Why & How to Choose the Right Vitamin C for Your Skin

Vitamin C, also known as ascorbic acid, is the gold star of vitamins and was the first dietary substance associated with curing a disease. Scurvy, a deadly and painful illness, was prevalent before the cure of Vitamin C was discovered in 1747. Citrus fruits became a valuable gift to give to family and friends at the holidays. Today, Vitamin C has become a valuable gift to give to your skin at all times of the year! 

Vitamin C is an important part of a variety of bodily functions including it's effect in the skin. It plays a significant role in bone formation and scar tissue repair. It destroys cell damaging free radicals and is essential for the formation of collagen, our most prolific protein in our body (and skin). It aids in the proper functioning of our nervous system; and it is also involved in the synthesis of hormones, hormone-releasing factors and neurotransmitters. Vitamin C has certainly earned it's gold star status!

Vitamin C and the Skin
Before we talk about it's actions on the skin, we need to thank the scientists - particularly Dr Sheldon Pinnell. The chemistry of Vitamin C is complex. Scientists knew of it's huge potential value in skin care - particularly in protecting and repairing the skin cells from DNA damage caused from sun and pollution damage.
The challenge was creating a formula that remained stable, penetrated properly and worked. Dr Sheldon Pinnell was a  Professor and Chief of Dermatology at Duke University for many years and discovered the key to this mystery. Wisely, he patented his discovery. He also started Skinceuticals, a brand that we have carried at The Summit since shortly after it's founding 1994.
With nearly 40 years of experience researching and developing technologies that help to prevent accelerated skin aging and skin cancer, Dr. Pinnell’s work solidified SkinCeuticals position as a leader in scientifically validated skincare. This research is the reason there is Vitamin C in skin care today. Our skin cells thank you Dr Pinnell!

Collagen & Vitamin C

Collagen makes up 70% of our skin and the loss of collagen results in lines and wrinkles. Vitamin C is essential in the formation and rebuilding of collagen. Collagen is also degraded significantly by sun damage and smoking. Vitamin C is has a key protective effect from sun damage and the effects of smoking. If you want to prevent and/or reverse the signs of collagen loss, Vitamin C is necessary.

Smoother, Healthier Skin Barrier & Vitamin C 

Our epidermis, or skin barrier, is our bodies first line of defence from damaging UV radiation and free radicals that damage our skin cells. It is a complex structure of cells that are continually going through a living and dying cycle in order to protect our skin. Vitamin C is able to destroy free radicals before they can reach the membranes of our cells to start wreck havoc.

The use of effective Vitamin C solutions has proven to reverse the damage to the epidermis making it smoother, brighter and healthier looking and acting.

Pigmentation & Vitamin C

Vitamin C can block tyrosinase, which is critical in the formation of melanin. Tyrosinase is an enzyme, found in the skin, that triggers the release of pigment (melanin). Vitamin C can also reverse the hyperpigmentation caused by sun damage and post inflammatory hyperpigmentation caused by acne. It may take as long as 4–12 weeks to reduce pigmented spots with Vitamin C, but is key to both protection from developing as well as reducing pigmentation.
