Introduction
Does every sunscreen you try make your oily skin worse? As someone with oily skin, this has been a constant struggle, especially when the weather is hot or humid, and I don’t want to show up to a date or work occasion with uncomfortably oily skin on full display. The problem is that most Western sunscreen formulations are built for dry skin and aren’t suited for those of us with oily skin.
This article will solve this problem by ranking the best Korean sunscreens specifically for oily skin based on their texture, finish, ingredients, and real-world wearability in brutal heat or humid conditions.
For the full science behind why Korean sunscreen outperforms Western formulations for oily skin, check out my article on the subject here.
What to Look For in a Korean Sunscreen for Oily Skin
There are three crucial criteria for deciding if a sunscreen is ideal for your oily skin.
Texture
You want to avoid anything described as a lotion or creamy. If it looks or sounds heavy, the chances are it’s going to make your oily skin worse and clog your pores.
Instead, find sunscreens with descriptions like watery, gel, fluid, or serum on the packaging. These sunscreens will also feel a lot lighter on your skin when it’s hot, which is a huge benefit for those of us who sweat easily. I, for one, don’t enjoy sweating buckets because thick sunscreen is trapping my body’s heat on a hot summer day.
Finish
Satin is acceptable, but really, you should be opting for sunscreens with labels like matte or natural finish. Anything that adds luminosity will amplify shine on oily skin, which means avoiding sunscreens described as “dewy” or “glow.”
Key Ingredients
I love Niacinamide and Hyaluronic acid because they regulate sebum production at concentrations of 2% and above, while hydrating without adding surface oils. Again, this is super important because you don’t want to overwhelm your oily skin with too much saturation.
Silica is also great because it absorbs excess sebum throughout the day and extends matte finish by two to three hours.
The Best Korean Sunscreens for Oily Skin
Isntree Hyaluronic Acid Watery Sun Gel SPF50+ PA++++
This is my personal favorite, bar none, for my oily skin.
It’s ultra-lightweight with a watery gel texture that absorbs completely on contact with zero residue or sebum activation. If you’re like me and sweat easily while also having oily skin, this is a double win because it’ll help keep you cool on a hot day.
The formula is fragrance-free and alcohol-free, so it doesn't strip skin and trigger compensatory oil production.
It’s super effective at solving the problem of dehydrated oily skin through the molecular weights of hyaluronic acid hydrate.
The finish is a natural matte without any shine-amplification, so your skin looks natural.
Who it’s for
It’s perfect for you if you have acne-prone skin or just regular oily skin.

Best for Oily Skin Under Makeup
Isntree Hyaluronic Acid Natural Sun Cream SPF50+ PA++++
If you want to use foundation and get strong SPF protection without making your skin an oily mess, this one’s for you.
It absorbs cleanly without leaving a silicone-like slip that causes foundation to slide which makes it ideal for use with makeup.
It’ll also help extend makeup wear throughout the day because it creates a smooth even base and doesn't pill when layered under complexion products.
The finish is natural with a slight skin-like luminosity that makes your skin look healthy and vibrant.
Who it's for
Oily skin users who want to wear foundation, BB cream, or tinted moisturiser daily.
Retail price: $24. Available at SeoulSun.com.
Best Budget Option
Isntree Hyaluronic Acid Daily Sun Gel SPF50+ PA++++
This sunscreen features the same Isntree formulation philosophy but at a more accessible price point.
It works well because it consists of a lightweight daily gel that is fragrance-free without any alcohol.
This sunscreen also absorbs quickly and is not as complex a formulation as the Watery Sun Gel. It still delivers the core oily skin benefits.
Who it's for
If you’re on a budget but want a reliable, high-quality Korean sunscreen for your oily skin.
Retail price: $20. Available at SeoulSun.com.
Best Reapplication Option
Round Lab Birch Juice Moisturizing Sun Stick SPF50+ PA++++
Reapplying liquid sunscreen over your makeup is a big problem for those of us with oily skin because it disrupts everything you’ve carefully applied on your face and turns it all into a greasy mess.
The last thing you want is a liquid formula making the breakdown of your base even worse.
Luckily, Korean sunscreens are designed specifically for people who want to reapply makeup later in the day.
The solid balm format glides over makeup without disturbing it and there’s no liquid to activate sebum.
Who it's for
Oily skin types who want to wear makeup but need midday SPF reapplication without ruining their base.

Retail price: $22.
Best for Oily and Acne-Prone Skin
Round Lab Birch Juice Moisturizing Sunscreen SPF50+ PA++++
If you suffer from active breakouts as well as overall oily skin, then you need a sunscreen option that’s a bit more bespoke.
Round Lab’s Birch Juice Moisturizing Sunscreen works great because its birch juice base is inherently soothing and anti-inflammatory and features a non-comedogenic formula.
There are weird essential oils, and the filter is a combination of Tinosorb S and Uvinul A Plu are photostable and non-comedogenic
Who it's for
Oily skin types with active acne and post-breakout skin who need gentle daily protection without aggravating their existing congestion.

How to Apply Korean Sunscreen for Oily Skin
Now that we’ve covered the best sunscreens for oily skin, we need to talk about how to use them most effectively.
Amount
Two finger lengths are enough for most people. Keep in mind that under-applying is the most common mistake oily skin types make when trying to control shine. The problem is that insufficient coverage causes pilling and uneven finish while also exposing your skin to UV damage.
All the sunscreens I’ve recommended allow you to use enough to protect your skin because they’re significantly lighter than Western formulations.
Method
Dot across your face and tap gently instead of rubbing. When you rub, you create friction that activates sebum production, which makes your oily skin problem much worse.
Wait time
Give it at least 60 seconds before you apply makeup. This allows the formula to fully absorb and dramatically reduces pilling under your foundation.
Reapplication
Use a sun stick over your makeup every two to three hours outdoors. Don’t reapply liquid sunscreen over a full face of makeup.
FAQ
Does Korean sunscreen cause breakouts on oily skin?
No. The formulations I’ve recommended here are non-comedogenic and fragrance-free. They’re specifically designed for oily skin types who want to avoid breakouts.
Can I skip moisturiser if I use Korean sunscreen on oily skin?
Yes. The Isntree Watery Sun Gel and Natural Sun Cream both provide sufficient hydration for oily skin as a single morning step. One of the primary reasons oily skin types love Korean SPF is the moisturiser and sunscreen step combined.
Why does my current sunscreen make my skin oilier by midday?
There are two reasons this happens. Either the formula contains heavy emollient ingredients that compound your existing sebum production, or it contains mineral filters like zinc oxide that form an occlusive film trapping sebum underneath. Korean gel sunscreens solve both problems simultaneously.
How do I stop my sunscreen pilling under makeup?
Apply less than you think you need and wait 60 seconds before you apply makeup. Tap and don’t rub when you’re applying the sunscreen.
Is SPF 50 enough for oily skin?
SPF 50 blocks 98% of UVB rays, and every product recommended here carries SPF 50+ with PA++++. This is the highest standard UVA protection rating available. You're fully covered on both UV spectrums.
