A Complete Shield That Feels Like Nothing

Get the highest sun protection available without the heavy, greasy feel. It absorbs instantly, leaving skin ready for makeup or just a fresh, bare face.

Protects Against More Than Just the Sun

Your skin faces blue light from screens and pollution daily. This serum defends against these modern aggressors too, for comprehensive daily armor.

No More White Cast or Pilling

Finally, a high-SPF formula that blends in clear on every skin tone and doesn't ball up under makeup. Users say it's 'truly invisible.'

Hydrates While It Protects

Unlike drying alcohol-based sunscreens, this one pumps moisture into your skin all day. It feels 'comfortable and plumping,' not tight.

Makes Your Makeup Look Better

Acts as a perfect, smoothing primer. Makeup applies evenly and 'stays put longer' without separating over sunscreen.

Simplifies Your Morning Routine

One product replaces serum, moisturizer, and sunscreen. It's the 'easy, all-in-one step' busy people trust.

Gentle Enough for Sensitive Skin

Fragrance-free and non-comedogenic, it's made for skin that reacts easily. No irritation, just calm, protected skin.

The Trust of Japanese Science

This isn't just a sunscreen; it's a meticulously engineered serum from a 70+ year old Japanese brand known for rigorous quality. You're getting proven, reliable technology.

4. **Zero White Cast Technology** — Formulated to be completely transparent on all skin tones, verified through rigorous testing.

5. **Moisture-Boosting Complex** — Infused with Hyaluronic Acid and botanical extracts to hydrate skin throughout the day, preventing the tight, dry feeling some sunscreens cause.

6. **Makeup-Friendly Base** — Creates a smooth, non-pilling canvas that helps makeup 'last longer' and apply evenly, as noted in user trials.

7. **Non-Comedogenic & Fragrance-Free** — Dermatologically tested in Japan to not clog pores. Contains no added fragrance, ideal for sensitive skin.

8. **Japanese GMP Certification** — Manufactured in a facility adhering to Japan's strict Good Manufacturing Practice standards for cosmetic safety and quality.

9. **40ml Precision Bottle** — The bottle and pump are designed to dispense the perfect single-use amount, minimizing waste and ensuring consistent application.

1. After your morning skincare routine (toner, essence, moisturizer), dispense one pump of serum.

2. Apply evenly to your entire face, neck, and décolletage. Gently pat to absorb. No white cast.

3. Use as the final step in your daytime routine, before makeup if worn.

4. Reapply every 2-3 hours if exposed to direct sunlight for extended periods.

Timeline Expectations

- **Week 1:** Initial feel is 'lightweight' and 'not sticky.' Makeup applies smoothly over it. Skin feels protected without the heavy sunscreen sensation.

- **Week 2-3:** Cumulative protection helps skin look 'less tired' and 'more even-toned' by shielding against daily environmental stress. The 'invisible finish' becomes a non-negotiable part of your routine.

- **Week 4+:** Long-term, consistent use supports skin's defense system. Users report their skin 'stays calmer' and maintains a 'healthier-looking glow' with fewer concerns about sun damage and pollution-related dullness.

Kose Infinity was born from a simple frustration: why should sun protection feel heavy, greasy, or like a chore? In Japan, where skincare is a daily ritual of respect for your skin, Kose scientists set out to build a serum that protects like a shield but feels like nothing. They combined their 70+ years of Japanese cosmetic science with a patented Multi-Protection System, selecting each ingredient for a single purpose: to defend against the modern world's daily aggressors—UVA/UVB rays, blue light, and pollution—without compromising on a luxurious, weightless feel. Every batch is produced in a Japanese GMP-certified facility, adhering to the strictest quality controls. The result isn't just a sunscreen; it's the top-ranked multi-protection serum in its category, trusted by discerning users who refuse to choose between high-level defense and a flawless finish.

The Kose Infinity Multi-Protection Day Serum UV SPF 50+ PA++++ features a sophisticated blend of ingredients designed to provide comprehensive skincare and sun protection. Key components include ethylhexyl methoxycinnamate (octinoxate) and bis-ethylhexyloxyphenol methoxyphenyl triazine (Tinosorb S), which are broad-spectrum UV filters that shield against both UVA and UVB rays, offering high SPF 50+ and PA++++ protection to prevent sun damage and premature aging. The formulation also incorporates hyaluronic acid and sodium hyaluronate, which are humectants that attract and retain moisture in the skin, enhancing hydration and plumping effects for a smoother, more supple complexion. Additionally, it contains tocopherol (vitamin E), an antioxidant that helps neutralize free radicals from environmental stressors, reducing oxidative stress and supporting skin health. Other ingredients like butylene glycol and glycerin serve as emollients and solvents, improving texture and ensuring even application, while dimethicone provides a silky finish and helps lock in moisture. This combination not only delivers robust sun defense but also nourishes the skin, making it suitable for daily use to maintain a radiant and protected appearance.
