The Obagi Professional-C Serum come in 3 strengths. All contain the most effective form of Vitamin C called L-ascorbic acid. This is the 15% Serum for people with less sensitive skins or who have previously used Vitamin C.

Professional-C™ Serums deliver Vitamin C to the skin, providing higher penetration and absorption of Vitamin C than other well known brands. Professional-C™ Serum 20% provided 5 times higher absorption into the skin’s layers 24 hours after application.

Vitamin C targets the visible signs of skin aging caused by environmental stressors.

It helps to:

• Reduce the appearance of photoageing

• Improves the uneven texture and dull skin tone

• Protection from further sun damage

The serums should be used daily and are very helpful under sun protection to reduce the damage cause by UVB/A & heat radiation.
