COSRX Oil Free Ultra Moisturizing Lotion with Birch Sap – lightweight moisturizer with 70% birch sap
COSRX Oil Free Ultra Moisturizing Lotion with Birch Sap is a lightweight facial moisturizer designed for skin that needs comfort and hydration without a greasy feel. Its concept is straightforward: replacing a daily cream with a fast-absorbing, oil-free formula that is particularly well suited to combination and oily skin, while officially being presented as suitable for all skin types.
Birch sap is more than just part of the name
The formula’s standout feature is its 70% Betula Platyphylla Japonica birch sap content. It forms the foundation of the lotion and explains why the product focuses not on rich nourishment, but on lightweight hydration that does not weigh down the skin. The formula is also free from fragrances and contains 4-terpineol, a key component of tea tree that COSRX describes as helping reduce the risk of skin reactions and provide a soothing sensation. It is a streamlined formula in which birch sap, rather than a long list of active ingredients, remains the main focus.
- Hydration support: glycerin, betaine, sodium lactate, and sodium hyaluronate help attract and retain moisture, leaving the skin feeling less tight after application.
- Soothing duo: panthenol and allantoin complement the formula with properties that help support skin comfort—especially when the skin looks irritated or has lost its smoothness.
- Light protective layer: dimethicone and fatty alcohols provide slip and softness, while the lotion remains lightweight and free from plant-based and mineral oils.
At first, the milky lotion spreads easily, quickly losing the feel of a thicker emulsion. Once absorbed, it leaves the skin soft and smooth, without a noticeable greasy shine. It fits naturally into a routine after toner or essence, before a richer skincare product or sunscreen. It will appeal most to those looking not for a heavy cream, but for a well-balanced dose of everyday hydration defined not by oils, but by its high birch sap content.
Usage
After cleansing your face, take an appropriate amount of COSRX Oil Free Ultra Moisturizing Lotion with Birch Sap and gently apply it to your skin using upward, circular motions. Focus on areas that may require extra hydration, and allow the lotion to absorb fully into your skin before applying any additional products. For best results, use it twice daily, in the morning and evening, as part of your skincare routine to maintain optimal moisture levels and promote a healthy complexion.
