Dr. Althea Gentle Vitamin C Serum is a brightening facial serum designed to support dull, uneven and tired-looking skin. The gentle formula helps improve the appearance of dark spots, uneven tone and lack of radiance while keeping the skin comfortable for daily use. Vitamin C is commonly used in skincare to support a brighter-looking complexion, antioxidant care and a more even skin tone. The lightweight serum texture absorbs smoothly and layers well under moisturiser and sunscreen, making it suitable for morning or evening skincare routines. It is ideal for users looking to add a mild brightening step to their routine without a heavy or sticky feel.
