This the real deal. Powerful, medical grade Vitamin C.
'Medical grade' means that it is licensed to penerate deep into the skin, making Obagi professional Vitamin C significantly more active and effective than it's closest competitor - Skinceuticals CE Ferulic.
You can use less and achieve more with this powerful antioxidant serum.
 
Use a couple of drops daily on clean skin, avoid eyes.
Allow to penerate then continue with a moisturiser if required.
Don't mix with Retinol or Tretinoin.
I prefer to use it in the mornings, to brighten my complexion and heal.
