Smaller particles
for better absorption
of active ingredients
Resistant to light and heat
Optimized blend of
pure vitamin C
which is difficult to stabilize
because of its sensitivity
to light, heat, and oxygen
The secret to the stabilized formula
The specially designed container
We have packed the dropper separately
for hygienic storage and to keep it fresh.
To preserve the freshness and delay the oxidation of pure vitamin C,
which is sensitive to external stimuli such as light, heat, and oxygen,
a special container that allows internal gases to escape
while preventing the ingress of external air is used.
Up to 120 h of antioxidant power*
to fight skin aging
Pure vitamin C products are susceptible to light and heat,
and constant contact with air, including opening
and closing, can make them more unstable and less effective,
but our vitamin C serum is stabilized and can be kept at room temperature
for 120 h without losing its antioxidant power!

How to use
#HighPerformanceVitaSerum
Use it in this order.
After cleansing, apply an appropriate amount to the face
and massage around with fingertips
from the center of the face outwards.
Engage the provided dropper and gently shake from side to side
(do not shake before opening).
Apply to the cheekbone area of both cheeks.
Apply in a rolling motion from cheek to forehead to chin (neck),
following the texture of the skin.
Apply to the C-zone, where elasticity is an issue,
in a C-curl lifting motion to boost skin elasticity.
Apply your next skincare product from the center of the face outwards.
Precautions for storage
and handling of high amounts of vitamin C
*As we do not use fragrances that can cause irritation,
you may notice a strong odor that is inherent to the ingredients,
but this is not a sign of anything wrong with the product,
and you can use it with confidence.
*Use immediately after purchase
and refrigerate (3–10°C) upright.
Because of the nature of vitamin C, gas may be produced.
There may be a 'pop' sound when opening.
The specially designed cap controls the amount of
gas generated inside the bottle when the vitamin C is sealed,
ensuring safe storage.
Shaking the bottle before opening may cause overflow,
so shake the bottle gently from side to side after engaging the dropper.
The empty space in the bottle is reserved for safe use.
Vitamin C products are prone to discoloration due to oxidation
and should be used within two months of opening.
Store away from high temperatures and direct sunlight.
Store in the fridge before and after opening.
