ON THE SHELF - SPF'S I LOVE
Updated: Mar 26
I thought I would round up my favourite sunscreens that will keep your skin safe from the sun without leaving you sticky, spotty, tacky or smearing unsightly white paste across your face.
But first here is a glossary of SPF terms to help you...
SPF
This is your Sun Protection Factor (SPF) and tells you how well a sunscreen will protect your skin from burning.
About SPF numbers
This number tells you how much UVB light (the burning rays) a sunscreen can filter out.
Here's what the science tells us about how much UVB light different SPF's can filter out:
SPF 15: 93% of the sun's UVB rays
SPF 30: 97% of the sun's UVB rays
It’s important to know that no sunscreen can filter out 100% of the sun’s UVB rays. That’s why it’s important to also seek shade and wear sun-protective clothing — such as a lightweight and long-sleeved shirt, pants, a wide-brimmed hat, and sunglasses with UV protection.
How Often Should I reapply?
Sun rays will break down the sunscreen and will become ineffective after some time.
If outdoors you should reapply:
Every 2 hours
After toweling off
When sweating*
After being in water*
*When using water resistant sunscreen, you'll need to reapply every 40 to 80 minutes.
Chemical sunscreen vs Physical sunscreen?
A chemical sunscreen: Protects you by absorbing the sun’s rays. May contain one or more of many possible active ingredients, including oxybenzone or avobenzene.
A physical sunscreen: Protects you by deflecting the sun’s rays. Contains the active ingredients titanium dioxide and/or zinc oxide.
Some sunscreens use both types of active ingredients, so they contain one or more active ingredient found in physical sunscreen and chemical sunscreen.
Broad-spectrum
A sunscreen that offers protection from both UVB rays, which burn skin, and UVA rays, which cause damage like collagen breakdown.
PA+ (++++)
This determines how much UVA protection a sunscreen provides. This isn’t to be confused with SPF which indicated UVB.
This is what each PA rating means:
PA+ = Some UVA protection.
PA++ = Moderate UVA protection.
PA+++ = High UVA protection.
PA++++ = Extremely High UVA protection.
UVA penetrates deep into the skin and causes collagen breakdown. This is why it is so important to have both UVA + UVB coverage.
There is questions over how useful PA+ is as it is measured against how quickly your skin tans or darkens from the sun. As skin will change colour at different rates depending on the purpose it is considered an inconsistent rating.
Ocean Friendly or Reef Safe
A sunscreen doesn't contain any of these five ingredients: oxybenzone, octinoxate, octocrylene, 4-methylbenzylidene, and butyl-paraben.
Small studies suggest that these ingredients can affect coral's ability to reproduce by harming or killing coral larvae and even reduce its life span and immunity.
SHEER PHYSICAL PROTECTION
Mineral Sunscreen Broad Spectrum SPF 50
Matte-finish tinted sunscreen PA++++
Ideal for all skin types but especially for acneic, sensitive and darker skin tones.
This mattifying fluid sunscreen is non-greasy and absorbs quickly. Formulated with a slight tint which helps the product to blend in with your skin tone, preventing any annoying white smears. I often find that sunscreens break me out but with Neostrata it is non-comedogenic and doesn't cause pimples or acne meaning I want to apply it on to my skin.
It has a broad spectrum coverage defending the skin against UVA and UVB rays, which helps prevent premature ageing as well as sunburn.
The formula combines potent antioxidants (green tea, lactobionic acid, vitamin E) which work to neutralize free radicals which we get when in the sun and a Polyhydroxy Acid (PHA) complex to protect and strengthen skin's moisture barrier against environmental aggressors. Formulated exclusively with mineral sunscreens: Zinc Oxide and Titanium Dioxide.
