This is three products in one well-built step. It uses a next-generation four-filter UV system — including Mexoryl filters not available in the US — for genuinely strong SPF50+ PA++++ protection; it carries a treatment-level 1% tranexamic acid with niacinamide and glutathione for real brightening; and a purple tone-up tint instantly neutralizes sallowness. Protection, treatment and tone-up together.
A genuinely strong three-in-one sun essence — a next-generation four-filter UV system delivering robust SPF50+ PA++++, a treatment-level 1% tranexamic acid with niacinamide and glutathione for real brightening, and a purple tone-up tint that neutralizes sallowness on contact. Fragrance-free, lightweight, and well-built for daily brightening sun care.
A spring 2026 launch with very few independent reviews. The grade is anchored in formulation analysis and Klairs's sun-care record, and may shift as feedback builds.

Plenty of sunscreens advertise a high SPF number and then quietly underdeliver on UVA — the longer-wavelength radiation that drives photoaging, dark spots and the slow, invisible damage you do not notice until years later. SPF measures UVB; UVA protection is a separate question, and it depends entirely on which filters a formula chooses. That is the real story of this Klairs sun essence, and it begins with a filter system most shoppers in the United States will not recognize.
The essence runs a four-filter system built from next-generation organic UV filters not available in the US sunscreen system — including two Mexoryl-type filters and a triazone. These are precisely the filters known for strong, photo-stable, broad-spectrum coverage with particularly robust UVA performance, and together they deliver a genuine SPF50+ PA++++ rating. PA++++ is the highest UVA grade on the Asian rating scale, and it is the part that actually matters for the photoaging and pigmentation this product positions itself against. If you have ever wondered why some K-beauty and European sunscreens feel a generation ahead of what is on a typical drugstore shelf, this filter chemistry is a large part of the answer — the newer organic filters are simply more efficient and more photo-stable than the older ones still doing most of the work elsewhere.
Klairs did not stop at protection. The essence carries tranexamic acid at 10,000 ppm — a meaningful 1% dose, treatment-level rather than token. Tranexamic acid interrupts the signaling that drives pigment production, making it one of the more effective topical actives for dark spots and uneven tone, and pairing it inside a sunscreen is genuinely logical: it fades existing pigment while the SPF blocks the UV that creates new pigment. Niacinamide sits high in the formula adding barrier support and a second brightening mechanism, glutathione adds a third, and ectoin reinforces the defensive, hydration-holding side that gives the 'supple' essence feel its name. On top of all that sits a purple tone-up tint — and the tint is not a gimmick. Purple sits opposite yellow on the color wheel, so a sheer purple veil visually neutralizes the yellow sallowness many complexions show, for an immediate brightened look. It is real color theory, cosmetic and temporary, but real.
What it feels like on application is a light, moist essence rather than a sunscreen — it spreads easily, absorbs to a comfortable, slightly dewy finish, and sits well under makeup with no white cast, sting or heaviness. No fragrance has been added to the formula. A few limitations are worth flagging, modest as they are. The purple tint can leave a faint cast if you over-apply it, so it rewards an even hand. The formula contains silicone-based filters and is not fungal-acne safe. And while the 1% tranexamic acid genuinely contributes to brightening, a sunscreen is not a full substitute for a dedicated leave-on treatment — for significant pigmentation, a focused night treatment still does the deeper work; this essence's strength is doing protection and a brightening assist in one daytime step. As with any SPF, it only works at the full two-finger dose, and the 50 mL bottle empties within a month or two at that amount.
A clear-eyed sense of the order of priorities helps, though. The advanced filter system is the reason to buy this; the tranexamic acid and the tone-up tint are genuine, well-executed bonuses layered on top. If you read it that way — a serious sunscreen that also brightens, rather than a brightening treatment that happens to have SPF — your expectations will line up with what the bottle actually delivers.
One practical caveat about the tint is worth holding onto. The purple veil that neutralizes sallowness is genuinely flattering at the right dose, but a tinted product punishes a heavy hand more than a clear one does — pile it on and the cast can read as a faint lavender film rather than simply brighter skin. The fix is the same as the fix for any sunscreen: an even, deliberate full-face application rather than a hurried smear.
Costing around $25, the value is good for what amounts to three products folded into one well-built step. Klairs has a long line of cosmetically elegant facial sunscreens behind it, having formulated gentle K-beauty since 2010, and this 2026 sun essence reflects a current direction of building treatment actives into sun protection. This is a recent release, so the review pool is small — roughly 120 ratings averaging 4.4 stars — so the early read leans on the formula, with users praising the strong broad-spectrum protection, the comfortable moist-essence texture and the immediate brightened look the tint provides. Provided you want serious UVA protection plus a brightening assist in a single daytime step, and you commit to applying it at a real dose, this is a smartly built choice that quietly does more than its SPF number alone would suggest.

