If someone says they are a “Board Certified Physician” then your first question should be, “Boarded in what?” Only dermatologists are extensively trained in the skin, hair and nails. If you want help with your skin, then a dermatologist's office is your best choice. Board Certification means certified by an official Board, but it doesn't tell you which Board. Which board has done the certification is highly relevant when you are shopping for the best skin care expert.
Aesthetic Medicine is not recognized as a specialty by the American Board of Medical Specialists. Dermatology cannot be learned on a weekend course. Certification matters.
The American Board of Dermatology requires a medical doctorate degree, a one year internship, followed by a 3 year (full-time) residency in dermatology. There is a national Board exam at the end of those 3 years, followed by continuous medical education for maintenance of ABD Board certification. Medical doctors who are Board Certified in Dermatology or Plastic Surgery come from the top of their medical school classes.
A clinic cannot be “Board Certified”, only an individual can. Some people have created their own Boards, for the purpose of saying they are board-certified, but these boards do not have the same high standards as ABMS.
