This is a high-end repair anti-aging serum with PDRN (polydeoxyribonucleotide) as the core repair ingredient, compounded with multiple peptides for synergistic anti-aging effects. It is specially designed for skin with fragile barrier and early aging signs. PDRN can penetrate deep into the skin base to help repair damaged barriers, soothe redness, dryness and fragility caused by external stimuli, and improve the skin's own tolerance and self-healing ability. Combined with various peptides such as acetyl hexapeptide and tripeptide, it helps improve dynamic lines and dry lines, enhances skin firmness and elasticity, and improves laxity, fatigue and dullness. The formula also adds sodium hyaluronate, panthenol and centella asiatica extract to boost moisturizing and soothing effects, reduce irritation, and make anti-aging repair gentler, suitable for sensitive and barrier-damaged skin. It has a clear slightly thick serum texture, spreads smoothly and absorbs well, non-sticky and non-clogging. It can be used morning and evening, or paired with post-procedure repair care. It is recommended to take 3-4 drops and press gently until absorbed after cleansing and toning, followed by a cream to lock in moisture. Long-term use strengthens the barrier, smooths fine lines, firms contours, and leaves the skin plump, elastic and healthy.
