Indented scar removed between my eyebrows and the stitches broke. What would you suggest to help the area heal? (photo)

I have a scar for 40 years between my eyes, . I have it removed by surgical scar revision but after 2 days the stitches broke due to putting sun screen on my fore head, its is very thick.. It has been 6 weeks now and I have been using the silicon gel and tape about 1 month everyday, and my doctor suggested that I should do the laser treatment to make it look better. Should I wait until its totally healed ? how much longer should I wait and what is the next step? will the laser help ?
