Understanding Your SPF

You know you need it if you want to protect your skin from wrinkling, skin cancer and other unwanted complications, but how much do you really know about your sunscreen? There are numerous brands and types of sunscreen to choose from, and it can be difficult to know which one is best for you. Understanding how to read the label on your sunscreen can ensure your skin has the protection it should from sun damage.

UVA or UVB Protection?
Although the specific kinds of damage that each causes has been debated over the years, it is best to choose a sunscreen that protects your skin from both UVA and UVB rays. Ultraviolet A (long-wave) and Ultraviolet B (shortwave) rays can both penetrate the atmosphere and play a significant role in conditions such as premature skin aging, eye damage, skin cancers and lowered immune system.

Sunblock vs. Sunscreen
Sunblocks refer to products that physically block against UVA and UVB rays. These are those with zinc oxide and titanium dioxide, and they are considered your best defense. Chemical sunscreens, such as oxybenzone and PABA, are colorless and use ingredients to filter and reduce UV rays. A chemical sunscreen will break down under sun exposure and will need to be reapplied more frequently.
Which SPF?
The SPF stands for sun protection factor. This number ranges from 2 to 65 and refers to the product’s ability to block out the harmful rays of the sun. SPF 30 means that an average person’s skin will take 30 times longer before it is damaged than if the person was not wearing sunscreen. Most dermatologists recommend that you use sunscreen of at least SPF 15 or greater every day, year-round. If you intend to be in the sun more than 20-30 minutes a day, you should wear sunscreen of at least SPF 30.
Not all sunscreens are created equal, and not all skin types react to sun the same way. What works for your friend may not work for you. Therefore, it is always best to ask your dermatologist which sunscreen product is most effective for your specific skin type. Protecting your skin from the sun should never be taken lightly. Although you may not see the damage in your early years, you will likely regret your tanning days as you get older. Just one incident of blistering sunburn as a child can increase your risk for skin cancer!

The doctors and PA’s are great and very knowledgeable. I never have to wait to long and the office staff is always very nice. I also take my son there and they are great with him as well. I would highly recommend Olansky Dermatology.

Kristen R.

Olansky Dermatology is wonderful! Our whole family goes. My daughter has had terrible eczema through the years and both my kids had mollescum too. They always make things better and spend time explaining whats wrong and how to fix it.

Mike D.

I recently had a couple appointments at Olanksy Dermatology and was seen by Julia Lee. Julie was excellent and quickly took care of the issue I was having with my skin. I would highly recommend Olansky Dermatology and especially Julia Lee to anyone in need of a dermatologist.

Very kind and understanding people. Dr. Bellamy and her nurse took the time to listen to all my concerns and never made me feel rushed.

Kishan P.

I was actually running a bit late, but they were very friendly and knowledgeable about what was going on with my skin. And also very timely.I will definitely stick with them!

Khol S.

Very professional and pleasant staff. When I arrived at my appointment this afternoon I was informed that my doctor called out sick and they tried calling to let me know but I just recently changed my number so they were unable to reach me. The receptionist was so sweet and helpful. Instead of leaving and making a new appointment they fit me in without an issue and without any waiting.

Susan H.

Dr. Ilyas was highly recommended to me so I decided to change dermatologists. I am so glad as I am pleased with his expertise and his highly professional manner. I am also delighted with Emily Raville, Aesthetician. She does a wonderful job and I am recommending her to my friends as well. I am completely satisfied – can’t get any better than that!

Lindsay S.

I have been going to Olansky Dematology for many years now, whether for a specific problem, or just for a really great deep facial, and I wouldn’t consider going anywhere else. Every single staff member is knowledgeable and professional. The customer service I receive every visit leaves a positive and lasting impression. I always feel comfortable and at ease while I am there. Great staff!

Janet R.

I seem to live at this place! Whether it’s for an appointment with a doctor or for an aesthetic treatment, I am there frequently. I cannot say enough good things. Efficient, friendly, the best doctors, and a new aesthetic center with the latest in procedures and products to keep us looking almost as young as we feel. It’s always fun to see Emily and she knows just what to recommend.
