Can you skip sunscreen if your makeup already has SPF? Dermatologists say that’s a terrible idea

By now, we are all well aware that the diligent use of sunscreen is important in keeping our skin looking youthful. After all, sun damage, premature signs of ageing and even skin cancer are just some reasons why year-round SPF application – yes, even when it’s cloudy and raining – in our skincare routine is necessary.

These days we’re also seeing more SPF options that promise to help keep our skin protected – including SPF-infused makeup.

But how effective is SPF-infused makeup? And more importantly, does using them mean we can skip sunscreen? CNA Lifestyle asks the experts to share facts and tips on making the most out of our sun protection.

ARE YOU USING ENOUGH SUNSCREEN DAILY?

According to Dr Eileen Tan, consultant dermatologist at Eileen Tan Skin Clinic & Associates, “a good sunscreen should be one that provides a broad-spectrum coverage against ultraviolet B (UVB) and ultraviolet A (UVA)”.

In short, you should not only look just at a product’s sun protection factor (SPF), but also its protection grade (PA). This is because the SPF measures the length of time the product will protect your skin against UVB rays, while the PA focuses on UVA rays, also known as the rays that age you, explained Dr Tan.

As a good rule of thumb, a sunscreen of at least SPF30 is recommended, and it should applied liberally. If you’re wondering how liberal you should go, Dr Rachel Ho, aesthetic doctor at La Clinic, advised using “2mg/cm2 to get the amount that’s stated on the label”.

That's approximately a quarter of a teaspoon for the face and five teaspoon worth for the entire body, said Dr Tan.

But let’s be real here: How many of us actually follow this rule? Not many.

“In reality, most people do not use this amount because of a lack of awareness and inconvenience,” said Dr Ho.

In fact, Dr Tan shared that she’s seen patients come in with severe sunburn on their upper back and neck regions from missed sunscreen application. Other areas that are often missed include the nose and ears.

SPF MAKEUP: HOW MUCH PROTECTION DOES IT GIVE?  

But before you go skipping your sunscreen application just because your foundation or powder has SPF, here’s what you might want to know.

To get the adequate UV protection from your makeup, said Dr Ho, you’d need to apply the same amount – 2mg/cm2, of makeup every single time. Therein lies the problem. “In practice, this is a very large amount of powder, foundation or blusher that is impractical for daily use,” added Dr Ho.

But that’s not the only reason. Dr Tan also shared that SPF-infused makeup products should not be your sole protection against UV damage as they may not have the necessary ingredients to qualify as a broad-spectrum sunscreen. This could lead to the photoprotection being inadequate and inconsistent if you were to reply solely on SPF makeup for sun protection. 

“Hence the realised amount of UV protection from makeup is lesser than expected,” stated Dr Ho.

USING A SEPARATE SUNSCREEN IS NECESSARY

“In reality, most people use less than the desired amount of SPF makeup, so they don’t get enough UV protection from their makeup,” said Dr Ho. This is why the doctors recommend using a separate sunscreen before your SPF makeup.

Added Dr Ho: “This separate sunscreen layer, when used in the appropriate amount, will be the main layer of UV protection instead of the makeup with SPF”.

Just make sure that you use a broad-spectrum sunscreen with at least SPF30, emphasised Dr Tan. And don’t forget to re-apply regularly if you’re under prolonged sun exposure.

EVERY LITTLE BIT COUNTS

But before you go dismissing the use of SPF makeup, both doctors shared that layering your sunscreen with SPF makeup is a better way to go.

“Using both regular sunscreen and makeup with SPF allows you to get adequate photoprotection and enjoy the benefits of wearing cosmetic products,” said Dr Tan.

In addition, they can also provide additional UV protection for the skin, and more so on areas of the face where sunscreen is often missed, such as the eyelids, shared Dr Ho.

“I would choose makeup with SPF to maximise my UV coverage, especially since many people often use less than adequate sunscreen so the amount of actual UV protection is often less than expected,” Dr Ho added.

And lest you think that you can skip your sunscreen if you layer multiple SPF infused products, from primer to foundation and blusher, think again.

While layering a range of sun protection products will give somewhat better protection, it does not do so in a linear way, explained Dr Ho. That is to say, SPF50 primer, + SPF30 foundation and SPF30 eyeshadow + SPF15 lipstick will not give you SPF125 protection.

Instead, think of layering your SPF products, from sunscreen to makeup, as a way of improving the homogeneity of coverage, especially since we often have insufficient sunscreen application, said Dr Ho.

Ultimately, when it comes to sun protection, it’s definitely something you can never have too much of.
