If you’ve been following me for a while, you probably know how picky I am when it comes to sunscreens. Most don’t last more than a month in my routine. My standards? No eye stinging, no pilling, must layer under makeup flawlessly, and absolutely no pore clogging. So, when The Ordinary SPF 45 Serum launched, I had to try it. And now I’m sharing my honest, in-depth, and 100% practical review. Spoiler: I was impressed—but not without a few caveats.
The Ordinary SPF 45 Serum Review: Why It Caught My Eye Instantly
I’m always on the hunt for that one sunscreen that checks all the boxes. The Ordinary UV Filters SPF 45 Serum stood out right away because of its mineral-based formula that combines non-nano zinc oxide and titanium dioxide, plus hydrating, soothing, and antioxidant-rich ingredients. It felt like The Ordinary was really listening to what we want from a modern SPF.
Key Ingredients Breakdown:
- Zinc Oxide & Titanium Dioxide: Offer broad-spectrum protection from UVA and UVB rays. These are physical filters, which are generally less irritating and safer for sensitive skin.
- Vitamin E & Eukarion: These antioxidants help fight oxidative stress and environmental damage.
- Peptides & Bio-saccharides: A calming combo that works to support the skin barrier.
- Squalane & Glycerin: Moisturizing agents that provide hydration without the heavy, greasy feeling.
Texture, Scent & Skin Feel: What It’s Like to Actually Use It
Texture:
Right out of the bottle, this sunscreen feels like a fluid serum. It’s easy to spread, blends well, and doesn’t feel sticky. Compared to other mineral sunscreens, the texture is a dream—light, smooth, and surprisingly elegant.
Finish:
It dries down to a semi-matte finish that still gives your skin a bit of a healthy glow. On my medium olive skin tone (MAC NC30), there’s no chalky residue or awkward blending time. That said, if you have deeper skin tones, a subtle white cast might be noticeable, especially if you apply a thick layer.
Scent:
There’s no added fragrance, and no weird SPF smell either. Just a clean, neutral scent that disappears quickly after application.
Who Should Try The Ordinary UV Filters SPF 45 Serum?
This is not your typical drugstore sunscreen, and that’s a good thing. It’s packed with skincare-level ingredients that make it worth a look.
Perfect For:
- Sensitive Skin: Free from common irritants like alcohol, essential oils, and added fragrance.
- Pregnancy-Safe Skincare: Mineral filters are usually recommended during pregnancy and breastfeeding.
- Rosacea-Prone Skin: It soothes rather than stings, thanks to its gentle formulation.
Might Not Be Ideal For:
- Very Deep Skin Tones: If you dislike any hint of a white cast, this might not be your favorite.
- Those Wanting a Matte Finish: It’s not dewy, but it’s not oil-controlling either.
How I Integrated It into My Morning Skincare Routine
Let me walk you through my exact morning routine to show you how this fits in. It’s all about layering and synergy.
My Morning Routine:
- Gel Cleanser
- Hydrating Toner
- Hyaluronic Acid Serum
- Lightweight Moisturizer
- The Ordinary UV Filters SPF 45 Serum
I wait a minute or two before applying makeup. The result? No pilling, no cakiness, and everything stays in place.
Makeup Compatibility: Can It Handle Foundation?
This is a major factor for me. I tested this SPF under multiple foundations:
- Ilia Super Serum Skin Tint
- Estée Lauder Double Wear
- L’Oréal True Match Lumi
In every case, the SPF acted like a smooth primer, creating a soft base without disrupting the finish. No patchiness, no oxidation, and no slipping by the end of the day.

Reapplying SPF Throughout the Day: Can It Be Done?
We all know we’re supposed to reapply sunscreen every few hours, but doing that over makeup is the real challenge. I tried two methods:
- Tapping the serum gently over makeup: Worked surprisingly well. It didn’t lift my foundation or make things greasy.
- Using a cushion puff or beauty blender: Even better for touch-ups without disturbing makeup.
Still, for practicality, I suggest carrying a powder or mist SPF for reapplication when you’re out and about.
Real-Life Wear Test: How It Held Up in Different Conditions
I wore this SPF during multiple types of days:
- Hot & Humid Weather: It held up nicely with a bit of blotting.
- Dry Indoor Air: Skin stayed hydrated without needing extra moisturizer.
- Outdoor Walks: No irritation, no burning, no redness.
This isn’t a sweat-proof sunscreen, so if you’re doing intense workouts or swimming, you’ll need something water-resistant. But for daily wear? It performs like a champ.
