COSRX Oil-Free Ultra-Moisturizing Lotion with Birch Sap (100ml) — Korean Lightweight Oil-Free Moisturiser with 70% Betula Platyphylla Japonica Juice, Sodium Hyaluronate, Panthenol & Allantoin | Deep Hydration Without Pore-Clogging | All Skin Types | Made in Korea

The Moisturiser That Finally Works for Oily Skin — Without Sacrificing Hydration

The problem with most moisturisers for oily skin is that they choose between two bad options: light enough to not feel greasy, but not hydrating enough to make a real difference — or deeply moisturising, but too rich and heavy for oily and acne-prone skin types. The COSRX Oil-Free Ultra-Moisturizing Lotion with Birch Sap, available at thealoy.com, exists to prove that this is a false choice.

By replacing standard purified water with 70% Betula Platyphylla Japonica (Birch Tree) Juice — a natural botanical liquid significantly richer in skin-active nutrients than water — the formula delivers deep, sustained hydration in a texture that absorbs instantly, leaves no greasy residue, and is 100% oil-free and non-comedogenic. The result: genuinely hydrated skin, in a lightweight lotion that oily, combination, and acne-prone skin types can use without hesitation.

Skin Type Suitability

• Oily and combination skin — oil-free formula absorbs instantly without adding shine; non-comedogenic means no pore congestion
• Acne-prone skin — hypoallergenic, oil-free, fragrance-free (latest formula); does not trigger breakouts
• Dry and dehydrated skin — Birch Sap, Sodium Hyaluronate, Panthenol, and Betaine deliver meaningful, sustained moisture
• Sensitive skin — hypoallergenic and dermatologist tested; Allantoin and Panthenol soothe reactive skin
• Normal skin — a lightweight daily moisturiser that maintains skin balance without heaviness
• All skin types post-exfoliation — ideal after AHA/BHA or retinol as a non-irritating, deeply hydrating recovery step

Who Is This Product For?

• Those with oily or combination skin who have given up on finding a daily moisturiser that genuinely hydrates without making skin greasy — this formula solves that problem
• People whose skincare routine includes active ingredients (AHA, BHA, Vitamin C, Retinol) who need a gentle, hydrating, non-irritating moisturiser that layers well without interfering with actives
• Skincare minimalists who want a high-quality, effective moisturiser in a clean, straightforward formula — 19 ingredients, all purposeful
• Those in Bangladesh searching for the best oil-free moisturiser for oily skin in Bangladesh or the original COSRX Birch Sap lotion in Bangladesh — now at thealoy.com

Who Should Avoid This Product?

• Those with known sensitivity to Tea Tree Oil or Lemon Peel Oil — the formula contains Melaleuca Alternifolia (Tea Tree) Leaf Oil and Citrus Medica Limonum (Lemon) Peel Oil, which carry natural fragrance and potential sensitivity for reactive skin. Patch test before full use
• Those expecting a rich, cream-type moisturiser — this is a lightweight lotion, not a cream. Those with very dry skin may need to layer a richer cream over this for evening use
• Pregnant women — contains Tea Tree Oil and Lemon Peel Oil; consult your dermatologist before use during pregnancy

Skin Concerns It Helps With

• Dehydration and moisture loss — 70% Birch Sap prevents moisture loss in the skin, making it more hydrated; Sodium Hyaluronate draws and retains deep moisture
• Oily, greasy skin from heavy moisturisers — 100% oil-free formula provides all the hydration without any of the heaviness that causes excess shine
• Post-active skin sensitivity — the gentle formula soothes irritated skin and restores moisture after chemical exfoliants or active serums
• Rough, uneven skin texture — Allantoin promotes cell renewal and smooths the skin surface; Birch Sap's mineral and enzyme content improves skin vitality
• Skin barrier weakening — Panthenol accelerates barrier repair; Dimethicone forms a protective film that locks moisture in and reduces trans-epidermal water loss
• Acne and congested pores — non-comedogenic, oil-free formula can be used daily by acne-prone skin without fear of triggering new breakouts

What Results Can You Realistically Expect?

Immediately: 2–3 pumps spread easily across the face, absorbing in seconds. Skin feels instantly fresh, soft, and silky smooth — not greasy, not tight. A lightweight moisture film remains without any residue.

Within 1 to 2 weeks: Skin maintains a more consistent moisture level throughout the day. Post-exfoliation irritation and tightness reduce. Skin texture improves as dehydration lines soften.

Long-term: Consistent daily moisturising with a non-comedogenic, barrier-supporting formula keeps oily skin balanced, acne-prone skin calmer, and all skin types visibly healthier and more resilient.

