how can a sixteen year old male get flawless skin🤔?

It's difficult for any 16 year old to have flawless skin. Didi recommends the basics - staying hydrated, washing your face daily with mild soap, avoiding too much caffeine and fatty/greasy foods, and regular exercise. If you have really bad acne - not just here and there (nomal for teenagers), but all over, try talking to a dermatologist (skin doctor). There are medicines that could help, but such medicines are not without side effects, so should be used only under the guidance of a doctor!
