Agree with the above to give things some time to fill in and new hairs to develop. Your hair grows in cycles, some of the follicles are dormant right now but will start to grow soon to help fill in some of the areas you are concerned about. At 26 your beard is still developing, so give things time to fill in and see how it looks after about 13 weeks or so, look around here a bit and you will find plenty of journeys that started off slowly and now how beautiful beards.
