Same SPF, seventeen times the price
Two sunscreens carrying comparable regulated claims cost CA$4.16 and CA$71.90 per 100 mL. The claim is regulated; the price is not.

Quick answer
The bottom line
SPF, broad spectrum and water resistance are regulated claims that a product must support with testing, so a cheap sunscreen carrying them has met the same standard as an expensive one. In our dated Canadian sample that meant CA$4.16 per 100 mL against CA$71.90 for comparable claims. Buy on texture and on whether you will apply a full teaspoon to your face every day, because generous use of an SPF 30 beats thin use of an SPF 50. Reapply every two hours outdoors, and after swimming or sweating, whatever you paid.
At a glance
Three things worth remembering
- SPF, broad spectrum and water resistance are regulated claims, so the cheap product met the same testing standard.[3]
Section 01
The gap, in one dated basket
All five carry high SPF claims and broad-spectrum protection. The cheapest is a large body bottle; the most expensive is a small facial fluid. Some of the gap is genuinely paying for a texture designed to sit under makeup, and some of it is paying for a small bottle.[1][3]
| Sunscreen | Pack price | Per 100 mL |
|---|---|---|
| Equate Sport SPF 50+, 237 mL | CA$9.86 | CA$4.16[1] |
| Blue Lizard Sensitive Mineral SPF 50, 89 mL | CA$14.98 | CA$16.83[1] |
| Australian Gold Mineral Tinted Face SPF 50, 74 mL | CA$27.99 | CA$37.82[1] |
| Garnier Ombrelle Ultra Light Advanced SPF 60, 50 mL | CA$22.97 | CA$45.94[1] |
| La Roche-Posay Anthelios Ultra-Fluid SPF 50+, 50 mL | CA$35.95 | CA$71.90[1] |
Section 02
What the number on the bottle actually guarantees
SPF is not a marketing adjective. To print it, a product must be tested to show it delivers that level of protection under a defined application thickness, and broad spectrum and water resistance each have their own required tests. A supermarket own-brand carrying SPF 50 and broad spectrum has passed the same tests as a pharmacy brand carrying the same claims.[3]
What price buys instead is formulation experience: how it feels, whether it leaves a cast on deeper skin tones, whether it stings around the eyes, how it behaves under makeup, and whether the brand invested in cosmetic elegance. Those are real differences, they are just not protection differences.[3][2]
Section 03
The amount you apply outweighs the number
The tested thickness is about 2 milligrams per square centimetre, which works out at roughly a teaspoon for the face and neck and about 30 mL for a whole adult body. Most people apply between a quarter and half of that. Protection falls away steeply below the tested thickness, so the number on the bottle is a ceiling nobody reaches in practice.[5][2]
That is why the price matters in a roundabout way. People ration expensive products. A generously applied SPF 30 delivers more real protection than a thinly applied SPF 50, so the cheaper bottle you use freely can outperform the one you are saving.[5][1]
The one randomised trial that followed daily sunscreen use over years found less measured photoageing in the daily-use group. It tested the habit, not a brand.[4]
Section 04
And SPF 60?
Above SPF 30 the gains are real but small and shrinking. SPF 30 filters roughly 97 percent of the relevant ultraviolet, SPF 50 about 98 percent. SPF 60 sits marginally above that, and the difference between them is far smaller than the difference between applying a full teaspoon and applying half of one.[3][5]
Higher numbers are still worth having if the product is pleasant and affordable, because they leave more margin for the under-application everyone commits. Just do not pay a large premium for the number alone.[2][1]
Section 05
A short way to choose
- Set a floor of SPF 30, broad spectrum. Anything above that is margin rather than a different category.[3][2]
- Buy the largest size of a texture you like, so you never ration it.[1][5]
- Keep a cheap body bottle and, if you want one, a pricier facial fluid. Mixing the two is not inconsistent.[1]
- Reapply every two hours outdoors and after swimming or towelling, whatever the bottle cost.[2][3]
