The short verdict (4.4/5): The Dr.Jart Every Sun Day Sun Milk is a genuinely high-protection, sweat-and-water-proof SPF50+ PA++++ that earns its keep through a Korean summer. It is not the lightest, invisible-finish sunscreen on the shelf, but for outdoor days and humid weather it is one I trust, and the 1+1 sets make it a quiet bargain.
The Every Sun Day Sun Milk is the Dr.Jart+ sunscreen I keep reaching for when I know I will actually be outside, and this review is for anyone weighing it up before they buy. It is a waterproof SPF50+ PA++++ daily sun milk, 30ml per tube, and it usually turns up in those 1+1 gift sets that make Korean sunscreen such good value. Two decades under the Australian sun have taught me the hard way that sun protection is not the place to cut corners.

Why I Bought the Every Sun Day Sun Milk
I picked up the Every Sun Day Sun Milk for the most boring reason possible: I needed a sunscreen that would not slide off my face the moment I started sweating. Living between Sydney and Seoul means I deal with brutal beach UV in one place and sticky, humid summers in the other, and most of the lightweight Korean SPFs I love start to break down once I am genuinely hot. A waterproof formula was the gap in my routine I kept trying to fill.
Dr.Jart+ is also one of the few Korean brands a lot of you already recognise, which made it feel like a sensible one to test and write up properly. The “Waterproof Sun Milk” name is doing exactly what it says: it is positioned as a water-resistant UV protector rather than a glowy makeup-base sunscreen. That distinction matters, because buying the wrong type of SPF for the wrong day is how people end up disappointed.
If you want the wider context before you commit to one tube, my round-up of the best Korean sunscreens at Olive Young puts this kind of waterproof formula next to the lighter daily options, so you can see where it fits. This post zooms right in on the one I keep for my sweatiest, sunniest days.

What You Actually Get: Specs and Price
Here are the facts straight off the packaging, because this is where a lot of online listings get muddled. Each tube is 30ml (1.01 fl oz), rated SPF50+ PA++++, and described as a “Water Resistant UV Protector” — the highest UVB and UVA ratings you will see on a Korean label. The tubes are a clean white with a single orange accent band, and mine came as a 1+1 set in a yellow and orange striped box, so two tubes for the price the shelf advertises as one.
SPF50+ tells you about UVB (the burning rays), while PA++++ is the Korean and Japanese marker for UVA protection (the ageing, deep-damage rays). PA++++ is the top of that scale, so on paper this is about as protective as a daily sunscreen gets. The “waterproof” claim is really water and sweat resistance — no sunscreen is genuinely permanent — which is why reapplication still matters even with this one.
The back of the tube keeps things simple: apply a generous, even amount before sun exposure, distributed by Have&Be in New York, made in Korea. For exact ingredient and usage detail straight from the source, the Dr.Jart+ official site lists the full formula, and I would always check it there if you have reactive skin or specific filter sensitivities. If you are buying from outside Korea, my guide on the best Olive Young products also covers how the gift sets are sold and shipped.
Texture, Finish and How It Wears
The “Sun Milk” name is accurate: this is a milky, fluid lotion rather than a thick cream or a watery essence-type SPF. It spreads easily and sinks in without much fuss, and once it has settled it does the job I bought it for, which is staying put when I sweat. For a waterproof formula, that resilience is the whole point, and on hot days it holds up far better than my lightweight everyday sunscreens.
The finish is where waterproof SPFs usually compromise, though, so here is what I actually found. It is not the invisible, second-skin finish that the trendy “no white cast” sunscreens promise. On my skin it can leave a faint cast and sits a touch more present than an ultra-light daily SPF, especially if I am heavy-handed. That is fairly typical for a high-protection waterproof formula, and giving it a minute to set helps a lot.
Because of that, I treat it as a function-first sunscreen rather than a makeup base. It is the one I reach for on a beach day, a long walk, or a humid afternoon out — not necessarily the one I would layer under a full face of makeup for the office. If you want to work out which finish actually suits your skin type and routine, you can tell the quiz your skin type and discover your best-match Olive Young products before you spend anything.

The Pros and Cons, Honestly
No sunscreen is perfect, and a review without a downside is not worth reading. The biggest reason to buy this one is protection: SPF50+ PA++++ with genuine water and sweat resistance is exactly what you want for an active, outdoor day, and that combination is harder to find than it sounds. The 1+1 value and the recognisable, well-established Dr.Jart+ name both add to the appeal.
The honest trade-offs are the finish and the format. As I said, it is not the lightest or the most invisible SPF, so anyone chasing a completely undetectable base will find lighter options elsewhere. The 30ml tube is also on the small side if you apply the generous amount good protection actually requires, which is part of why the 1+1 set is so welcome. Here is the quick version:
- Pros: top-tier SPF50+ PA++++ protection; genuinely waterproof and sweat-resistant for summer; spreads easily; recognisable brand; great value in 1+1 sets.
- Cons: possible faint white cast; not the lightest, most invisible finish; 30ml runs down quickly with proper application.
One YMYL caveat I always add: a sunscreen protects, it does not treat. If you have a skin condition or react to chemical filters, patch-test first and check the ingredient list rather than relying on any review. The authoritative sun-safety advice from Cancer Council Australia on how much to apply and how often to reapply is worth reading no matter which SPF you choose.
Korea vs Australia: The Value Comparison
This is my one genuine Korea-versus-Australia moment, and it is the reason I stock up on these tubes when I am home. Australia is, fairly, obsessed with sun protection — we grew up with “slip, slop, slap” — and a good waterproof sunscreen here is treated as an essential, priced accordingly. A solid SPF50+ from a Chemist Warehouse or a department-store brand can cost a meaningful amount per tube.
Korean SPF50+ PA++++ formulas like this one, by contrast, regularly turn up in 1+1 deals that effectively halve the per-tube cost. The protection rating on the label is the same top tier, but the value is on another level once you factor in that you are walking out with two tubes. For me, flying back to Sydney with a few of these in the suitcase is simply cheaper than buying comparable waterproof SPF locally.
That said, I will not overstate it: Australian sunscreens are held to a rigorous TGA standard, and there is nothing wrong with buying local. The comparison is about value, not safety — both are highly protective. If you are building a sun-care routine and want broader skin-type guidance, my guide to the best Korean sunscreen for every skin type breaks down which formula suits oily, dry or sensitive skin.

