing acne symptoms. Furthermore, patients reported positive feedback regarding the ease of application and tolerability of the treatment.
Although we cannot definitively say vitamin E is a cure for acne, our findings suggest that it may help alleviate some symptoms when used alongside established treatments. This research sheds light on the potential of topical antioxidants like vitamin E in the ongoing battle against acne, inviting further exploration into their effectiveness and role in skincare.

With vitamin A, this combination yielded remarkable skin improvement results. After suffering from acne for a decade, the vitamins A, E, and C resolved my issues within two weeks. Although vitamin C speeds up results, I now have flawless skin, bright eyes, and healthy hair.
A randomized, double-blind, placebo-controlled trial to determine the efficacy and safety of lactoferrin with vitamin E and zinc as an oral therapy for mild to moderate acne vulgaris.
We observed how a combination of lactoferrin, vitamin E, and zinc might affect mild to moderate acne. In a rigorously designed study, 168 participants aged 13 to 40 were randomly assigned to receive either a treatment capsule containing these ingredients or a placebo twice a day over the course of three months.
The results showcased that those taking the lactoferrin combination saw a notable reduction in acne lesions—an early 14.5% improvement after just two weeks, reaching a maximum of 28.5% reduction by week ten. While vitamin E was part of the treatment, it’s essential to understand that it was combined with lactoferrin and zinc. This means we can't pinpoint vitamin E's specific role in the improvements observed.
Throughout the trial, no adverse effects were reported, reinforcing the safety of the treatment. Overall, this study presents promising findings for those struggling with mild to moderate acne, particularly with the effective dosing of lactoferrin alongside vitamin E and zinc.

Vitamin E shows positive acne effects
Modulation of sebum oxidation and interleukin-1α levels associates with clinical improvement of mild comedonal acne.
We looked into how a combination of RetinSphere® and vitamin E affects mild comedonal acne (MCA). In our study, we measured important factors like sebum oxidation and inflammatory markers before and after treatment in 18 patients with MCA and 10 healthy controls.
Our findings showed that while the amount of sebum and squalene was similar before treatment between the groups, patients with MCA had higher levels of lipid peroxidation and oxidized squalene. These elevated markers contribute to inflammation and acne formation.
After 4 weeks, there was a notable decrease in oxidized lipids and inflammation markers in the lesions, bringing them in line with unaffected areas. These changes were accompanied by visible clinical improvement in the patients by the 8-week mark.
Yet, it’s important to recognize that while vitamin E was part of the treatment mix, this study did not isolate its specific effects. Thus, while we observed positive results, we cannot definitively attribute all improvements directly to vitamin E alone.

Vitamin E aids isotretinoin therapy
A dietary supplement to reduce side effects of oral isotretinoin therapy in acne patients.
We investigated the potential of a dietary supplement containing vitamin E and other ingredients to alleviate side effects from oral isotretinoin therapy in acne patients. The study involved forty-eight participants with nodular acne, divided into two groups. One group received isotretinoin combined with the supplement, while the other only received isotretinoin for six months.
Our findings revealed that the group taking the dietary supplement reported fewer side effects, experiencing less dryness and redness of the skin, as well as improved hydration levels. Participants also showed increased adherence to their treatment regimen when supplemented, which is encouraging for those battling the challenges of acne and its treatment.
The supplement's formulation, enriched with vitamin E and other antioxidants, seems to support skin health during isotretinoin therapy, helping to mitigate common discomforts like dry skin and erythema. This suggests that vitamin E plays a beneficial role when included in a combination supplement, enhancing overall treatment experience for patients undergoing isotretinoin therapy.

