How to use a serum
Apply once or twice daily after cleansing, toning and exfoliating. Dispense 2–3 drops and add to your favourite moisturiser or serum. May also be used alone. For daytime, follow with a broad-spectrum sunscreen rated SPF 30 or greater. May be applied around the under-eye area.
The C15 Super Booster contains a high concentration of vitamin C, which loses its potency when exposed to light and air. Using it within 3 months guarantees its effectiveness, when used after this period the product may not be as potent. Unopened the shelf life of C15 Super Booster is up to one year.
Vitamin C is not generally an ingredient that causes skin irritation, but if your skin appears red or inflamed we recommend that you reduce the frequency of use or temporarily stop.
Most of our products are colourant and fragrance free. What you smell is the scent of one or more of the ingredients (raw materials) used to produce this product. This scent can vary from batch to batch.
You may notice from time to time that the shade can vary on your C15, especially after use. One of the challenges of having an irritant-free line is that we cannot use coloring agents or dyes to ensure a precise, consistent color from batch to batch. Because of this, there can be color variations with some of our products. Since judging color can be subjective, we have provided a color swatch below that shows the acceptable range of colors when used within three months after opening, and six months unopened.
