Yes, you can mix hyaluronic acid and retinol in your skincare routine. Hyaluronic acid provides hydration and moisture retention, while retinol for skin helps encourage skin cell turnover and reduces the look of fine lines and wrinkles. First, apply retinol to a cleansed, dry face and allow it to melt into the skin. Follow with a hyaluronic acid serum to replenish skin moisture and counteract the drying effect some experience from retinol usage. Hyaluronic acid can form part of both your AM and PM skincare regimes, while retinol application should be reserved for the evening as it causes photosensitivity. Learn more about introducing retinol into your routine with our retinol for beginners guide - the key is to start slowly with a suitable concentration and build up the frequency with time.