Vitamin E linked to acne severity
Does the plasma level of vitamins A and E affect acne condition?
We aimed to understand how plasma levels of vitamins A and E relate to acne conditions. To do this, we compared vitamin concentrations in 100 newly diagnosed acne patients with 100 healthy individuals of similar age. We utilized high-performance liquid chromatography to ensure accurate measurements, and acne severity was evaluated using the Global Acne Grading System.
Our findings revealed that acne patients had noticeably lower levels of both vitamin A and vitamin E compared to the controls. Specifically, vitamin A levels were 336.5 µg/L for patients versus 418.1 µg/L for healthy individuals, while vitamin E levels were 5.4 mg/L in patients against 5.9 mg/L in controls.
Additionally, we observed a clear link: as the severity of acne increased, the plasma levels of vitamins A and E tended to decrease. This suggests that these vitamins may play a role in the condition's progression, highlighting their potential importance in acne management.
However, it's essential to consider that while the correlation between low vitamin levels and acne severity is significant, the study does not confirm that vitamin E supplementation alone can effectively treat acne.

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 E is a fat-soluble nutrient that plays a crucial role in various bodily functions, primarily acting as an antioxidant. This means it helps to neutralize free radicals, which are unstable molecules that can cause oxidative stress, leading to cellular damage. Vitamin E is not just one compound, but a group of several related compounds, with tocopherols and tocotrienols being the most studied forms. These compounds are found in various foods, including nuts, seeds, and green leafy vegetables, making it relatively easy to obtain sufficient amounts through a balanced diet.
Research suggests that Vitamin E may contribute to immune function, skin health, and the overall maintenance of cardiovascular health. While most people can get enough Vitamin E from their diet, supplements may be necessary for those with specific deficiencies or conditions that impair absorption. However, it’s important to consult a healthcare provider before starting any supplement regimen, as excessive intake of Vitamin E can lead to adverse effects. Overall, maintaining adequate Vitamin E levels is essential for promoting long-term health and preventing potential deficiencies.
Vitamin E is often touted for its potential benefits in skin health, including acne management. This fat-soluble antioxidant can help reduce oxidative stress and inflammation in the skin, which may be beneficial for those dealing with acne. Additionally, it’s known for its moisturizing properties, potentially aiding in the repair of the skin barrier, which is crucial for those suffering from acne. However, while some users report improvements in their skin texture and appearance when using Vitamin E topically, scientific studies supporting its effectiveness specifically for treating acne are limited.
It's important to note that while Vitamin E may provide some benefits, it is not a standalone solution for acne treatment. Individuals struggling with persistent acne should consult with a dermatologist to discuss a comprehensive skincare regimen that may include other proven treatments, such as benzoyl peroxide, salicylic acid, retinoids, or prescription medications. Always conduct a patch test prior to introducing any new product into your routine, as some individuals may experience irritation or breakouts from oilier formulations.
Based on user reviews, the time it takes to see results from taking supplements for acne can vary, but many express noticeable improvements within a few weeks to a few months. For instance, one reviewer indicated that their acne cleared up entirely after three weeks of taking a vitamin regimen (Read Review). Another user reported that their skin, which had suffered from persistent acne for a decade, showed significant improvements within just two weeks using a combination of vitamins A, E, and C (Read Review).
However, some users experienced a longer timeframe before achieving clear skin. One reviewer shared that it took three months to stop experiencing acne altogether, but they were pleased with the quality and effectiveness of the supplements during that period (Read Review). Overall, while individual results may vary, several users suggest that improvements can often be seen as early as two weeks, but a timeframe of up to three months may be necessary for complete results.
Vitamin E has been explored in various studies for its potential effects on acne, but the findings present a mixed bag. One study noted that patients with acne had lower serum levels of vitamin E compared to healthy controls, hinting at a possible link between vitamin E status and skin health [1]. Another study indicated that when combined with lactoferrin and zinc, vitamin E contributed to significant improvements in acne lesions among participants, with reductions noted as early as two weeks [2]. However, it’s crucial to contextualize these results, as the benefits seen are not solely attributed to vitamin E alone.
