Keep skin healthy and protected against environmental damage with the Professional-C Serum 20% from Obagi Medical.
 
This concentrated formula infuses the skin with a generous 20% concentration of Vitamin C to rejuvenate and brighten the skin while providing effective protection against environmental stressors. While the serum works hard to encourage the growth of collagen and elastin fibres, Hyaluronic Acid retains long-lasting moisture to prevent dryness, leaving the skin more even and supple every time.
 
Suitable for all skin types, apply five to seven drops of the serum to cleansed skin on the face, neck and decollete using fingertips. Use in the morning and always follow with sunscreen.
