When it comes to determining the appropriate daily intake of Vitamin C for smokers, the general consensus among health professionals is that smokers require a higher amount of Vitamin C compared to non-smokers. This is primarily due to the oxidative stress and damage caused by smoking, which depletes Vitamin C levels in the body. Research suggests that smokers may need an additional 35 mg of Vitamin C per day on top of the recommended dietary allowance (RDA). The RDA for Vitamin C is 90 mg for men and 75 mg for women, which means that smokers should aim for at least 125 mg for men and 110 mg for women daily.
In your case, since you mentioned smoking a pack of cigarettes a day, it is estimated that you would need around 500 mg of Vitamin C daily. This figure is based on the idea that each cigarette can deplete approximately 25 mg of Vitamin C. However, it’s important to note that while increasing Vitamin C intake can help mitigate some of the oxidative damage caused by smoking, it does not counteract all the harmful effects of smoking on the body. Therefore, considering reducing your smoking habit could be beneficial for your overall health.

Regarding skin care for individuals with seborrheic dermatitis (脂漏) and rosacea (酒糟), the choice between Vitamin E and B vitamins can depend on specific skin conditions and individual responses. Vitamin E is known for its antioxidant properties and can help protect the skin from oxidative damage. It also has moisturizing properties, which can be beneficial for skin that is dry or irritated. On the other hand, B vitamins, particularly B3 (niacinamide), can help improve skin barrier function, reduce inflammation, and enhance the overall appearance of the skin.
For individuals with seborrheic dermatitis, which is characterized by red, flaky patches on the skin, Vitamin E may provide some relief due to its soothing properties. However, it’s essential to consult with a dermatologist to determine the best course of action, as some individuals may react differently to various supplements.
In summary, smokers should aim for a higher intake of Vitamin C, ideally around 500 mg daily, to help counteract the oxidative stress caused by smoking. For skin care, both Vitamin E and B vitamins can offer benefits, but it is advisable to consult with a healthcare professional to tailor a regimen that suits your specific skin conditions. Additionally, focusing on a balanced diet rich in fruits and vegetables can provide a natural source of these vitamins and contribute to overall skin health.
