COSRX Ultra-Light Invisible Sunscreen review: the oily-skin pick over aloe and stick
Updated October 22, 2026
The COSRX Ultra-Light Invisible Sunscreen is the one to buy if you have oily or combination skin and want a plain daily sunscreen without a white cast: it uses chemical filters only, and its ingredient list includes no fragrance and no drying alcohol. Add the Airy-Light Invisible Sun Stick if you want a pocket-size sunscreen for reapplying away from home, choose the Aloe 54.2 tone-up only if you want a brightening tint, and choose the Aloe Soothing Sun Cream only if your skin runs dry and fragrance doesn't bother you.
All four cost between $10.99 and $15.99 at Sleepy Hello, so the choice comes down to filters, finish and format rather than budget. The cream-or-stick question has a short answer too: wear a cream in the morning and use the stick for top-ups.
This is a researched comparison of current Sleepy Hello product information and COSRX's own published ingredient lists, checked October 2026. We haven't worn or tested these sunscreens; texture and finish descriptions are COSRX's, and the buying advice comes from comparing formulas, directions, sizes and prices.
What you're buying with the Ultra-Light Invisible Sunscreen
COSRX Ultra-Light Invisible Sunscreen, 50 ml is a facial sunscreen in a 50 ml (1.69 fl oz) tube. The tube is labeled SPF50+ PA++++ and names witch hazel, aloe and hyaluronic acid on the front. It costs $10.99 at Sleepy Hello, checked October 2026, which works out to about 22 cents per ml.
COSRX describes it as sheer and fast-absorbing, with a transparent finish across skin tones and a hydrated, non-greasy feel. COSRX publishes the full ingredient list on its official Korean store, where the same 50 ml tube is sold as Ultra-Light Invisible Sunserum SPF50+ PA++++. The first ten ingredients are:
Aloe barbadensis leaf water, the first ingredient (it comes ahead of plain water)
Diethylhexyl succinate, a light emollient that gives the formula slip
Propanediol, a humectant that draws water into the top layer of skin
Water
Drometrizole trisiloxane, a UV filter
Ethylhexyl triazone, a UV filter
Niacinamide, a form of vitamin B3
Diethylamino hydroxybenzoyl hexyl benzoate, a UV filter
Terephthalylidene dicamphor sulfonic acid, a UV filter
1,2-hexanediol, a humectant that also supports the preservative system
Further down come witch hazel leaf water, adenosine, tocopherol (vitamin E), sodium hyaluronate (a salt form of hyaluronic acid) and allantoin. COSRX doesn't publish the percentage of niacinamide or of any other ingredient. In Korea the product is registered as a functional cosmetic for UV protection, brightening and wrinkle care, which lines up with the niacinamide and adenosine in the formula.
The directions are short: apply evenly to clean, dry skin before sun exposure, wear it alone or under makeup, and reapply every two hours and after swimming, sweating or towel-drying.
Is the COSRX Ultra-Light Invisible Sunscreen chemical or mineral?
It's a chemical sunscreen. All four of its UV filters are organic filters, the kind usually called chemical, and the list contains neither zinc oxide nor titanium dioxide, the two mineral filters.
That matters in two ways. Chemical filters are usually what let a sunscreen go on clear, because there's no white mineral pigment to show. And if you specifically want a mineral-only sunscreen, perhaps because chemical filters have stung your eyes before, none of the four COSRX sunscreens at Sleepy Hello is mineral-only. The Aloe Soothing Sun Cream adds titanium dioxide to its chemical filters, the tone-up contains titanium dioxide as a tinting pigment, and the stick is chemical too.
The tube and COSRX's listing both read SPF50+ PA++++. PA is the Korean and Japanese rating for UVA protection, and PA++++ is the top grade.
Ultra-Light, Aloe Soothing, tone-up or stick: how the four compare
COSRX Aloe Soothing Sun Cream SPF50+ PA+++, 50 ml is the one COSRX makes with dehydrated skin in mind. COSRX describes it as a lightweight, moisturizer-like cream, and our product page highlights a 55,000 ppm aloe complex. Its first ingredients are water, ethylhexyl methoxycinnamate (a UV filter), glycerin, propylene glycol and cyclopentasiloxane, a silicone that evaporates. The ingredient list also includes alcohol (ethanol) and fragrance, with fragrance components such as limonene, linalool and geraniol named at the end. Its PA rating is one grade lower, PA+++. It's $10.99 for 50 ml, checked October 2026, and COSRX directs you to apply a generous amount as the last skincare step, 30 minutes before sun exposure.
COSRX Aloe 54.2 Aqua Tone-up Sunscreen, 50 ml is SPF 50+ PA++++ with a tint. The name comes from its first ingredient, aloe barbadensis leaf water at 54.2%, according to COSRX's Korean listing. Its chemical filters are homosalate, ethylhexyl salicylate, diethylamino hydroxybenzoyl hexyl benzoate, bis-ethylhexyloxyphenol methoxyphenyl triazine and terephthalylidene dicamphor sulfonic acid. Titanium dioxide appears with its pigment code (CI 77891), alongside red and yellow iron oxides, and those pigments are what give a tone-up sunscreen its brightening tint. Niacinamide, sodium hyaluronate, allantoin and vitamin B12 are the highlighted extras, and no fragrance is listed. It's $11.99 for 50 ml, checked October 2026. Apply it generously at least 15 minutes before sun exposure and reapply at least every two hours.
