Isehan Sunkiller Water Essence Alcohol-Free SPF50+ PA++++ 50g

Isehan Sun Killer Perfect Water Essence N 50g SPF50+ PA++++ is an alcohol-free water-essence sunscreen for sensitive, dry, and reactive skin that experiences stinging, redness, or tightness with conventional Japanese sunscreens — most of which use ethanol as a key ingredient to achieve their quick-dry, lightweight finish. This formula achieves the same lightweight water-essence texture without any alcohol content.

• SPF50+ PA++++ — maximum UV protection for face and neck daily use
• Completely alcohol (ethanol) free — eliminates the primary irritant in most lightweight Japanese sunscreens
• Water-essence texture — lightweight, fast-absorbing, no residue despite the absence of alcohol
• Fragrance-free — removes a second common contact irritant for reactive skin
• Suitable from first-use for skin that has previously reacted to other Japanese sunscreens
• 50g — standard single-person face-and-neck supply

How it works: In most lightweight Japanese sunscreens, ethanol performs two functions: it dissolves certain UV filter molecules that would otherwise be difficult to suspend in a water base, and it accelerates evaporation creating the quick-dry sensation. Removing alcohol requires reformulating the entire solvent system to keep UV filters suspended and the texture lightweight — which is technically more complex than simply omitting it, and why genuinely alcohol-free high-SPF water textures are rare in the market.

Sun Killer vs Canmake Mermaid Skin Gel for alcohol-free SPF: Both are alcohol-free SPF50+ sunscreens in lightweight textures. The Sun Killer Perfect Water Essence is a thinner, more water-like texture suited to skin that even finds gel sunscreens slightly too emollient. The Canmake Mermaid Skin Gel has a slightly thicker gel consistency with botanical soothing extracts. For the most reactive, alcohol-sensitive skin, try the Sun Killer first.

Known in Japan as サンキラー パーフェクトウォーターエッセンスN 50g.
