Sunscreen 101

UVB-Screening Sunscreen and Broad-Spectrum Sunscreen

30, 40, 50, 80 SPF... which one is better suited to protect you? Your makeup has SPF, but is it enough to protect you? What does SPF really mean? The information or depth of information given to the consumer really makes it confusing in selecting something that not only feels good, but provides sufficient protection. Therefore, let’s break it down and simplify it:

There are 3 types of radiation we are potentially exposed to: UVA, UVB and UVC, with the majority of UVC being absorbed by the ozone layer and not affecting our skin. UVA radiation penetrates the skin more deeply than UVB and has been known to play a major role in skin aging, wrinkling, and skin cancer. UVA radiation damages specific skin cells called keratinocytes, which are located in the basal layer of the epidermis, where most skin cancers occur. Tanning beds emit primarily UVA rays (up to 12 times stronger than outdoor exposure) so whether in a tanning bed or outdoors, exposure to UVA rays will damage cellular DNA. UVA can be broken down into UVA 1 and UVA 2. UVA 1 has a longer wavelength and penetrates the deepest as compared to UVA 2, which is a short wavelength with more superficial penetration. UVB has superficial penetration of the skin and is the cause for skin reddening and sunburn. Understanding what we are trying to protect ourselves from is only half the battle. How do you select a product that will provide you with adequate protection when most sunscreens have so many ingredients on their labels?

Sunscreens are usually a combination of “chemical absorbers” and “physical filters”. Most UV filters are chemicals, forming a thin, protective film on the skin to absorb the UV radiation before it penetrates into the skin. The physical sunscreens are insoluble particles that reflect UV away from the skin. There are many chemical absorbers with the majority protecting against UVB. The exceptions are Avobenzone which protects against UVA 1, dioxybenzone, ecamsule, meradimate, oxybenzone, and sulisobenzone all provide UVA 2 protection. Physical filters include zinc oxide, and titanium dioxide with zinc oxide providing protection against UVA 1 & 2 and UVB. The term “broad-spectrum” sunscreen indicates coverage for both UVA and UVB. Therefore, rather than looking at the ingredients, seeking out a “broad-spectrum” product with sufficient SPF helps to reduce confusion and frustration when seeking an appropriate sunscreen.

SPF stands for sun protection factor and indicates the amount of protection from UV rays and duration of exposure before burning. For someone wearing a SPF of 15, it would take them 15 times longer in the sun to burn as compared to no use of sunscreen. SPF 15 filters out 93% of UV rays as compared to SPF 30 filtering 97% and SPF 50 filtering 98% of harmful UV rays.

At Lasky, we recommend only broad-spectrum sunscreens from both the SkinCeuticals and Obagi product lines. Both provide sufficient coverage for daily or active outdoor activity. Haven’t tried our sunscreens? Mention reading this article and receive $5 off either one.

Practice Policy Update Regarding COVID-19 View Update Virtual Consultation


Coronavirus (Covid-19) Update

March 23rd, 2020

After serious consideration and in line with the recommendations of our State and Centers for Disease Control (CDC), we are closing the practice until Mid April.

Your health and well-being is our primary concern and we want to do our part to make sure that you are protected.

Effective immediately the following will occur:

  • All procedures and in-person consultations will be suspended until further notice.
  • The office will be available for Retail and PrePaid Packages as well as to answer any and all questions and concerns.
  • Virtual Consultations are available upon request.

We are constantly updating our services and staffing according to the local and national recommendations and will always place your health and well-being as our top priority.

We continue to exercise all the latest recommendations that are handed down by the CDC. These include:

  • Staff have been fully informed and trained to understand the disease process and its modes of transmission.
  • All staff, vendors and ancillary personnel are being asked to refrain from coming to this office if they have any signs or symptoms of a cold or an upper respiratory tract infection.
  • Every patient is also being asked to refrain from coming to the office if they have any symptoms.
  • We are asking our patients about any pertinent travel history.
  • Hand-washing continues to be the most important mode of prevention. Although it is a part of what we constantly do, now we are doing so with heightened vigilance and attention.
  • We have instituted a “no handshakes no hug” policy for now.
  • We have asked all vendors that any unnecessary meetings are canceled until further notice.
  • As we are an accredited medical facility, we are constantly sanitizing all surfaces. We have now vamped that up and our routine, multiple times a day, wiping down all surfaces, desks, door handles, keyboards and restroom facilities. We have assigned a person that does so on a constant basis.

Although Covid-19 is a serious issue, we strongly believe that it will pass and hopefully make our infrastructure and our ability to deal with pandemics in this Country even better than it currently is. We are monitoring this situation on a real-time basis and will not sit back until we know that we have done everything possible to avoid unnecessary exposure.
