Prayer for the Healing of My Sister's Acne

I humbly ask your prayer for my sister, who suffers from skin disease. She has severe acne all over her face. She doesn’t have enough confidence to go outside. She always stays in our house or her room with a guest. I am worried about her situation. I want her to have the courage to face the people around us. Please pray that God heals her from this disease so she can return to her everyday life again.
Pray that the doctor will give her the best medication.
I will appreciate all your prayers. Thank you so much! And God bless
