Quick Answer
Always use cleansing oil first, then follow with a glycolic acid serum on clean, dry skin. This order ensures the oil removes makeup and impurities without blocking the serum's absorption.
Why Order Matters for Exfoliating Serums
Layering skincare products in the wrong order can reduce effectiveness or cause irritation. A glycolic acid serum works best when applied to bare, freshly cleansed skin so the active ingredients can penetrate evenly. If you apply it before cleansing, the oil and residue on your face will block absorption and dilute the formula.
Cleansing oil is designed to dissolve sunscreen, makeup, and excess sebum. Using it first preps the skin so the glycolic acid can reach the surface cells it needs to exfoliate. This two-step approach is especially helpful if you wear heavy SPF or waterproof makeup.
Choosing the Right Products for Your Skin Type
Not all cleansing oils and exfoliating serums are created equal. A squalane-based oil is lightweight and non-greasy, making it suitable for most skin types, including oily and combination skin. Squalane mimics the skin's natural oils, so it removes impurities without stripping moisture.
For the exfoliating step, a 5% glycolic acid solution is a common starting concentration. It stimulates cellular renewal and helps fade uneven tone and pigmentation, but it should be used gradually if your skin is new to acids. Always patch test a new serum before incorporating it into your routine.
Step-by-Step Layering Routine
- Start with dry hands and dry face: Apply 2–3 pumps of cleansing oil to dry skin. Gently massage in circular motions for 30–60 seconds to break down makeup, sunscreen, and surface oils. Do not wet your face first — water prevents the oil from properly dissolving waterproof products.
- Emulsify and rinse thoroughly: Add a small amount of warm water to your hands and continue massaging. The oil will turn milky as it emulsifies. Rinse with lukewarm water and pat your face dry with a clean towel. Skipping the emulsification step can leave a residue that may block your serum.
- Apply glycolic acid serum to clean, dry skin: Dispense 2–3 drops of the glycolic acid serum onto your fingertips and press gently onto your face and neck, avoiding the eye area. Allow it to absorb for 30–60 seconds before applying any other products. Do not apply serum while skin is still damp — this can dilute the acid and increase the risk of irritation.
- Wait before layering additional products: Let the serum fully absorb before applying moisturizer or sunscreen. This waiting period prevents pilling and ensures the exfoliating ingredients have time to work. If you apply moisturizer too soon, you may push the serum around unevenly instead of letting it settle.
