What is Vitamin C?

It is an essential antioxidant for skin health, but since our bodies do not naturally produce it, it needs to be sourced externally. Topical application is the most effective way to increase skin Vitamin C levels as oral supplementation is a far less effective way to reap the benefits of this product.

Sodium Ascorbyl Phosphate (SAP) is a stabilised form of Vitamin C. This version is easier to use in formulations, as it doesn’t degrade quickly unlike some other versions of the product.

What are the benefits of using Vitamin C on your skin?

By helping reduce fine lines, wrinkles and other signs of ageing, Vitamin C is essential for maintaining healthy skin. It’s well known for its antioxidant properties, which help reduce the appearance of aging signs and brighten skin tone for a smoother, more luminous look. It shields against oxidative damage and helps reduce the effects of exposure to UV.

Also known to brighten dull skin tone and even out complexion, it can help lighten hyperpigmentation and age spots, while encouraging collagen production, which can give skin a firmer, more youthful appearance.

What are the benefits of using Vitamin C on your hair?

Added to shampoos and conditioners, it can help stop dyed hair from fading and protect the intensity of the original colour used.

How to use Vitamin C

Use 0.2% to 2% as an antioxidant, or 3% to 5% as a skin lightening active. Can be added up to 10%. This is a stable form of ascorbic acid which is water soluble. Heat sensitive, preferably to be added at cool-down stage at temperatures below 40°C. Most stable above pH 6.5.

It is a great addition to anti-aging products, eye creams, lotions, gels and brightening and rejuvenating serums.

History and origins of Vitamin C

Naturally occurring Vitamin C is mostly found in citrus fruits but is also found in other fruits and vegetables. As the human body doesn’t produce it naturally, it is classed as an essential nutrient and needs to be consumed from other sources.

A lack of Vitamin C has been known for centuries to cause scurvy, and sailors over the years learned to plant citrus trees along trade routes to ward this off on their travels.

How is Vitamin C made?

Ascorbic acid rapidly oxidises to Dehydroascorbic acid and presents an orange colour. This reaction can be reversed by other antioxidant agents.