Who It Suits and Who Should Skip It
This is the sunscreen I would recommend to anyone whose main worry is protection holding up under sweat and water. If you hike, swim, walk long distances, or simply live somewhere hot and humid, the waterproof staying power is genuinely useful and the finish is a fair trade for that performance. Normal, combination and even oilier skin should get on with the milky texture well.
I would steer two groups elsewhere. First, anyone chasing a completely invisible, makeup-base finish for everyday desk-to-dinner wear — there are lighter daily SPFs that suit that better, and you should not force a waterproof formula into that job. Second, very dry or reactive skin types should patch-test and check filters first, as with any high-protection chemical sunscreen.
For me, the sweet spot is clear: keep one of these for your active, sunny days and a lighter formula for office wear, and you have most situations covered. The 1+1 set even makes that easy, since you can stash one tube in a beach bag and keep the other at home without feeling wasteful about it.
FAQ
Is the Every Sun Day Sun Milk really waterproof?
It is water and sweat resistant rather than permanently waterproof, which is true of every sunscreen. In practice it holds up far better than my lightweight daily SPFs when I am hot or near water, which is exactly what I bought it for. You should still reapply after swimming, heavy sweating, or every couple of hours of sun exposure, no matter how resistant the formula is.
Does the Every Sun Day Sun Milk leave a white cast?
On my skin it can leave a faint cast, and it sits a little more present than an ultra-light daily sunscreen, especially if you apply it heavily. Giving it a minute to settle helps a lot. It is not marketed as a no-cast, invisible formula, so if a completely undetectable finish is your priority, a lighter daily SPF will suit you better than this waterproof one.
What does SPF50+ PA++++ mean on the Every Sun Day Sun Milk?
SPF50+ refers to UVB protection, the rays that cause sunburn, while PA++++ is the Korean and Japanese rating for UVA protection, the rays linked to ageing and deeper damage. PA++++ is the highest level on that scale, so the Every Sun Day Sun Milk offers about as much broad-spectrum protection as a daily sunscreen can. It is genuinely high protection on paper and in use.
Is the Every Sun Day Sun Milk good value compared to Australian sunscreens?
Generally yes. The protection rating matches what you would expect from a good Australian SPF50+, but Korean sunscreens like this one frequently come in 1+1 sets that roughly halve the per-tube cost. Australian sunscreens meet a strict TGA standard and are perfectly good, so this is a comparison about value rather than safety. If you are visiting Korea, it is worth stocking up.
Can you wear the Every Sun Day Sun Milk under makeup?
You can, but it is not the formula I would choose for that. Because it is a function-first waterproof sunscreen with a slightly heavier finish, it works best on bare or minimal-makeup days and outdoor occasions. For a smooth makeup base I reach for a lighter daily SPF instead, and keep this one for the beach, hikes, and humid afternoons where staying power matters most.
My Thoughts
After living with the Every Sun Day Sun Milk, my honest take is that it is a reliable, high-protection workhorse rather than a glamorous one. It does the single most important job — keeping serious UV off my skin when I am hot and sweaty — better than most of the lighter sunscreens I love for everyday wear. That is worth a lot to someone who has watched too many Australian summers do damage.
I am not going to pretend the finish is its strength, because it is not, and you deserve to know that before you buy. But I knew what I was choosing: protection and resilience over an invisible look. On those terms it delivers, and the 1+1 value seals it. I land at a confident 4.4 out of 5, and I will keep one in my beach bag.
As always, let your own skin be the final reviewer. Mine has talked me out of plenty of prettier-looking tubes that quit the moment I broke a sweat — and this one stayed.
Sorting Out Your Summer SPF?
🛍️ Where to buy: If you want high protection that survives sweat and water, this is my everyday trust — the Dr.Jart Every Sun Day Sun Milk on Olive Young Global. The 1+1 sets make stocking up painless. (affiliate link)
I never rely on a quick rinse after a day in this much SPF — I always follow with a proper cleanser, and mine is the Torriden Dive-In Cleansing Foam, a low-pH melt that lifts sunscreen without stripping. The two live in the same Olive Young basket, which nudges it past the free-shipping mark.
