Where does this serum fit in my skincare routine?

Apply it after cleansing and toning, before heavier creams or moisturizers. The silicone-based formula absorbs quickly and creates a smooth, lightweight layer that doesn’t interfere with products applied on top. If you’re using other active ingredients like glycolic acid or vitamin C, avoid layering them on the same application as retinol until your skin is fully adjusted — alternating evenings is a practical approach. Because this serum is lightweight and non-greasy, many users find it works well as a standalone treatment without needing a separate moisturizer on top, though you can certainly layer one if your skin runs dry.
