If you're using more than one serum, order matters. As a general rule, apply your products from thinnest to thickest consistency — this lets each layer absorb properly instead of sitting on top of the last.
Start with a water-based serum like our B3 Hydra Glow (niacinamide), which sinks in quickly and preps your skin for what comes next. Follow with a targeted treatment like Bright Monster (alpha arbutin) or Double Action (vitamin C) to address specific concerns like dark spots or dullness. Finish with your moisturizer to lock everything in.
One exception: vitamin C and niacinamide can be layered, but if your skin is sensitive, try alternating them between your AM and PM routine instead of stacking both at once.
Give each layer 30–60 seconds to absorb before moving to the next step, and always finish with SPF in the morning.
