COSRX Oil Free Lotion with Birch Sap is a daily acne facial moisturizer formulated to deliver lightweight hydration without clogging pores. The key ingredient, birch sap, is a naturally sourced fluid rich in minerals and amino acids that helps soothe and refresh the skin. This lotion is designed to maintain moisture balance while supporting a clear-looking complexion, making it suitable for all skin types, including oily and combination skin prone to blemishes.

The oil-free formula ensures a non-greasy finish, allowing the skin to feel soft and comfortable without a heavy residue. Its gentle composition avoids common irritants, making it a practical option for those who prefer minimalist, skin-friendly care. The product is free from artificial fragrances, parabens, and other harsh additives, focusing instead on hydration that respects the skin’s natural barrier.

This moisturizer can be used as part of a daily routine, applied after cleansing and toning to lock in moisture. Its light texture absorbs quickly, making it suitable for both morning and evening use. The 100ml (3.38 fl. oz) bottle provides a practical amount for regular application.
