The Koller Milk System: Pure Skin Wellness

At Luna Spas, we have replaced traditional noisy whirlpool jets with the whisper-silent Koller Milk System. This advanced technology supersaturates the water with billions of oxygen-rich micro-bubbles.

How the Collagen Pool Works

FeatureThe Collagen Benefit
Oxygen Micro-SilkMicro-bubbles (50 microns) penetrate the pores to lift away impurities and provide deep hydration.
Natural Collagen BoostThe increased oxygen levels in the water help stimulate natural collagen production and skin cell repair.
Silent RelaxationUnlike standard whirlpools, the Milk System operates with near-zero vibration for a peaceful "Silent Spa" experience.

The Ultimate Skin Ritual ✨

Maximize the anti-aging benefits of your Riho Lima Collagen Pool with this three-step ritual.

🫧 Step 1: Oxygenation

Activate the Koller Milk System. Within seconds, the water transforms into a silky, milky white cloud. Step in and let the oxygen micro-bubbles deep-cleanse your pores and soften the skin.

🌡️ Step 2: Thermal Consistency

As the micro-bubbles collapse, they release heat energy into the water helping prolong the treatment.

🧘‍♀️ Step 3: Total Serenity

Because the system is nearly silent, use this time for mindfulness. Turn off the bathroom lights and allow the optional chromotherapy LEDs to bathe the "milk" in soothing colors for a complete mental and physical reset.
