A dermatologist isn’t one of the specialists you necessarily think you’ll need during and after cancer treatment.  However, advances in treatments have made skin-related conditions very common.

We’ve asked one of Canada’s top Onco-Dermatologists, Dr. Maxwell Sauder, for the  latest supportive information to help patients reduce and relieve the side effects they are experiencing.

Here are his recommendations for caring for your skin, scalp and nails during treatment and beyond.

Dr. Sauder is a board-certified dermatologist in Canada (FRCPC) and the United States (DABD) with additional fellowship training in cutaneous oncology. He is a former faculty member of Harvard Medical School where he focused on skin toxicities of anti-cancer treatments (STATs). He is currently an onco-dermatologist at Princess Margaret Cancer Centre where he assists in the management of complex cutaneous malignancies and STATs. He also practices at Toronto Dermatology Centre where he is the director of the Pigmented Lesion Clinic that uses cutting edge artificial intelligence technology to identify and manage skin cancers or precancerous lesions at the earliest possible stage.

Suncare During Radiation Treatment

As a general rule, you don’t want any sun exposure on a treatment site while receiving radiation treatment. Always check with your radiation oncologist before using sunscreen if you are undergoing radiation. Your doctor may not want you to put sunscreen because the skin is prone to injury.

General Sun Protection Tips During Cancer Treatment

Use a sunscreen that is specially formulated for your face that delivers both UVA and UVB protection in a broad spectrum SPF 30 or higher.

Apply sun protection daily and liberally – a dollop about the size of a golf ball – to all exposed skin, such as the lips, ears, scalp, sides and back of neck, and exposed chest.

Get in the habit of applying sun protection every morning, about 20 to 30 minutes before going outside, and reapply often – about every two hours.

Remember that you’re still exposed to UVA/UVB rays even in the shade.

Stay inside during the intense-sun hours of 11 a.m. to 4 p.m. Though remember: If you’re indoors, windows offer no protection against UVA rays.

Don’t forget to wear a hat – preferably one with a wide brim of about three inches.

Remember:

Put your sunscreen under your makeup. (Apply sunscreen first). SPF numbers aren’t cumulative. If your moisturizer and foundation both have an SPF of 15, it doesn’t mean that you’ll have a protection of SPF 30.

UVA and UVB rays:

UVA

UVA is long-range ultraviolet radiation that has the ability to penetrate deep into the skin, causing immediate tanning, premature skin ageing and can play a role in the development of certain skin cancers. UVA is not readily absorbed by the ozone layer – about 95% gets through.

UVB

UVB is short-wave ultraviolet radiation that can penetrate the epidermis and is responsible for delayed tanning, sunburns and most skin cancers.

A large portion of UVB is absorbed by the earth’s ozone layer – only 5% reaches the planet’s surface.

Sun Care and Safety during Cancer Treatment

Radiation and chemotherapy treatments, as well as some medications, can increase your susceptibility to sunburn and skin damage. Sun care is especially important when you are undergoing treatment.

Receiving Radiation? 

As a general rule, no sun exposure is a good idea when you’re receiving radiation treatment if the site of the treatment is exposed skin. Your doctor may not want you to put sunscreen or any cream on while you’re receiving radiation treatment as the skin is prone to injury at that time.

Important!

Always check with your radiation oncologist before applying sunscreen and exposing a treatment area to the sun.

Sun Safety During Treatment

Apply sun protection daily and liberally – a dollop about the size of a golf ball – to all exposed skin, such as the lips, ears, scalp, sides, and back of neck

Get in the habit of applying sun protection every morning, about 20 to 30 minutes before going outside, and reapply often – about every two hours

Remember that you’re still exposed to UVA/UVB rays even in shady areas. If you’re indoors, windows do not protect against UVA rays

Stay inside during the intense-sun hours of 11 a.m. to 4 p.m. Wear clothing especially formulated with SPF when you have to go out into strong sun.

Don’t forget to wear a hat…

preferably one with a wide brim of about three inches.

Don’t forget your eyes…

they need protection too. Wear sunglasses with UVA/UVB protection.

Treatment over? Here are some product options…

Plump it up

Let’s talk about Hyaluronic Acid

If you've noticed your skin getting drier as you age, or that's just your skin type, one active ingredient to be on the lookout for is hyaluronic acid, especially in a serum.

The molecule, famous for holding 1000 times its weight in water, helps bring moisture to the surface of your skin. In the right formulation, it can produce immediate plumping effects, leaving skin looking dewy.

But for folks with very dry skin or who live in a dry climate, Dr. Julia Carroll, dermatologist and co-owner of Compass Medical, suggests layering moisturizer on top of your hyaluronic acid serum to seal it in and provide a barrier to moisture loss.

Brighten & Protect

Vitamin C is a workhorse ingredient and antioxidant

Helps improve uneven skin tone, fine lines, dullness and rough texture

Helps prevent oxidative stress caused by free radicals

"Antioxidant molecules help to neutralize these harmful atoms by giving up some of their own electrons. Think of it as nature’s “off” switch." – Dr. Vincent Richer, Medical & Cosmetic Dermatologist at Pacific Derm

Serum or Moisturizer

A serum and moisturizer combo can enhance your skincare routine —but what is the difference?

Serums are formulated to penetrate deeply into the skin to deliver targeted active ingredients. [This means they’re thinner and lighter to their creamier counterparts and also a more powerful delivery method]. Moisturizers help to reinforce the surface of the skin and work to increase hydration." – Dr. Arisa Ortiz, Harvard-trained & Board Certified Dermatologist

Layering Skincare Products

Whether you are a product minimalist or maximalist, the order you apply your skincare matters—both for your skin’s health and the products’ efficacy.

For the less-is-more folks, keep it simple: cleanser, moisturizer, sunscreen.

If your routine is more robust: cleanser, toner, serum(s), eye cream, moisturizer, face oil, sunscreen.
