Zinc supplements have garnered attention in recent years for their potential role in managing acne. Research indicates that zinc plays a crucial role in skin health, primarily due to its anti-inflammatory properties and its ability to regulate oil production in the skin. Acne is often exacerbated by excess sebum production, and zinc may help mitigate this by influencing the activity of sebaceous glands. Additionally, zinc is essential for immune function and wound healing, which can be beneficial for individuals suffering from acne lesions.

Several studies have suggested that zinc supplementation can lead to a reduction in acne lesions. For instance, a review published in the "Journal of Dermatology" found that oral zinc supplementation significantly reduced the number of acne lesions in individuals with moderate to severe acne. The typical dosage used in studies ranges from 30 mg to 150 mg of elemental zinc per day, with many studies suggesting that a dose of around 30 mg is effective and generally safe for most individuals. However, it is important to note that excessive zinc intake can lead to toxicity and adverse effects, such as nausea, diarrhea, and interference with the absorption of other essential minerals like copper.

When considering zinc supplementation, it is crucial to consult with a healthcare provider to determine the appropriate dosage based on individual health needs and conditions. They can also help monitor for any potential side effects or interactions with other medications.

Regarding the claim that vitamin E is more effective when taken orally compared to topical application, there is some merit to this assertion. Vitamin E is a potent antioxidant that helps protect skin cells from oxidative stress and may aid in skin healing. While topical vitamin E can provide localized benefits, such as moisturizing and reducing the appearance of scars, systemic absorption through oral supplementation may offer broader benefits for skin health. Studies have shown that oral vitamin E can improve skin elasticity and hydration, and it may also enhance the skin's overall appearance.

However, the effectiveness of vitamin E, whether taken orally or applied topically, can vary based on individual skin types and conditions. The recommended dietary allowance (RDA) for vitamin E is about 15 mg per day for adults, and it is generally considered safe when consumed in food sources or supplements within recommended limits.
In conclusion, zinc supplements can indeed play a role in reducing acne, particularly in individuals who may be deficient in this mineral. A dosage of around 30 mg per day is often effective, but it is essential to consult with a healthcare professional before starting any supplementation. As for vitamin E, while oral supplementation may provide systemic benefits, topical applications can still be valuable for localized skin issues. Ultimately, a holistic approach that includes a balanced diet rich in antioxidants, proper skincare, and consultation with healthcare providers is the best strategy for managing acne and promoting overall skin health.