Several studies focusing on the use of vitamin E alongside isotretinoin—a common treatment for severe acne—did not find significant advantages from the addition of vitamin E. In these trials, participants reported persistent side effects regardless of whether they supplemented with vitamin E or not [12][15]. While there are indications that vitamin E may alleviate some specific symptoms of acne, definitive conclusions regarding its effectiveness in treating acne on its own remain elusive. Ultimately, while vitamin E could play a supportive role in acne management, particularly when combined with other treatments, further research is needed to establish clear benefits.
Users report various improvements in their skin symptoms after taking vitamins, particularly for acne. For example, one user indicated that their persistent acne disappeared entirely within just three weeks of taking a vitamin regimen (Read Review). Another reviewer, who struggled with acne for a decade, experienced significant improvement in only two weeks after starting a combination of vitamins A, E, and C, leading to flawless skin and overall enhanced beauty (Read Review).
Other users also noted significant enhancements. For instance, after two weeks of using vitamin E, one reviewer observed their acne had cleared and oiliness reduced, leaving their skin looking healthy (Read Review). Meanwhile, a different user shared their positive experience of reduced facial redness and fewer acne spots after two weeks of supplementation, although they were unable to complete the regimen (Read Review). However, results can vary widely among individuals; some found it took up to three months for almost complete resolution of their acne issues (Read Review). Overall, while many users achieved encouraging results swiftly, others experienced a more gradual improvement.
Users have reported a range of experiences when combining acne supplements, particularly vitamins A, E, and C, with other treatments. One reviewer highlighted a significant improvement after two weeks of taking a combination of vitamins A, E, and C, stating that it resolved their decade-long battle with acne and led to a flawless complexion (Read Review). Another user noted that after using vitamin E for two weeks, they experienced not only a disappearance of acne but also reduced oiliness, leaving their skin looking healthy and vibrant (Read Review).
Moreover, several reviewers emphasized the effectiveness of these vitamins in conjunction with other treatments. For example, one user mentioned how the combination helped to tackle acne and facial redness, resulting in visible improvements within just two weeks, despite being unable to complete the full regimen due to a surgical procedure (Read Review). There are also comments on the importance of selecting effective brands, with one reviewer indicating that a particular vitamin E product significantly reduced the likelihood of acne and improved the overall health of their skin compared to others they had tried (Read Review). Overall, many users affirm that combining these supplements with proper skincare can lead to substantial improvements in managing acne.
Based on user reviews, it appears that there is a consensus around the efficacy of Vitamin E for treating acne, particularly when taken in capsule form. Users report positive outcomes, noting that taking one capsule daily led to significant improvements in their skin condition, including reduced acne and overall healthier skin. For example, one user mentioned that after two weeks of taking a single capsule daily, their acne disappeared, and their skin looked beautiful Read Review. Another user saw remarkable results when combining vitamins A, E, and C, suggesting that these vitamins can work synergistically for enhanced effects Read Review.
Several reviewers spoke about experiencing clearer skin and reduced redness after consistent use over varying durations. One user stated that after three months, their skin was nearly irritation-free and acne had completely stopped Read Review. Another noted that even after just two weeks, they had significantly fewer acne spots Read Review. While exact dosing may vary, the general suggestion leans towards taking one capsule daily to see optimal results.

Vitamin E levels lower in acne
Serum vitamin E levels and chronic inflammatory skin diseases: A systematic review and meta-analysis.
We examined the relationship between serum vitamin E levels and acne as part of a broader investigation into chronic inflammatory skin diseases. Our analysis included a number of studies that focused on vitamin E in patients, comparing their serum levels with those of healthy individuals.
The findings revealed that patients with acne had significantly lower levels of serum vitamin E compared to controls. This supports the idea that vitamin E might play a role in skin health, although we must note that the study did not delve into how vitamin E treatment specifically improves acne.
In short, while the lower vitamin E levels in acne patients are noteworthy, the study leaves us without conclusive evidence of vitamin E’s direct impact on treating acne. We highlight the importance of evaluating vitamin E status as part of managing skin health across various conditions, including acne.
