Your skincare routine might be working against you and you don’t even know it.
your skin operates on a 24 hour biological clock. during the day it’s in defense mode, protecting itself from UV, pollution, and free radicals. at night it switches completely, collagen production peaks, cell turnover accelerates, and it absorbs active ingredients up to twice as effectively.
this is why retinol at night isn’t just about sun sensitivity. your skin is literally more receptive to it after dark. the cellular machinery retinol activates is already running at full speed while you sleep.
antioxidants and SPF in the morning. retinol, peptides, and rich moisturizers at night. not just convention. actual biology.
