Cellex-C (UK) Ltd.: Product Application Dos and Don'ts

Do use Cellex-C Patented Formulations once a day, preferably in the morning.
Do use Cellex-C products with a moisturiser.
Do use Cellex-C products with Hydra 5 B-Complex, as the hyaluronic acid enhances the efficacy of vitamin C.
Do use Cellex-C products in the order of viscosity—start with aqueous (water) products and end with thicker products (moisturising or cream formulations).
Do place contact lenses in prior to applying Cellex-C products.
Do apply Cellex-C to a clean dry face.
Do store Cellex-C products in a cool dark place.
Do not be concerned if your Cellex-C slightly darkens over time. The change in colour will not effect the efficacy.
Do not apply Cellex-C eye products to the upper eyelid, or near the outer or inner corners of your eyes. You may apply Cellex-C eye products—in the daytime only—to the lower lids or on the bony structure around the sides of your eye.
Do not be surprised if there is a slight tingling sensation felt when you apply Cellex-C to your skin. This is a normal reaction and will subside within a minute or two. Should the tingling persist after regular use, discontinue use.
Do not use Cellex-C and retinoic acid or AHA’s at the same time. It is best to use these products at alternate times of the day.
