Vitamin C is one of the most researched and widely used ingredients in skincare. It plays a central role in collagen production, pigmentation control and protection against environmental damage. When formulated and used correctly, Vitamin C can significantly improve skin brightness, firmness and overall resilience.
Vitamin C is an essential cofactor in collagen synthesis. It is required for the enzymes that stabilise and cross link collagen fibres. Without adequate Vitamin C, newly formed collagen is weaker and more prone to breakdown.
It is also a powerful antioxidant. This means it helps neutralise free radicals generated by ultraviolet exposure, pollution and daily oxidative stress.
Fibroblasts rely on Vitamin C to form strong, organised collagen fibres. Regular topical use supports:
• Increased collagen formation
• Improved firmness and elasticity
• Reduced fine lines over time
• Better wound healing and repair
This is one reason Vitamin C is often paired with retinoids and sunscreen in long term skin plans.
Vitamin C interferes with melanin production and helps brighten uneven skin tone. It does this by inhibiting tyrosinase, the enzyme involved in pigment formation.
With consistent use, Vitamin C can help improve:
• Dull skin tone
• Sun related pigmentation
• Post inflammatory marks
• Overall brightness and clarity
While sunscreen blocks ultraviolet radiation, Vitamin C reduces oxidative damage that occurs from residual exposure and pollution. This makes it a key part of daytime skincare routines.
The most studied form is L ascorbic acid. It is highly effective but can be irritating in higher concentrations and is less stable.
Gentler and more stable derivatives include:
• Sodium ascorbyl phosphate
• Magnesium ascorbyl phosphate
• Ascorbyl glucoside
These offer similar benefits with improved tolerability, particularly for sensitive skin.
Most people benefit from daily morning use. It is best applied before moisturiser and sunscreen.
People with very sensitive skin, rosacea, eczema or compromised barriers should introduce Vitamin C gradually.
Vitamin C is a cornerstone ingredient for collagen support, pigmentation control and environmental protection. It is not a quick fix, but when used consistently, it supports brighter, stronger and more resilient skin over time.
