Consider it if you want a portable solid format and can apply enough product evenly according to the label.
Based on brand information and published sources, not a hands-on review.
01 / TEXTURE
A solid sunscreen stick shown with its removed cap in official product artwork. The clear-finish description is the brand’s; the package photo is not our wear or white-cast test.
03 / YOUR ROUTINE
Apply liberally 15 minutes before sun exposure. Reapply after 80 minutes of swimming or sweating, immediately after towel drying, and at least every two hours. Follow the Drug Facts on your U.S. package.
For external use only. Do not use on damaged or broken skin. Keep out of eyes and rinse with water if contact occurs. Stop use and ask a doctor if rash occurs. If swallowed, get medical help or contact a Poison Control Center right away. For children under 6 months, ask a doctor. Protect from excessive heat and direct sun.
CHOOSING THIS FORMULA
No. The label gives three reapplication triggers: after 80 minutes of swimming or sweating, immediately after towel drying, and at least every two hours. If you towel off before 80 minutes have passed, the towel-drying instruction still applies. Water resistant is a specific label claim, not a promise of all-day protection.
The solid format is convenient to carry and apply directly, but portability does not measure coverage. The U.S. label says to apply liberally and gives no fixed number of swipes. Do not treat one quick pass as a measured sunscreen amount or use the ease of carrying it as a reason to skip reapplication.
The checked U.S. Drug Facts list avobenzone 2.8%, homosalate 11%, octisalate 4.5% and octocrylene 7.5%. The package displays Broad Spectrum SPF 50 and water resistance for 80 minutes. A similar Korean-market sun stick or PA claim should not be substituted for this U.S. label.
Both are U.S. sunscreens, but the formats and water-use instructions differ. COSRX is a stick with an 80-minute water-resistance claim. LANEIGE’s reviewed EX label is for a cream and directs users to choose a water-resistant sunscreen when swimming or sweating. That is a useful choice criterion for water activities; it is not an efficacy ranking based on texture.
The label says to apply liberally 15 minutes before sun exposure. Reapplication follows a separate schedule: after 80 minutes of swimming or sweating, immediately after towel drying, and at least every two hours. Follow the other sun-protection measures on the label, too.

COSRX is a 19 g stick labeled water resistant for 80 minutes. The current LANEIGE EX cream label does not make that claim and directs users to use a water-resistant sunscreen for swimming or sweating. Compare those instructions and the formats, then apply and reapply as labeled.

Calculations use complete ingredient lists for the stated market and product version. Listed names do not establish concentrations, equivalent effects or allergy suitability.
Explore products in the same use group with overlapping ingredient lists, then compare their texture, directions and ingredient differences.
Candidates share the page’s language, market context and use group and have a complete ingredient list available. Names are normalized for spacing and reviewed synonyms; duplicate names count once.
The default order divides shared names by all distinct names across both lists: 10 shared names out of 20 distinct names gives 10 ÷ 20. You can instead order by the number of shared names. Up to five candidates are shown.
Ingredient overlap does not establish equivalent effects or a cheaper substitute. Concentrations, ingredient order, finished-product tests and feel are not part of this calculation. Missing lists are not treated as missing ingredients.
