Sir, i am 29 yrs, 2 months before i got burns of hot spills of oil on face, but now marks are still there. I applied several creams but no improvement.

For the marks left on your face, you can try using a cream containing hydroquinone, such as Melalite cream. Apply a thin layer on the affected areas once daily at night. Additionally, you can also use a cream with tretinoin, such as Retin-A cream, to help improve the texture of the skin.
