Have you been seeing vitamin c as an ingredient and staple in pretty much every skincare routine? Do you ever wonder why this is so? Did you also have the same thought as I had before - What does Vitamin C do for skin and do I really need it?
The short answer is yes - but there are different types of vitamin c and we'll focus on the kind that has had the most studies done on it which is called L-Ascorbic Acid or ascorbic acid.
Vitamin C is not just there to strengthen our immune system, It also helps us in many other ways and this includes our skin. We'll dive into what Vitamin C ( L-ascorbic acid ) does for our skin and what skin benefits it provides.
WHAT IS L-ASCORBIC ACID?
L-ascorbic acid is known to be a powerhouse ingredient that’s synthetically derived or naturally found in fruits and vegetables. L-ascorbic acid is also known as a pure form of Vitamin C. This acid is often found in topical skincare products and usually found in a concentration between 3- 20%. A higher concentration of L-ascorbic acid can be irritating to the skin, and the low pH in some vitamin c serums may also cause some irritation.
L-ascorbic acid is an effective antioxidant which helps in brightening skin tone and reduces appearance of signs of aging by promoting collagen production in skin and protecting it from damage. It can usually be found in fruits and vegetables such as oranges, broccoli, leafy greens, grapefruit and peppers. They are also known to be a great source of dietary Vitamin C.

Products containing L-ascorbic acid aid in collagen synthesis. Collagen is the foundation of our skin, so the increased collagen can improve skin firmness and may help with preventing acne scars.
Vitamin C also inhibits excess melanin production to protect against dark marks or hyperpigmentation. Vitamin C can also reverse some skin damage and prevent skin damage and works best when used with sunscreen.
