Vitamin C Serum —What Can it do for my skin
Vitamin C is a powerful antioxidant that helps protect the skin from environmental damage caused by UV exposure and pollution. It works by neutralising free radicals, which contribute to premature ageing and skin damage.
Regular use of vitamin C can help brighten dull skin, reduce the appearance of pigmentation, support collagen production, and improve overall skin firmness. Over time, skin appears more even, radiant, and resilient.
How to Use a Vitamin C Serum Correctly
Vitamin C serums are best used in the morning, as they enhance the skin’s natural defence against environmental stressors throughout the day.
Apply vitamin C after cleansing and before moisturiser. Use 1–2 pumps and gently press it into the face, neck, and décolletage. Allow the serum to absorb fully before applying moisturiser and always finish with sunscreen to protect the skin and maximise results.
For sensitive or first-time users, start with application every second day and gradually increase to daily use as tolerated.
Different Forms of Vitamin C in Skincare
Not all vitamin C is the same. Different forms vary in strength, stability, and suitability for different skin types.
L-Ascorbic Acid
This is the pure, active form of vitamin C and the most researched. It is highly effective for brightening, collagen stimulation, and pigmentation reduction. However, it can be irritating for sensitive skin and is less stable, meaning it must be stored carefully.
Sodium Ascorbyl Phosphate (SAP)
A gentler, more stable form of vitamin C that is suitable for sensitive and acne-prone skin. SAP provides antioxidant benefits and helps brighten the skin with a lower risk of irritation.
Magnesium Ascorbyl Phosphate (MAP)
A water-soluble, stable form of vitamin C that supports hydration, skin tone improvement, and barrier function. Ideal for dry or sensitive skin types.
Ascorbyl Glucoside
A stable derivative that converts to active vitamin C within the skin. It offers gradual brightening and antioxidant benefits and is well tolerated by most skin types.
Choosing the Right Vitamin C for Your Skin
The best vitamin C serum depends on your skin type, concerns, and tolerance. Stronger formulations may deliver faster results but require careful use, while gentler derivatives provide consistent benefits with minimal irritation.
At Oceania Wellness, we recommend selecting vitamin C as part of a personalised skincare routine to ensure optimal results while maintaining skin barrier health.
