Ready for serious brightening and anti-ageing results? Our 15% Vitamin C serum harnesses one of the most effective concentrations available in modern skincare. At 15%, vitamin C (often in the form of L-ascorbic acid or a well-stabilised derivative) delivers clinically supported brightening, collagen stimulation and antioxidant defence — striking an optimal balance between potency and tolerability for most users. This high-strength formula targets dullness, dark spots, uneven tone and early signs of ageing while helping protect skin from daily environmental aggressors.
Why 15% Vitamin C Is a Gold-Standard Concentration
Vitamin C is one of the most researched skincare actives, renowned for neutralising free radicals, inhibiting melanin production and supporting collagen synthesis. At 15% — a concentration frequently cited as highly effective in studies and leading formulas — it provides powerful visible improvements without the extreme irritation risk of 20%+ levels:

Brightens complexion by fading hyperpigmentation, sun spots, post-acne marks and melasma
Stimulates collagen production to improve firmness, elasticity and the appearance of fine lines
Offers robust antioxidant protection against UV, pollution and oxidative stress
Evens skin tone for a more luminous, youthful radiance
Enhances overall skin texture and resilience when used consistently

Dermatological insights and product testing show that 10–15% vitamin C delivers measurable brightening, tone evening and firmness improvements within 4–8 weeks, with progressive anti-ageing benefits over 12+ weeks. This concentration is particularly popular for normal-to-resilient skin types seeking maximum results — often paired with stabilisers like vitamin E and ferulic acid for enhanced efficacy and longevity.
