How to Use

Use PM only, 2-3 nights a week to start. Increase frequency as your skin builds tolerance. After cleansing and applying your hydrator, smooth a pea-sized amount into face and neck. Follow with your moisturiser of choice. Always use SPF in your AM routine. I NKEY Tip If you’re new to retinol or have sensitive skin, try the moisture sandwich method: a thin layer of moisturizer → a pea-sized amount of Starter Retinol Serum → a thin layer of moisturiser. For extra barrier care and maximum hydration, choose.

Heads Up: Retinoids can leave skin sensitive to the sun, so they should not be used in the AM. Always use SPF in your AM routine. When adding new products to your skincare routine, we always recommend patch testing.

Storage: Store in a cool, dry place (15–25°C). Keep out of direct sunlight. Avoid eyes. For external use only. Keep out of reach of children.
