Cellex CNote: During initial applications of these products, a slight tingling sensation may be experienced. This indicates that the vitamin C is working and generally subsides within a few minutes of application. Your esthetician recommends: For the best results, apply Cellex-C formulations only once during a 24-hour period. If you have sensitive skin, start out using these products every other day and work up to a daily application. Apply in the morning, but if you are using alpha hydroxy, glycolic, or Retinoic acid products, apply Cellex-C at an alternate time of day. Avoid direct contact of these products with clothing, fine linens or lingerie. If you wear contacts, put them in before applying these products. ![]() |
