Everything You Need to Know About SPF (and Why It Matters More Than You Think)

Here is some handy info about SPF, what kinds, why it's important. How to remove it. etc.

If there’s one step in your routine that makes the biggest difference long-term—it’s sunscreen.

Not just for summer.

Not just for the beach.

Every single day.

SPF is your best defense against:

• Premature aging

• Pigmentation

• Loss of firmness

• And long-term skin damage

But with so many options out there, it can get confusing. Let’s break it down simply.

The Different Types of SPF

SPF isn’t just one product—it shows up in multiple steps of your routine:

• Standalone sunscreen (your most important layer)

• Moisturizers with SPF

• Primers with SPF

• Makeup and mineral powders with natural SPF

Here’s the key:

👉 These can layer and support each other👉 But you should never rely solely on SPF in your makeup

Makeup doesn’t get applied in a thick enough layer to give you proper protection.

Also, a quick note: Try to avoid SPF products with added fragrance (parfum)—this can increase sensitivity, especially with sun exposure.

Chemical vs. Physical SPF

There are two main types of sunscreen:

Chemical SPF

• Absorbs UV rays and converts them into heat

• Feels lightweight and invisible on the skin

• Great for everyday wear under makeup

Physical (Mineral) SPF

• Sits on the skin and reflects UV rays

• Typically contains zinc oxide or titanium dioxide

• Ideal for sensitive or reactive skin

Both are effective—it really comes down to what your skin tolerates and what you’ll use consistently.

Why SPF 30–50 Is the Sweet Spot

You’ll see SPF numbers all over the place—but more isn’t always better.

• SPF 30–50 = optimal daily protection

• Below SPF 30 = not enough coverage

• Above SPF 50 = minimal additional benefit

The difference between SPF 50 and SPF 100 is much smaller than people think—so focus on proper application and reapplication, not just a higher number.

How Much SPF Should You Apply?

This is where most people fall short.

For your face:

• Use about ½ teaspoon or the two-finger rule (a line of product on two fingers)

And don’t forget:

• Neck

• Chest

• Ears

Reapplication Matters

SPF isn’t a one-and-done step.

• Reapply every 2 hours when exposed to sunlight

• Reapply after sweating, swimming, or wiping your face

Powders and sprays can help with reapplication over makeup—but again, they’re a top-up, not your base layer.

You Can (and Should) Layer SPF

SPF works beautifully when layered into your routine.

For example:

• Moisturizer with SPF - eg: Prisma Protect, Dynamic Skin Recovery, Power Bright Moisturizer

• SPF primer - eg: Dermalogica Skinperfect Primer SPF30

• Foundation or mineral powder with SPF eg: Glo Pressed Base

This builds more consistent coverage—but your primary protection should always be a proper sunscreen layer underneath.

Why You Need SPF Every Day (Yes, Even in Winter)

A lot of people think SPF is seasonal—it’s not.

• UV rays penetrate through clouds (yes, you can burn on a cloudy day)

• Snow and water reflect UV rays, increasing exposure

• UV damage happens even when you don’t feel the sun

Daily SPF = daily protection, no matter the season.

How to Properly Remove SPF

At the end of the day, removing your sunscreen properly is just as important as applying it.

SPF is designed to stay on the skin—so a basic cleanse often isn’t enough.

We recommend:

• Oil-based cleansers (like Dermalogica precleanse)

• Followed by your regular skin specific cleanser

• Our Favourite option - Dermalogica Oil to Foam Cleanser

This ensures your skin is fully clean, preventing congestion and buildup.

Final Thoughts

SPF is the most powerful anti-aging product you’ll ever use.

It doesn’t just protect your skin—it preserves it.

When used consistently and correctly, it helps maintain:

• Smoother texture

• Even tone

• Firmness and elasticity

It’s not about doing more—it’s about doing the right things, consistently.

And SPF is at the top of that list.
