Consider proximity - It is always more convenient and helpful to try to find a practitioner who is accessible. One of the things to do would be to have a list of the ones around the neighborhood and then follow up on each one to get a feel of who they are based on the relations they have had with their patients and the reviews there of.
Evaluate qualification - Not everyone who has a signboard and claims to be legitimate is; it is necessary to scrutinize the practitioners and ensure they are registered and licensed to carry out their practice. Ensure their overall licensing board recognizes them.
Be open - A dermatologist could very well be the new best friend; they are able to look at the skin problem from all angles and not only diagnose it but also help in determining the source. They are such an asset that even for those seeking to find out the legitimacy of skin products or the kind of diet they need to have in order to have flawless skin, the trip to the clinic may turn out to be more helpful than they thought.
It is secondary - Much as the medical appointment may take precedence over a trip to the general practitioner, this ought not to be the case; they are to serve as a referral base for the skin conditions that require more attention than a general physician may be in a position to give.
