Medik8 r-Retinoate Day & Night Eye Serum

r-Retinoate Day & Night Eye Serum is one of the most advanced vitamin A eye treatments currently available. It is powered by retinyl retinoate, Medik8's patented hybrid retinoid that is clinically proven to be 8x more powerful than standard retinol — yet remains gentle enough to use on the delicate eye area. The serum targets fine lines, dark circles and puffiness in one multi-action formula.

Retinyl retinoate is a hybrid retinoid molecule, patented and exclusive to Medik8, developed over eight years of research. Independent studies have shown it to be 8x more powerful than traditional retinol in delivering visible age-defying results. Crucially, it is also photostable, which means it does not lose its potency when exposed to sunlight — making it suitable for both day and night use.

Yes. Most traditional retinoids degrade in sunlight, which is why they are typically used only at night. Retinyl retinoate is uniquely photostable, so it remains active and effective when applied in the morning. You should always follow with a broad-spectrum SPF in the morning, as all vitamin A products encourage natural exfoliation and increase sun sensitivity.

Yes. While retinyl retinoate targets fine lines and skin texture, the formula also contains caffeine to help reduce the appearance of puffiness, and glucosyl hesperidin (derived from citrus fruits) to help brighten the look of dark circles. Multi-weight hyaluronic acid hydrates the delicate under-eye area for a plumper, smoother appearance.

Yes. Retinyl retinoate is widely regarded as one of the gentlest yet most effective forms of vitamin A available, making r-Retinoate Day & Night Eye Serum a good choice for those new to retinoids or with sensitive eye areas. As with any new active product, we recommend a patch test 24 hours before first use, and building usage up gradually — start every other day before moving to daily application.

Apply a small amount of r-Retinoate Day & Night Eye Serum around the eye area, focusing on the orbital bone — the bony ridge around the eye socket. Carefully avoid the eyelids and the inner corner of the eye. Use light tapping motions with your ring finger and allow the serum to absorb fully before applying any other products on top.

Yes. r-Retinoate Day & Night Eye Serum layers beautifully with the rest of your Medik8 routine. Apply after cleansing and any treatment serums, and layer Advanced Night Eye on top for additional nourishment. It pairs particularly well with the full-face r-Retinoate Day & Night Serum for accelerated whole-face age-defying results.

Yes — always. All vitamin A products encourage natural skin exfoliation, which can increase sensitivity to UV light. Although retinyl retinoate itself is photostable, your skin will still be more vulnerable to sun exposure while using any retinoid. We strongly recommend wearing a broad-spectrum SPF 30 or higher every morning, especially around the eye area.

No. This product contains a vitamin A derivative (retinyl retinoate), and topical retinoids are routinely advised against during pregnancy and breastfeeding as a precaution by healthcare professionals. We recommend discontinuing use if you become pregnant or are breastfeeding, and consulting your midwife, GP or obstetrician for guidance on suitable retinoid-free alternatives.
