Services & Specialties

What to Expect at The Maas Clinic San Francisco

Your first visit starts with a consultation where a physician-led provider reviews your goals and assesses your facial anatomy. For neurotoxins like Botox or Dysport, treatment is quick — usually around 15 minutes — with results developing over the following several days. For fillers, you'll discuss how many syringes are needed and what to expect for swelling and downtime. The provider marks injection points, treats the areas, and reviews aftercare such as avoiding heavy exercise and not rubbing the treated zones. Before booking, it's worth confirming provider credentials, asking about total cost, and noting any medications or allergies to mention at the visit.
