Retinol is a popular skincare ingredient known for its powerful anti-ageing and skin-renewing benefits. In K-beauty, it is often used in gentle, hydrating formulations to minimise irritation while delivering its smoothing and brightening effects. Retinol helps improve skin texture, reduce fine lines, and promote a more even complexion by supporting natural cell turnover. Many K-beauty products combine retinol with soothing ingredients like hyaluronic acid and centella asiatica to keep the skin balanced and nourished, making it suitable even for those with sensitive skin.
