What does uva mean in sunscreen?

If you’re someone who wants to enjoy a day at the beach without getting turned into a crispy piece of bacon, then sunscreen will likely become your best friend. But as you begin shopping for different sunscreens, one term that may catch your eye is UV protection – more specifically, protection against UVA rays.

So what does this really mean? Fear not fellow beach-goers because we here at Snarky Sun Care are ready to break down all things UVA in sunscreen with our usual sarcasm-infused tone.

What Are UV Rays and How Do They Affect Your Skin?

Before diving deeper into what UVA means in terms of sunscreen, let’s first understand the basics behind ultraviolet (UV) rays and how they can impact that delicate skin of yours, especially during an extended period under direct sunlight.

These energetic waves come from the sun but also artificial sources like tanning beds. There are two types: UVA and UVB.

The Skinny on UVB

UVB rays have higher energy levels than their counterpart (UVA), which makes them better at causing visible damage to your skin’s upper layers rather quickly—they reach only up till skin surface level. Thanks to these qualities, it’s easier for us humans to see their effects through redness or painful burns!

Are You Okay With Just Half Baked Damage?

On the other hand there’s those sneaky “let me get deep inside ya” type spectrum wavelengths – That’s right Ultraviolet-A —U= Ultra; V = Violet; given its relatively longer wavelengths (320-400nm) compared to shorter one (280-320 nm) give them advantage over their partner-in-sun-crime when penetrating beyond superficial epidermis layer etching damaging signs around dermal matrix structures underneath resulting in wrinkle inducing, aging accelerated, and potentially cancerous diseases under regular UV-ray exposure.

The UVA Spectrum

So let’s just say no to the ignoramus in town pretending unprotected fun time at outdoor spots won’t have ugly consequences! And here we go again; as if simple classifications were not enough, UV spectrum got further divided into type A (UVA) able to pass through clouds and ordinary glass effortlessly – oh the joy(!)—but also fortunately-ish interrupted by none other than our ozone layer save for some who live near North or South Pole during certain skin-frying seasons of a year. And there’s Type B (UVB), a bit less damaging as they stay on surface layers but deadly once absorbed too with oxygen radicals formation leading impact on DNA replication process aka what makes you unique.

Tanning? That’s Cute!

And guess what: sometimes tanned bronzy tone is not merely sign of Instagram aesthetic appreciation but warning call from your dermis for premature wrinkle-itis thanks to those darn UVA penetrating deep inside underlying structures where wrinkle fibers get degenerated faster to cause uncharacteristic quick coiling processes returning scars worth continuous regret moments throughout life!

What Is UVA Protection?

Now that you know more about the joys of both types of ultraviolet rays, it should be easy—well relatively—to understand why sunscreen protection against these pesky forces are essential when spending lengthy periods outdoors.

But back to the main question at hand – what does ‘UVA protection’ mean anyway?

Simply put: Any product marked “broad-spectrum” or “UV-A/B” will help guard your pits-inhabiting-meat outer covering shell from both radiation types – although using physical blockers like titanium dioxide, zinc oxide minerals usually cover broader spectra ranges including visible lights effectively compared to synthetic substances creating confusion between safe and harmful formulas sometimes labeled Broad-Spectrum / Full Spectrum monikers in sunscreens created spanning foundation.

Decoding Sunscreen Labels: UVA Star Rating System

For those who are particularly concerned about shielding themselves from the malicious, wrinkle-causing UVA rays, there’s a rating system that you can refer to when shopping for your perfect sunblock (because let’s be real – with hundreds of options out there, it can take hours to pick just one).

Introducing: The UVA star rating system. This particular metric is used to indicate how much protection a sunscreen product offers against UVAs specifically. Most common in UK or some select European Nations; its been replaced officially by PA+ or PPD ratings elsewhere.

5-Star Protection = As Safe As Eating You-Can-Poo Rainbows

A higher number of stars generally implies better protection, so look for the 5-star-labelled bottles like our very own Snarky Tone Up Sunveil Essence! Ahem. Excuse us while we take advantage of this article and do a bit advert push.

Always Be Careful With Numbers Lower Than Five Stars Though!

Despite being united in terms of harmful effects radiation might create upon skin cells between types albeit more long term side effects with Type A such as premature wrinkles & cancers derived through immunosuppression. Higher SPF numbers don’t necessarily correlate perfectly with high UVA defense next time you go sun lotion shopping; ideally covers range above 30 dependent on individual skin type per each person regardless exposure period duration but even least unknown brand names boast fancy-sounding figures it doesn’t mean they have optimal coverage without additional verification checking other than front case labeling slapped onto tube selling rainbowed gel gloop using questionable formulations passing only regulatory recommended minimum levels concentration required by authorities leaving customers skeptical due to harmful trace agent findings at random during tests e.g endocrine disruptor homosalate sometimes leading hormone imbalance or red flags flying over chemical oxybenzone known stoppages in oceanic microorganisms’ DNA production process.

Tips for Choosing the Best Sunscreen

Now that you understand a bit more about UVA rays and the importance of protection from them, here are some tips to keep in mind when shopping for your ideal sunscreen:

Physical vs. Chemical Filters Fight?

While physical filters contain minerals like titanium dioxide or zinc oxide that essentially act as mirrors and reflect UV rays away from skin surfaces, chemical ones absorb radiation instead through electrons transfer reducing it’s impact on underlying tissues making them potentially dangerous since reactions taking part within applied solutions might produce unwanted results with byproducts leading to imbalances shown up later around metabolic pathways within individual bodies!

When it comes down which one is better? That’s debatable — both can provide solid UV-protection. However; For sensitive skin-types people go for gentler mineral alternatives tend benefitting physically oriented offers allow sometime powdery yet lightweight after-feel then guard themselves against synthetic formulations utilizing terms may sound fancy (like “nano”), pursue products free parabens preservatives limit any chances repercussions onset allergic response over time akin irritation period where prolonged usage tends to compound force aggravating cause.

Don’t Be Fooled by Sky High SPF Numbers!

As I mentioned earlier – higher doesn’t necessarily equate to always better. Also past a certain point, even adding SPF factor stops significantly blocking radiations continuously increasing number might pass FDA regulation requirements but not proportional difference prevention wise between suntan lotion using labeled 30 versus those ranging upwards like SPF-50! But Reasonable suggestions hover at SPF-30 dependent upon factors such as pigment tone or activities done during outdoor moments times spent outside environment length exposure kept constant irrespective of choice made on designated level type used each person should highly consider additive features adapted towards particular momentary conditions surrounding areas under heat while inside frame work budget net expenditure covering ingredients preference etcetera before finally agreeing upon any specific personal package plan.

Go for the Gold(PA+) or PPD – Depending on Where You’re Shopping

As mentioned before, The UVA star rating system isn’t exactly standardized worldwide. If you are shopping in Europe or Japan Protecting Policy Disaster (PPD) is used instead of Star Rating often seen in some lotions(Star range may vary from organization to Quality Control). E.g: PA+ means sunscreen has tested well enough compared with other formulas withstand no less then a significant amount UV-A radiation given independent high count ration as guideline determined by measurement method implemented during testing.

Bottom line though? Don’t stress too much over finding the ‘perfect’ sunscreen- more important than anything is just that you use it consistently and generously whenever you know being exposed under sun’s glare whether occasional pool visits or working hours outside keep your skin safe always!
