Everything You Need To Know About SPF: From The Facts, To The Myths

Spring is officially doing its thing, and while your wardrobe is getting a lighter refresh, your skincare routine needs to stay consistent where it counts. One non-negotiable? SPF. Whether you’re heading into the office or catching that first bit of sunshine with an iced coffee in hand, daily sunscreen is still the step that makes the difference.

Consider this your go-to guide to SPF awareness, from breaking down the biggest SPF myths to getting your early spring sun protection routine right. Because glowing skin is great… but protected, healthy skin is even better.

Why SPF Matters All Year Round… Not Just In Spring And Summer 

Just because it’s not full summer sunshine, it doesn’t mean you can skip the SPF. Early spring light can feel soft and low-key, but UV rays are still very much present.

UVA rays (the ones linked to premature ageing) don’t rely on heat or brightness. They pass through clouds and even glass, quietly impacting the skin throughout the day. In fact, a high percentage (99% to be exact) of UV still reaches your skin when it looks overcast, which is why SPF for cloudy days is just as important as when the sun is fully out.

Dermatologists suggest broad-spectrum SPF as one of the most effective ways to protect against photoageing, uneven tone and long-term skin damage. It’s the step that supports everything else in your routine.

Understanding The Differences Between Mineral And Chemical SPFs 

Choosing an SPF is a bit like choosing your base. It can take a bit of trial and error, but it’s all about what works best for your skin and how you like your finish to feel.

Mineral SPFs

Think of these as your skin’s built-in shield. Formulated with ingredients like Zinc Oxide or Titanium Dioxide, they sit on the surface and help deflect UV rays away from the skin. They’re often a go-to for sensitive skin types, or anyone leaning into clean beauty routines. You’ll usually find them in soothing, minimal formulas that feel super gentle on the skin. 

Chemical SPFs 

These formulas work a little differently. Instead of sitting on top, they absorb UV rays and convert them into heat, which is then released from the skin. They’re typically lightweight, invisible and easy to layer, making them ideal for everyday wear and perfect under makeup. If you want something that blends seamlessly into your routine, this is where to look.

Your Common SPF Myths, Debunked 

Let’s clear a few things up. SPF can feel simple, but there’s a lot of misinformation out there. Here’s what actually matters if you want your skin to stay protected and glowing.

Myth 1: “You only need SPF on sunny days.”

Not quite. UVA rays are present all year round and can pass through clouds, so your skin is still exposed even on grey days. Daily SPF is non-negotiable, whatever the weather’s doing.

Myth 2: “SPF in makeup is enough.”

It helps, but it’s not enough on its own. Most people don’t apply makeup in thick enough layers to get the full protection listed on the label. Always use a dedicated sunscreen underneath for proper coverage.

Myth 3: “Higher SPF = fewer top-ups.”

We wish. A higher SPF gives more protection, but it doesn’t make it last longer. Reapplying every couple of hours is still key, especially if you’re outdoors or on the move.

Myth 4: “Darker skin tones don’t need SPF.”

Not true. While melanin offers some natural protection, it doesn’t fully shield against UV damage. Concerns like hyperpigmentation and uneven tone can still be triggered without SPF.

Myth 5: “SPF number = hours of protection.”

This one gets confused a lot. SPF refers to how well a product protects against UVB rays, not how long it lasts. That’s why consistent reapplication is just as important as the SPF number itself.  

How To Actually Wear SPF Daily 

From how much to when, here are our tried and tested top tips.

How Much To Apply

When it comes to SPF, more is MORE. Aim for around a quarter of a teaspoon to cover your whole face and get the actual protection promised. If your neck or décolletage is on show, don’t skip those either… they need coverage just as much.

Why Layering Is Key

SPF should sit comfortably in your routine, right after moisturiser and just before makeup. This helps it form an even layer across the skin without being diluted. Makeup with SPF is a nice extra, but it shouldn’t replace your main sunscreen step. Pair it with glow-boosting and hydrating essentials to keep skin looking fresh underneath.

Don’t Forget To Reapply

SPF isn’t a one-and-done step. Reapply every two hours to keep protection consistent, especially if you’re outside, travelling, or touching your face lots throughout the day. If you’re out and about, SPF mists and sticks make top-ups quick and easy without messing with your makeup.

Areas We Often Forget

It’s not just your face that needs attention. Ears, neck, lips and hands are often missed but are just as exposed. Even your feet can catch the sun once the weather warms up, so it’s worth keeping them in mind too. 

Choosing The Right SPF: An Expert Guide

Here are a few things we’d recommend:  

Broad-Spectrum Is Non-Negotiable 

The first thing to check? Broad-spectrum protection. This means your SPF is covering both UVA (the ones linked to ageing) and UVB (the ones responsible for burning). You want both, every single day, no exceptions.

Go For At Least SPF 30+ Everyday 

For daily wear, SPF 30 (or higher) is the sweet spot. It gives solid protection without feeling heavy, which makes it easier to wear consistently. Early spring sun can be unpredictable, so having that level of coverage built into your routine is key.

Choose By Skin Type

The right texture makes all the difference. Here’s some helpful pointers: 

Sensitive skin: Mineral SPFs with calming ingredients can feel more comfortable

Oily skin: Lightweight gels or fluid formulas help keep things fresh

Dry skin: Creamier textures or moisturiser + SPF hybrids add extra hydration

So, Does SPF Cause Breakouts?

Good news… SPF isn’t the problem. Breakouts are usually linked to heavier textures, pore-clogging ingredients, or not removing your sunscreen properly at the end of the day.

The fix is all about choosing the right formula for your skin. Lightweight gels, fluid sunscreens and non-comedogenic options are designed to sit comfortably without overwhelming the skin. Many of today’s SPFs are also formulated with balancing ingredients like Niacinamide to help keep things calm and clear.

Don’t forget that taking it off properly is just as important. A thorough cleanse, especially a double cleanse in the evening, helps remove buildup. SPF can absolutely work for breakout-prone skin… it’s just about finding your match.

A Step-by-Step Spring Routine 

Cleanser: Always start with a clean canvas. Removing overnight buildup helps everything that follows sit better on the skin.

Serum: This is where you can add targeted benefits. Vitamin C is a great daytime choice, helping to boost brightness while working alongside your SPF.

Moisturiser: Lock in hydration before you layer on protection. Well-prepped skin helps SPF apply more evenly.

SPF 30+ (Broad-Spectrum): This is the step that brings it all together. Apply generously (a quarter of a teaspoon remember) and make sure you’re covering all exposed areas.

Oh and don’t forget a midday SPF refresh to keep your protection going throughout the day. Definitely invest in a spray or stick to make reapplying quick, easy and makeup-friendly.
