This starts the same way a Regular Manicure does, with shaping and cuticle care, but adds a scrub across the hands and lower arms before the massage. Dry skin builds up gradually from everyday things like hand washing, sun exposure, and weather, and exfoliation is what actually removes that buildup rather than just covering it with lotion.
The scrub used is a sugar-based exfoliant, gentle enough for daily use on skin but effective at lifting away that buildup. The massage that follows uses a shea-based hydrating cream, worked into the hands and lower arms rather than just the fingers.
If your nails are fine but your hands feel rough or tight, this addresses that directly instead of just polishing over it.
