Advanced Night Smoothing Serum With Retinol 1% in Squalane

The strongest concentration in this squalane-based trio, intended for skin that has already worked through gentler versions comfortably. One percent retinol is suspended in nourishing squalane, keeping the anhydrous fluid silky and helping offset the tightness that stronger retinoids can bring. Warm two or three drops between fingertips at bedtime, press them over clean skin, and leave a night or two between applications until things settle. Consistent evening use supports a smoother-looking surface and more uniform tone. Wear SPF every morning while you use it.
