Vitamin C serum, sunscreen, anti oxidant capsule
Welcome to ask a doctor service
I have gone through your query.
For glow I would recommend you to apply vitamin C serum on the face at night along with regular application of a broad spectrum sunscreen ( faceguard sunscreen gel) on the entire face during the day time.
Also take an anti oxidant like capsule Antoxid HC once daily for 10-12 weeks.
Besides this take plenty of fruits, vegetables and water.
I hope to have answered your query and would be happy to answer any further queries.
