We need moisturizer because it helps maintain the skin’s barrier function by preventing water loss (transepidermal water loss) and replenishing lipids that keep the skin soft, smooth, and protected from dryness, irritation, and environmental damage.

Cold air, low humidity, and indoor heating strip moisture from the skin’s outer layer, damaging its natural lipid barrier. As a result, water evaporates faster (a process called transepidermal water loss), leaving the skin dry, tight, and flaky. Using hydrating ingredients like hyaluronic acid, ceramides, and emollients helps restore balance.

Exfoliation removes dead skin cells from the surface, promoting cell renewal and improving texture and radiance. Regular exfoliation helps unclog pores and enhances the absorption of serums and moisturizers. However, over-exfoliating can disrupt the skin barrier, leading to redness and sensitivity — moderation is key.
