Seoul 1988 Retinal Serum with 2% Retinal Complex and Black Ginseng Extract for Fine Line Care, 30ml

Seoul 1988 Serum by K-Secret is an advanced Korean formula combining 2% Liposomal Retinal with Black Ginseng Extract, designed to combat signs of aging and renew skin cells. - 2% Liposomal Retinal: An advanced form of retinol that penetrates deep into skin layers without irritation. It works to stimulate collagen, reduce fine lines, and improve skin texture. - Black Ginseng: One of the most powerful ingredients in traditional Korean skincare, known for its antioxidant properties. It gives the skin vitality and radiance while fighting signs of fatigue and tiredness. Size: 30 ml Suitable for nighttime use within a skincare routine. - Use at night only — because retinal increases skin sensitivity to sunlight. - Sunscreen (SPF) must be used in the morning after any night this serum was used. - It is recommended to start with light usage (twice a week) for skin that has not tried retinal before, then gradually increase frequency according to skin tolerance. - Avoid using it on skin with open wounds, sunburns, or active inflammation. - Not suitable for use during pregnancy or breastfeeding unless after consulting a doctor, as retinol derivatives may not be safe during this period. - It is preferable to perform a sensitivity test on a small area of skin before full facial use. - Avoid combining it with other products containing strong acids (such as AHA/BHA) or Vitamin C in the same routine to reduce the risk of irritation. - Store out of reach of children, in a cool place away from direct sunlight. - If severe redness, itching, or persistent irritation occurs, stop use immediately.
