Wearing sunscreen is not the same as being protected.
6 everyday habits that quietly lower your protection, and a simple fix for each one.
You put on sunscreen this morning. That is a good habit. But are you getting the protection printed on the label?
Often, not quite. And most of the time, the product is not the problem. How we use it is.
Health Canada explains that the SPF number is measured with the recommended amount of sunscreen. Apply less, skip a day or forget to reapply, and the protection on your skin is no longer the protection on the bottle.
This is Chapter 2 of The SPF Conversation. Last week, we looked at why UV matters in every Canadian season. This week, we look at what happens once the sunscreen leaves the bottle.
The short answer
Why does sunscreen fail?
Sunscreen usually falls short because of how it is used, not because of the formula. The most common reasons are applying too little, skipping days, not reapplying during time outdoors, missing areas, avoiding a formula you dislike wearing, and trusting a high SPF number too much. Each one has a simple fix you can start tomorrow morning.
The 6 Reasons at a Glance
Reason 1 · Too little product
The thin layer habit.
Most of us apply sunscreen in a thin layer, especially on the face. We want it to feel lighter, last longer or sit well under makeup. The catch: the SPF on the label is measured with the recommended amount, and research shows most people apply much less than the amount used in testing.
The fix: use about 1 teaspoon of sunscreen for your face and neck, as recommended by Health Canada and the Canadian Dermatology Association. Measure it once with a real teaspoon so you know what the right amount looks like in your palm.
Reason 2 · Skipping days
Sunscreen only when it is sunny.
Many of us reach for sunscreen only when it is sunny, when we plan to be outside for hours, or when we are on vacation. Yet Health Canada recommends sunscreen whenever the UV index is 3 or higher, even when it is cloudy, and the UV index changes from day to day.
The fix: make SPF the final step of your morning skincare routine, every morning. Then you never have to check the forecast to decide. Read Your Morning Skin Ritual.

"Sun protection matters to me. Whether it's cloudy out, whether the sun is shining through the clouds, whether it's a warm, hot summer day, it doesn't really matter. Daily consistency is the key for healthy skin now and in the future."
Sharon Quann · Esthetician, Founder and CEO, Quannessence Skincare
Reason 3 · No reapplication
One layer for a whole day outside.
A morning application is a strong start, but it does not carry you through a full day outside. Sweating, swimming and towelling off all wear it down.
The fix: on a typical indoor day, your morning application is your foundation. When you spend extended time outside, Health Canada recommends reapplying at least every 2 hours, and more often if you are sweating, swimming or towelling off. Keep a sunscreen in your bag for outdoor lunches, long walks and weekend plans. Wearing makeup? An SPF mist or powder over the top can make a midday refresh easier.
Reason 4 · Missed spots
The edges we forget.
Even a generous application can miss the edges. Health Canada reminds us not to forget the ears, the backs of the hands and the scalp, and to protect the lips too. In the treatment room, the hairline, neck and chest are other areas that are easy to skip.
The fix: finish every application with a quick sweep of the hairline, ears, neck and chest, and keep an SPF lip balm close by.
Reason 5 · A formula you avoid
The bottle at the back of the drawer.
Heavy. Greasy. Chalky. Sticky. If a sunscreen feels unpleasant or pills under makeup, it ends up at the back of the drawer, no matter how good the label looks. A sunscreen that stays in the bottle protects no one.
Our founder and esthetician Sharon Quann sees it in the treatment room: "I often saw in the treatment room sunscreen that dried, clogged and irritated the skin. SPF protection shouldn't come at the cost of skin health."
The fix: choose a formula you look forward to wearing. The best sunscreen is the one you will apply generously, every single day.
Reason 6 · Too much faith in the number
SPF is not a time limit.
A high SPF can feel like permission: one application for the whole day, unlimited sun, no need to reapply. Health Canada is clear that using SPF 30 does not mean you can spend 30 times longer in the sun, and that sunscreen is not meant to increase the time you can spend in the sun without burning.
The fix: choose a broad spectrum sunscreen with an SPF of 30 or higher, as Health Canada recommends, then focus on how you use it. SPF 30 filters about 97% of UVB rays and SPF 50 about 98% (MD Anderson Cancer Center), so the gap between them is smaller than most people think. A well applied SPF 30 worn every day can do more for your skin than a higher SPF applied thinly.
From the treatment room
The best sunscreen is the one you actually wear.
Protection is not only in the formula. It is in the teaspoon, the daily habit, the midday refresh and the spots you remember to cover. Our founder and esthetician Sharon Quann explains why it matters so much to her, in her own words.

"As a practicing esthetician, I recommend daily sun protection because it's prevention, not repair. It supports the skin barrier and helps maintain the results we work on in the treatment room. Daily sun protection matters to me because healthy skin is built on consistency."

Common Questions
Common Questions About Sunscreen in Real Life
How much sunscreen should I use on my face?
About 1 teaspoon for your face and neck. Health Canada and the Canadian Dermatology Association both recommend this amount.
How often should I reapply sunscreen?
Health Canada recommends reapplying at least every 2 hours while you are outside, and more often if you are sweating, swimming or towelling off.
Is a higher SPF always better?
Not by as much as the number suggests. SPF 30 filters about 97% of UVB rays and SPF 50 about 98%. How much you apply and how often you reapply matter just as much as the number on the label.
Does sunscreen expire?
Yes. Health Canada advises checking that your sunscreen is not expired, since an expired product may be less effective, and keeping it away from extreme heat, such as a hot car.
