COSRX Pure Vitamin C 13% Serum with Vitamin E & Hyaluronic Acid, Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 0.67fl.oz/20ml, Korean Skin Care
It's stinky. It's more runny than other hyaluronic acid I've used. But it doesn't make my face oily or dry or super red.
Vitamin Basics & Tips
Vitamin C, a potent antioxidant, plays a crucial role in collagen synthesis and skin brightening. Unlike hyaluronic acid which focuses on hydration, vitamin C serums combat free radicals from UV exposure and pollution, reducing signs of aging. Its instability in formulations often causes oxidation, which may explain the "stinky" odor mentioned in reviews – a sign to store it in cool, dark places.
When combining vitamin C with other actives like hyaluronic acid (as referenced in the review), apply vitamin C first on dry skin for optimal absorption. The "runny" texture described suggests a water-based formula, ideal for layering under moisturizers. While some users dislike thin consistencies, this characteristic helps prevent pore-clogging oiliness.
For sensitive skin types (as implied by the redness avoidance), 10-15% L-ascorbic acid concentrations balance efficacy with tolerance. The review's emphasis on non-drying effects aligns with vitamin C's ability to strengthen skin barrier function when properly formulated with pH-balanced solutions.
