I have a scar on my face what could you recommend to reduce the appearance?

Laser Scar Treatment: Laser therapy can work on all types of scars, including keloids (raised scars), atrophic scars (pock-marks), and hypertrophic scars (raised, pin-point scars). Keep in mind that laser scar removal is not always the best idea, as those with severe acne, rosacea or other skin disorders may experience unwanted side effects such as severe pain and redness outside of what might normally be expected.

Improve, not remove.: Scars cannot be removed but there is a large variety of techniques to improve their appearance, both surgical and non-surgical. They also improve with time. See a dermatologist or board-certified plastic surgeon to evaluate your options. Good luck!
