How to select sunscreen and how much to apply

We all know sunscreen is a health and beauty must. Afterall, 90% of aging is attributable to the sun’s UV rays. But, some of us - not looking at you! - still aren’t wearing it on a daily basis. You don’t need to be at the beach to necessitate sunscreen… the sun’s rays are out every day, everywhere. Here's how to select the best sunscreen for your skin and how much to apply to ensure full protection.


London-based Facial Aesthetics & Ocuplastic Surgeon, Dr Maryam Zamani explains: “Sunscreen is an essential protection from the harmful UV radiation that contributes to DNA damage. This can manifest itself in the form of skin cancers and photo ageing signs, such as pigmentation, lines and wrinkles. I prefer SPF that have double filters: physical and chemical SPF to ensure a more complete coverage.”


Although there is a virtual sea of sunscreens out there, you just need to be on the lookout for two things:

1. A minimum of SPF 30

The SPF number refers to the length of time you can stay in the sun without getting burned when wearing the sunscreen versus when not wearing it.

2. Broad-spectrum protection

To be classified as a broad-spectrum sunscreen, the formula must absorb or reflect at least 90% of the UV-A and UV-B rays. So, it needs chemical filters which absorb UV radiation before they penetrate the skin and/or mineral (physical) filters which reflect UV radiation away from the skin.


Applying a sunscreen once a day to your face isn’t enough. And applying less than 1/4 teaspoon of sunscreen to your face is also not enough. Enter… the new sunscreen trend... Double SPF!

Just as double cleansing involves washing your face with two different cleansers – an oil-based one, followed by a water-based one, double SPF involves using two times the same sunscreen or, even better, different sunscreens with different formulations.

Mix a lightweight sunscreen into your moisturizer.

Then liberally apply second layer of sunscreen after the moisturizer.

Add a few drops of the SPF into your moisturizer by mixing them together in the palm of the hand prior to application.

We recommend Bi-Phase Veil SPF 45 PA+++. This feather-light formula offers advanced mineral and probiotic UVA/UVB protection.

Some of us – again not looking at you! – neglect to apply an opthalmologically-tested SPF to the eye zone area. Don’t make that mistake.

New York City-based optometrist, Dr. Jennifer Tsai explains: "The skin around our eyes is one of the most delicate areas. It is most susceptible to UV damage, pigmentation, and wrinkles, which is why it's important to apply SPF daily. I recommend a minimum of SPF 50. "
