Nutritionist's Take
COSRX Pure Vitamin C 23% Serum is a potent skincare product that combines vitamin C, a powerful antioxidant known for its brightening properties, with vitamin E and hyaluronic acid for enhanced hydration. The high concentration of vitamin C (23%) may effectively reduce dark spots and stimulate collagen production, which can improve skin texture and reduce fine lines. However, the potential for skin irritation should be considered, particularly for sensitive skin types. The formulation is free from animal testing, aligning with ethical consumerism principles. While the product offers promising benefits, individuals with specific skin concerns or conditions should consult a dermatologist before use. The overall healthiness of such a product largely depends on individual skin compatibility and goals; therefore, it's advisable to perform a patch test and consider the dosage and frequency of application.
COSRX Serums Editorial Review
The COSRX Pure Vitamin C 23% Serum is a potent liquid-based skincare product that brightens and hydrates the skin. Some customers have reported that the product has a strong smell, but this is normal for high-potency vitamin C products. While the manufacturer's instructions do not require refrigeration, it is recommended to store the product away from direct sunlight, heat, and humidity. Some customers have experienced skin irritation, rashes, and stickiness after using the product, and some find the hamster pee-like smell to be unpleasant. However, others report that it effectively fades hyperpigmentation and gives the skin a youthful glow.
