Dr. C. Tuna Vitamin C Glow Serum 30ml is a radiance-boosting facial serum formulated with a potent concentration of stabilized vitamin C designed to deliver visible brightening, antioxidant protection, and collagen-stimulating benefits for a luminous, youthful complexion. Vitamin C in its most effective stabilized form works to neutralize free radicals generated by UV exposure and pollution, inhibit excess melanin production responsible for dark spots and uneven tone, and stimulate fibroblast activity that produces the collagen and elastin needed for firm, bouncy skin. Complementary brightening botanicals and hydrating hyaluronic acid enhance vitamin C's glow-giving effects while ensuring the skin remains plump, comfortable, and deeply nourished throughout the treatment process. The lightweight, fast-absorbing texture delivers these concentrated actives deep into the skin without leaving any sticky or heavy residue, making it ideal for layering under moisturizers and sunscreens.
