COSRX Oil-Free Ultra Moisturizing Lotion with Birch Sap is a daily moisturizer designed for all skin types, especially beneficial for those with oily and combination skin. This lotion contains 70% Betula Platyphylla Japonica Juice, which prevents moisture loss and hydrates the skin effectively. Its weightless, fast-penetrating formula soothes irritated skin, restores moisture, and leaves the skin feeling fresh, soft, and silky smooth. This product is particularly good for maintaining hydration levels without adding excess oil or weight to the skin.
