COSRX - Oil Free Ultra Moisturizing Lotion with Birch Sap 100 ml

COSRX - Oil Free Ultra Moisturizing Lotion with Birch Sap (100ml)

This is a lightweight, hydrating daily moisturizer designed to calm irritation and replenish moisture without leaving a greasy residue. It is a cult favorite in the K-Beauty community, famously used to soothe skin after using strong active ingredients (like AHAs or BHAs).

Core Features & Benefits

• 70% Birch Sap Base: Instead of plain water, this formula uses 70.8% Birch Sap (Betula Platyphylla Japonica Juice), which mimics the skin's natural moisture factor to hydrate deeply and soothe inflammation.
• Truly Lightweight: It is designed to absorb almost instantly, leaving a fresh, satin finish rather than a heavy or sticky film.
• Soothing & Calming: Excellent for cooling down angry, red, or freshly exfoliated skin.
• Hygienic Packaging: Comes in a sleek pump bottle that keeps the product stable and makes dispensing sanitary.

Star Ingredients

• Birch Sap (Betula Platyphylla Japonica Juice): A nutrient-rich fluid containing amino acids, vitamins, and minerals that hydrates and calms the skin.
• Tea Tree Leaf Oil: Present in a small amount to help control sebum and fight inflammation (gives the product a very faint, fresh herbal scent).
• Glycerin & Betaine: Humectants that draw moisture into the skin to keep it plump.

Best For

• Oily & Combination Skin: The primary target audience. It provides necessary hydration without clogging pores or adding shine.
• Acne-Prone Skin: The "oil-free" formula prevents breakouts while the tea tree oil helps manage bacteria.
• Sensitive Skin: Useful for those who cannot tolerate heavy creams.
• Dry Skin (as a layer): For very dry skin, this works best as a hydrating serum layer underneath a heavier cream, rather than a standalone moisturizer.

Texture & Feel

• Consistency: A white, semi-translucent lotion that is slightly thicker than water but thinner than a cream.
• Finish: Non-greasy and matte-to-satin. It disappears into the skin within seconds.

How to Use

1. Cleanse and tone your face.
2. Apply your serums or chemical exfoliants (AHAs/BHAs).
3. Pump a small amount of the lotion (1-2 pumps) and smooth it over your face and neck.
4. AM: Follow with sunscreen.
5. PM: Use as your final step or layer a sleeping mask over it if you need extra moisture.
