Dr Natalia Spierings has a couple of suggestions in relation to selecting solar cream lotion.

"I suggest a SPF 50," Dr Spierings started, explaining that folks, typically, don't placed on sufficient sunscreen as it's.

"What is more important than SPF level is that enough volume is applied," she pressured.

"So 2.5 ml for the entire face/neck/ears is the usual standard, which is a lot."

While Dr Spierings prefers mineral sunblocks manufactured from zinc oxide or titanium oxide, they are often "a bit chalky and leave a white caste".

Aside from them not being pleasing aesthetically, these types of sunblocks "don't photodegrade in the sun like chemical sunscreens".

Dr Spierings famous, nonetheless, that "chemical sunscreens are perfectly adequate, but do need to be reapplied every two to three hours with constant sun exposure".

Mineral sunscreens, however, "only need to be reapplied after swimming, towelling off or rubbing it off".

When taking a look at SPF safety on sunscreen, Dr Spierings mentioned: "SFP refers to the level of UVB protection. UVB [rays] are thought of as the ‘burning’ rays.

"UVA rays from the solar are those that trigger the DNA harm and you'll decide how good a sunscreen is at doing that by wanting on the UVA star ranking."

Dr Spierings elaborated: "The ranking goes from one to 5, with 5 being the simplest."

What about moisturisers or foundations that contain SPF?

These are not effective forms of sun protection, said Dr Spierings, as "you virtually definitely received’t be making use of sufficient to succeed in the said SPF".

Dr Spierings added: "Ideally you'll apply 1 / 4 to half a teaspoon of sunscreen to your face first, then moisturiser if required after which make-up and so on if you want.

"Don’t rely on moisturiser or foundation to provide adequate sun protection."

For those that endure from eczema or psoriasis, Dr Spierings mentioned mineral sunscreens are "generally considered less irritating than chemical [sunscreens]".

While sunscreen could look like a very powerful think about defending your pores and skin from the solar, it isn't.

"The most important thing to do to protect your skin from the sun is to physically block your skin from sun exposure with clothing, hats, etc."
