Obagi Professional-C with 20% Vitamin C

Vitamin C is a powerful antioxidant that works to protect your skin from free radicals which are generated in your skin during and after exposure to UV light from the sun throughout both the winter and the summer in 2021. In its L-ascorbic acid form, vitamin C can soak through the layers of your skin to offer its beneficial mechanism of action to the deeper layers. Here, its antioxidant properties can have a more pronounced effect in combating the visible signs of ageing, such as fine lines and wrinkles. By adding the Obagi Professional-C Serum to your skincare routine, your skin will enhance visibly. Combine the Obagi Vitamin C Serum with other Obagi skincare products to obtain a maximum effect. 

Topical application of vitamin C in the Obagi-C serums not only protects your skin from UV related damage and enhanced ageing, it plays a vital role in collagen production in your skin. Collagen is responsible for your skin's firmness and elasticity and so Obagi Professional-C 20% is designed to improve skin’s plumpness and promote a healthy youthful glow.

Fortified with Hyaluronic Acid

To enhance the skin-firming effects of L-ascorbic acid, the Obagi Professional-C Serum also contains hyaluronic acid. This is a clever molecule that binds to water in your skin and locks it in, preventing dryness and further encouraging a plump and rejuvenated look to your skin.  

Effective Against Hyperpigmentation

Obagi Professional-C Serum 20% works to brighten the appearance of hyperpigmented skin and dark spots, to push a radiant and even skin tone. Not only does this serum improve skin tone, but the Obagi-C Serum works to enhance the skin’s texture as well.

Why is Vitamin C important?

Vitamin C belongs to an important group of antioxidants which fight the free radicals that age the skin. Studies have shown topical Vitamin C, in the most effective form (L-ascorbic acid), can help improve sun protection, repair sun damaged skin, reduce fine lines, stimulate collagen building and potentially reduce discoloration of the skin.

When Should I Use Vitamin C Serums?

Vitamin C can be used twice a day under makeup or sun block. It is easily absorbed by the skin to give 24 hour protection against free radical damage. When used under sun block it will provide additional protection against sun damage and environmental stress on the skin so is essential for individuals with an out door lifestyle.

How is the Obagi Professional C Serum different from other Vitamin C products?

The Obagi Professional C Serum patented formulation, using proven ingredients, provides a simple to use system for brighter, more radiant skin. While many Vitamin C products simply moisturize the skin's surface, the Obagi Professional C Serum penetrates to all layers of the skin, effectively delivering more Vitamin C than other brands.

What are Antioxidants?

Antioxidants are the skin’s natural anti-aging solution. They act by neutralising the free radicals that cause damage to the collagen in the dermis layer. Free radical attack results in a loss of elasticity, discolouration and premature aging of the skin through a process known as “photo-aging”. As we age and our exposure to harmful environmental factors increases, our bodies no longer produce enough antioxidants to halt the damage caused by these radicals.

  • Apply 5 to 7 drops to the face, neck and chest using fingertips.
  • Apply to cleansed skin in the morning before sunscreen and makeup application.
  • A slight tingling may occur in some people, which diminishes with continued use.
