How to Use Step 1. Cleanse your face and gently pat your skin dry before applying The Ordinary Sulfur 10% Powder-to-Cream Concentrate. Use this treatment on clean skin before applying moisturiser or other heavier skincare products. Step 2. If you are using The Ordinary Sulfur 10% Powder-to-Cream Concentrate 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 small amount of the powder-to-cream treatment directly to targeted areas of skin. Avoid the eye area, lips and any broken or irritated skin. Step 4. Gently spread the product over the skin until the powder transforms into a cream texture. Do not rinse off. Step 5. Allow the treatment to absorb before applying other skincare products. Follow with moisturiser if needed. Step 6. Use The Ordinary Sulfur 10% Powder-to-Cream Concentrate as directed. Start with less frequent use if your skin is new to sulphur treatments and increase as tolerated. Step 7. In your morning routine, apply a broad-spectrum sunscreen as the final step of your skincare routine before makeup or sun exposure. Step 8. Avoid using The Ordinary Sulfur 10% Powder-to-Cream Concentrate in the same routine as other strong active treatments, exfoliating acids or retinoids unless advised by a skincare professional. Step 9. Close the container 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.
