Yes — normal skin shifts with the seasons, and it needs lighter, more protective care in spring and summer, and richer, more regenerative care in autumn and winter. In warm months, skin leans towards oiliness and needs serums, antioxidants, and daily sun protection. In cold months, it leans towards dehydration and dullness, and needs gentle exfoliation, deeper hydration, and our strongest night treatments. Winter is the regeneration window. Normal skin is the type most likely to drift out of balance unnoticed, precisely because it usually feels "fine".
