Hello and welcome to healthcaremagic
Pigmentation seems to be your main concern.
Sun protection is an essential part of treatment in the management of pigmentation over face because face is always exposed to the sun. I would suggest you to use a broad spectrum sunscreen, that which offers both UV A as well as UV B protection, throughout the day.
You could use a cream containing one or more of the skin lightening agents e.g
glycolic acid,
kojic acid, arbutin,
hydroquinone, azaleic acid etc once or twice daily to lighten the pigmentation.
While glycolic acid exfoliates existing pigment; kojic acid, hydroquinone, azaleic acid etc inhibit melanogenesis/synthesis of new pigment and therefore have a synergistic action owing to different mechanism of action.
Along with topical treatment, you could also take a few chemical peeling sessions (6-8) from a
dermatologist. The commonly performed peels for facial pigmentation are glycolic acid peel, kojic acid peel and TCA (
Trichloroacetic acid) peel.
Hope this helps
