How to use

Apply a few drops to clean skin after toner, morning and night. Tap in until absorbed and follow with moisturiser.
For dark circles, pat an extra drop gently around the orbital bone and let it absorb before eye cream.
After MTS, apply straight after rolling as your calming step. The borneol cools the skin and the barrier ingredients help it settle.
Pairs with Hyal Alpha for extra hydration, and with Vitarect for brightening. ByTheQuality recommends KP Calming + Vitarect for soothing, tone improvement and glow.
Use an opened vial within 1 to 2 weeks. Keep capped, cool and out of sunlight.

Frequently asked questions

What does "KP" stand for?
Vitamin K and Vitamin P, the two headline ingredients. Together they are the classic pairing for dark circles and visible redness.

Is this for the whole face or just under the eyes?
Whole face. Use it everywhere for redness and tone, with extra attention around the eyes if dark circles are your concern.

Can I use it on very sensitive or rosacea-prone skin?
It is made for sensitive skin and tested for irritation. Patch-test behind the ear first, as with any new product, and start with once a day.

Will it work for melasma or deep pigmentation?
Tranexamic acid and niacinamide are two of the most researched ingredients for that, but cosmetics work gradually. ByTheQuality's test measured a modest reduction in pigmentation area. Give it 8 to 12 weeks of consistent use alongside daily sunscreen.

Can I use it with Cellonic Booster or EXO 15698?
Yes. Apply KP Calming Booster last, after the other ampoules, as the soothing layer.
