ESK Vitamin C Forte is a high-strength antioxidant serum formulated with 16% L-Ascorbic Acid, the pure form of vitamin C. Developed for normal, dry and mature skin, it helps improve skin brightness, promote a more even-looking complexion and support healthier-looking skin.

The formula combines L-Ascorbic Acid with vitamin E and ferulic acid. Vitamin E provides additional antioxidant support, while ferulic acid helps improve the stability of L-Ascorbic Acid, allowing the formula to remain effective for longer. Together, these ingredients create a balanced antioxidant serum designed to help maintain skin radiance and improve the appearance of uneven skin tone, pigmentation and the early visible signs of skin ageing.

L-Ascorbic Acid also supports normal collagen formation, helping to maintain skin firmness and elasticity while improving the overall appearance and texture of the skin with continued use.

ESK Vitamin C Forte is packaged in an opaque, airless bottle to minimise exposure to light and air, helping preserve the potency and stability of the active ingredients. Due to the inclusion of ferulic acid, the serum has a characteristic smoky aroma during application, which is completely normal and subsides quickly.

Because of its high concentration of pure L-Ascorbic Acid and naturally low pH, ESK Vitamin C Forte is best suited to normal, dry and mature skin and is generally not recommended for sensitive, reactive or rosacea-prone skin.
