Specific I Need background to be pure white

[Hayat.Zoghbi]

Hi, i would like to have the background white so i can add text next to the photo later, and i want the image of the pharmacist to be brighter and look fresh, with less shadows on the shirt and smoother finish. ive been trying soo hard and i dont know how to do it.
any help would be appreciated. thank you in advance
