Retinol is a vitamin A derivative that has become an increasingly popular ingredient in K-Beauty for its ability to improve skin texture and promote a smoother, more youthful-looking complexion. It works by encouraging skin cell turnover, helping to reduce the appearance of fine lines, wrinkles, uneven skin tone, and blemishes over time. In line with the K-Beauty philosophy, retinol is often formulated with soothing and hydrating ingredients to minimise irritation, making it suitable for gradual introduction into a skincare routine while supporting healthier, more radiant skin.
