Using Retinol in your PM skincare routine helps to kick start your skin renewal process whilst boosting overall skin clarity and uneven skin tone for a brighter, more even complexion. As we age, our natural collagen production starts to diminish which can lead to fine lines and wrinkles. Retinol works beneath the skin surface to promote renewal and repair processes so that newer cells reach the surface quicker, making skin appear more youthful. Both products in our Beginners Retinol Duo contain slow release Vitamin A derivatives that helps to avoid irritation, making them a perfect match for those new to using Retinol or who have more sensitive skin. Each Beginners Retinol Duo contains: Starter Retinol Serum (30ml) & Retinol Eye Cream (15ml).
