Vitamin C Serum Antioxidant with Hyaluronic Acid

We recommend starting Vitamin C Serum at 2.5% for one month; move up to 5% the second month; 10% the third, and continuous months. When you order a Vitamin C subscription the increase in potency will be shipped automatically to you. The 10% level is the maximum strength, when you are at the 10% level, we continue to ship this level. If, at any time, you experience irritation, please contact us so we can ship out a replacement bottle of the prior, lower, percentage. To Use: Apply in the morning to a clean, dry face and décolletage and back of hands. If you're also using our Facial Lotion with Green Tea and Grapeseed Oil, apply the Vitamin C Serum prior to applying the Facial Lotion.  Allow to dry approximately 10 minutes before applying additional cosmetics. If using in the morning, we strongly recommend using sunscreen. Please note the serum may stain light fabrics and hair. Avoid eyes and sides of nostrils when applying.