| Ingredient | Function | Evidence |
|---|---|---|
| Advanced UV Filter System (Drometrizole Trisiloxane, Ethylhexyl Triazone, DHHB, Terephthalylidene Dicamphor Sulfonic Acid) | A four-filter system built from next-generation organic UV filters not available in the US sunscreen system — including two Mexoryl filters and a triazone. Together they deliver genuinely strong, photo-stable broad-spectrum SPF50+ PA++++ protection, with particularly robust UVA coverage, the wavelength that drives photoaging and dark spots. | Regulator-approved for Sun Damage · limited certainty |
| Tranexamic Acid (1%) | Listed at 10,000ppm, a meaningful 1% dose — tranexamic acid interrupts the signaling that drives pigment production, making it one of the more effective topical actives for dark spots and uneven tone. Pairing it inside a sunscreen is logical: it fades existing pigment while the SPF blocks the UV that creates new pigment. | Limited for Hyperpigmentation |
| Niacinamide | Sits high in the formula, brightening tone and reinforcing the barrier — it works with tranexamic acid on the discoloration side and helps the essence double as a genuine treatment step, not just a sunscreen. | Emerging for Hyperpigmentation |
| Glutathione | An antioxidant tripeptide adding a third brightening mechanism alongside tranexamic acid and niacinamide, while also helping neutralize the free radicals UV exposure generates — complementing the sunscreen's protective role. | Not yet assessed |
| Ectoin | A natural extremolyte that protects skin cells from environmental and UV-related stress and supports hydration — it reinforces the formula's defensive side and contributes to the 'supple' moist-essence feel. | Not yet assessed |

Make it the closing morning step, over moisturizer, using two finger-lengths for the face and neck to reach the labeled SPF. The purple tint blends in to neutralize sallowness — spread evenly. Top up every couple of hours of sun exposure.
UV protection and the tone-up brightening effect are immediate on application. Genuine fading of dark spots and uneven tone from tranexamic acid and niacinamide is gradual, building over 8-12 weeks of consistent daily use.
The essence's protective strength comes down to its filter selection, which is the variable that actually determines UVA performance. SPF quantifies UVB attenuation only; UVA protection — graded here as PA++++, the top of the Asian scale — depends on having filters with strong long-wavelength absorption. The formula uses next-generation organic filters that are not part of the currently approved US sunscreen system, including drometrizole trisiloxane and terephthalylidene dicamphor sulfonic acid (the Mexoryl filters) and ethylhexyl triazone. These are well characterized for broad-spectrum coverage and photostability — drometrizole trisiloxane in particular is documented for strong, stable UVA protection — which is why a formula built on them can credibly claim robust UVA defense, the wavelength range most associated with photoaging and the worsening of pigmentation.
The brightening side is anchored by tranexamic acid at a stated 10,000 ppm, or 1% — a meaningful, treatment-relevant concentration. Tranexamic acid has a solid evidence base for hyperpigmentation, including melasma, and works by interrupting the plasmin-related signaling between keratinocytes and melanocytes that drives melanin production. Pairing it inside a sunscreen is mechanistically coherent: UV exposure is a primary trigger of pigmentation, so blocking UV and inhibiting the pigment pathway in the same step addresses cause and effect together. Niacinamide adds well-documented brightening via inhibition of melanosome transfer plus barrier support, and glutathione contributes a third mechanism by shifting melanin synthesis toward the lighter pigment type, with topical evidence best described as promising. The purple tone-up tint is straightforward color science — purple and yellow are complementary colors, so a sheer purple layer optically counteracts yellow sallowness for an immediate, temporary brightening effect. Ectoin, a microbial extremolyte, has promising data for protecting skin cells against environmental and UV-related stress. No product-specific clinical trials are available; this assessment rests on the established photochemistry of the filters and the evidence base for the brightening actives.
Daily broad-spectrum sunscreen is one of the most strongly endorsed interventions in dermatology for preventing photoaging, skin cancer and hyperpigmentation. Clinicians familiar with the global sunscreen market often note that the advanced organic filters used here — Mexoryl filters, ethylhexyl triazone and long-UVA filters — provide UVA protection superior to that achievable with the older filter set, which is clinically meaningful because UVA drives both photoaging and pigment formation. Tranexamic acid has gained considerable clinical attention for melasma and stubborn pigmentation, and incorporating a treatment-relevant dose into a sunscreen is consistent with the clinical principle that pigmentation management requires both fading existing pigment and rigorously blocking new UV-induced pigment. Dermatology guidance consistently stresses that brightening results are gradual and depend on daily photoprotection. On pregnancy, sunscreen use is encouraged, while clinicians note that data on topical tranexamic acid in pregnancy is limited, so a plain sunscreen is a reasonable alternative for those who prefer caution. The standard reminders apply: apply the full recommended amount and reapply during sun exposure.
