What are the benefits of vitamin C for the skin?

Vitamin C, also known as ascorbic acid, plays a crucial role in our overall health.

This water-soluble vitamin, found mainly in fruits and vegetables, is an essential element in maintaining the health and radiance of our skin. In this article, we'll explore in detail the many benefits of vitamin C on the skin and why it's important to meet our needs for this vitamin.

Your body's vitamin C requirements

Vitamin C requirements vary from person to person, but it is generally recommended that adults consume between 75 and 110 mg of vitamin C per day. This vitamin is widely available in a variety of fresh fruits and vegetables, and a diet rich in these natural sources is recommended to meet daily requirements.

What role does vitamin C play on the face?

• Powerful antioxidant

Vitamin C acts as a powerful antioxidant, helping to protect the skin from damage caused by free radicals. Free radicals are unstable molecules produced by factors such as pollution, UV rays and oxidative stress. By neutralizing these free radicals, vitamin C helps prevent premature aging of the skin, such as wrinkles, age spots and sagging.

• Improved collagen synthesis

Vitamin C plays a crucial role in the production of collagen, an essential protein that maintains skin structure and elasticity. By stimulating collagen synthesis, vitamin C helps reduce the appearance of wrinkles and improve skin firmness, giving a younger, more radiant appearance.

• Boosts the skin's immune defences

Vitamin C is also beneficial for boosting the skin's immune defenses. It helps prevent skin infections and accelerate wound healing by promoting the production of immune cells. Healthy skin is better equipped to defend itself against external aggressors, such as bacteria and viruses, helping to maintain clear, radiant skin.

• Improved iron absorption

Vitamin C plays an essential role in theabsorption of iron, an important mineral for skin health. Iron deficiency can lead to anemia, often resulting in pale, dull skin. By improving iron absorption, vitamin C helps maintain healthy blood circulation, resulting in dewy, luminous skin.

What are the different types of vitamin C?

Ascorbic acid Ascorbic acid: This is the most common and basic form of vitamin C. It is easily absorbed by the body. It is easily absorbed by the body, but can be irritating to sensitive skin at high concentrations, and is sensitive to light and heat.

Sodium ascorbate Sodium ascorbate is a stabilized form of vitamin C. This form of vitamin C is often used in skin care products because of its greater stability than pure ascorbic acid. Sodium ascorbate is a combination of vitamin C(ascorbic acid) and sodium. This combination makes vitamin C more stable and less prone to oxidation when exposed to air and light, meaning it retains its effectiveness better in skin care products.

Sodium ascorbate's enhanced stability makes it a popular choice in skin care product formulations, as it guarantees consistent, prolonged efficacy. What's more, this form of vitamin C is generally better tolerated by sensitive skin compared to pure ascorbic acid, making it an attractive option for a wide range of skin types.

Magnesium ascorbate This form of vitamin C is bound to magnesium molecules, giving it greater stability and skin tolerance. It is often used in anti-aging skin care formulations.

Calcium ascorbate This form of vitamin C is also bound to calcium molecules, giving it greater stability. It is often used in skin care products designed to strengthen the cutaneous barrier and soothe sensitive skin.

Ascorbyl palmitate Ascorbyl palmitate is a fat-soluble form of vitamin C that is more stable than ascorbic acid. It is often used in skin care products designed to reduce the signs of aging and improve skin texture.

Ascorbyl glucoside This form of vitamin C is derived from ascorbic acid and glucose. It is known for its lightening and anti-spot properties, and is often used in skin care products designed to even out skin tone and reduce pigmentation spots.

Ascorbyl magnesium phosphate This form of vitamin C is derived from ascorbic acid and magnesium phosphate. It is often used in skin care products designed to reduce acne and regulate sebum production.
