KAHI Tone Up Sun Serum 50ml - Glow & Guard

KAHI Water Holding Tone Up Sun Serum SPF50+ PA++++

Sunscreen, serum, and tone corrector. One lightweight step.

A multi-functional cosmetic with SPF50+ PA++++ that protects against UV rays, brightens skin, and reduces wrinkles — naturally evening out tone imperfections for a youthful, radiant look. The first sunscreen from KAHI, and it carries all the innovation that made the Multi Balm famous — advanced technology, Jeju-sourced actives, and a texture that feels like nothing on the skin while doing everything. 

The UV filter system is one of the most comprehensive available — combining five advanced chemical and physical filters: Ethylhexyl Triazone (the most photostable and effective UVB filter globally), Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus — premium UVA 1 filter), Drometrizole Trisiloxane (broad UVA and UVB coverage), Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (Tinosorb M — one of the most advanced broad-spectrum filters available), and Titanium Dioxide (mineral UVB and UVA II protection). Together they deliver SPF50+ PA++++ broad-spectrum, photostable protection that holds up through heat, humidity, and perspiration. Patented water-boosting and Polymeric High Temper technology ensures long-lasting SPF protection even in humid conditions. 

A triple functional cosmetic for skin brightening, wrinkle improvement, and sun protection — its shade naturally corrects tone imperfections for a youthful-looking complexion. The subtle tone-up tint is achieved through Mica and Titanium Dioxide, which create a natural soft-focus brightening effect that evens out dullness without any visible coverage or white cast. Niacinamide brightens, minimizes pores, and controls sebum. Adenosine supports collagen production and smooths fine lines. Tocopherol (Vitamin E) provides antioxidant protection. Portulaca Oleracea (Purslane) Extract — with potent antioxidant and skin-soothing properties — calms redness and protects against environmental stress. Nasturtium Officinale (Watercress) Extract nourishes and defends skin against sun damage. Sphingomonas Ferment Extract — a biotechnology-derived active — reinforces the skin barrier and improves moisture retention. VP/Eicosene Copolymer provides flexible long-wear hold. Caprylyl Methicone delivers the signature serum-like, silky texture that sets this sunscreen apart from any conventional formula. Propanediol and Glycerin maintain comfortable hydration throughout the day. 

Lightweight, non-sticky, silky texture that absorbs quickly without any greasy residue. No white cast. Water- and sweat-resistant for all-day wear.
