After cleansing, toning, and applying any face serums, dispense a pearl-sized amount onto the ring finger. Gently tap and press the serum around the entire eye area—under the eyes, on the brow bone, and at the outer corners—until fully absorbed. Use morning and evening. Always follow with a moisturiser, and during the day, apply a broad‑spectrum sunscreen and wear sunglasses to protect the newly treated area from UV exposure. When incorporating Retinal into your routine, start by using every other night and gradually increase to nightly use as your skin builds tolerance.