How to Use

1. After cleansing, toning, and applying any chemical exfoliants or actives
2. Take 2–3 pumps and apply evenly to the face
3. Gently pat the area where lotion was applied so it is absorbed along the skin texture — the patting technique improves absorption and prevents disturbing the preceding layers
4. Follow with your cream step or sunscreen (morning)
5. Can be used morning and evening as the moisturising step

Routine position (official COSRX): After cleansing → toning → chemical exfoliants → this lotion → cream → sunscreen

Ingredient Breakdown

Full Official Ingredient List (COSRX Official): Betula Platyphylla Japonica Juice (70%), Butylene Glycol, Glycerin, Dimethicone, Betaine, Cetearyl Alcohol, 1,2-Hexanediol, Cetearyl Olivate, Sorbitan Olivate, Ethylhexylglycerin, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Ethyl Hexanediol, Xanthan Gum, Allantoin, Panthenol, Sodium Hyaluronate, Sodium Lactate, 4-Terpineol, Water, Polysorbate 60, Sorbitan Isostearate, Citrus Medica Limonum (Lemon) Peel Oil, Melaleuca Alternifolia (Tea Tree) Leaf Oil

Betula Platyphylla Japonica Juice (70% — Birch Sap) The hero ingredient and the formula's base liquid. Birch Sap is harvested annually from birch trees and is rich in amino acids, minerals, enzymes, antioxidants, and vitamins — making it significantly more nutrient-dense than standard purified water as a moisturiser base. It prevents moisture loss in the skin, making it more hydrated, and its natural calming compounds soothe irritated skin. Birch Sap also contains natural xylitol, malic acid, and manganese, which collectively nourish the skin and support a healthy, balanced complexion.

Sodium Hyaluronate (Hyaluronic Acid) The most effective humectant in skincare. Draws and retains moisture from the environment into the skin, providing sustained hydration that keeps skin plump and comfortable throughout the day.

Panthenol (Vitamin B5) Converts to Pantothenic Acid in the skin — essential for barrier repair, moisture retention, and soothing of irritation and inflammation. Particularly valuable in a formula designed for post-exfoliation use.

Allantoin Soothes irritation, promotes skin cell renewal, and improves skin smoothness and texture. Works synergistically with Panthenol to provide a comprehensive calming and recovery effect.

Betaine A naturally derived amino acid humectant and osmoprotectant. Moisturises the skin and helps protect cells from dehydration stress, contributing to the formula's sustained moisture-holding effect.

Dimethicone A lightweight, breathable silicone that forms a non-occlusive protective film on the skin surface — reducing trans-epidermal water loss and contributing to the soft, silky, non-greasy skin feel that makes this lotion so wearable.

Cetearyl Olivate & Sorbitan Olivate Natural olive oil-derived emulsifiers that create the formula's stable, lightweight emulsion and contribute a skin-conditioning feel after absorption.

Sodium Lactate A natural humectant derived from lactic acid fermentation. Draws and retains moisture, contributes mild exfoliating properties at low concentrations, and improves overall skin texture softness.

Melaleuca Alternifolia (Tea Tree) Leaf Oil & Citrus Medica Limonum (Lemon) Peel Oil Naturally antimicrobial and antioxidant botanical oils used at low concentrations for their skin-clarifying properties. Both carry natural scent and should be noted by those with essential oil sensitivity.

Frequently Asked Questions

Is this really "oil-free" if it contains Tea Tree and Lemon Oil? The "oil-free" claim refers to the absence of heavy comedogenic oils like mineral oil, castor oil, or fatty plant oils that clog pores and cause shine. Tea Tree Oil and Lemon Peel Oil are used in trace amounts for their clarifying properties and do not contribute to the greasy texture or comedogenicity associated with heavier oils.

Can I use this with active ingredients like AHA, BHA, Vitamin C, or Retinol? Yes — COSRX specifically recommends using this after cleansing, toning, and chemical exfoliants. It is one of the most widely used moisturisers in active-ingredient-heavy Korean skincare routines precisely because its gentle, non-irritating formula does not interfere with actives.

Does this work for acne-prone skin? Yes — it is one of the most popular oil-free moisturisers for acne-prone skin. The non-comedogenic formula, oil-free base, and Tea Tree Oil's mild antibacterial properties make it appropriate for daily use on breakout-prone skin.

How many pumps should I use per application? COSRX recommends 2–3 pumps for the full face. This is sufficient for an even, lightweight layer without wastage.

How long does 100ml last? With twice-daily use of 2–3 pumps, 100ml typically lasts 6 to 8 weeks.
