Telemedicine Visits
We have been offering telemedicine visits since March, 2020. Although, we re-opened 2 months later in May, 2020 with the rest of the world for in-person visits, we still continue conducting telemedicine visits for patients who are interested in them, such as elderly patients who would like to avoid leaving the house for medical reasons, or working folks who like to schedule televisits to accommodate their busy lifestyle.
We use telemedicine visits to triage medical problems. If the problem brought up during the telemedicine visit, is concerning for infection or cancer or equivocal, then we will invite you to come in ASAP for a live evaluation and likely biopsy/ procedure.
If the issue evaluated during telemedicine visit is benign, then we are happy to reassure you, and that will save you a trip to the office.
To schedule a regular visit or a telemedicine visit, please call 508-444-6989

What’s up with sunscreens? By Maria Azizian MD FACS
June 2019
A lot of my patients have been inquiring about the recent data from JAMA (Journal of the American Medical Association) regarding the safety of sunscreens.
But, first, let’s do a little review:
What do sunscreens do?
1) Decrease skin cancer
2) Decrease aging (wrinkles)
3) Prevent sunburn
There are 2 types of sunscreens:
1) Physical or Barrier Sunscreens have 2 ingredients, titanium dioxide and zinc oxide.
Physical sunscreens create a protective barrier, protect against both UVA and UVB, and they do not absorb into the skin. They are recommended for people with sensitive skin and for children.
2) Chemical Sunscreens are composed of many ingredients that are absorbed through the skin. They also protect against UVA and UVB.
In summary, the physical sunscreens reflect, and chemical sunscreens absorb. The physical sunscreens tend to be white and somewhat thick, unlike sleeker in texture chemical sunscreens.
Pertinent to chemical sunscreens, what level of absorption matters?
According to FDA, the blood level of greater than 0.5 ng/mL of given ingredient matters in terms of its potential effect.
In a recent study, healthy volunteers were kept indoors without sunlight for a week, and sunscreen was applied 4 times a day for 4 consecutive days.
Throughout their stay, their blood was tested for levels of avobenzone, oxybenzone, octocrylene, and ecamsule (the most common active ingredients).
The blood level of each chemical was shown to reach much higher than than 0.5 ng/ mL.
At this point, it is not known what harm these ingredients may cause.
According to the FDA, 12 sunscreen ingredients lack enough data to support whether they are completely safe. They are cinoxate, dioxybenzone, ensulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, and avobenzone.
Among the concerns are that oxybenzone ”is absorbed through the skin to a greater extent than previously understood”.
There are questions about its potential to be an endocrine disrupter, a chemical that can cause cancer, birth defects, and other developmental anomalies.
Based on the insufficient data about chemical sunscreens, at this point it is the safest to recommend sunscreen formulations containing “generally regarded as safe and effective” (GRASE) ingredients, which are titanium dioxide and zinc oxide for people with sensitive skin and for children.
The usage of chemical sunscreens for adults is not considered unsafe.
FDA doesn’t have any data to declare them dangerous.
Regardless of the sunscreen used, we recommend wearing protective UV clothing, hats, and sunglasses, and seeking shade.
