Centifolia rose hydrosol (20%) has a soothing, anti-aging, and calming effect. LIRENE ACID POWER: These are innovative formulas containing a unique blend of cosmetic acids at a high concentration of 7% and soothing hydrosols. 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. A complex of glycolic, salicylic, and lactic acids (7%) stimulates the skin’s natural renewal processes, where keratinized skin cells are replaced by newer, younger ones. As a result, the skin becomes smoother to the touch, more elastic, and less prone to wrinkle formation and deepening. It stimulates the production of skin-supporting proteins, thanks to which fine lines are filled from within. Directions for use: Massage onto clean, dry skin in the evening, avoiding the eye and mouth area. Then apply your favorite Lirene cream. Depending on your preferences 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.
