Retinol is a powerful skincare ingredient known for its ability to visibly reduce the signs of aging. Derived from vitamin A, retinol works by increasing cell turnover, which helps to smooth fine lines, even out skin tone, and improve texture. It also stimulates collagen production, leading to firmer, more youthful-looking skin over time. Suitable for most skin types, retinol is particularly effective for those looking to address concerns like wrinkles, hyperpigmentation, and uneven skin texture. Start with a lower concentration to allow the skin to adjust, and always pair with sunscreen during the day, as retinol can make the skin more sensitive to sunlight.
