It's possible to reduce black spots and to improve facial appearance by reducing lines on your forehead.
But the treatment needs proper prescription from a dermatologist.
DO NOT APPLY any creams/ointment by yourself or from medical store guy, which might sometimes cause contact dermatitis/ increase the problem if they contain high potent steroids and damage the skin.
Next Steps
consult me online/ any Dermatologist.
