Nº 4 · Night Serum
Nuit
0.1% Retinal
Retinal works several times faster than retinol because the skin has one conversion step to make instead of two. At 0.1% in a slow-release system, it does that without the peeling phase most people give up during.
Bisabolol and panthenol sit alongside it to keep the first fortnight tolerable. This is the only product in the routine with a run-in period, and it is worth respecting.
