COSRX The Retinol 0.5 Oil To reduce signs of aging, 20 ml

COSRX The Retinol 0.5 Oil is a night-time treatment that combines pure retinol 0.5% with plant-derived squalane and vitamin E to support collagen production, refine fine lines, improve skin elasticity, brighten dull complexion, and provide hydration. It targets early and advanced aging signs, loss of firmness, and acne-prone skin. How to use: Start gradually during evenings. After cleansing, apply 1–2 drops to the areas of concern (e.g., under eyes, around mouth, forehead, neck) or to the entire face after your moisturizer. Begin with 2–3 times per week and increase gradually to every other night, then nightly as tolerated. Adjust duration and frequency based on individual tolerance.
