KIYOSENSE combines six molecular weights of hyaluronic acid with individually sealed 1ml ampoules. Instead of relying on one type of hyaluronic acid in a repeatedly opened bottle, 6D gives you a more complete hydration system with a fresh, precisely portioned application every time.
Every ampoule stays sealed until you open it. That means no repeatedly opening the same bottle, no dipping a dropper back into the product, and no guessing how much to apply. Simply open one fresh 1ml dose and use it.
The serum delivers an immediate hydration step that leaves skin feeling softer, smoother, plumper and more replenished. With regular use, well-hydrated skin can also appear more supple and fine dehydration lines can look softer.
Yes. Use LUMINO PRO on clean, dry skin first, then apply one freshly opened 1ml ampoule after your LED session. This creates the complete KIYOSENSE ritual: LED treatment first, 6D hydration second.
Each box contains 30 individually sealed 1ml ampoules. At one ampoule per day:
1 Box = 30 days
3 Boxes = 90 days
6 Boxes = 180 days
The 6-box option provides the best one-time value at $25 per box.

The KIYOSENSE 6D Difference
Hydration Changes As Skin Changes. 6D Hyaluronic Acid Goes Further.
As skin becomes drier, less supple and less resilient, fine lines, rough texture and loss of bounce can become more noticeable. KIYOSENSE is formulated with six molecular weights of hyaluronic acid in one freshly sealed 1ml ampoule to replenish moisture and leave skin looking plumper, smoother, softer and refreshed.

What 6D Hydration Does
More Than Moisture. Hydration You Can See and Feel.
Plumper, Fuller-Looking Skin
Restores hydration where skin can begin to look flatter, drier or less bouncy for a fuller, more supple appearance.
Softens Fine Lines & Dehydration Creases
Plumps dry areas with moisture so fine lines and creases appear smoother, softer and less pronounced.
Restores Bounce & Suppleness
Replenishes thirsty skin so it looks softer, springier, smoother and more resilient.
Smooths Rough, Uneven Texture
Replenishes dry, thirsty skin so the surface looks softer, smoother and more refined.
Revives Dull, Tired-Looking Skin
Restores moisture and freshness for skin that looks brighter, healthier and naturally more luminous.
How 6D Hyaluronic Acid Works
Six Molecular Weights.
One Complete Hydration Formula.
The 6D formula combines six molecular weights of hyaluronic acid, ranging from 1500 kDa to 50 kDa. Larger HA molecules complement surface moisture while progressively smaller molecular weights complete the formula for a more layered, lightweight and comprehensive hydration experience.