Apply this as the closing step of your morning routine, over moisturizer, using a full two-finger-length dose for the face and neck to reach the labeled SPF50+. Spread the purple tint evenly so it neutralizes sallowness without settling into a visible cast — an even hand matters more here than with an untinted sunscreen. Let it set for a minute before makeup. During sun exposure, reapply every couple of hours; a stick or compact sunscreen makes touch-ups over makeup easier. At night, double cleanse to fully remove the filters, silicones and tint. The 1% tranexamic acid works gradually on pigment, so daily consistency over 8 to 12 weeks is what delivers the brightening payoff.
At around $25 for 50 mL, this sun essence offers strong value because it genuinely combines three functions: a modern, UVA-robust SPF50+ PA++++ sunscreen, a 1% tranexamic acid brightening treatment, and an instant tone-up corrector. A standalone advanced-filter sunscreen and a separate tranexamic acid treatment would together cost considerably more. The 50 mL size lasts roughly one to two months with correct daily application to the face and neck. There is no larger size. Compared with brightening and tone-up sunscreens from other K-beauty and Western brands, which often run $25 to $45, Klairs's pricing is competitive, and the brand's established reputation for cosmetically elegant sun care supports confidence. The value is genuine for anyone who will use the brightening and tone functions, not just the SPF.
Anyone who takes UVA protection seriously and wants genuinely strong, photo-stable broad-spectrum coverage in a comfortable daily formula — the next-generation filter system and PA++++ rating deliver exactly that. It also suits people working on dark spots and uneven tone who like the idea of a treatment-level 1% tranexamic acid and an instant tone-up built into their sunscreen step.
Those who prefer a completely untinted sunscreen, or who find tone-up tints leave a cast on deeper skin tones, may want a clear formula instead. Anyone needing a fungal-acne-safe or silicone-free sunscreen should look elsewhere, and those who prefer caution with topical tranexamic acid during pregnancy should choose a plain sunscreen.

Klairs has a long line of cosmetically elegant facial sunscreens, and this 2026 sun essence reflects a current K-beauty direction — building treatment actives into sun protection. The logic is sound: by combining tranexamic acid brightening with a strong UV filter system, it both fades existing pigment and blocks the UV that creates more.
Dear, Klairs was founded in 2010 in Seoul under Wishcompany, with a philosophy of simple, gentle skincare for sensitive skin. The brand has a long-standing line of well-regarded, cosmetically elegant facial sunscreens.
The purple tint is just a cosmetic gimmick.
The purple tone-up tint is a genuine optical effect — purple sits opposite yellow on the color wheel, so a sheer purple veil visually neutralizes the yellow sallowness and dullness many complexions show, for an immediate brightened look. It is cosmetic and temporary, but it is real color theory, not a gimmick.
A sunscreen with brightening actives can replace a dedicated treatment serum.
This essence carries a meaningful 1% tranexamic acid plus niacinamide, so it genuinely contributes to brightening — more than a typical sunscreen. But for significant pigmentation, a dedicated leave-on treatment used at night still does focused work; this product's strength is doing protection and a brightening assist in one daytime step.
It is a three-in-one daytime step: a broad-spectrum SPF50+ PA++++ sunscreen using advanced UV filters, a brightening treatment with a 1% dose of tranexamic acid plus niacinamide and glutathione, and a purple tone-up tint that instantly neutralizes sallowness for a brighter-looking complexion.
It can contribute genuinely. At 10,000ppm — a meaningful 1% — tranexamic acid is dosed at a level studied for reducing pigment. Combined daily with the SPF blocking new pigment, it helps fade dark spots over 8-12 weeks. For significant pigmentation, pair it with a dedicated nighttime treatment.
Applied at the correct amount and spread evenly, the purple tint blends in to neutralize sallowness with no visible cast. If over-applied or under-blended, a faint purple or pale cast can show, particularly on deeper skin tones, so apply the recommended amount and spread it thoroughly.
Yes — it uses a next-generation four-filter UV system that provides strong, photo-stable broad-spectrum protection, with excellent UVA coverage. Its lightweight, moist essence texture and fragrance-free formula make it comfortable for daily wear. As with any sunscreen, apply the full recommended amount and reapply during sun exposure.
Sunscreen use is recommended throughout pregnancy, and the UV filters here are generally considered safe. However, data on topical tranexamic acid during pregnancy is limited. If you are pregnant or breastfeeding and prefer caution, a plain sunscreen without added brightening actives is a simple alternative — confirm with your healthcare provider.
