Peter Thomas Roth Water Drench SPF Moisturizer Review

Summer is here, which means more sun exposure—and more sunscreen! I always stress about wearing SPF year-round, but in summer your skin really needs it.

The Peter Thomas Roth Water Drench SPF 45 Moisturizer is perfect for the season. It hydrates intensely, protects with a high SPF, and has a silky water-based texture that’s easy to use.

The only downside? The mouthful of a name: Peter Thomas Roth Water Drench Broad Spectrum SPF 45 Hyaluronic Cloud Moisturizer. But hey, at least the product itself is simple and brilliant!

Peter Thomas Roth Water Drench SPF 45 Moisturiser

Peter Thomas Roth Water Drench SPF Moisturizer

The moisturizer has a creamy, thick texture that transforms into a lightweight, clear layer once applied—what they call a “cream-to-liquid” formula. It absorbs beautifully without feeling sticky, and it doesn’t have that strong sunscreen scent, which is always a plus.

Super hydrating, it tackles dry patches while leaving skin plump and nourished. Unlike many SPF face moisturizers, it truly feels like a moisturizer, not just sunscreen. With hyaluronic acid, hydration, and SPF all in one, it simplifies your morning routine while keeping skin protected and cared for.

Wear Test

I tried this moisturizer two ways: alone, with just my eyebrows drawn in (priorities!), and with my full makeup on.

Worn solo, it made my skin look hydrated, smooth, and natural—no white cast at all. I actually love wearing it alone; it feels great and leaves my face looking effortlessly fresh.

Wearing it under makeup took a bit more effort—extra blending was needed to get a seamless look. Once blended, though, my makeup looked glowing and flawless.

Under a light layer of makeup, it’s invisible and very moisturizing. As a moisturizer with SPF, I’d rate it 9/10—it still has a subtle “sunscreen feel,” but is extremely light and comfortable, even when I sweat. For someone always on the go, that’s a big plus!

Is Peter Thomas Roth Water Drench SPF Moisturizer Worth the Price?

At $52/£41, you get a moderate 1.7 fl oz/50 mL of product—not huge for the price, but designer sunscreens are generally pricey.

The bottle is a plastic matte design with a baby blue-to-white gradient and an airless pump. I like that it stands upright, some pumps lose their function when tipped the wrong way, so this is a thoughtful touch.

Ingredients

Peter Thomas Roth Water Drench SPF Moisturizer is a synthetic/chemical-based sunscreen containing the following active ingredients:

Avobenzone (3%) – synthetic sunscreen ingredient against UVA rays
Homosalate (5%) – primarily protects against UVB rays
Octisialte (5%) – chemical sunscreen agent that absorbs sun’s rays and protects against UVB
Octocrylene (10%) – chemical sunscreen agent that absorbs sun’s rays and protects against UVB

Highlighted Key Ingredients:

Broad-Spectrum SPF 45: Peter Thomas Roth claims this to be reef-safe, and that this sunscreen is free of oxybenzone and octinoxate.
30 % Hyaluronic Acid Complex: This helps improve hydration and can attract and retain up to a thousand times its weight in water from moisture in the air.
Pentavitin®: A potent hydrator that provides up to 72 hours of hydration and helps replenish moisture depleted by outdoor heat and sunlight.

Upon further research, some active ingredients aren’t 100% reef-safe, so I’d be cautious wearing it in the ocean.

That said, it wasn’t designed for swimming anyway—more for water-resistant protection when sweating during summer adventures. And yes, sometimes we’re swimming in our own sweat… oh, summer. Sorry for the graphic image, just keepin’ it real!

Other Notable Ingredients:

Glycerin
Argan Oil
Vitamin E (specifically, Tocopheryl Acetate & Tocopherol)
Bisabolol – chamomile extract that minimizes skin irritation
Citric Acid & Sodium Citrate – antioxidants and pH balancers
Hydrolyzed silk – aids in strengthening the skin by increasing its ability to retain water
Other antioxidants (specifically Olive Leaf Extract)
Vitamin C (specifically Ascorbyl Palmitate) – this is readily absorbed by the skin and helps boost collagen production, reduce the appearance of fine lines, and improve complexion

My Thoughts

I love this moisturizer-sunscreen combo! The sunscreen keeps my skin grease-free throughout the day and I can’t recommend it enough!

The packaging is sleek with a clean and fresh feel to it. Pair it with one of the best cleansers for sensitive skin and you’re good to go!

The serum works alone or under makeup. Would I buy it again despite the price? Very likely. I’m picky with sunscreen, and I love how the Peter Thomas Roth Water Drench SPF Moisturizer keeps my skin soft, hydrated, and protected.

All in all, it’s a really great product that will help your skin manage the heat better! Check out some of my other top recommendations for oil-free moisturizers.
