How to Use Step 1. Cleanse your face and gently pat your skin dry before applying The Ordinary Hyaluronic Acid 2% + B5 - 30ml. Use this serum after cleansing and before heavier skincare products such as moisturisers, creams or oils. Step 2. If you are using The Ordinary Hyaluronic Acid 2% + B5 - 30ml for the first time, perform a patch test before applying it to your face. Apply a small amount to a discreet area and check for any signs of irritation before regular use. Step 3. Apply a few drops of the serum to your face and neck using clean fingertips. A small amount is enough to cover the application area. Step 4. Gently smooth the serum over your skin, avoiding direct contact with your eyes. Allow the product to absorb before applying your next skincare step. Step 5. Follow with a moisturiser to help complete your skincare routine. Apply creams, oils or other heavier products after The Ordinary Hyaluronic Acid 2% + B5 - 30ml. Step 6. Use the serum morning and evening as part of your daily skincare routine. Step 7. If using the serum in the morning, apply a broad-spectrum sunscreen as the final step of your skincare routine before makeup or sun exposure. Step 8. Close the bottle securely after each use and store it in a cool, dry place. If irritation occurs, discontinue use and seek advice from a healthcare professional if needed.
