Thank you for viewing. Obagi C25 Serum Neo addresses multiple concerns, including pores*1, dullness*2, and fine lines caused by dryness*3 around the mouth, which become noticeable with age. This serum moisturizes the skin, leading to clear*4, firm, and radiant skin. Newly formulated with Advanced C Control. The high-penetration formula has been improved. How to Use: In the morning and evening, after preparing your skin with lotion, etc., take an appropriate amount (4-5 drops) onto your palm and gently apply it to your skin. Focus on areas of concern, such as dullness, and apply to the entire face, avoiding the eye area. Precautions for Use: ● Do not use on areas with wounds, swelling, eczema, or other abnormalities. ● Please use with caution to ensure that no abnormalities occur on your skin. If you experience redness, swelling, itching, irritation, loss of color (such as white spots), or darkening of the skin during or after use, or when exposed to sunlight, discontinue use and consult a dermatologist or other specialist. Continued use may worsen symptoms. ● Be careful not to get the product in your eyes. If it gets into your eyes, rinse immediately with water or lukewarm water. If any abnormalities persist, consult an ophthalmologist. ● You may experience a slight tingling sensation when the product penetrates the skin. This is usually temporary and not a cause for concern. If the sensation persists, discontinue use. Instant purchase is welcome. If you have any questions, please feel free to comment.
