Cornflower hydrolates. A lactic and lactobionic acid complex (7%) penetrates the skin and stimulates its renewal. LIRENE ACID POWER: innovative formulas containing a unique blend of cosmetic acids at a high concentration of 7% and soothing hydrolates. The properly selected pH reduces the risk of skin irritation and unsightly flaking, allowing the cells to be regularly stimulated for renewal. As a result, the skin’s structure and tone gradually improve, and the face regains its youthful freshness and radiance. AHA / PHA acids: reduce imperfections and discoloration, regulate cell renewal, reduce wrinkles, unclog pores, and moisturize the skin structure. How to use: Massage onto clean, dry face in the evening, avoiding the eye and mouth area. Then apply your favorite Lirene cream. Depending on your preference and skin reaction, you can use the serum daily or several times a week. During use and for one week after completion, it is recommended to protect the skin with a high UV filter from sun exposure. Note: Do not use on damaged skin, during pregnancy or breastfeeding. A slight burning sensation may occur, which is a normal reaction. If the burning sensation persists after 2–3 minutes or the skin remains red after application, it is recommended to rinse off the product and discontinue use. Size: 30 ml
