Yangshengtang natural vitamin E capsule is externally applied to oily skin to remove acne marks. How many times a week can you apply it? I 17 years old. Will there be any side effects if I take it orally? Yangshengtang natural vitamin E is a health care product with no side effects. One tablet a day is enough. It is recommended to buy in shopping malls or regular pharmacies and specialty stores. If you have acne marks for a long time, such as 1 year or more, oral or topical vitamin E is ineffective. It is recommended to use products specifically for acne marks for treatment!
