Can you suggest a good physical sunscreen with high zinc oxide content? My upper lip is very dark. Can I use hydroquinone on it? What antioxidants should I take for good skin health?
For a dark upper lip, use a physical sunscreen with zinc oxide to protect the skin from sunlight and prevent further darkening. Hydroquinone can help lighten the area, but should be used only after a doctor's advice, as it may irritate. Eating fruits, vegetables, and nuts, and staying hydrated, helps improve overall skin health.
