Precautions for storing and handling high-content
Vitamin C products

  1. Gas can be generated due to the nature of vitamin C.
  2. When opening the cap, it may make a sound.
  3. With a specially designed cap to seal vitamin C, it can be safely stored
    by controlling the gas generated inside the container.
  4. If you shake it before opening, it may overflow,
    so shake lightly, from left to right after fastening the pipette.
  5. Extra room in the container has been secured for safe use.
  6. Vitamin C products are recommended to be used within 2 months
    of opening due to easy discoloration caused by oxidation.
  7. Keep it away from high temperatures and direct sunlight.
  8. It is recommended to be stored in the refrigerator
    when it is not being used every day after fastening the pipette.
  9. Keeping it refrigerated can help maintain the freshness of the vitamin C.

* Please use immediately after purchase and store upright in refrigerator
once opened.

*We do not exchange vitamin C serums. We restock our vitamin C monthly and store it in cool temperature until it’s shipped out to you to avoid oxidation. However pure vitamin C has a tendency to leak in hot weather during transit which is beyond our control. Hence pure vitamin C is only product that we do not offer exchange.

  1. Stephen

    I recently bought this product. It has great texture and it’s effective from the first use itself. It has great active ingredient that help the ance and ance scars and even smoothenes your skin at the same time. ⚠️But please read the instructions properly before use, this is very important, it has to be stored in temperature between 3°c to 10°c. Will give another review after a while😘.

    First thing i noticed about this Serum is it’s strange Smell. This serum does not contain fragrances. However, the vitamin C, by nature, has a certain smell that does not affect the potency of the product. Serum has a Watery and bilayer texture that doesn’t feel oily. It glides on the skin beautifully without being sticky or tacky and has a pale yellow colour. It’s a very pleasant warm flush to the skin as you apply to your face and you can instantly feel moisturized. I’m prone to cystic acne when I’m not careful about what I use, as well as frequent smaller breakouts. I have not used any vitamin c product before this other than Goodal vitamin C Serum and cream which has very little amount of active ingredient so I kinda took risk to use this high amount of Ascorbic Acid Serum. I’m literally surprised that this serum does not cause me any purging or breakouts NO single Acne . Also i felt little to no tingling sensation on the 2nd and 3rd day after that my skin was totally fine. My skin feels brighter and firmer especially undereye area. As for dark spots i do have noticed major changes in just 25-30 days. The Glow this Serum brings is unmatched

    Did a pretty good job for hyperpigmentation(pie and pih) and uneven skin tone though I increased the vitamin c strength from 5% to this as my skin got used to it. Very watery and non sticky that gets absorbed instantly. Works well under a thick moisturiser and no piling