COSRX Airy-Light Invisible Sun Stick SPF50+ PA++++, 19 g is a solid stick you wind up with a dial at the base. According to COSRX's Korean listing, the base is a wax-and-powder blend (methyl methacrylate crosspolymer, synthetic wax, silicones, light esters, silica, ozokerite and ceresin), and the filters are diethylamino hydroxybenzoyl hexyl benzoate, ethylhexyl triazone, polysilicone-15 and bis-ethylhexyloxyphenol methoxyphenyl triazine. That makes it a chemical sunscreen as well. COSRX describes the finish as lightweight, non-greasy and soft-matte with a powdery feel, and the product description names oily skin and excess sebum among its targets. Ceramide NP, niacinamide, zinc PCA, panthenol and sodium hyaluronate sit toward the end of the list, and no fragrance is listed. It's $15.99 for 19 g, checked October 2026.
Zinc PCA, which our stick page lists as the main active, is a zinc salt often used in products for oily skin. It isn't zinc oxide and doesn't make the stick a mineral sunscreen.
Which COSRX sunscreen is best for oily skin?
For oily skin, the Ultra-Light Invisible Sunscreen is the best of the four for daily wear, and the Airy-Light stick is the best for top-ups. The Ultra-Light has a watery aloe base, no heavy oils or butters near the top of its list and no fragrance, and COSRX describes its finish as non-greasy. The stick is the only one COSRX describes as matte, which suits a shiny T-zone by mid-afternoon.
The Aloe Soothing Sun Cream is the least obvious choice for oily skin. COSRX positions it for dehydrated skin and calls it moisturizer-like, and its ingredient list includes alcohol and fragrance, which oily but easily irritated skin may not enjoy. The tone-up sits in between: COSRX calls it soft, airy and non-greasy, but you'd buy it for the tint rather than for shine control.
Combination skin can follow the same logic. If your cheeks feel tight under a light sunscreen, add a moisturizer underneath rather than switching to a heavier sunscreen. Our guide to Korean sunscreen for oily skin covers options beyond COSRX.
Does COSRX sunscreen leave a white cast?
The Ultra-Light Invisible Sunscreen and the Airy-Light stick are the least likely to leave a white cast, because neither contains a mineral filter. COSRX describes both as transparent with no white cast, and says the Ultra-Light looks invisible across skin tones.
The Aloe Soothing Sun Cream contains titanium dioxide, but it sits in the middle of the list, after the chemical filters, and COSRX says it leaves no visible white cast. The Aloe 54.2 tone-up is different on purpose. COSRX describes a naturally tinted, more even-looking finish that leaves a soft appearance without a white cast. Any tone-up sunscreen still adds a tint to bare skin, though, and because that tint comes in a single shade, it can look lighter than medium and deep skin tones. If you want no visible change at all, skip the tone-up.
COSRX sunscreen cream vs stick: which should you reapply with?
Use a cream for the morning application and the stick for reapplying. A cream lets you measure a generous amount and spread it evenly, while a stick makes it hard to know how much you've applied, and one quick swipe leaves a thin layer. Our guide to how much sunscreen to use on your face explains the amount behind the number on the label.
The stick earns its place at midday. You can reapply it without getting your hands wet, it fits in a pocket, and COSRX says the stick is made for easy reapplication away from home, including during outdoor activities. The directions say to apply it evenly to exposed areas and reapply often, especially after sweating, swimming or toweling; they don't give a number of swipes. Going over each area several times rather than once is our suggestion for a more even layer.
If you only buy one, buy the Ultra-Light, since a tube can cover both jobs and its directions say to reapply every two hours. The stick costs about 84 cents per gram against 22 cents per ml for the Ultra-Light tube, which is the price of portability.
Quick answers
Is COSRX sunscreen non-comedogenic?
COSRX doesn't make a non-comedogenic claim for any of these four sunscreens on the pages we checked, and no ingredient list can promise that a sunscreen won't clog your pores. The Ultra-Light has the simplest base for breakout-prone skin: watery, fragrance-free and without heavy oils. The stick relies on waxes such as synthetic wax, ozokerite and ceresin to stay solid, so if waxy products tend to leave you congested, keep it for small top-ups. Introduce one new sunscreen at a time so you can tell what's behind any change.
Is COSRX sunscreen water resistant?
None of the four product pages claims water resistance. The Ultra-Light, Aloe Soothing and stick directions say to reapply after swimming, sweating or towel-drying, and the tone-up's say to reapply at least every two hours, so think of all four as everyday sunscreens rather than beach or sports formulas.
Does the Ultra-Light Invisible Sunscreen contain fragrance or alcohol?
The ingredient list on COSRX's Korean store includes no fragrance and no ethanol. Behenyl alcohol and arachidyl alcohol appear, but those are fatty alcohols, waxy thickeners that don't have the drying effect of ethanol.
Can you wear COSRX sunscreen under makeup?
Yes. The Ultra-Light and tone-up directions both say to wear them alone or under makeup, and the Aloe Soothing Sun Cream directions say to apply it before base makeup. Giving the sunscreen a few minutes to settle before foundation is a sensible habit.
Where can you buy COSRX sunscreen in the US?
All four are at Sleepy Hello, with prices checked October 2026:
Tocobo Bio Watery Sun Cream is a light, dewy all-chemical SPF 50; fine for oily skin if you accept some sheen, with the matte sun stick for reapplying.
