C Plus Serum 7S

C Plus Serum 7S is suitable for most skin types, including sensitive skin. It is dermatologically tested to be gentle on skin.

However, it is not recommended for use on areas with active acne to minimise the risk of irritation.

If you have sensitive skin, start with a lower amount and reduce frequency of use. As your skin becomes accustomed, gradually increase frequency of use and application amount to the recommended 10 to 12 drops.

It is also advisable to perform a patch test before use by applying a small amount to the back of your ear or inner arm to check for any signs of reaction.

We recommend starting the use of C Plus Serum 7S around your mid-20s, when natural collagen production starts slowing down.

Our skin's collagen starts breaking down at a faster rate when we turn 25. Apply two to three times a week and increase gradually as your skin adjusts to the product.

Yes, a warming sensation is normal when using a high-potency Vitamin C formula like C Plus Serum 7S.

This is due to its anhydrous (water-free) formula, which helps stabilise the high concentration of Vitamin C. When the formula comes into contact with moisture on the skin, a slight release of heat may occur, resulting in a gentle warming sensation. This warming effect also helps to soothe the mild tingling sensations that could arise from concentrated Vitamin C formulas.

As your skin adapts to the product, it is normal for the warming sensation to fade.

Yes, we recommend using C Plus Serum 7S during the day or at night. When used in the day, Vitamin C acts as an antioxidant that protects the skin against free radical damage.

For optimal daytime skin protection, follow with a generous amount of sunscreen to double up on your sun protection efforts.

It is normal for a high‑potency Vitamin C formula like C Plus Serum 7S to turn yellow over time with constant exposure to air.

This is a natural characteristic of formulas with a high Vitamin C content. The colour change does not indicate reduced effectiveness. C Plus Serum 7S is formulated to remain effective despite this natural colour variation, and product quality is not affected under normal usage conditions.

To slow the colour change, we recommend the following good practices:
- Close the bottle tightly after each use
- Store in a cool, dry place away from direct sunlight
- Use within 6 months after opening

Visible improvements can be seen as early as 14 days with C Plus Serum 7S, based on clinical trial results.

Individual results may vary depending on your current skin condition and consistency of use. We recommend consistent daily use for at least one month to see noticeable improvements.

Our products are generally safe for pregnant women. However, as each individual's condition is different and every pregnancy is unique, we recommend that you check and get your doctor's opinion for assurance. If you are allergic to or concerned about certain ingredients, always check the product label.
