C15 Essence 7 is suitable for most skin types except for skin with active acne.
If you are concerned about sensitivity, make sure to do a sensitivity test first by applying the product at the back of your ear or the inside of your arm to detect any signs of reaction or allergy. This can help reduce the chance of irritation.
Generally, after the age of 25, our skin's collagen starts to break down at a faster rate than it is being produced. We recommend using C15 Essence 7 to build up a rich reserve of nutrients to enable our skin to produce enough collagen around this age.
The rate at which your skin ages depends on your genetics, environment, skin colour, UV exposure, and lifestyle. You may wish to start using C15 Essence 7 two to three times a week if you are in your twenties and build up the frequency of use from there.
C15 Essence 7 has a high concentration of Vitamin C. To ensure that the active is efficacious, we stabilise it in an anhydrous (water-free) formula. The anhydrous solvent blend releases heat when the product comes into contact with the moisture on the skin surface, which is felt as a mild warming sensation.
Apart from stabilising the formula, the warming sensation also helps to soothe the mild tingling sensations arising from concentrated ascorbic acid formulas.
After using the product for some time, your skin may naturally adapt to the product and the warming sensation will slowly fade.
Yes, in the day, the strong antioxidant properties in C15 Essence 7 can help to neutralise free radical damage contributed by UV exposure. We recommend to use C15 Essence 7 in the day followed by ample amount of sunscreen to double up on your sun protection efforts.
C15 Essence 7 is a high-performance Vitamin C product containing ascorbic acid. While ascorbic acid is a strong antioxidant that offers many skin benefits, it is also prone to oxidation. With time, constant exposure to air may cause oxidation, turning the product yellow. This is normal and common among concentrated Vitamin C products.
Please be assured that under proper/normal usage, the product quality will not be affected. To prevent severe oxidation, a good practice of using Vitamin C products is to tighten the bottle cap immediately after use and store the product in a cool, dry place, away from direct sunlight.
